Can't see the property market crashing mate, it may drop a bit but with round here with T5 going on I can only see them going up..............I'm no more than 20 minutes from any of Heathrow, M4, M25, M3, 30 minutes by car to Central London, an hour by public transport..............you're no more than just over an hour away in Essex so you'll be in the same boat.
If you can buy then I would.
