Market intelligence for single family rentals

Mainstay is a market intelligence platform built for buying, managing and selling homes in the single family rental industry, turning complex data into clarity that lets participants act with confidence. Single family rental is unusually data-poor for an institutional asset class, because every property is individually priced and no exchange exists — which is exactly why intelligence is the product. Founded within Opendoor and launched as an independent company in 2024, Mainstay recently raised a Series A led by Khosla Ventures.
