Should I become the bank?

[JW Franz]

I am based in Tampa and own a portfolio of 46 SFH Rentals, all are rehabbed and rented. Most have ARV of $150K. With the prices moving higher I am considering sale of all or part, in the coming year. I am 52 an would like more of an income stream than a lump of taxed cash. Another larger investor suggested I sell the properties and offer self financing, note and mortgage. Does anyone have experience with terms for such? Rates, down payments, terms. I was considering selling the properties at a 10% premium to the ARV, 20 year, 8%, 5% down, 1/2 point. Thoughts? Also, most of the properties are owned without loans, a few have a commercial portfolio loan against them. Has anybody done this? What are some of the gotchas? What are some tax implications?
