Deal sourcing across portals
Continuously scans Rightmove, Zoopla, OnTheMarket, and auction listings for matches to your criteria.
Coming soon · For property investors and deal sourcers
The deal you’d have found at midnight. Found for you by breakfast.
YieldKey Source scans the market, surfaces off-market opportunities matched to your investment criteria, scores deals on yield and condition, and runs first-contact outreach, so your time goes into closing, not searching. Built by property investors who got tired of trawling Rightmove at midnight.

Built inside our own deal-sourcing operation
We built this for ourselves first.
YieldKey Source started inside Infinity Stays, where we source investment deals for ourselves and a small group of investor partners. We were spending evenings on Rightmove instead of structuring offers. Source replaced that work. Now we’re opening it up to other investors who want the same edge.
Infinity StaysTested inside since 2025
Waitlist
First in line when Source launches.
When is it launching? The waitlist hears first, and we won’t announce a date until it’s real. Waitlist members get early access and founder pricing.
