Boy what a lot of great answers. There are so many ways to approach this. I've actually created a file called "Sell or Keep Forever" so that I don't have to rethink everything.
1. We've gotten rid of all our lesser performing properties, 3 singles and a duplex
2. We sold an 11 unit for annualized 37% CAGR or IRR per year over 7 years of ownership.
3. We ALMOST sold a 7 unit but it was going to cost around 80K in ACA payback, dep. recapture and cap gain so backed out. Sticking with 5 buildings consisting of 29 units giving us approx 90-120K cash flow per year.
4. I LOVE the idea of some day seller financing a building or two. ESPECIALLY when we hit 60, we can do a 20 year seller financed 5-10% down and really have a nice annuity payment.
5. It really does NOT take much time or energy to manage our buildings as we've been managing these same properties since 2010, year after year. Wife does the leasing, I do the paperwork, our contractors do everything maint. related. I do lots of tasky stuff like hedge trimming, bark mulch, pruning, cobweb removal, stuff that I can do without being tied up all day on a place, but still saves a few grand a year.
Thank you all. Best of luck to you all!
