Mortgage and refinance interest rates today, December 4, 2025: An outlook for rates to remain stable through 2026

Mortgage rates edged lower this week: Freddie Mac's average 30-year fixed rate fell four basis points to 6.19% and the 15-year to 5.44% (down seven basis points), while Zillow's national averages show a 30-year purchase rate near 6.00% and a 30-year refinance around 6.15%. Realtor.com expects the 30-year rate to hover near 6.3% through 2026 as slowing growth and the end of Fed quantitative tightening counterbalance rising U.S. government debt and transitory inflationary pressures, suggesting limited near-term relief for affordability and constrained incentive for widespread refinancing activity.

Analysis

Freddie Mac reports the average 30-year fixed mortgage rate fell four basis points to 6.19% this week while the 15-year fixed rate declined seven basis points to 5.44%; Zillow's national purchase-rate snapshot shows a 30-year at roughly 6.00% and a 30-year refinance average near 6.15%, with 5/1 and 7/1 ARMs at 6.14% and 6.07% respectively. Realtor.com's outlook expects the 30-year rate to remain near 6.3% through 2026, attributing the steadiness to slowing economic growth and the end of the Fed's quantitative tightening offsetting rising U.S. government debt and transitory inflationary pressure. The article emphasizes practical borrower levers — lender shopping, higher credit scores, lower DTI and larger down payments — and notes refinance rates can be higher than purchase rates, with HMDA data pointing to Bank of America and Citibank among lenders with lower median rates. Market signals attached to the piece are mildly negative and cautious with a modest market-impact score, implying limited near-term upside for housing demand and constrained refinancing activity until materially lower rates or policy shifts emerge.

Key Decisions for Investors

• Delay refinancing unless you can reduce your rate by at least 1 percentage point (preferably closer to 2 points) given current refinance averages near 6.15%,
• Shop multiple lenders and prioritize improving credit score and DTI before locking a mortgage because HMDA shows banks such as Bank of America and Citibank have had lower median rates,
• Adopt a cautious stance on mortgage-sensitive equities, homebuilders and RMBS exposure since Realtor.com's 6.3% through-2026 forecast implies limited affordability relief and muted demand,
• If your time horizon is short (within the ARM introductory period), consider a 5/1 or 7/1 ARM as their initial rates (about 6.14% and 6.07%) can be competitive versus fixed 30-year offers
