Live dashboard — updated nightly across all London boroughs

As landlords exit the market post Renters' Rights Act, motivated sellers are emerging across London. DevSource shows you which sites are moving — before anyone else does.

01
What a refused application really means.
A planning refusal doesn't end a site's story — it often starts it. Owners become motivated. Sites become available. DevSource tracks every one.
02
The signal most developers walk past every week.
A company can cease to exist and still own a building. The asset doesn't dissolve with it. DevSource finds these sites and tells you who to call.
03
From signal to outreach in under 60 seconds.
Every flagged site comes with a brief — the situation, the signal, and exactly what to do next. One click. Ready to send.

Most people who try it don't cancel.
