Thanks for that, we've looked at Purley so it's depressing to see your research. It's frustrating, prices seemed doable a few years back when we started saving but just seem to be slipping further out of reach.
My partner works up Purley Way and I commute into Victoria so it was a good location for us.
The places we look at now are getting further and further from the stations. A 10min walk becomes a 10min bike ride to maybe I have to get a bus to the station.
