Should I sell my house if I have a 3% mortgage?

Short answer: a 3% mortgage is a reason to run the numbers carefully, not a reason to stay put by default. The rate is one input in the decision. The house that no longer fits your life, the equity sitting locked inside it, and the cost of the sale itself are the other three — and one of those four is the only one you actually control.

The "golden handcuffs" are real, but they measure the wrong thing

If you locked a rate around 3% before 2022, every mortgage quote since has felt like an insult. Economists call the result the lock-in effect: homeowners staying in houses they have outgrown because the financing they have feels too good to give up. Ask around and you will find people commuting two hours, living one bathroom short, or keeping a house two sizes too big, all to protect a rate.

Here is what that framing misses: the rate protects your payment, not your life. The honest comparison is not "3% versus 6.5%." It is the total cost of staying in the wrong house versus the total cost of moving — and the cost of moving has a piece most people treat as fixed when it is not.

The real math, in plain terms

Take a homeowner with a $400,000 balance at 3%. Moving to a similar loan at 6.5% costs roughly $14,000 a year in extra interest at the start. Real money. Now put the other side on the scale:

• What staying costs. The second commute hour, the renovation you would need to make the house work, the years of waiting for a rate that may not come back. These are real costs even though no one sends you a bill for them.

• What your equity is doing. If your home has appreciated, you may be sitting on hundreds of thousands of dollars earning nothing for your next chapter. Selling unlocks it for the bigger down payment that shrinks the new loan — which shrinks the rate problem itself.

• What the sale costs — the lever you control. On a $600,000 sale, a traditional 6% commission is about $36,000. At locqube, the same sale is $11,940 with a dedicated agent at 1.99%, or a flat $899 if you run the sale yourself on our platform. That difference — roughly $24,000 to $35,000 — covers one to two years of the higher-rate penalty on its own. The commission is the one number in this whole decision you can change with a single choice.

When staying genuinely wins

Sometimes the handcuffs are just a good deal. Staying usually wins when the house still fits your life, when you would buy in the same market you are selling in with little equity to redeploy, or when the move itself is optional and small. If the only reason to move is restlessness, a 3% mortgage is a fine reason to wait.

When selling wins

Selling tends to win when life has actually changed: the job moved, the family grew or shrank, the stairs stopped making sense, or the equity in this house is the down payment on the right one. It also wins more often than people expect when they price the sale honestly — because the biggest "cost of moving" most homeowners picture includes a commission number that is no longer mandatory.

What about renting it out and keeping the rate?

It works for some people, and it is honest work. You keep the 3% loan and someone else pays it down. But go in clear-eyed: you become a landlord, with vacancies, repairs at midnight, New York and Connecticut tenant law, and taxes on the rental income. If you need the equity out for your next home, renting does not release it. Run it as a business decision, not as a way to avoid making one.

Questions sellers ask

Do I lose my low rate if I sell?
Yes — the rate belongs to the loan, and the loan is paid off at closing. A small number of government-backed loans are assumable by a buyer, which can even make your listing more attractive. Your attorney or servicer can tell you if yours qualifies.

How do I find out what my equity actually is?
Start with what the house would sell for today, based on recorded sales around it — not a guess. Subtract your payoff and the cost of the sale. That last number changes meaningfully at 1.99% or $899 flat instead of 6%.
