Foreclosures, once completed through the entire process, are listed with a local REALTOR and put into the MLS for maximum exposure. The bank wants the most amount of exposure for top dollar. We are seeing less of these on the market than we have in the past and usually banks are brining them up to a retail condition to sell them in most cases to get top dollar for them.
You can ask an a buyers agent for a list of homes that are in Foreclosure. The listing information on the home will say if the home is a Foreclosed home.
If you are hoping to buy a house, you likely have a budget in mind. Hopefully, that budget includes fees that come with the process, not just the purchase price. The good news for buyers is that they aren't directly responsible for paying their agent. Agent fees usually fall on the seller.
