HELOC vs. Cash-Out Refinance: Real Math for Nashville and Huntsville Homeowners

If you bought or refinanced in 2020 or 2021, you probably have a mortgage rate that starts with a 2 or a 3. You also probably have a lot more equity than you did then. Sooner or later, life asks for some of that equity back. A new roof. A kitchen that hasn't been touched since 1998. College. A credit card balance that got out of hand.

There are two main ways to get at that money: a cash-out refinance or a home equity line of credit, also called a HELOC. With 30-year rates averaging 7.40% in mid-October 2026, the choice between them can easily be worth several hundred dollars a month. Here's how they work, and the actual math on a Nashville home and a Huntsville home.

The short answer

If your current mortgage rate is well below today's rates, a HELOC usually costs less each month because you keep your low rate on most of your debt. A cash-out refinance tends to make more sense when your current rate is already close to today's rates, when you want one fixed payment, or when you need a large amount of cash in one lump sum.

How each option works

Cash-out refinance

You replace your existing mortgage with a new, larger one and take the difference in cash. Everything you owe now carries the new rate. You get one loan and one fixed payment, and you pay full closing costs, similar to when you bought the home. For a conventional cash-out refinance on a primary home, lenders generally cap the new loan at 80% of the home's value.

HELOC

A HELOC is a second loan that sits behind your current mortgage. It works like a credit card secured by your house. You draw what you need, when you need it, and you pay interest only on what you've used. A common setup is a 10-year draw period, often with interest-only payments, followed by a 20-year repayment period. Most HELOCs have a variable rate tied to the prime rate, so the payment can go up or down.

Bankrate's national average HELOC rate was 7.34% as of October 14, 2026, while Curinos data put the average at 7.54% on October 13. The average fixed-rate home equity loan, a close cousin with a fixed payment, was 7.50%.

The math: two real examples

Both examples use a 7.625% example rate for the cash-out refinance, since cash-out loans usually price a bit above the 7.40% Freddie Mac average, and the 7.34% Bankrate average for the HELOC. Payments are principal and interest only.

Example: a Nashville home

You bought in Nashville in October 2021 with a $360,000 loan at 3.50%. Your principal and interest payment is $1,616.56, and after five years you owe about $322,909. Today the home is worth about $510,000, right at the September 2026 single-family median for Greater Nashville. You want $60,000 for a renovation.

Option A is a cash-out refinance to a new $382,909 loan, about 75% of the home's value. Option B keeps your current loan and adds a $60,000 HELOC, bringing your combined loan-to-value to the same 75%.

	Option A: cash-out refi	Option B: keep your loan + HELOC
New loan or line	$382,909 first mortgage	$60,000 HELOC; first mortgage stays at $322,909
Rate	7.625% fixed (example)	3.50% fixed on the first, 7.34% variable on the HELOC
Monthly P&I, draw period	$2,710.21	$1,983.56 ($1,616.56 + $367.00 interest-only)
Monthly P&I, HELOC repaid over 20 years	$2,710.21	$2,094.06 ($1,616.56 + $477.50)
Interest paid, first 5 years	$142,447	$74,841
Blended rate on all debt	7.625%	About 4.10%

Option B costs about $727 less per month during the draw period and about $616 less if you pay the HELOC off over 20 years. Over the first five years, it saves roughly $67,606 in interest. For the cash-out refinance to cost the same each month, the HELOC rate would need to climb to about 22%.

Example: a Huntsville home

You bought in Huntsville in October 2021 with a $240,000 loan at 3.25%. Your principal and interest payment is $1,044.50, and after five years you owe about $214,336. Today the home is worth about $335,000, right at the September 2026 median for Madison County. You want $45,000 for a renovation.

Option A is a cash-out refinance to a new $259,336 loan, about 77% of the home's value. Option B keeps your current loan and adds a $45,000 HELOC, bringing your combined loan-to-value to the same 77%.

	Option A: cash-out refi	Option B: keep your loan + HELOC
New loan or line	$259,336 first mortgage	$45,000 HELOC; first mortgage stays at $214,336
Rate	7.625% fixed (example)	3.25% fixed on the first, 7.34% variable on the HELOC
Monthly P&I, draw period	$1,835.57	$1,319.75 ($1,044.50 + $275.25 interest-only)
Monthly P&I, HELOC repaid over 20 years	$1,835.57	$1,402.62 ($1,044.50 + $358.13)
Interest paid, first 5 years	$96,476	$48,999
Blended rate on all debt	7.625%	About 3.96%

Option B costs about $516 less per month during the draw period and about $433 less if you pay the HELOC off over 20 years. Over the first five years, it saves roughly $47,477 in interest. For the cash-out refinance to cost the same each month, the HELOC rate would need to climb to about 21%.

What if HELOC rates go up?

This is the fair question. The Federal Reserve raised its benchmark rate in September 2026, and markets expect at least one more hike by year end. HELOC rates usually move with the prime rate, which follows the Fed.

HELOC rate	Huntsville: $45,000 interest-only	Nashville: $60,000 interest-only
7.34% (today's average)	$275.25	$367.00
7.84% (up 0.50%)	$294.00	$392.00
8.34% (up 1.00%)	$312.75	$417.00

Even a full one-point increase adds only about $38 a month in the Huntsville example and $50 in Nashville. The cash-out refinance still costs hundreds more, because it reprices your whole balance, not just the new money.

If a variable rate keeps you up at night, ask about a fixed-rate home equity loan or a HELOC with a fixed-rate lock option. You still keep your low first mortgage.

When a cash-out refinance makes more sense

Your current rate is already close to today's rates, so you aren't giving up much.
You need a large lump sum and want it on one fixed schedule.
You're consolidating high-rate debt and want one payment you can't accidentally run back up.
You need to change the loan itself, such as removing a co-borrower after a divorce.
Your first mortgage has an adjustable rate or a balloon you want to get rid of.

When a HELOC makes more sense

Your first mortgage rate is well below today's rates.
You need money in stages, like a renovation paid out as work gets done.
You plan to pay the balance down fairly quickly.
You want lower upfront costs. HELOC fees are often lower than a full refinance, though they vary by lender.

Questions to ask before you choose

What is the rate today, and what index and margin set it later?
Is there a rate cap, and is there an option to lock part of the balance at a fixed rate?
How long is the draw period, and what does the payment become when repayment starts?
What are the total closing costs, annual fees, and any early closure fees?
What is the maximum combined loan-to-value the lender allows?

The bottom line

A low mortgage rate is one of the most valuable things a homeowner can have right now. Before you refinance it away to get cash, run the numbers both ways. In both examples above, keeping the low rate and adding a HELOC cost hundreds less per month and tens of thousands less in interest over five years. Your numbers will be different, and that's the point of running them.
