Quick answer
Ada County's median sale price hit $595,000 in August 2026, up 6.9%, so many Boise-area owners have substantial equity: with $300,000 owed, roughly $205,000 at 85% combined loan-to-value. Idaho has no transfer or mortgage tax, and recording a mortgage costs $45. Because Idaho is a community property state, both spouses must sign a HELOC on community real estate. Best-borrower HELOC APRs in Idaho run about 7.40% after the September prime increase.

Idaho rules that affect your HELOC
- Community property. Neither spouse can encumber community real estate unless the other signs the mortgage (Idaho Code 32-912). Plan on both spouses signing, even if only one is borrowing.
- No transfer or mortgage tax. Idaho doesn't tax real-estate transfers or mortgages, which keeps setup costs low.
- Recording. $45 for the first 30 pages and $3 per page after that (Idaho Code 31-3205).
- Homestead. Idaho's homestead protection doesn't block a mortgage you sign voluntarily with your spouse.
- Property tax. The homeowner's exemption takes 50% off your home's taxable value, up to $125,000, for a primary residence.
Local lenders to compare
Idaho Central Credit Union offers a 10-year HELOC with interest-only draws, and CapEd Credit Union in Boise lends up to 80% CLTV. Credit unions are worth a quote for simple W-2 files. If you need more than 80%, you're self-employed, or you want to borrow against a rental or second home, compare our program's limits and income options.
Qualifying for a HELOC in Boise
Most lenders want 15–20% equity left after the line, a credit score of 620–680 or higher, and debt-to-income under 43%. Our program allows debt-to-income up to 50%, up to 90% combined loan-to-value in certain cases, and scores down to 600 with compensating factors. Self-employed borrowers can qualify on bank statements, a P&L, or 1099s, and one year of self-employment can work when cash flow is strong. We also offer fixed-rate home equity loans if you want one lump sum and a payment that never changes. For statewide rules and rates, see our Idaho HELOC guide.
