@Morgan Carmichael, if you want a list of foreclosures, don't pay for it. Have your local agent set up an automatic search for those foreclosures in the MLS. The law requires banks to use licensed real estate agents to sell bank owned properties, so they will be in the MLS. If you are looking for pre foreclosure properties, that is a different ball game. You need to then be looking for properties that have already been assigned a trustee. How to find out this info varies from county to county and state to state. For example, Jackson County, Missouri has a publication that you can pay for to get this list. Sometimes you can search the online county records for this information.
In addition, I believe it is required by all states that the individual counties must publish (in a public publication) the list of all properties that will be auctioned off on the courthouse steps (this would include all foreclosures). I know this is true in Missouri, but I am not 100% sure it is required in Kansas or the rest of the country. In Clay County Missouri, for example, all of these listings are published in the Kearney Newspaper.
Before you pay some national company for this information, I would give your local county assessor a call and see what they recommend.
