anything south of the river, you won't get a cab to take you there
but you've got a decent budget so look for an older property that's in the br postcode areas than the se ones, you are outside of london so you don't get london tax on everything, plus the commute shouldn't be that bad and you won't get council scum moving ni next door to you
it's a bit boring though
if you want to buy north of the river you'll get less for more money, and don't even think about buying in the west, the east end prices are going to go up as the olympics draw closer so theres that to consider as well
your budget will get you a good sized 4 bed from what i've seen them go for,
