How Much Equity Do You Need to Borrow Against Your Home?

The Short Answer

1. Keep 15% to 20% of Your Home's Value

Most lenders want you to keep at least 15% to 20% equity after the new loan closes. Put another way, your first mortgage plus the new loan should stay at or below 80% to 85% of what your home is worth. That rule covers a home equity HELOC, a home equity loan, and most cash-out refinances.

2. Your Exact Number Depends on the Lender

Some lenders go up to 90% for strong borrowers, and others stop at 80%. Guidelines differ a lot between home equity line of credit lenders, so the same house can get you a different limit depending on who you ask.

What Home Equity Actually Means

1. The Basic Formula

Equity is your home's current market value minus what you still owe. If your house is worth $700,000 and your mortgage balance is $400,000, you have $300,000 in equity. That's about 43% of the home.

2. Why You Can't Borrow All of It

Here's where people get tripped up. Having $300,000 in equity does not mean you can borrow $300,000. Lenders leave a cushion in case prices slip. That cushion protects them, and it protects you from ending up owing more than the house is worth.

How to Calculate Your Borrowing Limit

1. Find the CLTV Limit

CLTV stands for combined loan-to-value. You add your current mortgage balance and the new loan, then divide by your home's value. Lenders set a ceiling on that percentage, usually 80% to 90%.

2. Run a Real Example

Take that same $700,000 home with a $400,000 mortgage.

• At an 80% limit, total debt can reach $560,000, so you could borrow up to $160,000.
• At an 85% limit, total debt can reach $595,000, so you could borrow up to $195,000.
• At a 90% limit, total debt can reach $630,000, so you could borrow up to $230,000.

3. Start With a Realistic Home Value

Zillow-style estimates are a starting point, not the final word. The lender's valuation is the one that counts. Check recent sales of similar homes on your street or in your neighborhood, and be honest about condition. A dated kitchen or a worn roof can pull an appraisal down.

HELOC vs. Home Equity Loan vs. Cash-Out Refinance

1. HELOC

A HELOC works like a credit card backed by your house. You get a credit line, draw what you need during the draw period, and pay interest on what you use. It fits costs that arrive in pieces, like a phased remodel. If you're leaning toward a home equity HELOC, your first mortgage and its rate stay exactly as they are.

2. Home Equity Loan

You get one lump sum and pay it back with a fixed payment. It suits a single expense with a known price, like a roof replacement or a tuition bill. Equity requirements look a lot like a HELOC's.

3. Cash-Out Refinance

This replaces your whole mortgage with a bigger one and hands you the difference. Conventional loans often cap near 80% of the home's value, while some programs, like VA loans, can go higher for eligible borrowers. The big trade-off is that you give up your existing rate. If you locked in a low one, that can cost you real money every month.

What Else Lenders Check

1. Credit Score

Most lenders look for a score in the mid-600s or higher. Better scores earn better rates and higher limits. If your score is borderline, a few months of clean payments can change the offer you get.

2. Debt-to-Income Ratio

This compares your monthly debt payments to your monthly gross income. If most of your paycheck already goes to bills, extra equity won't fix that. Lenders want proof you can carry another payment without strain.

3. Income and Payment History

Expect to show pay stubs or tax returns, and bank statements if you're self-employed. A clean mortgage history matters too. Late payments in the past year raise red flags quickly.

How to Compare Lenders

1. Ask About the Maximum CLTV

When you compare home equity line of credit lenders, start with one question: what's the highest combined loan-to-value you'll approve for my situation? A lender who stops at 80% may leave money on the table that another would offer.

2. Check Fees, Rate Type, and Draw Period

Look at closing costs, annual fees, and whether the rate is variable. Ask how long you can draw funds and what happens when repayment starts. A low intro rate means little if the payment jumps later.

3. Look for a Real Person on the Other End

Taylor Weiner has spent 20 years in mortgage lending, and the team holds a 5.0 rating on Google with 450+ five-star reviews. That kind of track record is worth asking any lender about. If you want a fast start, the digital home equity HELOC application takes about five minutes, uses a soft credit pull, and can fund in as few as five days with no in-person appraisal. It's fully automated with strict criteria, so some applicants get declined. If that happens, you can start a full application and have an in-house underwriter review your file.

Ways to Raise Your Borrowing Power

1. Pay Down Your Mortgage Principal

Every extra dollar toward principal raises your equity. A few extra payments a year will move your CLTV in the right direction. It's slow, but it works.

2. Clean Up Your Credit and Debts

Pay down credit card balances and avoid opening new accounts right before you apply. Both help your score and your debt-to-income ratio.

3. Get an Updated Valuation

If home prices have climbed in your area since you bought, you may have more equity than you think. A fresh valuation can change the whole picture.

Risks to Weigh Before You Borrow

1. Your Home Secures the Loan

If you can't repay, the lender can foreclose. Borrow for things that add value or solve a real problem, and be careful using it for everyday spending.

2. Variable Rates Can Rise

Most HELOCs carry variable rates, so your payment can go up. Build a buffer into your budget before you draw.

3. Values Can Drop

If your home's value falls, your equity shrinks. Some home equity line of credit lenders can freeze or reduce an unused credit line when that happens. Borrowing well under your maximum gives you breathing room.

Conclusion

Plan on keeping at least 15% to 20% of your home's value untouched, which usually means your total loans stay under 80% to 85% of what the house is worth. Credit, income, and existing debts still shape the final offer, and the product you pick changes the math. Work out your number first, compare lenders on more than just rate, and borrow only what you can repay comfortably.

FAQs

1. Can I borrow with less than 20% equity?

Sometimes. Some lenders allow up to 90% CLTV, which means 10% equity, usually with stricter credit standards.

2. Does applying hurt my credit score?

A hard credit check can cause a small, temporary dip. Some digital applications use a soft pull first, which doesn't affect your score.

3. Is the money I borrow taxable?

No, it's a loan, not income. Interest deductibility depends on how you use the funds, so ask a tax professional.

4. How long does approval take?

Traditional applications with an appraisal can take a few weeks. Digital options can be faster for approved applicants.

5. Which is better, a HELOC or a cash-out refinance?

A HELOC keeps your current mortgage rate in place. A refinance replaces it, which can cost you if your rate is low.
