I own a studio flat at present, but I used toown a one bed here in 90s. I think it is very common for extra charges...I would count on having to pay some charges every year and not small amounts.

What you get for your money with service charges is a resident full time caretaker (this one is so helpful and kind, I cant speak highly enough of him). You dont get garage or parking (it is in the street), but I believe you can lease a garage.

Although you end up with extra charges the building is in good order. I love the bulding although at moment I am letting out my studio, as i am living in Australia most of the time adn i need the money.
