Just make sure you follow the landlord/ tenant laws in your area to a T, deliver all the notices when and how you’re supposed to etc.

Also, make sure you’re talking to your CPA and attorney about taxes, investment structures (LLC, etc.), and local landlord-tenant laws.

I do not know him, but the path he is leading you is a difficult path    Note difficult does not imply impossible; there are people who are successful with S8 housing    In my area s8 is so undesirable that they write laws trying to make it challenging to not allow S8 tenants.  

So I'm guessing it might depend on your state laws and personal situation. and make sure you know of any sticky items that would eliminate the protection you get from the LLC.

That said I am unsure of the laws in your state. 

As a company policy, not law.

You've probably heard of big Landlords losing property, but only because they were flagrantly violating Fair Housing, running a slum, or otherwise egregiously violating the law.

My brother in law showed it to me when he put in a bunch of blinds in my rental cabin. 

Most cities do not allow "boarding houses" and/or have a "no brothel" law. 

To answer your question yes its enough but in many cases it might be risky.2. location, room to raise rents, occupancy of property, local laws, type of investment are just a few topics that play a huge part.
