When you buy foreclosed homes the most important thing is that you research the house. Try and see if you can get inside of the home before it goes to auction. This will allow you to have a good idea of how much the home will cost you if there are repairs that need to be done. Add the repairs to the cost of the home so you know what the home really is going to cost you. A professional inspection is the best but if you cannot do this make sure you get inside and out to verify everything that needs to be repaired. Even include small items on this list so you know you are close to being exact with the cost of the home.
When you buy foreclosed homes you also need to consider the price. Verify that the price of the home is a fair value. Compare homes in the area and see if it is overpriced. Some foreclosures are way overpriced because the homeowner bought the home when they were worth huge amounts. For example, a homeowner buys a home at $500,000 and the market flips like it is and the home is only worth $250,000. The homeowner's interest rate has doubled and they can no longer afford their changing interest payments. The bank is going to try to get as close to what the homeowner owes on their loan and not the $250,000 value. Make sure you are getting the value and not what the person owes.
