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.

I ended up asking my father in law and he believe it’s mildew as well.

Since you agreed to give it to him, I would, but when the lease expires, I would ask him to remove that clause or at least have a discussion about why he wants it, if you elect to stay there.I would place in writing the violations on his side, that you know he violated your privacy and is breaking the law to not provide you adequate notice, and that you will take him to court if he does it again.

There is however case law to go by from previous instances.

@Brian Porter @Ryan RichesA bit of an old thread here, but I thought I'd circle back after the Arvada city council passed a new Airbnb law earlier this month that allows short-term rentals in both primary residences and investment properties.

They were told they better settle up before I get home and I laid the law down the best I could.

thats a question best researched with a RE attorney who knows tenant/landlord laws, and probably worth speaking with some local PM's in the area as well about their experience. 

For instance, my mom-in-law fell last June,  hospitalized, and stayed with us till 2 weeks ago.

Any draconian landlord/Tenant laws I should be aware of?

The daughter may have also have an interest in the property by law.
