Sorry about the doom and gloom, but you have asked - East Ham comes under East London and not really the suburbs. Transport costs are very expensive, but you would not be able to drive to work due to the daily congestion charge of 8 pounds per day plus parking which is out of the question.
Don't forget the horrible council tax that every property has to pay and this is NOT included in the rent. This is always payable by the residents of the house
Council Tax 2007-2008
I would think that every single property in East Ham comes under bands G & H. These figures are expected to go up a lot because East Ham is situated within the Olympic games 2012 area.
As has already been posted
Find properties to buy, homes to rent, overseas houses and new homes on rightmove.co.uk is an excellent site. It covers all estate agents all over the country and abroad.
I'm not sure whether you have to pay income tax, but if you do, you might find that you fall in the top band of 40% (it was 50,000 pounds a year, but it might have changed).
I hope this helps and it hasn't depressed you too much.
Good luck with your move.
