Single-Family Rental (SFR) has transitioned from a fragmented, “scattered-site” experimental niche to a mature, institutional-grade core asset class. As of 2026, the sector is defined by its resilience, professionalized management, and a structural repricing that has enhanced its yield profile relative to traditional multifamily. The core thesis for 2026 is simple: constrained supply meets aging demographic demand, creating a durable yield floor unseen in urban multifamily hubs.
