I Have a 3% Mortgage. Should I Still Sell My San Diego Home?

If you locked in a mortgage rate near 3% during the years when that was normal, moving now can feel like giving up money you already won. That reaction is understandable, and it is also not the whole picture. Whether selling still makes sense depends on why you want to move, what the math actually looks like on the new payment, and which of a few specific strategies you use to bridge the gap. Here are four real scenarios.

Why rate lock-in feels so heavy right now

With Freddie Mac's 30-year average sitting at 6.95% as of mid-September, a 19-month high following the Federal Reserve's September rate increase, trading a 3% rate for something in the high-6% to low-7% range can add well over a thousand dollars a month on a comparable loan amount. That is a real number, not an abstraction, and it is the entire reason "just sell and buy something better" feels riskier than it used to. The question worth asking is not whether the new payment is higher. It almost certainly is. The question is whether the reason for moving is worth that specific number, and whether a specific strategy can soften it.

Scenario 1: You need more space and are not moving by choice

Growing families, a new job requiring relocation, or a life change that genuinely requires a different home are the clearest cases for moving despite the rate. Here, the useful move is modeling the actual new payment with the San Diego mortgage payment calculator, so the decision is based on a real number rather than dread of an unknown one. Sometimes the gap is smaller than feared once a larger down payment from existing equity is factored in.

Scenario 2: You want to move but could genuinely stay

If the motivation is more "it would be nice" than "we need to," this is where the math should carry real weight. Run your current home's likely sale proceeds, the new home's likely payment, and compare that honestly against staying and, if needed, renovating or refinancing a portion of existing equity instead. There is no universal right answer here, only an honest one specific to your numbers.

Scenario 3: You want to buy before you sell

This is the scenario that trips up the most sellers, because it can feel like you need to solve two problems at once. Three structures handle it:

A bridge loan, secured against your current home's equity, gives you access to cash for a new down payment before your existing home sells, though it typically costs more than a standard mortgage and is meant to be short-term.

A home equity line of credit on your current home can serve a similar purpose, often at a lower cost than a bridge loan, if you have enough equity and time to set it up before you need it.

A contingent offer, where your purchase depends on your current home selling, avoids extra financing costs entirely but can make your offer less competitive in a market where sellers are still favoring clean, non-contingent terms in many pockets.

Scenario 4: You want to sell but you're worried buyers can't afford your home at today's rates

This is where you, as the seller, have more use than it might feel like. A seller credit toward closing costs or a rate buydown can make your home's effective monthly payment meaningfully more attractive to a payment-sensitive buyer, often without cutting your net proceeds as much as an equivalent price reduction would. With 22.3% of active San Diego County listings currently carrying a price reduction, offering a credit instead of chasing the price down can be the difference between sitting on the market and closing on your timeline.

What to do if your home sits longer than expected

It is not unusual right now. Pending sales in San Diego County were down 13% year over year in August even as inventory stayed limited, meaning buyers are pickier, not absent. If your home passes 21 to 28 days, roughly the current county median, without an offer, the right response is a pricing and marketing review against recent closed comparables and honest feedback from showings, not an open-ended wait or a panic-driven price cut.

Frequently asked questions

How does buying before selling work in San Diego?

Typically through a bridge loan against your current home's equity, a home equity line of credit used as a short-term down payment source, or a contingent offer where the purchase depends on your current home selling. Each has different cost and risk tradeoffs worth reviewing with a lender before choosing.

What is a bridge loan for buying a new home?

A short-term loan secured by your current home's equity that lets you access cash for a down payment on a new home before your existing home sells. It is typically more expensive than a standard mortgage and meant to be repaid quickly once the sale closes.

Can a seller credit help buyers afford my home?

Yes. Offering a credit toward closing costs or a rate buydown can make your home's effective monthly payment more attractive to buyers who are payment-sensitive at today's rates, sometimes without lowering your net price as much as a straight price cut would.

What happens if my San Diego home doesn't sell in the first few weeks?

It is not unusual in the current market, since pending sales have softened even where inventory remains limited. The right response is usually a pricing and marketing review rather than panic: confirm the price against recent closed comparables, check feedback from showings, and consider a targeted adjustment rather than an open-ended wait.
