Late 2018. I got a big income bump in early 2017 and both my partner I and were able to save for a deposit by living frugally for a couple of years. I wouldn't have been able to do it alone though, I think you realistically need two incomes to buy in London.

Deposit it not the problem, it's the disappointing quality of the properties in London that stops me buying. Why spend £700-800k for a 2-3 bedroom place which has finishing like it's £250k flat.
