How to open a HELOC in 5 steps.
Last verified July 7, 2026The direct answer. A home equity line of credit turns equity into a revolving line at rates far below credit cards, with a draw period around ten years and repayment after. Lenders let you borrow to roughly 80 to 85 percent of home value minus your mortgage balance. The line is secured by the house itself, so the use has to deserve the lien: renovations, major planned expenses, a genuine safety valve. Size the equity, compare three lenders on rate structure and fees, clear appraisal, and write your own drawdown rules before the checkbook arrives.
Size your available equity.
Multiply your home's realistic value by 0.80 to 0.85 and subtract the mortgage balance. A $450,000 home with a $260,000 balance supports a line around $100,000 to $122,000. Lenders verify with their own appraisal, so anchor on conservative value. Most programs also want a 620-plus score, documented income, and total debt payments within about 43 percent of income.
Confirm the use justifies a lien on the house.
A HELOC converts unsecured problems into secured ones, so the purpose test comes first. Renovations, education, and consolidation of much costlier debt can clear it, with the note that consolidating cards moves that debt onto your home. Interest is tax-deductible only when proceeds buy, build, or substantially improve the home securing the line.
Compare three lenders on the whole structure.
Collect quotes from your current mortgage servicer, a credit union, and a bank or online lender. Compare the margin over prime, any intro rate and its duration, the lifetime rate cap, annual fees, closing costs, and early-closure fees. Ask each about fixed-rate lock options that let you freeze a drawn balance into a fixed loan; it is the feature you will want in a rising-rate year.
Clear appraisal and underwriting.
Expect income documents, mortgage statements, and insurance proof, plus an appraisal that many lenders now run as an automated or drive-by review. The process runs two to six weeks. Federal law adds a three-day right of rescission after closing on a primary residence, a built-in pause before the line goes live.
Set your own drawdown rules before drawing.
A HELOC's danger is its convenience, so write the rules now: what the line funds, the balance ceiling you will honor, and the payoff schedule for each draw, since interest-only minimums during the draw period leave principal untouched. Payments rise notably when the repayment period begins. Draws you amortize yourself on a schedule stay cheap; a line treated as income never does.
Five things to do this week.
- Compute equity at 80 to 85 percent of value minus the mortgage.
- Write the purpose test: what this line funds and what it never funds.
- Collect three quotes with margin, caps, and fee schedules.
- Ask every lender about fixed-rate lock conversions.
- Write the drawdown rules and the per-draw payoff schedule.
Questions readers ask most often.
HELOC or home equity loan?
The line suits staged or uncertain needs, like a phased renovation, because you draw as needed and pay interest only on what is drawn. The fixed home equity loan suits a single known amount with the certainty of one rate and one schedule. Hybrid HELOCs with fixed-rate locks cover both.
What are HELOC rates like?
Variable, priced at prime plus a margin, and typically well below credit cards and personal loans because the house secures the line. The number to respect is the lifetime cap, the rate the line can reach, and the payment at that cap is the one your budget has to survive.
Are HELOC funds taxable, and is the interest deductible?
Draws are borrowed money, never income, so no tax on the way out. Interest deducts only when proceeds buy, build, or substantially improve the home securing the line, and only for itemizers within the mortgage debt limits.
What happens if I sell the house?
The HELOC balance pays off at closing alongside the mortgage, and the line closes. Some lenders charge an early-closure fee inside the first two or three years, one of the fee lines the three-lender comparison sheet catches.
What is the real risk of a HELOC?
The collateral. Sustained missed payments can cost the house, which is why the purpose test and drawdown rules come before rate shopping. Variable rates rising is the second risk, managed by the lifetime cap check and fixed-rate locks on large draws.
