I would think a detection device would be easy to fool or disable, and difficult to prove in court.I would focus on inspections and look for the following evidence, then document with pictures, written warnings, demands of cleaning/repairs, and follow-up inspections.

It's a tremendous benefit to you to have a customized lease by a legal expert.

Specifically at the spot in question too.Recommendation: 1) Have them send pictures of the mold.

Would you say that turning the current post off and creating a brand new post (with changed pictures + putting some sort of 'pets welcomed' tag) would help?

Owning a rental home with or without house hacking is a pretty basic thing that almost any certified tax professional or accountant should be able to handle.Think a little in a bigger picture about what type of advice you will want: tax, accounting, financial planning?

We would need to see the full picture and discuss the details before being able to provide good advice.

I just want help or advice on building it from the ground up and not getting overwhelmed by all the options at once and take baby steps towards the bigger picture.
