Look for the Certified Cost Segregation Professional (CCSP) designation, which indicates certification by the American Society of Cost Segregation Professionals (ASCSP).

Of the 3 cities, I am leaning towards Charleston since it is bounded at least partially by water and wetlands which would prevent large-scale urban sprawl and increased supply of housing.

In between we have the life’s, careers, wealth, satisfaction of real people, and their contribution to the enhancement of society. 

@Natasha Rooney How would having a map overview of a market, showing the average Property Class of each suburban city and urban Neighborhood help you with your decision?

For us it varies by property - smaller more urban units can be 80,90% Airbnb whereas larger beach houses can be as low as 30% Airbnb but company wide on 65 or so doors last I checked was 40% Airbnb, 30% VRBO, 30% Other (Direct, Marriott, Google, Booking.com, Jetblue/Allegiant Airlines, others).

Amazon, Urban Outfitters, Walmart, and Barnes and Noble all have warehouses there.  

Urban areas, typically, value design.  

(Please note: if you are changing windows, siding, porch posts, porch structure, and any other major exterior changes ...get ready to paid more money $100.00 and meet the UDC -Urban Design Commission in which they meet twice a month to review your exterior changes for an approval, non-approval or defer which means more waiting before you get to the finish line which is your building permit for your rehab6.

We now have fights over which of the 44,279 genders a person is, kids getting even more bat-sh_t crazy, our society is in melt-down.

The area is not a dense urban area.
