@Chris Reid Welcome to the party, sorry I'm late to the game.

I know these 3rd party companies can take a hotel given to them by a buyer, reposition it, and then even manage it for you, creating a semi-absentee owner investment.  

Do you have a good real estate attorney to keep things professional between you?

Sure, you can classify yourself as a real estate professional or setup a property management component and pay yourself a salary that could convert that passive income to earned income, but it generally does not make sound financial sense to do so.The gig work could potentially support a Solo 401k.  

If you have a lease, neither you nor the landlord can terminate the tenancy prior to the expiration date of the lease, unless the other party has violated a provision in the lease.

I wouldn't recommend buying partials on notes that aren't 3rd-party serviced.The contract should spell out exactly how many payments you're buying, for how much and the estimated return you should expect (no guarantees).

It can connect you with many different professionals from around the United States and around the world.

I'm not a financial professional, so seek qualified, competent advice.If the property is in your name, the LLC / business entity structure will not protect you against lawsuits, etc.If that (mortgage deduction) is your criterion, however, you may want to re-examine your priorities.

My philosophy is to be 100% professional and be known for a quality product.
