If you're trying to flip a house, the good news is that something like 1 out of every 2 listings right now are short sales are foreclosures. If you want to flip a house, and have some patience, I'd recommend buying a short sale.
I purchased one 2 years ago for well less than what it was worth at the time--my realtor didn't even want to put in my offer because she felt it was too low and the bank wouldn't accept it. Well, I put it in anyway and as the months passed forgot about it. A few months later got a call and the bank accepted.
The house was only 10 years old, but neglected. The former owner (a single mom) didn't do any maintenance at all, and let the place go. fixtures where mixed and matched. Kitchen cabinets were dated, poorly layed out and had water damage from the dishwasher.
I removed all the carpeting and old tile, and put a nicer tile diagonally throughout the lower level (900 sq/ft worth of tile).
Replaced all receptacles and light swtiched.
Gutted kitchen, new cabinets ($12K) new stainless appliances, added an island with eating area, granite countertops, added decorative pendulum-type lights above island.
Got rid of a ceiling fan in living room and added 6 recessed lights on a dimmer.
All carpeting in the house was replaced.
Gutted 1 bathroom and 1 half-bath
In the master bath I added a walk in shower stall (all tiled) with custom framless glass doors. Replaced all fixtures and the vanity. New tile on floors in both bathrooms.
(it had another bathroom but that one was pretty nice so I left it alone, only replaced the light fixtures).
Landscaping was also key, as this house had a pool (which was inoperable and covered when the bank had it on the market). Turns out the pool was only 5 years old and had a busted skimmer pipe which I fixed and now looks brand new.
Had no grass, it was all dirt and weeds, so I added sod and had the driveway redone and widened (a friend owed me a favor, so his company did the driveway).
In all, it took me 3-1/2 months. I think the key is finding the best deal on materials (which doesn't mean using cheap materials) and doing most of the work yourself if possible.
I made about $55K profit off of this house--mostly thanks to the bank taking a loss on this house when they sold it to me. I guess the figured getting some money for it was better then getting nothing when the woman who owned it eventually foreclosed.
