Is this a question or an incomplete statement? Like any small business, there are start up costs. Foreclosures have slowed down but will not completely disappear. The best thing to do is go on different bank websites as well as http://www.hudhomestore.com/Home/Index.aspx.
You can get on their approved vendor list and get work that way. In most cases you will have to have a business license and potentially any other contractor license the banks will require. The biggest expense may be the vehicle you will use to remove all the debris left behind, dump fees as well fuel costs, insurance and other expenses to operate the same. Other than that it takes persistency and hard work to get the jobs. Other ideas that may be helpful are: Foreclosures are not the only properties that need cleaning. When builders complete their construction projects, they need cleaning (detailing) to bring to market. Also any construction site whether residential or commercial will have debris that needs to be removed. Primarily, do not be discouraged and move forward.
