Financing a Build-to-Rent Community Through Construction, Lease-Up, and Stabilization

Single-family rentals (SFR) now house 41% of the U.S. renter population, according to Rentometer Mid-Year Report 2025: National Trends in Single-Family Rental Markets. Arbor provides investors with short-term and long-term SFR financing to meet this growing demand. Whether a sponsor is developing a build-to-rent (BTR) community, holding an SFR portfolio long-term, or acquiring assets to rehab, Arbor finances build-to-rent (BTR) communities across construction, lease-up, and stabilization under one lender relationship, backed by the strength of an $802 million BTR collateralized loan obligation Arbor closed in May 2025.
