This strategy definitely is showing results however I do believe the greatest indicator of success with an STR will always be its proximity to tourist destinations.

So, you are experienced with physically moving a house and picking it up from its foundation as well as basically being a developer, but not with handling utilities? 

They refuse to leave because either, they can't afford a new place, can't afford to move, don't have the physical stamina to move, or are facing homelessness.Is the eviction length of time normal for your area, or is the owner dragging his/her feet time wise?

Even some markets may be 100% dialed in on AirDNA for projections on 1BRs, 2BRs and 3BRs, but completely glitches out for 4BR for example (if there aren't any other 4BRs in the proximity) - Ironically, if AirDNA doesn't work, it could be an advantage to you if the market is under-saturated with high guest count properties

It's not "hard" in the physical sense, it's just more expensive and therefore pushes your break-even point back further.Lending is a consideration, but not one that should influence your decision of whether or not to invest.

Proximity to Gatlinburg and Dollywood isn't a concern. 

Make it a part of the structure/house by physically connecting them.

The two biggest draws for me was it's proximity to Disney World and it's top notch security.

It details physically deteriorated or obsolete assets as well as the value or cost.A quality study includes a site visit.Interviews conducted with appropriate partiesInterviews with property managers, tax payers, contractors and subcontractors can be very valuable in determining the construction process and specific use of the property.

Proximity to guest population.
