Hope this is not too off topic...

I am considering moving to UK next fall/winter with my family (wife and 2 pre-school children) for a career move (I am in the IT field). This is just a little more than a thought right now, but I have started my investigations.

I have one question for all the people living there. Suppose I buy a house which is advertised for 200.000. How much taxes should I expect to pay? Any other hidden fees, like commissions, etc...? Also, are there any yearly taxes on the house?

I am trying to understand which is the total cost of buying and ownership, and decide whether the move would be financially sound or not. If it matters, I am considering West Sussex (Crawley) and Surrey, to commute to central London in less than 1 hour. If you have any other suggestion, I would be glad to hear.
