HELOC Guide
How home equity lines of credit work — the draw period, repayment period, variable rate structure, qualification requirements, and the smartest ways to use a HELOC in 2026.
What Is a HELOC?
A home equity line of credit (HELOC) is a revolving credit line secured by your home that lets you borrow against your equity as needed, up to an approved limit. Unlike a home equity loan (which gives you a lump sum), a HELOC works more like a credit card — you draw funds when you need them, repay what you used, and draw again during the draw period.
HELOCs are the most flexible form of home equity borrowing. They are well suited for projects or expenses with costs spread over time — like a multi-phase renovation — because you only borrow and pay interest on what you actually use.
How much can you borrow? Most lenders allow a combined loan-to-value (CLTV) of up to 85%-90%. That means your first mortgage balance plus your HELOC limit cannot exceed 85-90% of your home’s appraised value. Example: Home worth $500,000, mortgage balance $300,000, max HELOC at 85% CLTV = $125,000 ($500,000 x 0.85 – $300,000).
Draw Period vs. Repayment Period
A HELOC has two distinct phases. Understanding both is critical before you open one:
Draw Period (Typically 10 Years)
During the draw period, you can borrow up to your credit limit, repay what you borrowed, and borrow again — as many times as needed. Most HELOCs require interest-only minimum payments during the draw period, which keeps monthly payments low while the line is partially drawn. You can always pay more than the minimum to reduce principal.
Repayment Period (Typically 20 Years)
When the draw period ends, the HELOC enters the repayment period. You can no longer draw funds, and you must repay the outstanding balance in full-amortizing payments over the repayment term. Because you are now paying both principal and interest on the remaining balance, the monthly payment typically increases significantly from the draw-period minimum.
| Phase | Duration | Can Borrow? | Payment Type | Payment Example ($50K drawn at 8.75%) |
|---|---|---|---|---|
| Draw Period | 10 years (typical) | Yes | Interest-only minimum | ~$365/month |
| Repayment Period | 20 years (typical) | No | Principal + Interest | ~$442/month |
The payment shock risk. Many borrowers use a HELOC during the draw period with comfortable interest-only payments, then face a significant payment increase when the repayment period begins. If you have a large balance at the end of your draw period, plan ahead — consider refinancing the balance into a fixed-rate home equity loan or a new HELOC before the repayment period starts.
How HELOC Rates Work
Nearly all HELOCs carry variable interest rates tied to an index — most commonly the Wall Street Journal Prime Rate, which moves in tandem with the Federal Reserve’s federal funds rate target. Your HELOC rate is expressed as Prime plus a margin set by the lender.
| Component | 2026 Value | Notes |
|---|---|---|
| Prime Rate (index) | 6.75% (as of June 2026) | Moves with each Fed rate change; set by major banks |
| Lender Margin | 0% – 2% typical | Fixed portion set at origination; varies by lender and creditworthiness |
| Your HELOC Rate | Prime + Margin | Example: Prime 6.75% + 1.5% margin = 8.25% rate |
| Rate Caps | Lifetime cap: typically 18% | Periodic caps limit how much rate can change per adjustment |
| Floor Rate | Varies by lender | Minimum rate even if Prime drops; often equals initial rate |
Fixed-rate HELOC option: Some lenders offer the ability to lock a portion of your HELOC balance into a fixed rate — called a rate lock or fixed-rate advance. This gives you the flexibility of the revolving line while protecting against rate increases on the portion you have drawn and want to keep long-term.

HELOC Requirements and Qualifying
HELOCs are second mortgages and are underwritten as such — lenders evaluate your credit, income, and the equity in your home.
| Requirement | Typical Standard | Notes |
|---|---|---|
| Credit Score | 680 minimum | 720+ for best rates and highest CLTV |
| Home Equity | 15-20% equity minimum | Most lenders require at least 15% equity remaining after HELOC |
| Max CLTV | 85-90% | Combined first mortgage + HELOC cannot exceed this % of value |
| DTI Ratio | 43-50% max | Calculated with fully drawn HELOC payment in some cases |
| Income | Fully documented | W-2, pay stubs, tax returns; same standards as first mortgage |
| Property Type | Primary, second home | Most lenders do not offer HELOCs on investment properties |
| Appraisal | Required (full or AVM) | Automated valuation often used for HELOCs under $250K |
HELOC Costs and Fees
HELOCs are generally less expensive to open than a full refinance, but there are costs to be aware of:
| Fee | Typical Range | Notes |
|---|---|---|
| Origination / processing fee | $0 – $500 | Many lenders waive; shop around |
| Appraisal | $400 – $700 (if required) | Many lenders use AVM for smaller lines |
| Title search | $100 – $400 | Some lenders waive on smaller HELOCs |
| Annual fee | $0 – $100/year | Some lenders charge annual maintenance fees |
| Inactivity fee | $0 – $50/year | Charged if line is open but unused; check the terms |
| Early closure fee | $300 – $500 | Charged if you close the HELOC within 2-3 years of opening |
Many banks advertise “no closing cost” HELOCs. This is common and legitimate — the lender waives closing costs in exchange for an early closure fee if you close within 2-3 years. If you plan to keep the HELOC open for its full draw period, a no-cost HELOC is an excellent deal. Just read the terms carefully before signing.
Best Uses for a HELOC
A HELOC is a powerful financial tool when used strategically. The best applications leverage its flexibility, relatively low rate (compared to unsecured credit), and interest-only payment option:
- Home improvements and renovations. The most common use — and often the smartest. Renovation projects with multiple phases benefit from the ability to draw incrementally. Home improvements may also increase your property value, partially replenishing the equity you borrowed.
- Emergency fund backup. Opening a HELOC before you need it (when you qualify easily) and leaving it unused creates a powerful safety net. You pay no interest until you draw, and the line is there if a large unexpected expense arises.
- Bridge financing. HELOCs are sometimes used to cover a down payment on a new home before selling the current one — a short-term borrowing need with a defined payoff timeline.
- Debt consolidation (strategic). Consolidating high-interest credit card debt into a HELOC can dramatically reduce interest costs. However, this strategy converts unsecured debt to secured debt — if you cannot repay, your home is at risk. It also requires the discipline to not re-accumulate the credit card balances you paid off.
HELOC Risks to Understand
- Variable rate risk. If the Fed raises rates, your HELOC rate rises with Prime. A HELOC that starts at 8.25% could be at 10%+ if rates increase by 2 percentage points. Model your payment at higher rates before committing to a large balance.
- Your home is the collateral. Unlike a personal loan or credit card, a HELOC default can result in foreclosure. Never borrow more than you can confidently repay.
- Lender can freeze or reduce the line. During a housing market downturn or if your financial situation changes, lenders have the right to freeze or reduce your HELOC credit limit — even if you have not drawn on it. This is rare but has happened historically during severe downturns.
- Repayment period payment shock. See the warning above. If you carry a large balance into the repayment period without planning, the payment increase can be substantial.
