How to Refinance with a High Debt-to-Income Ratio: DTI Strategies [2026]

According to Mo Abdel, NMLS #1426884, a high debt-to-income ratio is the single most common reason refinance applications are denied—yet the majority of high-DTI borrowers who are denied at one lender qualify at another lender offering the same loan program. The Consumer Financial Protection Bureau reports that DTI exceeding 43% accounts for the largest share of mortgage denials, but the 43% threshold is not the universal limit many borrowers assume. Fannie Mae’s Desktop Underwriter approves conventional refinances at DTI ratios up to 50% when compensating factors are present. FHA automated underwriting extends to 56.99% DTI with strong compensating factors documented in the file. VA loans use residual income rather than a hard DTI cap, regularly approving veterans at 55–60% DTI when monthly residual income exceeds VA minimums by 20% or more. The critical variable is not your DTI ratio itself—it is which lender processes your application, because DTI overlay policies vary by 5–10 percentage points across institutions offering identical loan programs. A wholesale mortgage broker comparing DTI policies across 200+ lenders identifies which institutions offer the most favorable DTI limits, compensating factor requirements, and debt exclusion rules for your specific financial profile.

From My Practice: High DTI Denials Are Almost Always Lender Selection Failures

I have helped hundreds of borrowers refinance successfully with DTI ratios between 45% and 55%—borrowers who were told by their current lender that they “don’t qualify.” The pattern is remarkably consistent: the borrower applies at a bank or credit union with a 47% DTI, gets denied because that institution caps conventional DTI at 43% (a lender overlay, not a Fannie Mae requirement), and assumes they cannot refinance at all. When I run the same file through Fannie Mae Desktop Underwriter at a lender with no DTI overlay, DU issues an Approve/Eligible finding because the borrower has a 740 credit score, 4 months of reserves, and an LTV of 72%. The approval was always available—it just required the right lender. Comparing DTI policies across 200+ lenders through my wholesale channel is not a marginal advantage for high-DTI borrowers; it is the deciding factor between approval and denial. — Mo Abdel, NMLS #1426884

Understanding DTI: How Lenders Calculate Your Debt-to-Income Ratio for Refinancing

Debt-to-income ratio is the percentage of your gross monthly income consumed by monthly debt payments. Lenders use DTI as a primary risk indicator because it measures your capacity to absorb the new mortgage payment alongside existing financial obligations. Understanding exactly how lenders calculate DTI—and which debts are included or excluded—is the first step toward qualifying for a refinance when your ratio is elevated.

Front-End DTI (Housing Ratio) Calculation

Front-end DTI, also called the housing ratio, measures only housing-related costs divided by gross monthly income. The calculation includes: principal and interest on the new mortgage, property taxes (monthly equivalent), homeowners insurance (monthly equivalent), any HOA or condo association dues, mortgage insurance premiums (PMI for conventional, MIP for FHA), and any flood insurance. For a borrower earning $10,000/month gross income with a proposed housing payment of $3,200, the front-end DTI is 32%.

Back-End DTI (Total Ratio) Calculation

Back-end DTI is the number most lenders focus on for refinance qualification. It includes the front-end housing costs plus all recurring monthly debt obligations: car payments, student loan payments (minimum or income-driven repayment amounts), credit card minimum payments, personal loan payments, child support obligations, alimony or spousal support, and any other debts reporting on credit. The same borrower with $3,200 in housing costs and $2,100 in monthly debts has a back-end DTI of 53% ($5,300 / $10,000).

Understanding which debts count toward DTI is critical for high-DTI borrowers. For a deeper look at how debts interact with home equity products, see our home equity loan DTI requirements guide.

What Is NOT Included in DTI

Several common expenses are not counted in the DTI calculation: utilities (electric, gas, water, internet), health insurance premiums, auto insurance, grocery and food expenses, childcare costs (unless court-ordered), cell phone bills, gym memberships, and subscription services. The exclusion of these expenses is why DTI does not tell the full story of a borrower’s financial capacity—a point that VA’s residual income analysis specifically addresses by accounting for living expenses beyond just credit report debts.

Compensating Factors That Overcome a High DTI Ratio

Compensating factors are the documented strengths in your loan file that demonstrate your ability to manage the mortgage payment despite a high DTI. Both automated underwriting systems and manual underwriters evaluate compensating factors when deciding whether to approve a high-DTI application. The stronger your compensating factors, the higher the DTI ratio you can qualify at.

The Most Impactful Compensating Factors for High DTI Refinances

Cash reserves: Liquid assets remaining after closing that cover 3–6+ months of the proposed mortgage payment. Reserves are the strongest single compensating factor because they demonstrate a financial cushion if income disruptions occur. For a $3,000/month payment, $18,000 in reserves (6 months) significantly strengthens a 48% DTI file.
High credit score: A credit score of 720 or above demonstrates consistent debt management history, which directly offsets the risk associated with a higher DTI. Borrowers with 760+ credit scores receive the most flexibility on DTI thresholds in automated underwriting.
Low loan-to-value ratio: An LTV below 75% means the borrower has substantial equity in the property, reducing the lender’s risk. Combined with high DTI, low LTV signals that the borrower has accumulated significant wealth despite carrying higher monthly obligations.
Minimal payment shock: When the proposed new payment is equal to or less than the current mortgage payment, the borrower has already demonstrated the ability to manage that payment level. No payment shock is a powerful compensating factor for high-DTI refinances.
Stable employment history: Two or more years with the same employer (or in the same industry with progressive advancement) demonstrates income reliability and career stability.
Conservative use of credit: Low credit utilization ratios (below 30% of available credit) combined with no late payments in the past 24 months demonstrates disciplined financial behavior despite the high DTI.

Borrowers exploring whether a debt consolidation refinance makes sense should evaluate compensating factors first, because strong compensating factors may allow you to refinance at your current DTI without needing to consolidate.

Real Scenario: 49% DTI Approved with Strong Compensating Factors

A public school administrator in Orange County came to me after being denied by her credit union for a rate-and-term refinance. Her DTI was 49% due to student loan payments and a car loan. The credit union had a 43% DTI overlay and would not budge. Her file had three strong compensating factors: a 755 credit score, 5 months of reserves ($19,000 in savings), and an LTV of 68% on her Irvine townhome. I submitted the identical file through Fannie Mae Desktop Underwriter at a wholesale lender with no DTI overlay. DU issued an Approve/Eligible finding on the first submission. The borrower closed her refinance 29 days later and reduced her mortgage payment by $380/month. Her DTI did not change—her lender changed. That is the wholesale broker advantage for high-DTI borrowers. — Mo Abdel, NMLS #1426884

Automated Underwriting (DU/LP) vs Manual Underwriting for High DTI Borrowers

The underwriting method used to evaluate your refinance application has an enormous impact on how high your DTI can go. Automated underwriting systems (AUS) like Fannie Mae’s Desktop Underwriter (DU) and Freddie Mac’s Loan Product Advisor (LP) use algorithm-based risk assessment that considers your entire loan profile, not just DTI in isolation. Manual underwriting applies rigid DTI caps that are significantly lower.

Fannie Mae Desktop Underwriter: The 50% DTI Pathway

Fannie Mae’s DU system evaluates your credit score, LTV, reserves, employment stability, payment history, and DTI as an integrated risk profile. When DU determines that the overall risk is acceptable, it issues an “Approve/Eligible” finding—even at DTI ratios up to 50%. The key insight is that DU does not apply a single DTI cutoff. Instead, it dynamically weighs all factors: a borrower with a 50% DTI, 780 credit score, 60% LTV, and 6 months of reserves may receive an Approve/Eligible finding, while a borrower with 47% DTI, 660 credit score, 90% LTV, and no reserves may receive a Refer finding.

If DU issues a Refer finding, the loan cannot be delivered to Fannie Mae through the automated pathway. At this point, the options are: restructure the loan (increase down payment, pay off debts, add a co-borrower), submit through FHA automated underwriting (which has higher DTI tolerance), or explore Non-QM programs. Manual underwriting for conventional loans caps DTI at 36% front-end and 45% back-end with compensating factors—significantly more restrictive than the automated pathway.

Freddie Mac Loan Product Advisor

Freddie Mac’s LP system operates similarly to DU but with its own risk model. LP issues an “Accept” finding for approved loans and can also approve DTI ratios up to 50% when compensating factors support the risk assessment. Some lenders are Freddie Mac-only sellers, meaning they only run files through LP. Because DU and LP use different algorithms, a file that receives a Refer from DU may receive an Accept from LP, or vice versa. A wholesale broker who knows which lenders use which AUS system can strategically route your high-DTI file to the platform most likely to produce a favorable finding.

For borrowers with credit challenges alongside high DTI, understanding refinance credit requirements helps contextualize how credit score and DTI interact in the automated underwriting decision.

FHA DTI Limits and High DTI Refinancing Strategies

FHA loans are the most DTI-flexible government loan program for refinancing, with automated underwriting approving DTI ratios up to 56.99% in some cases. This makes FHA a powerful option for borrowers whose DTI exceeds conventional program limits.

FHA Automated Underwriting DTI Flexibility

When submitted through FHA’s Total Scorecard (the automated underwriting system for FHA loans), refinance applications with DTI ratios between 43% and 56.99% can receive an “Accept” finding when compensating factors are present. The compensating factors FHA evaluates include: verified cash reserves equal to at least 3 months of mortgage payments, minimal increase in housing payment (limited payment shock), residual income meeting or exceeding FHA benchmarks, and a strong credit profile with no significant derogatory credit events in the past 24 months.

FHA manual underwriting applies stricter limits: 31% front-end DTI and 43% back-end DTI as the standard caps, with extension to 40% front-end and 50% back-end when the borrower documents specific compensating factors. Manual underwriting is triggered when the automated system issues a Refer finding, the borrower has no credit score, or the borrower has recent significant derogatory credit (foreclosure, bankruptcy).

FHA Streamline Refinance: Bypass DTI Entirely

The FHA streamline refinance is one of the most powerful tools for high-DTI borrowers who currently have an FHA loan. The streamline process does not require income verification or DTI calculation when the refinance provides a net tangible benefit (lower payment or conversion from ARM to fixed rate). This means a borrower with a 60% DTI can refinance their existing FHA loan through the streamline process as long as they have been current on payments for 12 months and the new terms reduce their monthly obligation.

VA Residual Income: Why Veterans Have the Strongest High DTI Refinance Option

VA home loans offer the most borrower-friendly approach to DTI of any major loan program. While the VA Lender’s Handbook uses 41% DTI as a guideline, this is not a hard cap—VA underwriters evaluate residual income as the primary qualification measure, and veterans who meet residual income thresholds can exceed 41% DTI routinely.

How VA Residual Income Works

Residual income is the money remaining each month after subtracting all major financial obligations from net (take-home) income. The VA publishes minimum residual income tables based on two variables: family size and geographic region (the VA divides the country into four regions). For a family of four in the West (California, Washington), the VA minimum residual income for a loan amount over $80,000 is $1,117/month. If the veteran’s residual income exceeds this minimum by 20% or more ($1,340/month), the DTI ratio becomes secondary in the underwriting decision.

This residual income approach is why VA loans regularly approve refinances at 50%, 55%, and even 60% DTI. A veteran earning $9,000/month net with a $4,500 mortgage payment and $1,500 in other debts has a 67% gross DTI but may have $1,500+ in monthly residual income after accounting for maintenance, utilities, and the regional adjustment—well above the VA minimum. The VA recognizes that DTI alone does not determine affordability; what matters is whether the family has enough money left each month to live comfortably after all obligations are paid.

Veterans considering a streamline refinance should also review VA IRRRL streamline refinance guidelines, which offer reduced documentation requirements that can simplify the process for high-DTI borrowers with existing VA loans.

Case Study: VA Residual Income Saved a 58% DTI Refinance

A retired Navy officer in San Diego (serving CA and WA clients) contacted me after two conventional lender denials for a cash-out refinance. His DTI was 58% due to his military pension, VA disability payments, and his wife’s part-time income being offset by student loan obligations and two car payments. Both conventional lenders rejected the file because 58% exceeded their 50% DTI overlay. I restructured the analysis as a VA cash-out refinance. His VA disability income is tax-free, which the VA allows to be “grossed up” by 25% for qualification purposes. After the gross-up adjustment, his residual income was $1,680/month—51% above the VA minimum for his family size and region. The VA underwriter approved the loan without any conditions related to DTI. The entire file closed in 32 days. — Mo Abdel, NMLS #1426884

Debt Payoff and Restructuring Strategies to Lower Your DTI Before Refinancing

When compensating factors alone are not sufficient to qualify at your current DTI, strategically reducing your DTI through targeted debt payoff or restructuring can bridge the gap between denial and approval. The key is identifying which actions produce the largest DTI reduction per dollar spent.

Strategic Debt Elimination for Maximum DTI Impact

Not all debt elimination is equal when it comes to DTI impact. A $15,000 car loan with a $450/month payment reduces DTI by $450 divided by your gross monthly income. For a $10,000/month earner, that is a 4.5 percentage point DTI reduction. A $15,000 student loan with a $175/month income-driven payment only reduces DTI by 1.75 percentage points. The most efficient strategy is paying off debts with the highest monthly payment relative to their balance:

Credit cards with high minimum payments: Paying the balance to zero eliminates the minimum payment from DTI. A $5,000 credit card with a $150/month minimum gives 3x more DTI reduction per dollar than a $15,000 student loan with a $150/month payment.
Car loans with fewer than 10 months remaining: If a car loan has 10 or fewer payments left, most conventional and FHA lenders exclude it from DTI. Paying off 2–3 extra payments to reach that threshold eliminates the entire payment from your DTI without paying off the full balance.
Personal loans and installment debts: These often carry high monthly payments relative to balances and produce significant DTI reduction when eliminated.

Co-Borrower Addition to Increase Qualifying Income

Adding a co-borrower (spouse, partner, or qualifying family member) can reduce DTI by increasing the income denominator of the ratio. If your solo DTI is 52% ($5,200 in debts / $10,000 income) and a co-borrower adds $4,000/month in income with $300/month in debts, the combined DTI drops to 39.3% ($5,500 / $14,000). This strategy works best when the co-borrower has high income and low debts. Be aware that adding a co-borrower also adds their debts to the DTI calculation and both credit scores are evaluated for pricing.

For self-employed borrowers whose tax return income understates their actual earnings, bank statement loan programs calculate income from actual deposits, which often produces a lower DTI than tax return-based calculations.

Non-QM Refinance Options for Borrowers Exceeding Standard DTI Limits

When DTI exceeds the limits of conventional, FHA, and VA programs even after compensating factors and debt restructuring, Non-QM (non-qualified mortgage) programs provide alternative refinancing pathways. These programs use different income calculation methods that can produce significantly different DTI figures for the same borrower.

Bank Statement Loans: Alternative Income Calculation

Bank statement loan programs qualify borrowers based on 12–24 months of bank deposits rather than tax return income. This approach is particularly valuable for self-employed borrowers and commission earners whose taxable income (after business deductions) produces a high DTI, but whose actual cash flow is strong. A self-employed contractor with $200,000 in annual bank deposits but only $110,000 in net tax return income qualifies at a dramatically different DTI under a bank statement program versus a conventional program. Bank statement programs offered through wholesale lenders typically cap DTI at 43–50%.

DSCR Loans for Investment Property Refinances

For investment property refinances, DSCR (Debt Service Coverage Ratio) loans bypass personal DTI entirely. DSCR loans qualify based on the property’s rental income relative to the proposed mortgage payment. A property with $3,000/month in rental income and a $2,400/month proposed payment has a 1.25 DSCR—qualifying at most DSCR lenders regardless of the borrower’s personal DTI. This makes DSCR the go-to program for real estate investors with high personal DTI who need to refinance rental properties.

Asset Depletion Programs

Asset depletion programs calculate qualifying income by dividing the borrower’s liquid assets by a set number of months (typically 360 for a 30-year term or 240 for reduced term). A borrower with $1,000,000 in liquid assets qualifies for approximately $2,778/month in calculated income ($1,000,000 / 360), which is added to any other documented income for DTI calculation purposes. Asset depletion is particularly useful for retirees with substantial savings but limited monthly income.

Why I Run Every High DTI File Through Multiple Programs

When a client comes to me with a DTI above 45%, I run the file through at least three different pathways before making a recommendation. I submit through Fannie Mae DU at a lender with no DTI overlay to see if the automated system approves. I evaluate FHA eligibility including potential streamline options. If the client is a veteran, I calculate VA residual income. And I assess whether a bank statement or Non-QM program produces a more favorable DTI using alternative income documentation. In approximately 40% of my high-DTI files, the program that produces the best outcome is not the program the borrower initially applied for. A borrower who applied for a conventional refinance and was denied may ultimately close an FHA refinance at a lower rate, or a VA cash-out refinance with more proceeds. The point is not just finding one approval—it is finding the best approval from 200+ lenders across multiple programs. — Mo Abdel, NMLS #1426884

Extended FAQ: Refinancing with High Debt-to-Income Ratio

What is the maximum DTI ratio to refinance a mortgage in 2026?

Maximum DTI for refinancing depends on the loan program and underwriting method. Fannie Mae conventional loans allow up to 50% DTI with Desktop Underwriter (DU) approval and strong compensating factors. FHA permits up to 56.99% DTI with automated underwriting approval and compensating factors, though manual underwriting caps at 40% front-end and 50% back-end. VA loans have no hard DTI cap but use residual income as the primary qualification measure, with most lenders approving DTI ratios up to 60% when residual income requirements are met. Non-QM programs typically cap at 43-50% DTI depending on the lender.

What are compensating factors for a high DTI mortgage refinance?

Compensating factors are strengths in your loan file that offset the risk of a high debt-to-income ratio. The most impactful compensating factors include: significant cash reserves (3-6+ months of mortgage payments), a high credit score (720 or above), substantial home equity (low loan-to-value ratio below 75%), a long and stable employment history (2+ years at the same employer), documented history of making housing payments on time despite the high DTI, and minimal payment shock (the new payment is similar to or lower than the current payment). Each loan program weighs compensating factors differently.

Can I refinance with a 50% DTI ratio?

Yes, refinancing with a 50% DTI is achievable through multiple loan programs. Fannie Mae Desktop Underwriter frequently approves loans at 50% DTI when the borrower has strong credit, adequate reserves, and low LTV. FHA automated underwriting approves DTI ratios up to 56.99% with compensating factors. VA loans approve DTI above 50% routinely when residual income requirements are met. The key is matching your loan file to the program and lender whose DTI policies accommodate your specific ratio, which a wholesale broker comparing 200+ lenders accomplishes efficiently.

What is the difference between front-end and back-end DTI for refinancing?

Front-end DTI (also called housing ratio) measures only your housing costs divided by gross monthly income. Housing costs include principal, interest, taxes, insurance, HOA dues, and any mortgage insurance. Back-end DTI (total DTI) includes housing costs plus all other monthly debt obligations: car payments, student loans, credit card minimum payments, personal loans, child support, and alimony. Most refinance programs focus primarily on back-end DTI. FHA is one of the few programs with specific front-end DTI limits (31% for manual underwriting), though automated underwriting can exceed this threshold.

Does paying off debt before refinancing lower my DTI enough to qualify?

Paying off debt reduces your DTI, but the impact depends on which debts you eliminate. Paying off a $400/month car payment reduces your DTI by $400 divided by your gross monthly income. For a borrower earning $8,000/month, eliminating that car payment reduces DTI by 5 percentage points. The most effective strategy is eliminating debts with the highest monthly payments relative to their balances. Credit card minimum payments, car loans, and student loans with high monthly obligations provide the largest DTI reduction per dollar spent. Your mortgage broker can calculate exactly how much each debt payoff changes your DTI.

How does Fannie Mae Desktop Underwriter handle high DTI applications?

Fannie Mae Desktop Underwriter (DU) uses a comprehensive risk assessment algorithm that evaluates your entire loan file, not just DTI in isolation. DU can approve loans with DTI ratios up to 50% when other risk factors are favorable: strong credit scores, low LTV, substantial reserves, stable employment, and clean payment history. DU weighs all factors together and issues an Approve/Eligible finding when the overall risk profile is acceptable. If DU issues a Refer finding due to high DTI, the loan cannot be approved as a conventional loan and must either be restructured or submitted through a different program like FHA or Non-QM.

What is VA residual income and how does it help with high DTI refinances?

VA residual income is the amount of money left over each month after paying all major expenses including the mortgage, taxes, insurance, debts, and estimated utilities and maintenance. The VA publishes minimum residual income tables based on family size and geographic region. Veterans whose residual income exceeds the VA minimum by 20% or more can qualify for refinancing even with DTI ratios above 50-60%. This makes VA loans the most flexible option for eligible veterans with high monthly obligations relative to income, because the VA focuses on whether you can actually afford the payment, not just the mathematical ratio.

Can I add a co-borrower to reduce my DTI for a refinance?

Adding a co-borrower (spouse, partner, or family member) can increase qualifying income and lower the DTI ratio if the co-borrower has verifiable income and acceptable credit. The co-borrower must be on the loan and typically on the title. Adding a co-borrower combines both incomes for qualification but also adds both parties debt obligations to the DTI calculation. This strategy works best when the co-borrower has significant income with minimal debts. Note that both borrowers credit scores are evaluated, and many lenders use the lower of the two middle scores for pricing purposes.

What Non-QM refinance options exist for high DTI borrowers?

Non-QM (non-qualified mortgage) programs offer refinance options for borrowers whose DTI exceeds conventional and government program limits. Bank statement loans qualify based on actual bank deposits rather than tax return income, which can produce a lower effective DTI for self-employed borrowers. DSCR (debt service coverage ratio) loans for investment property refinances qualify based on property cash flow rather than personal DTI. Asset depletion programs calculate qualifying income from liquid assets rather than employment income. Each Non-QM program has its own DTI guidelines, typically capping at 43-50%, with some programs offering higher limits with compensating factors.

How does an FHA streamline refinance handle DTI differently than a standard FHA refinance?

An FHA streamline refinance does not require full income documentation or DTI calculation when the borrower meets specific criteria: the refinance results in a net tangible benefit (lower payment or move from ARM to fixed), the borrower has been current on the existing FHA loan for the past 12 months, and the borrower has made at least 6 payments on the current loan. This makes FHA streamline refinancing a powerful option for high DTI borrowers who already have an FHA loan, because the DTI limitation that might prevent a standard refinance does not apply to the streamline process.

Should I consolidate debt through a cash-out refinance to lower my DTI?

A cash-out refinance to consolidate debt can lower your monthly DTI by replacing multiple high-payment debts with a single lower mortgage payment spread over 30 years. However, this strategy converts unsecured debt (credit cards, personal loans) into debt secured by your home, which carries different risk. The math works when the monthly payment reduction is significant and you have the discipline not to accumulate new debt. A wholesale broker can model the exact DTI impact of a debt consolidation refinance across multiple lenders and determine whether the lower monthly payment justifies the higher loan balance and closing costs.

What debts are excluded from DTI calculation when refinancing?

Several debt types can be excluded from DTI calculation under specific circumstances. Debts with 10 or fewer remaining payments can be excluded by most conventional and FHA lenders. Debts paid by someone else (with 12 months of documented proof) can be excluded. Business debts that are obligations of the business entity (not the individual) documented on business tax returns can sometimes be excluded. Deferred student loans are included in DTI at 0.5% of the outstanding balance for conventional loans or 1% for FHA. Understanding exclusion rules is critical for high DTI borrowers because removing even one debt from the calculation can change an approval outcome.

How does a wholesale mortgage broker help borrowers with high DTI refinance?

A wholesale mortgage broker comparing 200+ lenders identifies which institutions have the most favorable DTI limits, compensating factor policies, and debt exclusion rules for your specific financial profile. DTI limits vary significantly across lenders: one lender may cap at 45% DTI while another approves up to 50% with the same Fannie Mae DU findings. Lender overlays on compensating factors also differ, with some requiring 3 months of reserves while others accept 2 months. The broker structures your file to maximize qualification by selecting the lender whose policies best accommodate your DTI level and compensating factors.

Expert Summary: Refinancing with a High DTI Ratio

A high debt-to-income ratio does not disqualify you from refinancing—it requires strategic program selection, strong compensating factors, and the right lender. The 43% DTI threshold that many borrowers assume is the universal limit is actually a lender overlay at institutions that add restrictions beyond agency guidelines. Fannie Mae DU approves conventional refinances at 50% DTI, FHA automated underwriting extends to 56.99%, and VA loans have no hard DTI cap when residual income supports the payment.

The most effective approach to a high-DTI refinance combines three strategies: identifying and documenting compensating factors (reserves, credit score, low LTV, payment history), strategically reducing DTI through targeted debt payoff when possible (prioritizing debts with the highest monthly payment relative to balance), and selecting the lender whose DTI overlay policies and compensating factor requirements produce the most favorable outcome for your specific financial profile.

For homeowners with equity who want to reduce monthly obligations, a cash-out refinance for debt consolidation can replace multiple high-payment debts with a single lower mortgage payment, while seniors 62+ may want to explore a DSCR loan for investment property refinances that bypass personal DTI entirely.
