Opendoor + Roam: Expanding Access to Assumable Mortgages

Opendoor Technologies has entered a formal partnership with Roam to identify and support home sales with assumable low-rate mortgages on Opendoor’s national platform. In this partnership announced today, Opendoor will surface listings with assumable notes and route qualified buyers and sellers to Roam’s end-to-end assumption workflow, which coordinates buyer qualification, servicer engagement, and closing support. 

Why this partnership matters

With mortgage rates still elevated versus pandemic lows, the pool of owners holding FHA/VA/USDA loans at sub-market coupons is a meaningful affordability lever. A recent Financial Times analysis estimates that about 23% of outstanding U.S. mortgages are assumable, and roughly 6.8 million carry rates at or below 4%. By embedding Roam’s infrastructure, Opendoor is turning those low-rate notes into an actionable, searchable feature that can influence buyer absorption and listing outcomes.

Historically, assumptions have been underused due to servicer processing delays and document complexity that stall files. Opendoor’s integration is designed to reduce that friction: qualified shoppers can discover assumable opportunities inside Opendoor’s marketplace and move through Roam’s standardized process for underwriting, servicer coordination, and closing.

Company & Capital Context

Roam was founded in 2023 by Raunaq Singh, previously a product lead at Opendoor’s mortgage unit. In April 2025, Roam closed an $11.5 million Series A led by Khosla Ventures’ Keith Rabois, with participation from Opendoor’s Founders and Board Members Keith Rabois and Eric Wu. 

What to Watch (for Agents & Teams)

• Equity gaps: Buyers may need to bridge the difference between the sale price and the remaining first-lien balance. Roam has promoted a second-lien option, Roam Boost, to help cover that gap.
• Servicer throughput: Assumption cycle times still vary by servicer, which can influence contract timelines. 
• Program specifics: VA entitlement restoration, FHA insurance treatment, and eligibility nuances require deal-by-deal diligence.

Industry Signal

The Opendoor–Roam partnership signals that large consumer platforms are embedding financing strategy into listing and search, not just logistics. Expect more listings to highlight assumable loans and more buyers to ask about them. For practitioners, building a standard practice around screening for assumability and preparing clients for the assumption-and-servicer workflow can be a competitive edge as this channel scales.
