Currently I'm looking for some kind of methodology, software or app, that I can use to manage the properties, which will allow for another family member to step in to my role relatively seamlessly if I were to pass in the future.

I will go see samples but figured you folks could give a definitive thumbs down if this is just today's version of cheap linoleum.

Any suggestions on this methodology is greatly appreciated. 

WHAT ARE THE DIFFERENT METHODOLOGIES UTILIZED IN A COST SEGREGATION STUDY?

I’m slowly learning how to identify soil types but like you said….we can’t afford to be wrong right now  jurisdictions are different all over the US.. many still just use perk tests  others do the soil samples so you just have to deal with your current area and regulations.

You will not get a large enough sample size to have reliable information.

After 12 years in the furnished rental game, I'd say that is a pretty good sample size. 

From the REI sample that seemed to be the case, but thus far it seems that that is actually a pretty rare return to get from them (hence my feedback).

The deals I’ve found so far (and to be fair, it’s not a huge sample size yet) seem to make sense and pencil out under this mindset.
