Someone I've known since 1978 bought a 1 bedroom apartment in 1984 for £19000 and its very tiny in Du Cane Court off Balham High St south London, it's now worth approx, £360,000. To me that is a good investment!
Prime area less than 5 minutes from the tube.
I've just put my Parents ex council 3 bed Maisonette on the market in SW9 for £475,000. The worlds gone mad no wonder youngsters are being forced outside the M25.
