Borrowing Against Your Home at the Lowest Possible Cost

For most households, the equity in their home is the largest pool of money they will ever sit on -- and the cheapest to borrow against. After a few years of payments, or a run of rising home values, you may be holding a sizable amount. Equity is just the difference between what your home would sell for today and what you still owe. Because that borrowing is secured by the house, it almost always carries a far lower rate than credit cards or personal loans. The trick to saving money is matching the right product to your need and shopping the rate hard before you sign.

Three Ways to Tap Equity, Ranked by Cost

Home Equity Loan (a Second Mortgage)

A home equity loan gives you a single lump sum at a fixed rate, repaid over a set term of roughly 5 to 30 years. It sits as a second mortgage behind the one you already have. It works best when you know the exact amount you need for a defined purpose, like a renovation or consolidating several higher-rate debts into one cheaper payment.

• A fixed rate and level payment that make the cost easy to budget
• Typical rates: 6.5%-10%, depending on your credit and loan-to-value ratio
• Closing costs: about 2%-5% of the amount borrowed
• Best for: one large expense with a price you already know

HELOC (Home Equity Line of Credit)

A HELOC works like a credit card secured by your house. You get a revolving line at a variable rate and draw on it as needed during the "draw period," which usually runs about 10 years. A "repayment period" of 10 to 20 years follows, when you pay back what you used. Because you only pay interest on what you draw, it can be the cheapest option for irregular costs.

• A variable rate that can raise your payment if rates rise
• Typical rates: the prime rate plus anywhere from 0.5% to 3%
• Flexible draws: borrow only what you need, only when you need it
• Best for: ongoing costs, multiple projects, or a low-cost emergency reserve

Cash-Out Refinance

A cash-out refinance replaces your existing mortgage with a larger one and pays you the difference in cash. Unlike the other two, you end up with just one mortgage payment -- which can be the lowest-cost route when current rates are at or below your existing rate. Our refinance guide walks through the details.

How Much Can You Borrow?

Lenders generally let you borrow up to 80-85% of your home's appraised value after subtracting your current mortgage balance. That figure is your combined loan-to-value, or CLTV, ratio.

Example: If your home appraises at $400,000 and you owe $250,000, an 80% CLTV cap leaves you $70,000 to borrow ($400,000 x 80% = $320,000, minus the $250,000 you still owe).

Smart, Money-Saving Uses for Equity

1. Value-adding improvements such as a kitchen, bathroom, or roof that raise the home's worth
2. Consolidating debt when the equity rate sits well below what your current balances charge, cutting your interest cost
3. Education costs after you have exhausted your lower-cost federal student loan options
4. A low-cost safety net by opening a HELOC and leaving it untouched until you actually need it

Uses That Cost You in the Long Run

• Funding a lifestyle you cannot otherwise afford -- vacations or luxury purchases
• Speculative bets like individual stocks or cryptocurrency
• Paying off debt without changing the habits behind it -- you will rack up the old debt again, now on top of the equity loan

What It Takes to Qualify for the Best Rate

• Credit score: 680 or higher for the lowest pricing; most lenders require at least 620
• Debt-to-income ratio: under 43%, ideally below 36%
• Equity: at least 15-20% left in the home after the new loan
• Steady income: documented through pay stubs, tax returns, and bank statements

The Risks Worth Weighing

The fundamental risk with any equity product is that your home is the collateral. Miss payments and the lender can foreclose. HELOCs carry a second risk: payment shock, which hits when variable rates rise or when the draw period ends and your monthly payment jumps as repayment begins. Either can wipe out the savings you set out to capture.

Equity is a powerful, low-cost way to borrow, but it is never free money. Every dollar you take out hands a piece of your ownership back to a lender. Borrow it against the lowest rate you can find, with a clear plan to repay, and it can move you toward your goals; spend it carelessly and you put your home itself at risk.
