Should I Sell My House If I Have a Low Rate?

If you bought or refinanced in Chattanooga before 2022, you're probably sitting on a rate that starts with a 2, a 3, or a 4. And that's exactly why you haven't sold, even though part of you wants to.

Right now the 30-year fixed is averaging 6.65%. About 90% of homeowners around here are sitting below 6%. That gap is the whole reason this market feels stuck. It's why your neighbor hasn't put a sign in the yard even though they've talked about moving for two years. It's why you keep pulling up Zillow, doing the math in your head, and closing the tab.

You're not imagining it. The math genuinely feels backwards. But feeling backwards and being backwards aren't always the same thing. So let's run the actual numbers instead of guessing at them.

(I walk through all of this on video too, if you'd rather watch than read: Should I Sell My House If I Have a Low Rate?)

What giving up your rate actually costs

Say you've got $300,000 left on your loan at 3%. Your principal and interest payment is around $1,265 a month. Take that same $300,000 balance at 6.65%, and you're looking at about $1,930 a month. That's a $665 jump every single month, for the exact same loan amount — roughly $8,000 more a year.

That number's real. I'm not going to pretend it isn't. But it's only half the equation. When you sell, you're not just losing a rate — you're also cashing out whatever equity you've built. A homeowner who rolls $150,000 in equity into the next house is in a completely different position than one starting from scratch.

Why the math isn't as bad as it feels

Chattanooga home prices are only forecast to grow 3 to 5% in 2026. Compare that to the roughly 23% run this market saw a couple of years back — that's over, at least for now. Which means "just wait and let your equity build" isn't doing what it used to do. You're not sitting on some massive upside by holding out another year. Right now, waiting mostly just delays a decision you were going to make anyway.

And here's the part people skip: if you're moving up or sideways in this same market, you're selling high and buying high at the same time. The rate jump stings, no question — but the price gap between your current house and your next one isn't what it was in 2021. You have to run both numbers together, not just stare at the rate by itself.

When selling still wins, even at 7%

I see three situations play out over and over with real clients:

Your life changed and the house doesn't work anymore — new job, growing family, aging parents moving in, a divorce, a remote job that requires you to relocate. That's not a spreadsheet decision, and no interest rate should keep you stuck in a house that doesn't fit your actual life.

You've got enough equity that the new payment stays manageable even at 6.65%. I see this constantly: someone trades a $450,000 house for a $380,000 one — downsizing from East Brainerd or Ooltewah into something smaller in Hixson or Red Bank. Because they're not moving up in price, the new payment barely moves, sometimes close to a wash once the rolled-over equity is factored in.

You're right-sizing down on purpose. Empty nesters, downsizers, people ready to simplify. You're not trading a low payment for a high one — you're trading a big house and a big mortgage for a smaller one altogether, which changes the whole equation in your favor.

The option most people don't know about

If none of those three fit, and what you actually want is access to your equity without touching that low rate at all — more homeowners nationally are taking out a HELOC or second lien instead of refinancing or selling. Your first mortgage stays exactly as it is, rate and all, and you borrow against the equity separately, on top of it. That can fund a renovation, help with a kid's down payment, or even an investment property, without giving up a 3% rate on your primary loan.

To be straight with you: I'm not your lender, and this isn't lending advice. The real numbers on a HELOC depend on your bank, your credit, and your equity position — that's a conversation for a lender. But it's worth knowing the option exists before you assume selling is your only move.

How to find your number

Every path above — selling and buying up, selling and right-sizing down, or keeping your rate and tapping equity another way — comes down to your specific numbers: your rate, your remaining balance, your equity, your target house and its price.

I can't tell you which one is right for you in a blog post, because I don't know your numbers yet. But I can run the real math in about five minutes if you send me your address and your current rate — and I'll tell you honestly whether selling makes sense for you right now, or whether it doesn't. If the math doesn't work yet, I'll tell you that too, and what would need to change.

Text me your address and rate — 423-240-3396.

And if you're on the other side of this — buying at 7% right now and wondering if you made a mistake — that's next week's topic. Watch the video breakdown here.
