Read your Florida landlord tenant regulations and follow the procedure.

A well defined plan will establish who is responsible for what scope, when it will be completed, and what it will cost, as well as a procedure that defines the decision making process when any of the constraints are changed.Developing and enforcing the project management plan is just one of the things a good project manager does, making your construction project successful is what a great project manager accomplishes.

I remember sitting on my porch listening to it & being inspired by some of your procedures.

If it’s self-managed it’s pretty easy to massage numbers.

I was always told that when you own a business (which whether you know it or not you having a rental property is a business) you have to have policies and procedures and structure followed.

The real estate development side of the house is very complex that involves a lot of legal and procedural steps to make it happen.

I'm not licensed in Florida, so no legal advice here... but as others have pointed out, you botched the procedure so it likely doesn't even matter if you are right on the merits.  

In general, yes the 70% rule can be massaged within reason especially in the Bay Area.  

Here contractors have to have a state license, in other states not so but in some cities like Chicago that city has its own licensing procedures and enforcement. 

You have the right to refuse to rent to people who you refuse to make their intentions clear, or refuse to people who change their story.We've had several situations exactly like the one you described where a restaurant owner rented an apartment for employees and we've have a few where massage parlor owners were using our apartments for prostitution and we had serious problems every time.I would not go as far as taking the rental off the market, but you may feel better documenting every conversation, text message and picture.
