We're putting our flat on the market (it's the ground floor flat in a terraced house that's been converted into 2 flats) the front garden and half the back garden belong to our property, the upstairs neighbour has asked if we'd be interested in selling the front garden to her - has anyone done this? I don't think it would impact the value of the property very much, as the way it's laid out the front garden could just as easily be part of either flat.
Can it be done quickly and easily or would it just be a huge amount of faff and expense for minimal gain while we're trying to sell?
