What Fannie Mae's 7.5% mortgage forecast actually means for a remodeler, a mover and a spec-home builder

Fannie Mae's economists raised their mortgage-rate forecast sharply on Wednesday. According to CNBC, they now expect the 30-year fixed rate to average 7.4% in the fourth quarter and 7.5% across all of 2027. The previous forecast was 6.8% for the fourth quarter and 6.7% for 2027. A forecast is not a quote, but it tells you which way the people who price housing finance think the next 14 months are heading.

The move already shows in the survey data. Freddie Mac's weekly survey had the 30-year at 6.65% on August 20 and 7.40% on October 8. Over the same stretch the 10-year Treasury yield, which mortgage rates loosely follow, went from 4.79% on September 1 to 5.21% on October 13, per Treasury's own yield curve data. The Fed also raised its target range on September 16, to 3-3/4 to 4 percent, according to its statement.

The number behind the number: what a buyer can qualify for

Everyone quotes the payment. The figure that matters to a trade is the loan size a household can carry, because that sets the price of the house they can bid on. Take a buyer who can afford $2,500 a month in principal and interest on a 30-year loan:

• At 6.65%, that supports a loan of about $389,000.
• At 7.40%, about $361,000.
• At 7.5%, about $358,000.

Same paycheck, about 8% less house, before a single price change. On a $400,000 loan the monthly payment goes from about $2,568 at 6.65% to about $2,770 at 7.40% and $2,797 at 7.5%. Against the old 2027 forecast of 6.7%, the new one is about $216 a month more. CNBC adds that Zillow counted pending sales down 8.5% in September from a year earlier, and that fewer buyers can now qualify at all.

A kitchen and bath remodeler

The remodeler's customers are mostly not buying; they are paying out of savings, a home-equity line or a cash-out refinance. A home-equity line floats off prime, which by the usual convention sits three points above the top of the Fed's range, so 7% today. The effect tends to show up as smaller jobs rather than fewer calls: a $60,000 kitchen quoted in August becomes a $45,000 one in November because the owner is now pricing it against a payment.

Work it through for a crew that finishes eight jobs a month, which is an assumption. If the average ticket shrinks 15%, from $60,000 to $51,000, monthly revenue falls from $480,000 to $408,000. That is a $72,000 gap the overhead does not shrink to meet. We count 141,913 independent construction companies in the CheckThisBiz data.

A moving company

Movers feel closings, not mortgage rates. Pending sales are signed contracts that close in the following weeks, so the drop reaches a mover's calendar with a lag. Assume a crew that books 60 residential jobs a month at an average $2,400, which is $144,000 of revenue. If volume tracks the 8.5% drop in pending sales, that is about five fewer jobs and about $12,240 less revenue a month. Truck payments and insurance do not move with it. The partial offset is commercial and corporate relocations, which do not depend on a household's mortgage and which a mover with a spare crew can go after now. There are about 42,966 independent moving companies in our data, so that work is contested.

A spec-home builder with a construction loan

This is the one with a clock on it. Assume a $500,000 construction loan at prime plus 1.5 points, 8.5%, interest only. That is about $3,542 a month. Each quarter-point the Fed adds costs about $104 a month. The bigger cost is time: a house that sits nine months instead of four carries about $17,700 more interest at the same rate, while buyers who qualify for 8% less loan stay away from the same asking price. The builder's real choice is a price cut now against more carry later, and each extra month of carry is $3,542 that a cut of that size would have saved.

What to actually do

1. Remodeler: quote two tiers on every job and make the smaller one easy to say yes to. Track average ticket weekly, not just lead count.
2. Mover: compare jobs booked for November and December with the same point last year. If it is down more than the 8.5%, you have a pricing or marketing problem on top of a market one.
3. Builder: write down the carry cost per unsold house per month and the price cut that equals three months of it. That is your decision line. If your loan is floating, our construction financing page explains the structures that exist.
4. Nothing of yours reprices and you have no inventory: the right move is to hold, watch the 10-year chart and the Thursday Freddie Mac release, and not discount to chase a market that is not there yet.
