Fannie Mae 2027 Mortgage Forecast Sees 30-Year Rate at 7.5%

Fannie Mae's 2027 mortgage forecast now calls for the 30-year fixed rate to hold near 7.5% all year, a sharp upward revision from the path its economists laid out just three months ago. In the October 2026 Economic and Housing Outlook, published October 12, the agency put the average 30-year rate at 7.4% for the fourth quarter and at 7.5% for every quarter of 2027, versus the 6.8% and 6.7% it forecast in the prior edition, CNBC reported on October 14.

The revision lands on a market that has already repriced. The average 30-year fixed rate stood at 7.46% on Tuesday, October 13, according to Mortgage News Daily, and the September CPI report released October 14 ran hotter than expected, pushing bond yields higher. Fannie Mae's economists now attach the same 5.3% print to the 10-year Treasury for the fourth quarter of 2026 and through all of 2027, per the forecast tables, up from a 4.7% annual average in their prior outlook.

The number that matters to a borrower is the payment. At 7.5%, a $300,000 30-year fixed loan costs about $2,098 a month in principal and interest; at the 6.7% Fannie Mae previously forecast, the same loan ran about $1,936. That is roughly $162 a month, or $1,944 a year, that higher rates now move into interest and out of the buyer's budget, based on a standard amortization of the two rates.

Housing demand was already cooling into this revision. Pending sales, counted by signed contracts on existing homes, were down 8.5% in September year over year, according to Zillow figures cited by CNBC, and mortgage applications have slid to a 21-month low. Fannie Mae's outlook embeds the slowdown: it projects total housing starts of 1.30 million in 2027, below the 1.34 million it expects this year, and sees refinance share of originations falling to 23% from 31%. Total home sales are forecast at 4.71 million in 2027, essentially flat against 2026.

There is a counterargument worth stating. A forecast is a projection, not a lock, and Fannie Mae's economists flagged their own uncertainty, noting the estimates rest on a set of assumptions and are subject to change as the data move. If inflation cools faster than the market now prices, or if the Fed's own October path softens, the rate forecast would follow yields lower. The agency publishes a fresh monthly outlook, so the next read is weeks away rather than a year.

For anyone shopping a mortgage or deciding whether to refinance, the implication is that the low-rate window most forecasters expected for 2027 has narrowed. Fannie Mae's October outlook, built on data through September 30, takes the consensus on the 30-year from a 6.7% average to 7.5%, and it did so the same week a hot CPI print added to the pressure on the long end. The practical move from this report is not a prediction about mortgage rates but a date: the next Fannie Mae outlook, and the October jobs and inflation releases that will feed it, determine whether 7.5% holds or bends.
