The rate on an average 30-year fixed rate mortgage (FRM) lifted slightly to 6.72% in the week ending December 20, 2024. The average 15-year FRM inched up to 5.92%.

Watch for FRM rates to generally work their way lower in 2025 as the Fed completes its job to fully stabilize consumer inflation (and job growth) following the pandemic disruption. The FRM rate decrease through 2025 is expected to be followed by a long-term upward trend, which began in 2013 at the outset of a half-cycle with some 30 years of rising rates on all borrowing.

That said, current political interference with the economy may spill over into 2025. That might cause bond investors to drive 10-year T-Notes further up as seen in the past few months. A perception of rising future inflation has hit the bond market, which directly drives up mortgage rates.

In the long term, property sellers suffer from higher FRM rates. Asking prices are primarily supported by the amounts buyers can borrow to fund a purchase. Thus, an increase in the FRM rate forces most sellers to eventually drop prices or exit the market.

As for buyers dependent on purchase-money mortgage funding, they either:

  • reduce their standard of living or investment goals and acquire property in a lower price tier, or,
  • wait out the drop in asking prices until pricing matches their reduced purchasing power, the more likely situation.

Buyers increasingly sense current economic conditions are incompatible with the purchase of over-priced property due to mortgage funding at high rates. The result is more buyers are heading for the sidelines — ready, but not willing or able. However, patient buyers and their agents will, maybe by 2027, discover their situation greatly improving. Watch for-sale inventories to grow, sellers forced to cut prices to unload property they no longer want, and mortgage rates to then lower.

Fundamentally, FRM rates are tied to the 10-year Treasury note market, as are capitalization (cap) rates for setting income property prices. The 30-year FRM rate moves in tandem with the 10-year Treasury note rate, plus the lender’s risk premium of between 1.5% and 3.0%, based on risk of default. Historically, the risk premium spread between the 10-year T-Note rate and the 30-year FRM rate in normal times is 1.5%. The spread is far greater for cap rates.

However, the 10-year T-Note rate was 4.57% on December 20, 2024. Thus, the spread between the 10-year T-Note and 30-year FRM rate is 2.15%, above the historical risk premium spread of 1.5%. Today’s generous spread indicates lenders continue to pad their risk premiums in anticipation of future rate increases — and foreclosures due to defaults.

Average 5/1 adjustable rate mortgage (ARM) rates

The average monthly rate on adjustable rate mortgages (ARMs) is less steady, spiking up to 6.88% on December 19, 2024 after briefly dropping to 6.26% at the start of December following a summerlong trough.

The interest rate on the ARM is higher than the 15-year FRM and 0.16 percentage points lower than the 30-year FRM rate — with the limited advantage of a 30-year ARM not worth the significant forward risks of loss inherent in ARMs. Today, a riskier ARM is rather useless to buyers seeking to increase their borrowing capacity when purchasing low- or mid-tier price homes.

This inversion in ARM rate over the FRM rates has eliminated the appeal of ARMs except in mortgage-financed high-tier housing and commercial property.

The 5/1 average adjustable rate mortgage (ARM) rate shows the average rate for the first five years after origination. After the initial five-year period, the ARM rate is adjusted annually based on an index figure, such as a certain Treasury Bill rate (which reflects Federal Reserve rate movements) or the Secure Overnight Financing Rate (SOFR). The average ARM rate is provided by Freddie Mac’s survey of the Western Region of the U.S.

This index is one of several indices used by lenders as stated in their ARM note to periodically adjust the note’s interest rate. It replaced the LIBOR in 2021, which was found to be manipulated in the years leading up to the 2008 recession and financial crisis. The ARM interest rate equals the SOFR rate plus the lender’s profit margin. The rate is based on overnight borrowing in the U.S. Treasury repo market. The SOFR is produced in a transparent manner and is based on observable transactions, rather than models, and, unlike the LIBOR, is not dependent on bank estimates.
