get an agent to represent or at least find a Title company that works with carry backs.
If you would like to contact me through my site at http://RalphandTricia.com I can refer a good Title officer.
Yes, there is a way. If you do not wish to work with an agent I strongly suggest you find a title officer that is experienced with these types of transactions in addition to seeking legal advice regarding the contract. If you would like to email me I will send you the name of a title officer that I have worked with for years in doing seller carrybacks.
Good luck, and be careful.
I can't imagine one real estate professional who would advise you to do this on your own. There are many legal considerations and most real estate agents have never been involved in a seller carry back transaction. Thus a well versed real estate attorney is good advise.
