Also had to replace fuse panels to make it work - going back and forth with the city was dificult.

That buyer didn't close and they came back to me and offered $197,000 price. 

IF you plan on going back someday, and this is the home you want to move back to, then renting it would be a good idea as long as you estimate that it will cover itself, or preferably, cash flow, which it appears that yours will at @ $2K or so per month (after expenses). 

I started back when they were in Beta mode and free so I've seen them grow quite a bit.

That kind backs out to 12-15% cash on cash return. 

I appreciate your plan to do 1031 and get back into the game.

Based on the knowledge and experience you have, would you consider this strategy if you had to go back at my age?

Traditional + Seller back financing How did you add value to the deal?

It’s on 5 acres and there’s a small pondhouse ADU at the back of the property.

I can then put that back into the stock investments that I sold to make down payment for the new house with some left over.
