What is the one thing that puts you off renting or buying a house?

I look p many things, kitchens can be redone, gardens, bath room, cupboards too. The main thing is the location. Rather buy a dump in a good area than a mansion in a slum. The dump you can still fix up and then make your money. One thing I do ask is a Borer Beetle Certificate at the coast, as well as a roofing certificate. To replace a roof is very expensive.
