Why the next Fed decision should not impact your house purchase

The Federal Reserve held its benchmark rate steady at 3.75% to 4% on October 28, but two officials voted for a quarter-point increase, leaving uncertainty about future moves. However, prospective homebuyers should not let small rate changes alone determine whether to purchase, according to analysis in this column.

The Fed does not directly set mortgage rates. Mortgage pricing reflects longer-term borrowing costs, inflation expectations, and mortgage market conditions. A quarter-point Fed increase does not automatically produce a quarter-point increase in a homebuyer's mortgage quote. Once a fixed-rate mortgage closes, later Fed increases do not change its rate.

On a $300,000 loan over 30 years, moving from 7% to 7.5% adds roughly $102 a month to principal-and-interest payments, a 5.1% increase. Freddie Mac's national 30-year average was 7.24% on October 29. A buyer whose budget cannot absorb this difference should reconsider the price or timing. For a financially prepared household, it may be manageable.

The payment math matters less over shorter ownership periods. The National Association of Realtors reported that the typical home seller had owned the property for 11 years. Atlanta Fed researchers described the average mortgage life as around seven to 10 years. If a borrower sells after five years at 7.5% rather than 7%, the additional interest cost would be roughly $7,562.

Refinancing can reduce the impact of higher initial rates. ICE's December 2024 Mortgage Monitor reported that rate-and-term refinancers in September and October had held previous mortgages for an average of just 15 months, though this was an unusually short period during a particular window.

On a $300,000 mortgage at 7%, scheduled payments reduce principal by approximately $17,605 over five years and $48,687 over 11 years without assuming appreciation. For buyers with stable income, adequate reserves, and plans to stay long enough to spread transaction costs, homeownership still offers a practical path to accumulating an asset while meeting housing needs.
