Sometimes the Multiple Listing Service is not the only source for owner carry properties. If you know which park you would like to live in, I could check with agent's representing sellers and find out if they have considering carrying the note. Many times it depends on your down payment. There is also the possibility of lease to own, and equity sharing that may work. If you will e-mail me with your wish list and price range, it may be possible to find owner carry properties that are not listed as such.
