Opendoor Technologies is expanding its platform to simplify home buying and drive transaction volumes. The company has launched Opendoor Checkout in 40 states, integrating mortgage preapproval, free cancellation, early move-in options and warranties into one platform. Opendoor is developing its own mortgage offering to reduce reliance on third-party providers and improve conversion rates. For sellers, the company introduced a Cash Plus guarantee allowing transaction reversals for a small restocking fee. In Q4 2025, Opendoor reported improvements in resale velocity and buyer experience. By combining buying, selling and financing services, the company aims to increase transaction volumes whilst improving efficiency. Opendoor faces competition from Zillow Group, which influences digital real estate through its Premier Agent network, and Offerpad Solutions, which operates with a localised iBuying strategy focused on pricing spreads and operational control.
Opendoor is acquiring Doma's closing and escrow business to reduce mortgage refinancing costs, the companies told CNBC exclusively. Doma uses machine learning and AI to automate title searches and real estate closings. Terms were not disclosed. Since 2024, Doma's technology has been used in a Fannie Mae pilot programme that eliminates lender's title insurance requirements for about 80% of eligible low-risk refinance transactions. The programme was recently extended through 2027. However, closing costs beyond title insurance remain largely manual and expensive. Opendoor's technology can handle closings more efficiently and at lower prices than industry averages. Following the acquisition, 85 Doma employees will join Opendoor. The deal aims to save borrowers around $1,100 per refinance whilst maintaining zero defects.
