Construction-to-Permanent Loans Through a Wholesale Mortgage Broker: One-Time Close Guide [2026]
According to Mo Abdel, licensed mortgage broker (NMLS #1426884) with Lumin Lending:
"Construction-to-permanent one-time close loans eliminate the need for two separate closings, saving borrowers thousands in duplicate fees. The challenge is finding them — most retail banks either don't offer construction-to-permanent products or restrict them to cookie-cutter builds. Through our wholesale channel with 200+ lenders, we access construction programs from specialty lenders and regional banks that finance custom homes, ADUs, and even investor build-to-rent projects in California and Washington. The wholesale advantage for construction lending is more significant than any other loan type because the product variation between lenders is enormous."

What Is a Construction-to-Permanent Loan and How Does the Wholesale Channel Access It?
A construction-to-permanent (CTP) loan is a single financing product that covers both the construction phase and the permanent mortgage. Instead of obtaining a separate construction loan and then refinancing into a permanent mortgage upon completion, a CTP loan handles everything in one transaction. The borrower closes once, pays one set of closing costs, and locks their permanent rate upfront.
During the construction phase, the lender releases funds to the builder in stages called "draws" as work milestones are completed. The borrower makes interest-only payments on the amount that has been drawn — not the full loan amount. Once the certificate of occupancy is issued and the final inspection is complete, the loan automatically converts to a permanent mortgage with full principal and interest payments.
The wholesale channel is particularly valuable for construction-to-permanent loans because product availability varies dramatically between lenders. Retail banks typically offer a single CTP product with rigid builder requirements and limited property types. Through our network of 200+ wholesale lenders, we access CTP programs from regional banks, community lenders, and specialty construction finance companies — each with different draw schedules, builder qualification criteria, maximum construction periods, and property type allowances.
In my experience originating construction-to-permanent loans across California and Washington, the single biggest advantage the wholesale channel provides is builder flexibility. I have worked with borrowers whose builder was declined by three retail banks before we found a wholesale lender that approved the project based on the builder's track record and financial strength rather than checking a box on a rigid approval list.
Construction-to-Permanent Loan Draw Schedule: How Funds Are Released
| Draw # | Construction Phase | Typical % Released | Verification Required |
|---|---|---|---|
| Draw 1 | Foundation & Site Work | 15-20% | Permits pulled, foundation poured and inspected |
| Draw 2 | Framing & Roof | 20-25% | Framing complete, roof installed, framing inspection passed |
| Draw 3 | Mechanical Systems | 15-20% | Plumbing, electrical, HVAC rough-in inspected |
| Draw 4 | Interior Finish | 20-25% | Drywall, flooring, cabinets, fixtures installed |
| Draw 5 | Final Completion | 10-15% | Final inspection, certificate of occupancy, landscaping |
| Holdback | Retention Reserve | 5-10% | Released after final punch list completion and lien waivers |
Documentation Requirements for Construction-to-Permanent Loans Through a Wholesale Broker
Construction-to-permanent loans require significantly more documentation than standard purchase mortgages. In addition to traditional income, asset, and credit documentation, borrowers and builders must submit construction-specific paperwork. Here is the complete documentation checklist I provide to every construction loan borrower in my California and Washington pipeline:
Complete Construction-to-Permanent Loan Documentation Checklist
- 1Standard mortgage application and credit authorization. Same as any mortgage — complete 1003 application, two years of tax returns, two months of bank statements, 30 days of pay stubs.
- 2Executed construction contract between borrower and builder. Must include total cost breakdown, construction timeline, payment schedule, change order procedures, and warranty terms.
- 3Complete architectural plans and specifications. Full blueprint set including floor plans, elevations, structural engineering, and material specifications approved by the local building department.
- 4Building permits from the local jurisdiction. Proof that all required permits have been obtained or will be obtained prior to construction commencement.
- 5Builder documentation package. General contractor license, liability insurance ($1M+ typical), workers compensation insurance, financial statements, and references from 3-5 completed projects.
- 6Detailed cost breakdown by trade. Line-item budget covering site preparation, foundation, framing, roofing, plumbing, electrical, HVAC, insulation, drywall, finishes, landscaping, and contingency reserve.
- 7Lot purchase documentation or proof of ownership. If the lot is being purchased as part of the CTP loan, the purchase agreement is required. If already owned, a deed and current title report.
- 8Appraisal based on plans and specifications. The appraiser values the home based on the completed project using comparable new construction sales in the area.
How Do Builder Requirements Differ Between Wholesale Construction-to-Permanent Lenders?
Builder requirements represent the area where wholesale access provides the most significant advantage for construction-to-permanent borrowers. I have seen firsthand how dramatically lender requirements vary — and how a borrower's dream home project can hinge on finding the right lender-builder match.
Some wholesale lenders maintain pre-approved builder lists and require your contractor to apply for approval before the loan can proceed. Others evaluate builders on a case-by-case basis, reviewing their license, insurance, financial capacity, and project history. The case-by-case approach tends to be more favorable for borrowers working with smaller custom builders or contractors who specialize in specific geographic areas.
In California, where the Contractors State License Board (CSLB) maintains rigorous licensing requirements, many wholesale lenders rely on the CSLB verification as a primary qualification measure. Washington State requires contractor registration through the Department of Labor & Industries, and wholesale lenders in that state similarly use registration verification as a baseline for builder approval.
The critical difference is this: when you work with a retail bank that rejects your builder, your only option is to find a new builder or a new bank. When you work with a wholesale broker, we simply submit to a different lender in our network that has builder qualification criteria your contractor can meet. I have placed dozens of construction-to-permanent loans where the builder was rejected by the borrower's initial bank choice, and we found a wholesale lender that approved both the borrower and the builder within the same week.
Construction-to-Permanent Loan Options: Custom Homes, Spec Homes, Renovations, and ADUs
The construction-to-permanent loan structure is not limited to ground-up custom home construction. Through wholesale channels, borrowers access CTP products for multiple project types. The available options through our 200+ lender network include:
| Project Type | CTP Availability | Key Requirements | Wholesale Advantage |
|---|---|---|---|
| Custom Home Build | Widely available | Full plans, licensed builder, permits | Builder flexibility — more lenders accept more builders |
| Spec Home (Builder) | Common | Builder-owned lot, plans approved | Competitive pricing through lender shopping |
| Major Renovation | Select lenders | Renovation plans, contractor, scope of work | Access to renovation-specific CTP products (FHA 203k alternative) |
| ADU Construction (CA) | Growing availability | ADU plans, permits, existing property equity | Specialty ADU lenders available only through wholesale |
| Build-to-Rent (DSCR) | Specialty lenders | Projected rental income, investor experience | DSCR construction products not available at retail banks |
| Teardown & Rebuild | Limited lenders | Demolition plan, environmental clearance, new construction plans | Niche lenders specialize in teardown-to-new construction |
DSCR Construction-to-Permanent Loans for Investors: Building Rental Properties Through Wholesale
One of the most compelling construction-to-permanent products available through the wholesale channel is the DSCR construction-to-permanent loan. This product allows real estate investors to finance the construction of rental properties — and convert to a permanent DSCR mortgage — without providing traditional income documentation.
In traditional construction lending, investors face a catch-22: construction loans require personal income verification, but investors often rely on rental income and business revenue that does not translate cleanly to conventional underwriting. DSCR construction-to-permanent loans solve this by qualifying the project based on the projected debt service coverage ratio of the completed property.
From my work with California and Washington investors, DSCR construction-to-permanent loans are particularly popular for build-to-rent single-family homes and small multifamily projects (2-4 units). The typical structure provides interest-only construction financing for 12-18 months, then converts to a 30-year DSCR permanent loan with no income documentation required. The projected rental income of the completed property must support a DSCR of 1.0 or higher, depending on the lender.
These programs are exclusively available through wholesale channels. Retail banks do not offer DSCR construction products because the secondary market for these loans is limited to private capital and non-QM investors. Our wholesale network includes multiple lenders that specialize in DSCR construction financing, and each has different requirements for investor experience, minimum DSCR ratios, maximum loan amounts, and geographic coverage.
How Do Lot Loans Fit Into the Construction-to-Permanent Process?
Land acquisition is often the first step in a new construction project, and how you handle lot financing affects your construction-to-permanent options. There are three primary scenarios I encounter in my California and Washington construction lending practice:
3 Lot Scenarios in Construction-to-Permanent Lending
- 1Lot included in CTP loan. Many one-time close programs allow you to purchase the lot and finance construction in a single transaction. The lot purchase closes simultaneously with the construction loan origination. This is the simplest path and avoids separate lot financing.
- 2Lot already owned free and clear. If you own the land outright, its appraised value typically counts as part of your down payment or equity position. This can reduce or eliminate the cash down payment requirement for the construction-to-permanent loan.
- 3Lot purchased with existing lot loan. If you financed the lot purchase separately, the existing lot loan balance is paid off through the construction-to-permanent loan proceeds at closing. The lot equity above the payoff amount counts toward your equity position.
FHA, VA, and Conventional Construction-to-Permanent Loan Options Available Through Wholesale
The wholesale channel provides access to construction-to-permanent products across all major loan categories. Each program type serves different borrower profiles, and having access to all of them through a single broker relationship means borrowers receive the program that truly fits — not the one a single bank happens to offer.
Conventional Construction-to-Permanent Loans
Conventional CTP loans follow Fannie Mae or Freddie Mac guidelines with construction-specific overlays. Typical requirements include 680+ credit score, 10-20% down payment (depending on lender and property type), and a construction period of up to 12 months. Some wholesale lenders extend construction periods to 18 months for complex builds. Conventional CTP loans are available for primary residences, second homes, and in limited cases, investment properties.
FHA One-Time Close Construction Loans
FHA one-time close construction loans are available with as little as 3.5% down payment and credit scores as low as 620 through select wholesale lenders. These government-backed construction loans include FHA mortgage insurance and follow FHA property standards. The FHA one-time close is particularly valuable for first-time homebuyers who want to build rather than buy existing inventory. Construction periods of up to 12 months are standard.
VA Construction-to-Permanent Loans
Eligible veterans and active-duty service members can access VA construction-to-permanent loans with zero down payment. VA construction loans are available through select wholesale lenders, and the one-time close structure means veterans close once and convert to a permanent VA loan upon completion. The VA funding fee applies but can be financed into the loan. In my experience, VA construction loan availability has expanded significantly in the wholesale channel over the past two years, with more lenders entering this space.
ADU Construction-to-Permanent Loans in California and Washington: Wholesale Access
California's aggressive ADU legislation has created enormous demand for construction financing options tailored to accessory dwelling units. Since 2020, California has streamlined ADU permitting, eliminated many setback requirements, and allowed homeowners to build both attached and detached ADUs on most residential lots. Washington State has followed with similar ADU-friendly legislation in multiple jurisdictions.
Through wholesale channels, homeowners in California and Washington access construction-to-permanent loans specifically designed for ADU projects. These programs differ from standard CTP loans in several important ways: they use the existing property's equity as the primary collateral, they account for the added value of the completed ADU in the post-construction appraisal, and many allow the projected ADU rental income to qualify for the loan.
I have originated ADU construction loans for California homeowners building everything from 400 square foot studio units to 1,200 square foot two-bedroom detached ADUs. The cost range varies dramatically by region — from roughly $150,000 to $400,000+ in high-cost coastal markets — and having 200+ lenders means we find CTP programs that match each project's specific scope and budget.
Construction-to-Permanent Loan Data Hub: Key Metrics by Program Type
| Program | Min. Down Payment | Min. Credit Score | Max Construction Period | Occupancy Types |
|---|---|---|---|---|
| Conventional CTP | 10-20% | 680+ | 12-18 months | Primary, second home |
| FHA One-Time Close | 3.5% | 620+ | 12 months | Primary only |
| VA Construction | 0% | 620+ | 12 months | Primary only |
| DSCR Construction | 20-25% | 660+ | 12-18 months | Investment only |
| ADU Construction (CA/WA) | Existing equity based | 680+ | 12 months | Owner-occupied property |
| Jumbo CTP | 20-30% | 700+ | 12-24 months | Primary, second home |
People Also Ask: Construction-to-Permanent Loan Wholesale Questions
How long does a construction-to-permanent loan take to close?
Construction-to-permanent loans typically take 45-60 days to close from application to initial closing, longer than standard purchase mortgages due to builder approval and plans review. The construction phase then runs 12-18 months before the loan converts to permanent financing. Working with a wholesale broker who has pre-established lender relationships can reduce the initial closing timeline.
Can I be my own builder with a construction-to-permanent loan?
Owner-builder construction-to-permanent loans exist but are limited to a small number of wholesale lenders with strict qualification requirements. Most lenders require the owner-builder to hold a valid general contractor license, demonstrate construction experience, and provide detailed project management plans. Through wholesale access, we find lenders that allow qualified owner-builders.
What happens if my builder goes bankrupt during construction?
Builder default is one of the most significant risks in construction lending, and the draw schedule structure is specifically designed to mitigate this risk. Funds are released only after verified completion of each phase. Most CTP lenders require builders to carry performance bonds or provide financial statements demonstrating stability.
Is a construction-to-permanent loan more expensive than buying an existing home?
Construction-to-permanent loans carry slightly higher rates than standard purchase mortgages because lenders assume additional construction risk during the build phase. However, the one-time close structure significantly reduces total costs compared to financing construction and permanent mortgage separately. Wholesale access provides more competitive pricing across multiple lenders.
Do construction-to-permanent loans require larger down payments?
Down payment requirements vary by program: conventional CTP loans require 10-20%, FHA one-time close requires 3.5%, and VA construction requires 0% for eligible veterans. DSCR construction loans for investors typically require 20-25%. Through wholesale channels, borrowers access the full range of down payment options rather than being limited to a single bank's requirements.
Can I use a construction-to-permanent loan for a modular or manufactured home?
Select wholesale lenders offer construction-to-permanent financing for modular homes that are built to local building codes and permanently affixed to a foundation. Manufactured homes on permanent foundations may also qualify through specific lender programs. Product availability varies significantly between lenders, making wholesale access essential for these property types.
How does the appraisal work for a home that does not exist yet?
Construction-to-permanent appraisals use a "subject to completion" methodology, valuing the home based on architectural plans, specifications, and comparable new construction sales in the area. The appraiser projects the completed home's market value using the planned square footage, finishes, and features compared to recently sold new construction.
What are construction loan interest reserve funds?
Interest reserve funds are built into the construction loan to cover interest-only payments during the build phase, so borrowers do not make out-of-pocket payments during construction. The reserve amount is calculated based on the estimated construction timeline and anticipated draw schedule. Not all lenders offer interest reserves — wholesale access helps identify those that do.
Frequently Asked Questions: Construction-to-Permanent Loans Through Wholesale
What is a construction-to-permanent loan?
A construction-to-permanent loan combines your construction financing and permanent mortgage into a single loan with one closing. During construction, you make interest-only payments on funds drawn. Once the home is complete, the loan automatically converts to a standard mortgage with principal and interest payments.
What is the difference between one-time close and two-time close construction loans?
A one-time close (OTC) construction loan has a single application, single closing, and single set of closing costs. A two-time close requires separate construction and permanent loans with two applications, two closings, and two sets of closing costs. The one-time close saves borrowers thousands in duplicate fees and eliminates requalification risk.
Why use a wholesale mortgage broker for a construction-to-permanent loan?
Wholesale brokers access construction-to-permanent products from specialty lenders, regional banks, and credit unions that do not offer these programs directly to consumers. With 200+ lender relationships, brokers match your project to lenders with the right combination of rates, terms, draw schedules, and builder requirements for your specific situation.
What credit score do I need for a construction-to-permanent loan?
Credit score requirements vary by loan type and lender. Conventional construction-to-permanent loans typically require a 680+ score. FHA one-time close programs accept scores as low as 620. VA construction loans also accept 620+ in many cases. A wholesale broker shops across multiple lenders to find programs matching your credit profile.
How does the draw schedule work during construction?
The draw schedule releases construction funds in phases as work is completed. Typical phases include foundation, framing, mechanical (plumbing/electrical/HVAC), interior finish, and final completion. A licensed inspector verifies work completion before each draw is released to the builder. You pay interest only on the amount drawn.
Can I use a construction-to-permanent loan to build an ADU in California?
Yes. California homeowners can use construction-to-permanent loans to finance ADU (Accessory Dwelling Unit) construction. Some wholesale lenders offer specific ADU construction programs that allow you to build a detached or attached ADU on your existing property with a single-close loan that converts to a permanent mortgage upon completion.
Do I need to own the land before getting a construction-to-permanent loan?
Not necessarily. Many one-time close programs allow you to purchase the lot and finance construction in the same loan. If you already own the land, its equity can count toward your down payment. A wholesale broker identifies lenders that handle lot acquisition within the construction-to-permanent structure.
What builder requirements exist for construction-to-permanent loans?
Lenders require builders to be licensed, insured, and experienced. Documentation typically includes the builder general contractor license, liability and workers compensation insurance, references from completed projects, a detailed construction contract, and blueprints with specifications. Requirements vary by lender, which is why wholesale access matters.
Are DSCR construction-to-permanent loans available for investors?
Yes. Through wholesale channels, investors can access DSCR construction-to-permanent loans that qualify based on projected rental income rather than personal income. These build-to-rent programs finance construction and convert to permanent DSCR loans, allowing investors to build rental properties without traditional income documentation.
Can I get an FHA or VA construction-to-permanent loan through a wholesale broker?
Yes. FHA one-time close construction loans and VA construction-to-permanent loans are available through wholesale channels. FHA programs accept lower down payments and credit scores. VA programs offer zero down payment for eligible veterans. Wholesale brokers access lenders that specialize in government-backed construction products.
What happens if construction takes longer than expected?
Most construction-to-permanent loans include a construction period of 12-18 months. If construction extends beyond the agreed timeline, your broker can work with the lender on extension options. Some lenders charge extension fees while others build buffer time into the original lock period. Wholesale access provides more flexibility to find favorable extension terms.
What states does Mo Abdel offer construction-to-permanent loans in?
Mo Abdel is licensed to originate construction-to-permanent loans in California and Washington through Lumin Lending, NMLS #2716106. All construction loan products, including conventional, FHA, VA, and DSCR options, are available in both states.
Expert Summary: Why Wholesale Access Matters for Construction-to-Permanent Loans
Construction-to-permanent loans represent one of the most complex mortgage products available, and the wholesale channel provides advantages that are more significant here than in virtually any other loan category. Product availability, builder requirements, draw schedules, construction periods, and program types vary dramatically between lenders. A retail bank offers one CTP product with one set of rules. Through our wholesale network of 200+ lenders, we match your specific project — whether it is a custom home, ADU, renovation, or investor build-to-rent — with the right lender for your situation.
In my experience originating construction-to-permanent loans across California and Washington, the projects that succeed are the ones where the financing matches the build plan from day one. The projects that stall are the ones where borrowers discovered mid-construction that their lender's program did not fit. Wholesale access eliminates that risk by matching the right lender to the right project before the first shovel hits the ground.
