@William VreelandKnoxville Pros: With family nearby in Nashville, you may have a solid support system in Tennessee, which could make managing properties easier, especially if you're new to the market.

I started calling other mobile home parks nearby, to get an idea of comparables.

Consider exploring townhomes or single-family homes nearby with fewer HOA restrictions for more flexibility.

Indeed, nearby Cancun airport receives a record number of direct flights from all over the world.

The property was acquired with the long-term vision of capitalizing on the nearby development of a casino, expected to attract workers and residents.

Maybe there's military nearby or hospitals or universities?

Depending on the property location and what amenities/resources are nearby, it could be a good option for an MTR situation as you are contemplating. 

It's much easier to rack up  material hours if you are nearby and able to take on some of the timely hands-on work yourself.I imagine that others have tried to do this while OOS investing but I couldn't speak to their success (or lack thereof)

Some is from nearby development of major mulit family complexes happening in areas like northern liberties, fishtown, point breeze etc.

I think if you understand the price per unit as well as the price per square foot in the zip code and nearby zip codes that will give you a good idea of the comparable market analysis approach and appraiser might use.
