All, Latest research I have seen involves quite negative price growth in many of the traditionally wealthy areas namely central London. Dulwich is considered on this and was the only area which wasn't decreasing, albeit was flat on a 3month basis and up 2% on a 12month basis - not huge but the best across the comparative areas. In terms of non-wealthy areas, east Dulwich still hits a spot where aspiration all young professionals can buy or rent a decent house, so will always be in demand whilst supply across the capital is still restricted and the only thing being built is very high value or soulless purpose built blocks (such as nine elms, where you are quite right prices are dropping and it is mainly foreign buyers. But consider those flats wouldn't have been built without those foreign buyers taking them off plan, and then the domestic market buys them cheap when they sell them on...)
