Seller Financing Agreement/Deed - what to include?

[Cheryl Foster]

What are your favorite items to include on a seller financing agreement &/or deed, to protect your investment, while still giving new buyers enough freedom to improve the property and develop their business on it? Re: selling single-family residential homes for seller financing, as well as my current deal in-process - selling my mixed-use commercial property in rural southeast TN, in a tourist area, to a well-vetted prospective buyer. Land is unrestricted & unzoned; county is easy to work with, to build whatever one wishes. My attorney has defined many items on the draft purchase agreement and deed (both parties looking at draft now). Interested in your thoughts. What were you glad you included in your seller financing? Or what would you include?
