Give Up Your 3% Mortgage to Move in Orcutt? Run the Math
Should I give up my 3% mortgage to move now that rates are over 7%?
It depends on which direction you’re moving. If you’re moving up in price, trading a 3% loan for a 7.4% loan can add $2,500 or more to your monthly payment, so the move needs a strong reason behind it. If you’re downsizing, the equity you’ve built in Santa Maria or Orcutt can shrink your new loan enough that your payment stays flat or even drops, despite the higher rate. The deciding numbers are your equity, the price of your next home, and how long you plan to stay.

If you bought or refinanced in 2020 or 2021, you probably have a rate that starts with a 2 or a 3. And you probably feel a little trapped by it.
You’re not alone. More than half of all U.S. mortgages carry a rate at or below 4%, and about 1 in 5 are below 3%. Industry writers have a name for it — the “golden handcuffs.”
But here’s what I tell every homeowner who asks me this: the rate is only one number. Your equity, your next home’s price, and your property taxes matter just as much. Sometimes the math says stay. Sometimes it says the move costs far less than you feared.
With the 30-year fixed averaging 7.4% in mid-October — the highest since late 2023 — here’s how to run it for your own situation.
Moving up vs. downsizing: two very different answers
Let’s use a realistic Orcutt example. You bought in 2021 and have a $520,000 loan at 3%. Your principal and interest payment is about $2,192 a month. Your home is now worth about $1,000,000, and after paying off your loan and selling costs, you’d walk away with roughly $490,000.
Scenario 1: Moving up to a $1,200,000 home
You put $500,000 down (your equity plus a little savings) and borrow $700,000 at 7.4%.
- New principal and interest: about $4,847/month
- Increase over today: about $2,655/month
- Property taxes reset to the new purchase price — roughly $1,100/month at about 1.1%, compared to what you pay now on your older assessed value
That’s a real jump — often $3,000 or more a month once taxes are included. It can absolutely still be the right move, but it needs a reason that’s worth that cost: more space you’ll use every day, a job change, family moving in, or a home you plan to stay in for the long haul.
Scenario 2: Downsizing to a $750,000 home
You put about $450,000 down and borrow $300,000 at 7.4%.
- New principal and interest: about $2,077/month
- Change from today: about $115 less per month
Read that again. Even at 7.4%, the smaller loan can cost less than your 3% loan does now. That’s the power of the equity you’ve built.
If you’re 55 or older, the property tax side can work in your favor too (more on that below).
This is the scenario I see homeowners overlook most often. They assume a 7% rate makes any move unaffordable, when the math says otherwise. If you’ve been thinking about it, my post on why moving to a smaller home after retirement makes life easier covers the lifestyle side.
The costs beyond the rate
Your payment isn’t the only number that changes when you move. Plan for these too.
Selling costs. Commissions, escrow, the owner’s title policy, and Santa Barbara County’s transfer tax of $1.10 per $1,000 typically take 5.5–8% of your sale price. I broke down every line item in what it costs to sell a home in Santa Maria and Orcutt.
Buying costs. Expect roughly 2–5% of your purchase price in buyer closing costs, plus moving.
Property taxes. In California, your tax bill is based on your purchase price, not your neighbor’s. A long-time owner paying taxes on a much lower assessed value will see that reset when they buy — unless an exception applies.
Prop 19 for homeowners 55 and older. If you’re 55 or older (or severely disabled), California’s Prop 19 lets you transfer your existing property tax base to a replacement primary home anywhere in the state, up to three times. You have two years between selling and buying, in either order. If the new home costs more, the difference is added to your base rather than starting over. The rules and filing deadlines are strict, so confirm with the Santa Barbara County Assessor or a tax professional before you count on it.
The refinance “maybe.” Some buyers plan to refinance later if rates drop. That can work, but it isn’t guaranteed, and refinancing has its own closing costs. Make sure the payment works today — treat any future refinance as a bonus.
When moving makes sense — and when staying does
Here’s the framework I walk my clients through.
Moving usually makes sense when:
- You’re downsizing and your equity can cover a large down payment
- Your life has changed — a new job, a growing or shrinking household, a need for single-level living
- You plan to stay in the next home for years, so the selling and buying costs spread out over time
- The home no longer fits, and renovating would cost more than the move
Staying usually makes sense when:
- The move is lateral — similar size and price, mostly to “start fresh”
- You can solve the problem in place, like adding a bathroom or an ADU
- The main motivation is market anxiety, not a real change in what you need
- You’d be stretching your budget to make the new payment work
One more option: if you’re worried about timing two transactions, ask about buying contingent on your sale, a rent-back after closing, or bridge financing. Each has trade-offs, but none of them requires you to choose between being homeless and carrying two mortgages.
It’s also worth knowing that the “right” rate to move is personal. I wrote about that question back in 2024 in what mortgage rate do you need to move? — the principle still holds, even though rates have moved since then.
How to run your own numbers
You need four things to know whether moving makes sense:
- What your home will sell for today — not a Zestimate, but a realistic price based on recent sales in your neighborhood
- Your current loan balance and payment
- The price range of the home you’d buy next
- Your new payment at today’s rate — your lender can give you this in a few minutes
Subtract your current payment from the new one. That’s the monthly cost of moving. Then decide whether what you gain is worth that number.
The first number is the one most people guess at, and it’s the one that changes everything else.
Frequently Asked Questions
Is it smart to give up a 3% mortgage rate?
It can be. Moving up in price usually raises your payment significantly at today’s rates, so the move needs a strong reason. Downsizing often keeps your payment flat or lower because your equity shrinks the new loan.
How much will my payment go up if I sell and buy at 7%?
It depends on your equity and your next home’s price. In one Orcutt example, moving from a $520,000 loan at 3% to a $700,000 loan at 7.4% raised principal and interest by about $2,655 a month. Downsizing to a $300,000 loan at 7.4% cut it by about $115.
Can I keep my low property taxes if I move in California?
If you’re 55 or older, severely disabled, or a disaster victim, Prop 19 lets you transfer your property tax base to a replacement primary residence anywhere in California, up to three times for those 55 and older. The move must happen within two years, and you’ll need to file a claim with the county assessor.
Should I wait for mortgage rates to drop before selling?
Waiting can make sense if you have no urgent reason to move. But rates aren’t guaranteed to fall, and prices can rise while you wait. If your needs have already changed, run the numbers now rather than guessing.
Can I transfer my low-rate mortgage to my new home?
Generally no. Most conventional loans can’t be moved to a new property. Some FHA and VA loans are assumable by a buyer of your current home, which can be a selling point, but that doesn’t carry the rate to your next home.
The bottom line
A 3% mortgage is worth protecting, but it shouldn’t keep you in a home that no longer fits your life. Moving up at 7.4% has a real monthly cost. Downsizing often costs far less than you’d expect — and sometimes nothing at all.
