My husband and I are soon to be brand new landlords....My father in law recently passed away and we will be taking ownership of the home.

I am not familiar with the laws in your geographic area and will suggest you familiarize yourself on your city's and state's tenant's rights, specifically landlord obligations of habitability.

Laws on some particular subject matters do tend to differ from state to state, but, their refusal to accept your "Affidavits" seems absurd.

Know the law, obey the law, treat people honestly and fairly.That will protect you far more than any LLC or insurance policy or attorney.

I've already read through the Fair Housing laws and the tenant's rights manual that my city gives out. 

These might include Owners with Low Financial Stability Scores and Seniors with Long-time Ownership.As for texting: familiarize yourself with the federal do-not-call laws.

@David Johnson First, I would be sure to check local and state laws regarding leases because they can be different in different areas.

You may want to have a local NC attorney who is familiar with foreclosure laws there to review the collateral to confirm. 

You definitely want to check your local laws governing STRs, both current and any rumblings about future regulations. 

Now I ended up going to what they call a "T14 Law School" and everything turned out fine.
