Which would you choose? Schools aren't an issue but will probably be using Norwood Junction rail for East London Line but Selhurst/T. Heath would be good for access to Victoria.
Looking in the up to £200k maxxximum so not the swish end of the market.
What are the areas like - are there any subtle differences between say the Portland Road end of Norwood Jnct and Thornton Heath especially around the Crystal Palace football ground - are there any major issues concerning transport, after dark life, supermarkets, crime etc that would make you choose one over the other?
