Its seems many pros are burying their heads to the regulations or not thoroughly understanding how to interpret STRs in the tax code (the transient rental rules etc).

If you manage homes built before 1978, there's a key regulation to be aware of: the Environmental Protection Agency (EPA) requires property managers and Landlords Nationwide to be certified in lead-based paint handling.

Biggest pati le is getting approved from VA and bringing property up to regulation.

After reviewing the city ordinances, I have a couple of questions about STR regulations.
