Know the laws and be careful what you say, and you’ll be fine!

When our permanent residence was build we made sure part of it was set it up to be finished as a mother in law/ duplex.

In my area I see a lot of "Mother In-Law" apartments and other non-legal 1 bedroom tack ons... often these are garage conversions. 

We bought a home in town that has a mother in law suite with its own entrance and we're renting it out on airbnb.

Unfortunately new tax laws will limit deductions in this scenario.

I’m always firm with lenders who say they do 90% to 100%.

I understand the landlord-tenant laws in parts of California are extremely favorable to tenants.

But remember that tax laws change also.

If not licensed, they are probably violating FL state laws.

Eric, I agree with Jasmine above and get a CPA.Back when I started, both my wife and I had a high income, I had my MBA in finance, but I don't know the in and outs of tax law, which is a subject in itself.
