Do You Have Enough Equity?
Enter your home value and mortgage balance to see your LTV, available headroom, and whether you likely meet equity requirements.
Minimum Equity Requirements Explained
Lenders don't just look at how much equity you have — they look at your combined loan-to-value (CLTV): the ratio of all outstanding liens (first mortgage + HELOC) to the home's current value. Most lenders cap CLTV at 80–85%.
Example: A $500,000 home with a $350,000 first mortgage has a 70% first-mortgage LTV. At 85% CLTV, the lender would allow up to $425,000 in total debt — meaning a HELOC of up to $75,000 ($425K − $350K). At 80% CLTV, the HELOC limit drops to $50,000.
Why 80% vs 85% CLTV matters
Lenders who allow 85% CLTV typically charge a higher margin (rate) to compensate for the additional risk. Staying at or below 80% CLTV often unlocks the lowest rate tier and the most lender choices. If you're between 80% and 85% CLTV, it may be worth making a few extra mortgage payments to cross the 80% threshold before applying.
Credit Score Requirements
Your credit score determines not just approval odds but the margin lenders will charge. A borrower at 680 vs 720 can expect to pay 0.50–0.75% more in rate — on a $100,000 HELOC, that's $500–$750 in additional interest per year.
| Credit Score | Approval Odds | Rate Impact | What to Know |
|---|---|---|---|
| 720+ Best tier | High — most lenders | Best rates available (prime +0.50%–+1.00%) | Negotiate directly; you have leverage |
| 680–719 Good | Good — most lenders | Moderate rates (prime +1.00%–+2.00%) | Shop 3+ lenders; margins vary widely at this tier |
| 640–679 Fair | Possible — selective lenders | Higher rates (prime +2.00%–+2.75%) | Credit unions often more flexible than banks at this tier |
| 620–639 Minimum | Limited — fewer lenders | Significantly higher (prime +2.75%–+3.50%) | Consider improving score before applying — 6–12 months of targeted improvement can move you to the next tier |
| Below 620 | Very unlikely | N/A | Focus on credit building first; most HELOC lenders have a hard minimum of 620 |
Debt-to-Income Ratio Requirements
Your DTI ratio is your total monthly debt obligations divided by your gross monthly income. Most HELOC lenders cap DTI at 43%, though some premium lenders accept up to 50% for strong-credit, low-LTV borrowers.
Important: lenders calculate DTI using the fully amortizing HELOC payment — the payment you'd make during repayment, not the interest-only draw period payment. This is higher than what you'll actually pay during the draw period, so your qualifying payment will be larger than your initial actual payment.
DTI calculation example
Gross monthly income: $8,500. Current monthly debts: $2,100 (mortgage $1,600 + car $300 + student loans $200). Proposed HELOC repayment payment (fully amortized): $650/month. New DTI = ($2,100 + $650) / $8,500 = 32.4%. Well within the 43% threshold. If your current DTI is already above 35%, model your HELOC repayment payment before applying to confirm you'll qualify.
Documentation Required
Most HELOC applications require the following:
- Income verification: Last 2 years of W-2s or 1099s; most recent 30 days of pay stubs; 2 years of tax returns if self-employed
- Property documentation: Homeowner's insurance declarations page; current mortgage statement; HOA statement if applicable
- Identity: Government-issued ID; Social Security number for credit pull authorization
- Assets: 2–3 months of bank statements; investment account statements if using assets for qualification
- Appraisal: Lender orders this — a full appraisal (typically $400–$700) or an automated valuation model (AVM) depending on the lender's risk assessment
How Long HELOC Approval Takes
Typical HELOC timeline from application to funding is 2–6 weeks. The most common bottlenecks are appraisal scheduling and income documentation collection.
- Application (Day 1–3)Submit online or in-branch. Lender pulls credit and reviews initial documentation.
- Processing (Days 3–14)Underwriter reviews income, assets, employment. Appraisal ordered.
- Appraisal (Days 7–21)Full appraisal requires scheduling a home visit. AVM is instant. This is the most variable step.
- Underwriting decision (Days 14–28)Lender issues conditional approval or approval. Any conditions (additional documentation) must be satisfied.
- Closing (Days 21–42)You sign documents. A federally mandated 3-day right of rescission period begins. Funds available on Day 4 after signing.
Credit unions often close HELOCs in 2–3 weeks. Large banks can take 4–6 weeks. If you have a time-sensitive project, ask your lender for their average time-to-close before applying.
Frequently Asked Questions
What credit score do you need for a HELOC?
Most lenders require a minimum of 620. However, a 620 score will result in a significantly higher rate than a 720+ score — often 1.5–2% higher APR. For the best available rates, aim for 720+. Improving your score from 670 to 710 before applying is often worth a 6-month wait, as it can save thousands in interest over the life of the line.
How much equity do you need for a HELOC?
Most lenders require your combined loan-to-value (CLTV — first mortgage + HELOC) to stay at or below 80–85%. This means you need at least 15–20% equity remaining in your home after accounting for the full HELOC credit line. On a $400,000 home, you'd need a first mortgage balance of $260,000 or less to qualify for an $80,000 HELOC at 85% CLTV ($400K × 85% = $340K max total debt; $340K − $260K = $80K available).
Can you get a HELOC with a high DTI?
The standard DTI limit is 43%, but some lenders go up to 45–50% for strong-credit, low-LTV borrowers. If your DTI is between 40–45%, focus on getting your credit score as high as possible and keeping your LTV well below 80% — these factors can compensate in some lenders' underwriting models. A mortgage broker familiar with HELOC products can identify which lenders are more flexible on DTI in your specific situation.
Do I need a full appraisal for a HELOC?
Not always. Many lenders use automated valuation models (AVMs) for lower-LTV, straightforward properties. A full appraisal is typically required when: your CLTV is above 80%, the property is unique or rural, the lender's AVM returns a low-confidence value, or the loan amount is above a certain threshold (varies by lender). If an appraisal is required, expect to pay $400–$700 and 1–2 weeks for scheduling.
Can I get a HELOC on an investment property?
It's significantly harder. Most standard HELOC lenders require the property to be a primary or secondary residence. Some portfolio lenders and credit unions do offer HELOCs on investment properties, but with stricter requirements: higher credit score (740+), lower CLTV (≤75%), higher rate margins, and more documentation. If you own a rental property with significant equity, explore a home equity loan or cash-out refinance on that property instead, as more lenders offer those products for investment properties.
Does opening a HELOC hurt my credit score?
Applying for a HELOC triggers a hard credit inquiry, which typically reduces your score by 5–10 points temporarily. Opening the account adds a new credit line, which initially lowers your average account age (slightly negative) but improves your credit utilization ratio (positive) if you don't draw from it. Over 12–18 months, a HELOC with a low or zero balance typically has a neutral to positive effect on your credit profile. Shopping multiple lenders within a 45-day window counts as a single inquiry for scoring purposes.
