Sorry if this is going to be stating the obvious but I really can't get my head around what I have to do. I've googled it and really am none the wiser.
STBXH and I bought a flat together which is currently rented out and I am going to move back in and buy him out. Approximate figures, we bought it for £160k, recently valued at £280k, outstanding mortgage of £145k. How much will it cost me to buy him out?
