Understanding Home Equity

Home equity is the difference between your home's current market value and what you owe on your mortgage. It grows as you make mortgage payments (reducing the balance) and as your home appreciates in value. You can access this equity through a HELOC (Home Equity Line of Credit) or a home equity loan.

HELOC vs Home Equity Loan

HELOC: A revolving line of credit (like a credit card secured by your home). Draw funds as needed during the "draw period" (typically 10 years), paying interest only on what you use. After the draw period, you repay principal + interest over the remaining term. Rates are usually variable.

Home Equity Loan: A lump sum loan with fixed payments and a fixed rate. You receive all the money upfront and repay over a set term (5-20 years). Better if you know exactly how much you need and want payment predictability.

Tax Deductibility

Interest on home equity loans and HELOCs is tax-deductible if the funds are used to "buy, build, or substantially improve" the home securing the loan. Interest is NOT deductible if used for other purposes (debt consolidation, car purchase, etc.).

Risks to Consider

Your home is the collateral. If you can't make payments, you could face foreclosure. Don't borrow against your equity for wants (vacations, consumer purchases). Common smart uses include home improvements (which add value), major repairs, and education funding. Check your overall debt picture with our Debt-to-Income Calculator.

Frequently Asked Questions

How much equity do I have?
Equity = Home Value − Mortgage Balance. If your home is worth $450,000 and you owe $280,000, you have $170,000 in equity (37.8%). Lenders typically allow borrowing up to 80-85% of your home's value minus your mortgage balance.
What's the difference between a HELOC and home equity loan?
A HELOC is a revolving line of credit with variable rates — you draw money as needed. A home equity loan is a lump sum with a fixed rate and fixed payments. Choose a HELOC for ongoing needs, a loan for one-time expenses.
Is home equity loan interest tax deductible?
Only if the funds are used to buy, build, or substantially improve the home. Interest on funds used for other purposes (debt consolidation, etc.) is not deductible under current tax law.
How does a HELOC affect my mortgage?
A HELOC is a second lien on your property, separate from your first mortgage. You keep your existing mortgage and add the HELOC. If you sell, the mortgage is paid first, then the HELOC, from the sale proceeds.
