Lending is a highly regulated industry and most things are cut and dry with what they can and cannot do.

If you are investing in a certain area, be aware of the rules, regulations and laws governing real estate in your area.  

Adding on isn't always good, I've seen some crazy things in rural areas where they have less regulations on permits, etc. 

Government regulation from one agency causing consequences against another agency, when each agency originally intended to target the "rich landowner".  

Other than that, consult local zoning regulations.

Which government department rules this type of issue from title company?

Its been my experience that unless there is someone that feels guilty (or the government makes them) it doesn't necessarily pay to do those.

I assume you have studied your state landlord tenant regulations in which case you know the rights of your tenants regarding inherited leases and rent increases.In your situation I would give notice to raise rents on all M2M tenants immediately.

As a side benefit, you would improve your asset protection by taking the excess funds out of the LLC since they wouldn't be available to potential future creditors of the LLC.Regarding the application process, the brokers are subject to "know your customer" regulations so they will need to know identifying information for the human being that is authorized to make decisions on behalf of the entity.  

Do they (Florida government) have price control, property inspection, etc.?
