We attend an REIA where another member has inquired about renting properties from us - he would sign a lease, pay market rent, etc but he would be using it to run exclusively as an AirBNB.

Maybe she sells to you to pay the Ex and you write a lease to own with her so she gets it back over time?

We signed a 2 year lease through September 2018.  

Lease agreement should cover the majority of Landlord-Tenant issues5.

If the tenants are not on leases because they have been in the units since I bought the building, am I allowed to bring a lease to them that states the new rent is increasing from $558 to $650?

Both units had leases that were broken by these vacancies.  

funding with my own funds, but only paid 20k for the lot (4 unit lot) and plan to pay about 200-300K in building costs.I might just sit on it for 10 yrs as well... if I get 2K appreciation a year thats a 10% return.I also am intrigued on doing what indian tribes do - 50-99 yr long term lease on the land.as I probably could get $2000 a yr for the rest of my life.

Given that last sentence I see one option, screen everyone thoroughly, lease it out and make sure that the lease states they cannot bring others in to live there.

I have been thinking over lease to own and rent to own property.

Hey Gang,I just had a renter who's lease was set to end on June 30th, send me an email on May 20 of their intent not to renew.
