In recent months, mortgage rates have slipped from 7.04% in January to around 6.30%, sparking renewed discussion about whether lower borrowing costs will unlock more demand. ResiClub’s 25-year analysis reveals wide swings in buyer sensitivity to mortgage rates, depending on the housing cycle. In some periods, demographics and credit standards mattered more. In others, rates barely moved the needle. But in the current post-pandemic cycle, mortgage rates have emerged as the dominant force shaping demand.

Today’s heightened rate sensitivity means even small shifts in mortgage rates can have a significant impact on demand. A modest drop may draw buyers back, while a sharp increase could push them out just as quickly. Case in point: when the average 30-year fixed rate hit its 2025 low of 6.26% two weeks ago, purchase applications jumped to their highest level of the year.
