How to Pay for a Remodel With Your Home Equity

Quick answer

You can fund a remodel from home equity three main ways: a cash-out refinance replaces your mortgage with a larger one and hands you the difference in cash; a home equity loan is a second loan for a lump sum with its own payment; and a HELOC is a credit line you draw from as the work goes. A cash-out refinance often fits big, all-at-once projects, while a HELOC fits phased work where you don't need all the money on day one. The right pick depends on your project size and how your current mortgage rate compares to today's.

First, how much equity can you actually use?

Equity is the part of your home you own outright — the value minus what you still owe. But you can't borrow all of it. Most lenders let you borrow up to roughly 80% of the home's value across every loan on the property combined. So if your home is worth $600,000, 80% is $480,000; subtract your current $300,000 balance and you've got about $180,000 of usable equity for a remodel. That 80% line is a rule of thumb, not a promise — programs vary — but it's the number to start your planning from.

Usable equity is not the same as total equity. The 80% cap is why the two numbers differ.

Option 1: Cash-out refinance

A cash-out refinance replaces your existing mortgage with a new, larger one and gives you the difference as cash for the remodel. You end up with a single loan and a single payment. It tends to fit big, do-it-all-at-once projects — a full kitchen, an addition, an ADU — where you want the whole budget in hand. The trade-off is that you're refinancing your entire mortgage, so it works best when today's rates are near or below the rate you already have. Our full explainer on the cash-out refinance walks through the numbers.

Option 2: Home equity loan

A home equity loan is a second loan that sits behind your current mortgage. You get a lump sum, you leave your first mortgage exactly as it is, and you make a second, separate payment at a fixed rate. This is the one to look at when you already have a low mortgage rate you don't want to give up. You keep that good first loan and add a smaller second loan just for the remodel. The payment is predictable because the rate is fixed, which some people prefer for budgeting a defined project.

Option 3: HELOC (home equity line of credit)

A HELOC is a credit line secured by your home. Instead of a lump sum, you get a limit you can draw from as the project moves along, and you generally pay interest only on what you've actually used. That makes it a natural fit for phased remodels — you pull money for the kitchen now, the bathroom next year — without borrowing the full amount up front. Like a home equity loan, it leaves your first mortgage untouched. The rate is usually variable, so the payment can move over time, which is the main thing to weigh.

How the three compare

Seeing them side by side makes the choice clearer. Here's the plain version of what each tool does best.

Illustrative only. The right fit depends on your project, your equity, and how your current rate compares to today's.

The real deciding factor: your current rate

Once you know your project, the choice usually comes down to one number — the rate on your existing mortgage. If your current rate is high, or today's rates are similar, a cash-out refinance can roll everything into one loan without much penalty. If you're sitting on a low rate from a few years back, giving it up to refinance the whole balance rarely makes sense, so a HELOC or home equity loan that leaves that first mortgage alone is usually the smarter move. That single comparison points most people to the right tool.

None of these guarantee a rate or approval — they depend on your equity, credit, and income. The point is to match the structure to your situation before you apply.

A quick word on ADUs and value

In California, a lot of remodel questions lately are about ADUs — the backyard or garage-conversion units that can house family or bring in rent. Equity can fund them the same three ways above. Just keep expectations grounded: a remodel may add value and, with an ADU, may add income, but neither is guaranteed, and costs run over more often than under. Build in a cushion and treat the projected payoff as a hope, not a certainty.

Common questions

How much equity can I use for a remodel?

Usually up to about 80% of your home's value across all loans combined. On a $600,000 home that's $480,000; subtract your current balance to find your usable equity. The 80% figure is a common rule of thumb — some programs differ — so it's a planning starting point, not a guarantee.

Is a cash-out refinance or a HELOC better for a remodel?

It depends on your project and your current rate. A cash-out refinance suits one big all-at-once job and works best when today's rates are near or below yours. A HELOC suits phased work and leaves your first mortgage alone, which matters if you have a low rate you don't want to lose.

Will a remodel raise my home's value enough to pay for itself?

Sometimes, but there's no guarantee. Some projects return more of their cost than others, and California costs can run high. Treat any added value or ADU rent as a hopeful estimate, not a sure thing, and don't borrow assuming the project pays for itself.

Can I use home equity to build an ADU?

Yes. An ADU can be funded the same three ways as any remodel — cash-out refinance, home equity loan, or HELOC. Pick the structure that fits how your rate compares to today's and how you'll pay for the work, and budget a cushion since construction costs often run over.

Do I need great credit to tap my equity?

You need to qualify, but requirements vary by program and by how much of your equity you're using. Income, credit, and the loan-to-value all factor in. The best move is to run your real numbers with a broker so you know what you'd qualify for before you plan the project around it.
