I am not quite sure what you mean by property tax - you would be required to pay a council tax on any property you rent or buy this increases depending on the size of the house. Typically though you would expect to pay no more than £1000-£1500 per annum on this. Cost of living is pretty high over here though the average gas/electricity bill is running in the region of £800 per year now. Petrol in 90p per gallon and depending on where you would like to stay - Renting or purchasing would most definitely not be cheap especially if you are planning on staying in London which is vastly overpriced.
