Need a company that collects monthly payments from buyers who have seller financing

[Sylvia Castellanos]

I am interested in selling vacant lots to buyers using seller financing, in other words, covering most of the purchase price myself.  I know people who sell a lot of properties based on that use specialized companies to collect the monthly payments and deal with buyers who are defaulting on their obligation.  That is definitely the route I want to go. How do I find companies that perform that service?  Also, does the company  have to be in the same state  as the property, or can I use a national company?  I will really appreciate feedback on this. I have googled it using every search term I could think of, but I have come up with nothing.
