cost expenses/taxes for flat in London?

[pstein]

I am interested in buying a small apartment/flat in London.

For that I would get an impression what kind of taxes and expenses I can expect.

Do the taxes depend on the area/burrough or do they depend from the buying price?

Is there a difference between taxes für UK and non-uk (=EU citizens)?

Are there any city fees property owners must have to pay?

Is there a general overview about all these fixed (!) costs?

Thank you
Peter
