Ilford seems surprisingly immune to gentrification. Which is odd, because it has decent transport, it's pretty cheap, there's some lovely housing stock, nice green space and a grammar school.
Oh I definitely believe Ilford's time will come - it has a lot going for it. It's just that it's neither hip for young people now, nor safe enough to appeal to affluent families, so there will be slow change rather than a sudden wave of gentrification. Not the worst thing in fact.
