It looks like we have missed the boat in SE London. We were set on South Norwood as it was relatively cheap, compared to the rest of SE London, but even that is looking unaffordable for us. We can stretch to £240k max and have 2 DC so we will need to consider primary schools in a couple of years. We need to stay in London for DP's job so as much as I'm tempted, it's not really an option.
We only know the Grangewood Park area and it looks nice enough. Does anyone live in Thornton Heath with young DC? Is there a reason it's cheap or can someone be wonderfully reassuring and tell me it's going to be ok?
