Stop counting on a refinance you might never get. Underwrite the payment you can afford today

The 30-year fixed mortgage averaged 6.55 percent the week of July 16, up from 6.49 percent the week before, per Freddie Mac. Earlier this year it was lower. In between it made a round trip, drifting down and climbing back, while the Federal Reserve sat on its hands the entire time. Anyone who bought this spring on the theory that rates were about to fall is now making the exact payment they told themselves was temporary.

That is the whole case against the most repeated piece of advice in real estate right now. "Marry the house, date the rate" sounds shrewd. As a financial plan it quietly assumes something nobody can promise: that a lower rate is coming, and coming soon enough to matter. Strip that assumption out and the advice collapses into something honest and far less catchy. Buy a payment you can actually afford at 6.55 percent, and treat any future refinance as a bonus you did not need.

Nobody is forecasting the path, including the Fed

Start with why the refinance is not bankable. Thirty-year mortgages do not track the Fed's overnight rate. They track the 10-year Treasury and the risk premium layered on top of it, and both of those move on inflation prints and bond-market nerves that no one predicts reliably. The clearest evidence is the round trip itself: the Fed held steady all year and rates still moved in both directions.

Even the people setting policy are not forecasting a clean path down. The Fed's own June projections showed a committee divided over whether the next move is a hike or a cut, with officials scattered across both sides and only a lone voice penciling in a reduction this year. When the rate-setters cannot agree on direction, a homebuyer betting the household budget on a specific outcome is not planning. They are guessing.

A refinance is not free, and not guaranteed

Say rates do fall. You still have to clear the cost of refinancing, which typically runs a few percent of the loan balance in closing costs. That means the rate has to drop far enough, and stay dropped long enough, to earn back what the refinance costs before it saves you a dollar. A quarter-point dip does not do it. The "just refi later" plan needs a big move, a durable one, and it needs to arrive while you still own the home and still qualify. That is three separate things going right, none of which you control.

Now compare that to the relief you can actually lock in. A seller-paid rate buydown, permanent or temporary, delivers savings the day you close, whether or not a refinance window ever opens. In a market where sellers are handing out concessions on nearly half of sales, that money is often already on the table. The difference is that a buydown is money in hand and a future refinance is a maybe. Build your plan on the one you can hold.

Picture the Florida version of getting this wrong. A buyer stretches to a Fort Lauderdale payment they can only justify by assuming they will refinance within a year. Rates round-trip instead of falling. The refinance never pens out. Now they own the payment they underwrote as temporary, indefinitely, and the cushion they skipped because "it is only for a year" is a cushion they do not have.

The move is to buy the payment, not the promise. Run the numbers at 6.55 percent and ask one question: does this work if the rate never changes? If the answer is no, the house is too expensive, full stop, and no amount of "we will refinance" fixes that. Use a permanent or temporary buydown for relief you can actually count on, keep a cash cushion for the year that does not go to plan, and let a future refinance be the upside you were not relying on. Date the rate if you like. Just do not sign a thirty-year commitment to a payment you can only afford in a future that may not arrive.
