After the volatility of 2022–2024, mortgage rates have settled into a more predictable range of 6.0–6.75% for a 30-year fixed conventional loan. The Federal Reserve has signaled it's done hiking rates, and most economists expect modest decreases through 2026.
This creates a nuanced picture for refinancing. If you bought or refinanced in 2020–2021 at 2.5–3.5%, refinancing now would increase your rate. But if you purchased in 2023–2024 at 7–8%, refinancing now could save you significantly.
