How does a HELOC draw period work in Mercer Island?
A typical HELOC has a 10-year draw period where you can access funds as needed, paying only interest on what you use. After the draw period, you enter a 20-year repayment phase with principal and interest payments. During the draw period, your available credit replenishes as you repay — similar to a credit card secured by your Mercer Island property.
Should I get a HELOC or cash-out refinance in Mercer Island?
A HELOC is ideal if you want flexible, revolving access to equity without refinancing your first mortgage — especially if your current rate is low. A cash-out refinance replaces your entire mortgage with a new, larger loan. In Mercer Island, with median values at $2,250,000, both options provide significant equity access. Mo Abdel can compare both scenarios with rates from 200+ wholesale lenders.
What credit score do I need for a HELOC in King County?
Most HELOC lenders require a minimum credit score of 680, though some wholesale lenders offer HELOCs down to 620 with compensating factors. Higher scores (720+) unlock better rates and higher CLTV allowances. With Mercer Island's property values, strong equity positions can offset marginal credit in some programs.
