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.

Small Balance Lending Surges Through First Half of 2019
Small balance multifamily lending volume in the first half of 2019 totaled $58.5 billion on an annualized basis, representing a 7.9% gain from 2018’s total.
Whether the macroeconomic and real estate cycle continues to lengthen or we begin to see signs of a market correction, we can expect the small balance market to hold steady as lenders continue to maintain conservative underwriting. In the interim, favorable interest rates will elevate refinancing activity, and the sector’s continued maturation and increased agency support will continue to promote liquidity in the space.
