I don’t know for sure regarding the HERO program, but there is a provision in CA residential purchase agreements that a buyer can assume leased items like solar panels.

If you are happy with an annual lease, that should be a pretty safe bet in most places, but if you're talking about short-term rentals, make sure you're somewhere between Kissimmee and Davenport in a neighborhood that permits it.

Their lease is up at the end of July.

Part of the answer to your question will be found in the lease agreement that you signed. 

Hey guysI was approached by a Navigation company about rooftop lease space for an antenna to be used in collecting data for self driving cars, and drones.Its a small unit that receives & transmits data, part of it would be inside my building, and  I would supply the power.all the regular mumbo jumbo in the lease like access with 24 notice, and what not.Kicker is they offered $50 a month, I didn't even  bother to respond, I believe the guy searching for sites is just a hired sales man, he sounded scripted.Anyone in a rooftop lease out there that can share some advice, at $50 a month I wouldn't even consider it.Thanks

Bear with me, I am a newb and just getting into this but … The current tenants are on a lease?

Just go by your lease.  

Also, for NNN, he is likely talking about triple-net leasing. 

The agreement is l get of the lease in 6 months and to be paid 15k. 5k at closing, 5k in 2 months in, 5k at refinance.

I want to learn about wholesalong, lease options, rentals, flips and rehabs.
