My wife and I are in the market for a house right now and I was wondering if anyone had advice on specific aspects of a house to look at that that would make you not purchase it.

Examples would be cracks in the walls (direction specific?), furnace brand, window type, age of roof and so on. Obviously we are having a home inspector go through the house we select, but we are still trying to get as much information as possible while veiwing the homes.

Any advice would be appreciated!
