lalalonglegs I know what you mean about the main roads, though they have knocked down the estate and the school is now a 'co-operative' academy with fairly reasonable results. I wouldn't personally choose the Shooters Hill area but on the other hand, it's a pretty decent-looking 5-bed house overlooking a green space for £340k!
Mintyy, I'm sorry I haven't had as much time to look for you as I might have liked, owing to a work crisis hard on the heels of the very boring meeting.
Still, this looks really lovely (perhaps just my taste!), though I can't help feeling it's a tad overpriced. It'd be a shoo-in for Forest Hill Boys, though, which may be good for you.
This is detached - pretty rare - and has a gigantic hallway (nice for a Christmas tree) but some of the bedrooms look a bit small.
Leftfield alert: this one is completely about the location. It is definitely not a bargain.
Not much going in Brockley; this is best viewed as a project, though it's well inside your budget, so lots left over for renovations.
I was looking forward to this given your fairly generous budget, but there's not a lot out there at all (unless you want to move to East Dulwich, where it seems prices have dropped sufficiently that there are quite a few 4+ bed places within budget). Ask me again in a couple of months!
(Sorry for the derail, heathen, I know nowt about the North!)
