Where it gets interesting is that the house has 5 mailing addresses associated with it and the fire prevention bureau has on their records it is also a 5- unit house, and I am billed as such upon annual renewals/inspections.

I live in the city and have a freakish map of it in my head that my wife is still shocked by when she gives me an address ("2100 block of _______Ave.?"

That's exactly what I'm trying to wrap my head around.

Anyways, I think @Caleb Brown hit the nail on the head.

I would also add that you join your local REIA chapter (Real Estate Investor Association) as it will allow you to network with other STR owners and get more location-specific information. 

Attend local builder associations or networking events, and focus on small contractors or businesses without in-house permit expertise.Highlight how you save time and ensure compliance—it’s a big value-add.

Finally, short-term rentals can offer potential tax advantages, as many expenses associated with the property may be deductible.

A great way to start is by attending RE events and joining a local investors association.

In addition to that, platforms like HomeAdvisor or Angi are great for finding vetted professionals, and local builders associations or the Greater Beaumont Chamber of Commerce may have directories or recommendations. 

However, I was unsure whether I needed to open a new bank to manage the finances associated with the property.
