Frequently Asked Questions

πŸ“ -specific questions
What is Idaho's Homeowner's Exemption? +

Idaho exempts 50% of your home's value (up to $125,000) from property taxes for primary residences. This can save thousands annually.

What is a HELOC? +

A Home Equity Line of Credit (HELOC) is a revolving credit line secured by your home equity. Unlike a loan, you can borrow, repay, and borrow again during the draw period, paying interest only on what you use.

How does the Draw Period work? +

During the draw period (typically 10 years), you can withdraw funds and often pay interest-only. After this ends, the repayment period begins (usually 20 years), and you must pay back both principal and interest.

HELOC vs Home Equity Loan? +

A HELOC has variable rates and works like a credit card (borrow as needed). A Home Equity Loan provides a lump sum with a fixed interest rate and fixed monthly payments.

Are HELOC rates variable? +

Yes, most HELOCs have variable interest rates tied to the Prime Rate. This means your monthly payment can fluctuate over time unless you find a lender offering a fixed-rate option.

Is HELOC interest tax deductible? +

Under current law (through 2025), interest on home equity debt is tax-deductible only if the funds are used to buy, build, or substantially improve the taxpayer's home that secures the loan.
