HELOC: Flexible Line of Credit
A home equity line of credit (HELOC) is revolving credit secured by your home—you draw as needed and pay interest on the balance. Often faster than a home equity loan, with no big loan commitment upfront. Best when you need flexibility.

HELOC Highlights
A line of credit backed by your home equity. Draw when you need it, pay interest on what you use. Often the fastest way to tap equity.
Revolving line
Draw as needed, pay interest only on the balance. No big loan commitment upfront—you control when and how much to borrow.
Variable rate
Most HELOCs tie to prime or another benchmark. Rates can move with the market. Some lenders offer fixed-rate options for drawn amounts.
Second lien
Your first mortgage stays in place. A HELOC adds a separate line of credit secured by your home equity.
Often no full appraisal
Many HELOCs use automated valuations—faster approval, often 2–4 weeks. Compare with home equity loans (3–5 weeks) and cash-out refi (30–45 days).
How draws and payback work
A HELOC isn't one big loan check—it's a line you tap over time. Below is a simplified timeline. Dollar amounts are examples only.
- 1
First draw
You advance $15,000 from your line.
Interest starts accruing on what you actually borrowed—not your full credit limit. On a typical variable HELOC, the rate in effect when you draw is tied to the lender's index (often prime plus a margin) and can change over time. Your lender will bill a minimum payment on a schedule (usually monthly) based on your balance and terms—not a separate due date per small draw.
- 2
Another draw
A few months later you take $10,000 more.
Your outstanding balance is now $25,000. Most HELOCs charge one variable rate on the total balance; if the index moves, your rate (and minimum payment) can change. Some lenders offer optional fixed-rate advances that lock a segment—terms vary by lender.
- 3
Pay down part of the balance
You pay $5,000 toward principal.
During the draw period, principal you pay back usually becomes available to borrow again (revolving). Less principal outstanding means less interest accruing going forward—not a separate fee for how long you kept the money.
- 4
Keep using or wind down
Draw period ends → repayment phase.
After the draw period, you often can't take new advances and you'll pay principal plus interest on what's left until the line is paid off—exact structure is in your loan agreement.
Why a HELOC Works
When you need flexibility—ongoing projects, variable costs, or uncertain timing—a HELOC gives you a line you control without committing to one large loan upfront.
Flexibility
Draw when you need it—no new application each time.
Pay interest only on what you use
Interest on the balance drawn, not the full credit line.
Faster and simpler
Often no full appraisal—quickest way to tap equity.
HELOC At a Glance
Rates & terms
Most HELOCs have variable rates tied to prime. Draw period often 10 years; repayment period 10–20 years. Interest-only during draw in many cases.
HELOC guide →How much can you borrow?
Lenders typically allow 80–90% of home value minus your first mortgage. Combined loan-to-value (CLTV) limits vary by lender.
Your income, credit, and debt-to-income also affect your limit.
HELOC vs alternatives
Prefer a lump sum and fixed payments? A home equity loan may fit. Want a new first loan larger than your current loan balance and cash at closing? See cash-out refinance.

Variable rates, draws, and bank loan prime rate
Most HELOCs have a variable rate: what you pay can go up or down over the life of the line. In practice, lenders often tie that rate to an index—very commonly the bank prime rate—plus a margin spelled out in your agreement. If your deal isn't literally "prime + X%," the same idea often applies: your rate still tends to move when that benchmark moves.
Because a HELOC is a line you draw over time, each time you take money, the rate in effect for that balance is usually based on the index and terms at that point (subject to your contract and any rate floors or caps). So prime isn't just background noise—it's often the main lever for how expensive each draw is when the index changes.
