Just seeking advice on the best way to approach such an idea.

The driving factor is that there are 20-30 percent more rentals on the market than there were a couple of years ago - particularly in the outlying areas - while visitors to the GSMNP has only slightly increased in 2023 over 2022.  

Once you have this team in place, you should be able to invest in any market confidently.As for picking a specific market - I would go after one with an increasing job and population growth.

No STR won't ever be a thing of the past, does no one pay attention to the increase in bookings and even users on the OTA's.

This assumes that the improvement increases the value of the property, and the points are directly related to those improvements.

It might not directly increase the rent, but having a solid sewer line could attract tenants and save you some trouble down the road.I recently had to replace one of the pipes in my home, and I found a comparison site that came in real handy.

If the property is located within the official boundaries of an urban renewal or urban redevelopment district, then you are entitled to be paid for anything at all you do that increases the value of the property.

It is more so an annoyance than anything as this money would just be set aside for future purchases but I already am considering the suggestion of @Wayne Smith by increasing late fees and also filing notices earlier in the process. 

Would love for my CPA to give me replies, yet am seeking people who are well versed, than ones am encountering.

I virtually never get a 2nd complaint but if I do they ar3 not a preferred tenant and their rent increase reflects this.
