Build an SMB on top of your real estate (the reverse of #2)Short-term rentals and high owner-participation real estate businesses can have great returns.Obviously not for you if you just want passive RE.We are in the deep end here, where each case should be judged on its own facts and merits by your CPA.You should hire a professional to review your particular situation before you make an investment.

But I agree with @Stuart Udis - when making offers on occupied rental property, I always review the Financials including the RR & T12.

Its essentially in the longterm best interest of the property owner to ensure there is a non-compete clause in all leases; merely for the benefit of securing longterm relationships with the tenants.A diverse tenant mix can attract a wider audience and contribute to a more vibrant environment.

I was also in the military and not a stranger to all kinds of uncomfortable situations, diverse backgrounds of people and how to deal with difficult people in general.

Diversity of visitors.

If the covenant specifically prohibits renting out rooms or STRs, you may be restricted from doing so.You should carefully review the covenants tied to your property to understand the specific restrictions.

What those "trainer" can do is just hire people to write some fake reviews. 

I haven't reviewed the Standard Lease Agreement yet, but all I need is the right to sublet, and possibly some negotiated capital responsibilities (owner pays for repairs over a certain amount or split responsibilities on certain expenses).

A better approach is to network with other experienced passive investors and review the offering together. 

Seems too good to be true, but after reviewing their numbers and deals it's a great investment.
