More would-be buyers are choosing rentals as elevated borrowing costs make the monthly payment harder to clear.

The Zillow September rent report, published by Zillow Research on October 15, 2026, says housing demand is finding a new home in rentals, with rentals up 19.2%. Zillow’s summary ties the shift to elevated borrowing costs that are pushing up the monthly payment for would-be homebuyers.

For mortgage professionals, the practical read is straightforward: some purchase shoppers are not disappearing, but they are delaying ownership or choosing to rent for now. That changes how loan officers should talk about affordability, timing, credit readiness, and the long follow-up window between a first preapproval conversation and an eventual purchase.
