"Cash-Out Refinance vs. HELOC: When the Lower Rate Costs More"

The kitchen estimate came in at $80,000. Your mortgage statement is on the counter, still showing the 3.25% rate from the year you bought, and next to it is a lender's quote for a cash-out refinance at 6.75%.

Keeping a $320,000 first mortgage at 3.25% and adding an $80,000 second at 9.50% blends to 4.50% across the whole $400,000, which costs less each year than refinancing all $400,000 at 6.75%.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, helping clients since 1996. I'm licensed in fifteen states, NMLS #483943, through C2 Financial Corporation. The home equity hub compares the four ways to use your equity. This page covers one choice, replacing the first mortgage or leaving it alone, and I want you to be able to run the comparison yourself.

How a cash-out refinance differs from a HELOC or a second mortgage

A cash-out refinance is one new first mortgage, larger than the one you have, that pays off the old loan and hands you the difference at closing. Every dollar you owe gets the new rate, the new term and a new set of closing costs. Purchase, refinance and cash-out explained covers how lenders price that purpose.

A HELOC and a fixed-rate second mortgage are both second mortgages. A second mortgage is recorded behind your first mortgage, so your first mortgage stays exactly as it is.

A HELOC (home equity line of credit) is a line you draw on as you need it, usually at a variable rate, which means the rate can move up or down over time. The fixed-rate second is one amount paid to you at closing, with a fixed rate and a fixed payoff date. A lender may call it a closed-end second or a home equity loan. Second mortgages and HELOCs explained covers the choice between the two.

The blended rate, and how to figure yours

Your blended rate is your old rate and the new second's rate averaged together, weighted by how much you owe at each. It tells you what keeping your first mortgage and adding a second costs across the whole balance. That is the fair comparison next to a cash-out refinance, which also covers the whole balance.

Rate on your first mortgage      x   its balance
Rate on the second               x   the amount you need
                                     ----------------
Add the two results, then divide by the total of both balances

The second carries a higher rate than the cash-out refinance. A lender in second position gets paid after the first lender if the home is ever sold at a loss, and that risk costs something. The cash-out rate applies to your entire balance, while the second's higher rate applies only to the new money.

If the blended rate is lower, the second is the cheaper way to reach the money. If the cash-out rate is lower, replacing the first mortgage wins, and it can improve your whole position at once. Rate & Best Fit on this site prices the cash-out side for your scenario. It does not price a second, so I quote that rate myself.

How much you can borrow with each one

On a cash-out refinance, the agency guideline books cap you at 80% of your home's value on a conventional loan, 80% on an FHA loan for the home you live in, and 100% on a VA loan.

On a conventional loan, Fannie Mae's Eligibility Matrix caps a cash-out refinance of a one-unit home you live in at 80% of value. A second home or a one-unit investment property is capped at 75%. Freddie Mac's Guide sets the same limits.

On an FHA loan, HUD's FHA Handbook allows a cash-out refinance only on the home you live in. The maximum is 80% of the adjusted value, which is the value the FHA appraisal assigns. You must have owned and lived in the home for 12 months.

On a VA loan, the VA's lender pamphlet says a cash-out loan, including the funding fee, may not exceed 100% of the VA reasonable value. The funding fee is the one-time charge VA adds to the loan, and the reasonable value is the value the VA appraisal assigns.

The mortgage you are paying off also has an age rule. Fannie Mae's Selling Guide says it must be at least 12 months old.

On a second, each lender's own sheet sets the ceiling, and it is a combined figure. Combined loan-to-value, or CLTV, is your first mortgage balance plus the new second, divided by your home's value. For a one-unit home you live in, Quorum's Second Lien HELOC matrix allows 95% CLTV with a 720 or higher score, on a line from $25,000 up to $500,000 at that CLTV.

Angel Oak's Closed End Second and HELOC matrix allows its fixed-rate second to 90% CLTV at a 720 score, from $100,000 up to $500,000. How much you can borrow with a HELOC has the full tables by score and by occupancy.

On a $500,000 home with a $320,000 first mortgage, 80% of value leaves $80,000 of room, and 90% leaves $130,000.

What the closing costs look like on each

A cash-out refinance has the closing costs of a new first mortgage, because that is what it is. The lender's fees, a new lender's title policy, the appraisal, recording and, here in South Carolina, a licensed attorney's closing fee are all figured on the full new loan amount. Closing costs explained walks through each line, and most of them were paid once already on the loan you are about to replace.

The lender sheets spell out a second's costs. Quorum's HELOC matrix lists a $495 origination fee, which is the lender's charge for making the loan. It also lists a $100 processing fee, a $6 flood certification fee (the check of whether the home is in a flood zone) and a credit report fee. Settlement, title and recording fees are listed as varying.

The appraisal fee is due at application, and every other fee is taken out of the credit line when you close.

Quorum's HELOC matrix says there is no prepayment penalty, and Luxury Mortgage's Simple Seconds guidelines list prepayment penalties as not applicable. A prepayment penalty is a fee for paying the loan off early.

Angel Oak's matrix applies one only to its closed-end DSCR second lien. That is a loan behind a first mortgage on a rental property, and DSCR means the lender qualifies it on the property's rent divided by its payment.

The three-day right to cancel

On the home you live in, you get three business days to change your mind on a HELOC, a fixed-rate second, and a cash-out refinance from a new lender. The lender cannot pay out the money until those days have passed. The window runs until midnight of the third business day after you sign and receive the notice of your right to cancel and the required disclosures.

The HELOC rule is in the CFPB's text of Regulation Z, and the refinance and fixed-rate second rule is in another section of it.

There is one exception. If the same lender that holds your current mortgage refinances it, the right to cancel covers only the new money above what you already owed and the costs of the refinance.

How a fast online HELOC works covers how the three business days are counted. A HELOC on an investment property or second home covers why a property you do not live in gets no window.

When a cash-out refinance makes more sense than a HELOC

A few situations tip the comparison one way before you run the blended rate.

The rate on your first mortgage is at or above the cash-out rate. Then there is no low rate to protect, and one new loan replaces two payments with one.

You want to change the first mortgage anyway. Dropping mortgage insurance, shortening the term or moving from an adjustable rate to a fixed one all happen in the same closing as a cash-out refinance.

You need more than the 80% ceiling allows. The second-lien sheets above go to 90% and 95%, so a second may be the only one of the two that reaches the amount.

The money goes out in stages. A renovation paid in draws fits a line of credit, where a draw is each time you take money from the line, and you pay interest only on what you have taken. Angel Oak's HELOC requires an initial draw of at least 80% of the line, and Quorum's requires no draw at closing.

The five steps we take together

1. Please provide your most recent first mortgage statement, all pages, even if the last page is intentionally left blank. Its rate and balance are two of the four figures in the blended rate.
2. Please tell me the amount you need and how you will spend it. One amount all at once leans toward a fixed-rate second or a cash-out refinance, and money that goes out over time leans toward a line.
3. Please have a realistic idea of your home's value. A recent sale on your street or the county's assessment is a fine starting point.
4. Then you run the cash-out side in Rate & Best Fit. You can choose a rate option there, and that selection can change before you sign.
5. Then I quote the second from the lender sheet in effect that day, and we blend the two rates.

Two common mistakes when choosing

You may be tempted to compare the second's rate directly to the cash-out rate. The second's rate will always look higher, and on its own that does not tell you which loan costs less. The blended rate does.

You may also be tempted to run the rate tool for the second. Rate & Best Fit prices first mortgages only, so I quote a second mortgage or a HELOC to you directly.

An example, with invented figures

The figures below are made up to show the mechanism. Dana and every rate here are invented, and nothing here is a quote.

Dana lives in a home worth $500,000, owes $320,000 on her first mortgage and needs $80,000 for the kitchen. Say her first mortgage is at 3.25%, the cash-out refinance she is offered is at 6.75%, and a fixed-rate second is offered at 9.50%. The interest below is the balance times the rate for one year, before any principal is paid down.

Keep the first mortgage and add a second

First mortgage   $320,000 at 3.25%        $10,400
Second            $80,000 at 9.50%         $7,600
                                          --------
First-year interest, both loans           $18,000
Blended rate      $18,000 / $400,000          4.50%

Replace it with a cash-out refinance

New first mortgage $400,000 at 6.75%      $27,000

The second's 9.50% is the highest rate on the page, and the second is still cheaper by $9,000 in the first year. The reason is that the 3.25% stays on the other $320,000.

Now change one figure. Say Dana's first mortgage is at 7.00% instead, and the cash-out refinance is offered at 6.25%. Keeping the first mortgage now costs $22,400 on the $320,000, plus the same $7,600 on the second.

That is $30,000 for the year and a blended rate of 7.50%. The cash-out refinance costs $25,000 on the whole $400,000, so it wins by $5,000 a year while lowering the rate on the whole balance. The only thing that changed is the rate on the loan Dana already has, and that one figure decides the comparison.

Your next step

You are welcome to call me at (843) 765-0000 or email jeff@solverya.com with the rate and balance from your first mortgage statement and the amount you have in mind. I will tell you which of the second-lien sheets above your file fits, quote the second directly, and blend it with your current rate so you can see the comparison on one page.

If you would like to see the cash-out side first, Rate & Best Fit prices the cash-out refinance for your scenario, and you can choose the rate option that works best for you. That selection can change. The tool does not price a second mortgage or a HELOC.

Nothing here is a loan approval, a denial or a commitment to lend.

Common questions

Is a HELOC better than a cash-out refinance?

A HELOC is better than a cash-out refinance when the rate on your current first mortgage is low enough that the blended rate beats the cash-out rate. A HELOC or a fixed-rate second mortgage leaves your first mortgage as it is and charges a higher rate only on the new money, while a cash-out refinance replaces the rate on the whole balance with one new rate. Blend your current rate with the second's rate, weighted by how much you owe at each, and compare that to the cash-out rate. The lower number is usually the cheaper way to reach the money.

What is the maximum loan-to-value on a cash-out refinance?

The maximum loan-to-value on a cash-out refinance depends on the program. Loan-to-value, or LTV, is the loan amount against the home's value. A conventional cash-out refinance of a one-unit home you live in is capped at 80 percent, and a second home or investment property at 75 percent. An FHA cash-out refinance is capped at 80 percent of the adjusted value, on the home you live in only. A VA cash-out refinance can reach 100 percent of the VA reasonable value, including the funding fee.

How much more can I borrow with a HELOC than with a cash-out refinance?

With a HELOC you can borrow against more of your home's value than a cash-out refinance allows, because the second-lien sheets I work from go above the 80 percent agency ceiling. Quorum's Second Lien HELOC matrix allows up to 95 percent combined loan-to-value on a one-unit home you live in with a 720 or higher credit score. Angel Oak's matrix allows its fixed-rate second to 90 percent at a 720 score. Combined loan-to-value is both mortgages together, divided by your home's value.

Does a cash-out refinance have a three-day right to cancel?

A cash-out refinance has a three-day right to cancel on the home you live in, when the new loan comes from a lender other than the one that holds your current mortgage. You have until midnight of the third business day after you sign and receive the required notice and disclosures, and the lender cannot pay out the money until then. If the same lender refinances its own loan, the right covers only the new money. A HELOC on the home you live in has the same three-day window.
