Should You Get a HELOC in Washington?
HELOCs make sense in Washington when: (1) you have at least 15-20% equity in your home, (2) you need flexible access to cash for renovations, education, or business expenses, (3) you can stomach a variable rate that adjusts with Prime, and (4) you don't want to refinance your low-rate first mortgage.
HELOC vs cash-out refinance
If your existing mortgage rate is below current market rates (typical for anyone who locked before 2022), a HELOC almost always beats a cash-out refi. You preserve your low first-mortgage rate and only pay HELOC rates on the borrowed portion. If your existing rate is at or above current rates, run the math both ways.
Qualifying for a HELOC in Washington
Most Washington lenders require: FICO score 680+ (720+ for the best rates), debt-to-income ratio under 43%, combined loan-to-value under 85% (), proof of income (W-2 or tax returns), and a current home appraisal. The full process takes 2-6 weeks.
Tax deductibility
Under current IRS rules (2017 TCJA, in effect through 2025), HELOC interest is only tax-deductible if the borrowed funds are used to "buy, build, or substantially improve" the home securing the loan. Using HELOC funds for debt consolidation, vacations, or business expenses makes the interest non-deductible.
