Two popular ways to borrow against your home equity are a cash-out refinance and a home equity line of credit (HELOC). Both financing options allow you to access a portion of your equity to invest in your property, consolidate debt, or cover other expenses.

Which loan is best for your unique goals? Here’s a quick guide to help you decide for yourself.

The core difference: Replacing your mortgage vs. adding a second lien

The primary difference between a cash-out refinance and a home equity line of credit (HELOC) is that a cash-out refi replaces your existing mortgage, while a HELOC typically adds another loan alongside your current credit obligations.

A cash-out refinance swaps your current mortgage for a new, larger home loan. You then pocket a portion of the difference between the new loan amount and what you owe on your existing mortgage, effectively converting some of your home equity into cash. That means you’re now carrying a single loan with a new interest rate and repayment term.

On the other hand, a HELOC typically sits on top of your existing mortgage as a second loan. It leaves your original mortgage untouched while giving you access to a revolving credit line similar to a credit card. It doesn’t disturb your current mortgage rate or term.

Understanding the strategy of home equity

As a homeowner, you may think of home equity as wealth that only exists on paper until you sell your property. However, you can put your equity to work well before then.

Tapping into your equity isn’t just about borrowing money. It’s about deciding whether borrowing against your home makes sense and, if so, which approach best fits your needs. Whether you choose a cash-out refinance, a HELOC, or a home equity loan, the product you choose should align with your specific financial goals, timeline, and comfort with the associated risks. 

The rate reset problem: What a cash-out refi actually costs you

Let’s say you previously locked in a mortgage with a rate of 3% or 4%, while today’s rates are sitting north of 6.5%. A cash-out refinance would mean repricing your entire loan balance at that higher rate. In other words, you’d pay a higher interest rate on your entire loan balance, not just the equity you’re accessing.

This reset cost could make a HELOC a more sensible choice than a cash-out refi, even if the HELOC’s rate looks higher on paper. HELOC rates are also typically variable and often tied to the prime rate. As a result, they can move up or down over time. If rates fall, that variable rate could work in your favor. But if they rise, your borrowing costs and monthly payments could increase. Think about this uncertainty before you commit.

If you’re using equity to consolidate debt, your lender may exclude certain debts you’ll pay off at or before closing from your debt-to-income ratio (DTI). However, requirements vary by loan program, debt type, and lender. So ask how the lender will treat those payments before you apply.

Goal-based decision making: Which product fits your needs?

Financing large, one-time expenses

For a single, specific expense (think a full kitchen renovation, a roof replacement, a lump-sum tuition payment, etc.), a cash-out refinance may be a good choice. It gives you access to a lump sum and may offer a predictable monthly payment, making it easier to budget for.

A HELOC can also work, but its typically variable interest rate adds some uncertainty to the equation.

Managing ongoing or intermittent projects

If you need help financing a project with multiple phases rather than a single expense, a HELOC may be a better funding option. With a HELOC, you’ll draw what you need for each stage and pay interest only on the amount you borrow. As you repay the principal, that credit generally becomes available to borrow again during the draw period.

If you were to take out a lump sum with a cash-out refinance for a long-term, multi-phase project, you’d be paying interest on the full amount from day one. That approach could add considerably to your borrowing costs.

Strategic debt consolidation: The blended rate calculation

You may be tempted to consolidate your debt through a cash-out refinance because the new mortgage rate may be dramatically lower than the rates on your credit cards or personal loans. Just keep in mind these two trade-offs:

• You’re rolling short-term unsecured debt into a mortgage that could have a repayment term of up to 30 years and a higher interest rate than your original mortgage.
• You’re converting unsecured debt into a secured loan that is backed by your home.

The “blended rate” calculation uses the balances and interest rates on the debts you plan to pay off to estimate their combined interest rate. You can then compare that rate with the rate on your new mortgage. However, a lower rate and monthly payment don’t necessarily mean you’ll save money. A longer repayment term and closing costs could cause you to pay more overall. That’s why it’s important to compare both the monthly payments and total costs before you decide.

Meanwhile, you can also use a HELOC to consolidate your debt without replacing your current mortgage. A HELOC preserves your existing mortgage rate and term, although it adds a separate debt secured by your home.

The case for opening a HELOC before you need it

One of the more underrated uses of a HELOC is opening one before you need it. Because you pay no interest on an unused credit line, it can function as a backup source of emergency funds. That said, some lenders charge annual fees or inactivity fees, which could make this strategy a nonstarter.

A cash-out refinance doesn’t serve this purpose well because of the interest you’ll pay each month. Whether or not you’re actually using the money, you’ll pay interest on the cash you borrowed even if it’s merely gathering dust in your bank account.

The mechanics of a cash-out refinance

Before taking the time to run the numbers on whether a cash-out refinance makes sense for you, it’s important to understand how it actually works. Here’s what to expect from the application process to what you’ll pay at closing. 

How the process works: From appraisal to close

A cash-out refinance follows the same basic process as your original mortgage: Apply, get a home appraisal, go through underwriting, and then close on the loan. The process often takes around 30 to 45 days, although the timeline can vary.

Conventional and FHA cash-out refinances on one-unit primary residences generally have a maximum loan-to-value ratio (LTV) of 80%. That means you need to keep at least 20% equity in your home after closing. Fannie Mae, Freddie Mac, and the FHA establish these limits for loans that follow their respective guidelines, although individual lenders may impose stricter requirements.

Fixed-rate stability and long-term amortization

The big benefit of a cash-out refinance with a fixed interest rate is a predictable monthly principal-and-interest payment. That portion of your payment stays the same for the entire loan, making it easier to budget.

Again, the tradeoff is that you may effectively restart the clock on your home loan. If you’re 10 years into a 30-year mortgage and refinance into a new 30-year loan, you’ve extended your payoff timeline by a decade.

Choosing a shorter loan term can offset some of that cost, though your monthly payment will likely be higher. However, you’ll generally pay less interest over the life of the loan. 

Closing costs and speed to close

The closing costs for a cash-out refinance generally run between 2% and 5% of the loan amount. For a $300,000 refi, that’s around $6,000 to $15,000. You may be able to roll these costs into your new loan, but doing so increases your loan balance and reduces the amount of cash you receive.

A cash-out refinance can also take a month or longer to close, making it a poor fit for anyone who needs funds quickly.

The mechanics of a HELOC

Beyond your interest rate, a HELOC works differently from a traditional loan in a few ways—from how you spend the money to how you pay it back and eventually close out the credit line.

Draw period vs. repayment period

A HELOC consists of two phases:

• A draw period, which begins when you open the HELOC and typically lasts three to 10 years, depending on the lender. During the draw period, you can use and repay your credit line as needed.
• A repayment period, during which your ability to borrow ends and you must repay your outstanding balance. Repayment periods commonly last 10 to 20 years, with monthly payments covering both principal and interest.

Note that, during the draw period, you may have the option to make interest-only payments. But if you get used to those smaller monthly payments, your budget can take a hit once you enter the repayment phase. During repayment, your monthly payments can be considerably higher, depending on how much you owe.

Speed to close and upfront costs

HELOCs generally take two to six weeks to close, depending on the lender and your circumstances. They also typically have lower upfront costs than cash-out refinances.

You may notice some lenders advertising no closing costs on a HELOC. However, these often come with trade-offs such as a higher rate or an early cancellation fee if you close your line within the lender’s specified period.

Qualification requirements

Cash-out refinances and HELOCs have similar underwriting processes. But the specific requirements are worth knowing before you apply.

LTV: How much equity can you actually access?

Both financing options use your home’s value to help determine how much you can borrow. Cash-out refinance lenders consider your loan-to-value ratio (LTV), while HELOC lenders generally consider your combined loan-to-value ratio (CLTV), which includes your existing mortgage and the new credit line. 

For a conventional cash-out refinance on a one-unit primary residence, the maximum LTV is generally 80%, meaning you need to retain at least 20% equity. HELOC requirements vary, but many lenders require homeowners to retain 15% to 20% equity. 

For example, if your home is worth $500,000, your combined mortgage balance and any new borrowing generally can’t exceed $400,000 to $425,000.

DTI and credit score

DTI limits vary by lender, loan type, and underwriting method. For certain conventional loans, Fannie Mae allows a DTI of up to 45% for manually underwritten loans that meet specific credit score and reserve requirements, while loans underwritten through its automated system may allow a DTI as high as 50%. However, cash-out refis may be subject to lower limits.

For HELOCs, some lenders may also allow DTIs up to 50%. But lender criteria varies. 

Tax implications

Under current IRS rules, interest on HELOC funds and cash-out refinance proceeds is generally deductible only when you use the money to buy, build, or substantially improve the home you used to secure the loan. Using the funds for debt consolidation, everyday expenses, or other purposes generally doesn’t qualify.

You must also itemize deductions to claim the home mortgage interest deduction.

Decision guide: Which option is right for you?

At this point, you probably already have a sense of which loan type fits your situation. But just in case you’re still on the fence, below is a quick guide to help you decide.

When to choose a cash-out refinance

You might favor a cash-out refinance when current mortgage rates are below (or even near) your current mortgage rate. That way, the cost of resetting your rate is small and could even work in your favor.

A cash-out refi can also be a better fit if you need a large lump sum for a specific expense. A fixed-rate loan provides the predictability of a fixed monthly principal-and-interest payment, which can make budgeting easier.

When to choose a HELOC

A HELOC can be a better choice when your current mortgage rate is low enough that you don’t want to change it. Remember, replacing a low-rate mortgage with a higher-rate cash-out refinance could add considerably to your borrowing costs.

It can also be well suited for those looking to finance ongoing projects or expenses when you aren’t certain how much you’ll need. A revolving credit line gives you flexibility that a lump sum can’t match.

Additionally, a HELOC may be a good option if you want the ability to access money without paying interest immediately. If you’d like a backup credit line for emergencies, you can let a HELOC sit and only pay interest on what you use. Just be aware that some lenders charge annual fees and may freeze or reduce the line under certain circumstances.

The takeaway

Before you commit to either a cash-out refinance or a HELOC, be sure to run the numbers for your specific situation. Your current mortgage rate, your home’s appraised value, the amount of equity you need to access, and how long you plan to stay in the home all play a role in which option may be the better fit.

A mortgage advisor can help you compare both choices using up-to-date rate quotes. This can help you stress-test the numbers and understand how each option might affect your monthly budget and total borrowing costs.

Frequently asked questions

Does a cash-out refinance affect my mortgage rate?

Yes, a cash-out refinance replaces your existing mortgage with a new loan at a new interest rate. If current rates are higher than your existing rate, refinancing could increase your borrowing costs considerably.

How long does it take to close on a cash-out refinance vs. a HELOC?

A cash-out refinance often takes around 30 to 45 days to close, while a HELOC generally takes two to six weeks. Timelines differ by lender and borrower circumstances.

How much equity do I need for a cash-out refinance or HELOC?

For a conventional cash-out refinance on a one-unit primary residence, you’ll generally need to keep at least 20% equity in your home after the deal closes. HELOC requirements vary by lender, but may require you to retain 15% to 20% equity.

Do HELOCs have fixed or variable interest rates?

HELOC rates are usually variable, though some lenders offer fixed-rate HELOCs or will let you convert some or all of your balance to a fixed rate.

Is a HELOC or cash-out refinance better for debt consolidation?

Neither a HELOC nor a cash-out refinance is always better for debt consolidation, as each offers different advantages. If you’d like a fixed interest rate, a cash-out refinance may be the better fit. If you don’t want to replace your existing mortgage and its interest rate, a HELOC may make more sense.
