There isn't enough information in here about the current state of the house to be able to advise you, but I would think #3 is a definite no as it seems unnecessary from a cost perspective although that market has scale to accept it.

Also 4th quarter of last year Packwood and county officially did discuss potentially regulating STR's by either limiting numbers or adding a tax to cover increases in local services that are needed.

But this has proved false, and when running comps, this is a big deal. 

There are many ways to skin it but I would go ahead and upgrade to QBO Plus.

Utilizing empty lot space in this way helps to combat the increasing housing prices and limited supply many markets have been experiencing.
