if it is structurally fine (get a building inspection!) then cosmetic things can be fixed easily. My place was horrible when I bought it - still stuck in the 70s, until I could renovate the horrible brown kitchen doors got a coat of paint, the walls got a coat of paint, then I ripped the carpet up in the lounge/dining/kitchen and put down rugs until I could afford to tile it (left ikky carpet in bedrooms). I did a LOT of the renovation in this place - ripped out the kitchen & bathroom, rendered the walls in the bedrooms - then I got professionals in to do the rest including render the walls in the lounge/dining/kitchen and the tiling. I'm in the process right now of repainting the place to freshen it up and to remove all memories of my xh (who picked the last lot of colours).
