I do own two triplexes in Scranton, and I will say the one issue is that you are going to be taking care of the utilities normally if they are not on separate meters, which could take a good amount of money away from your overall cash flow. 

you can utilize a skip tracing company to get contact information for the owners.

I'm trying to figure out a way to utilize a large storage building at one of my MTR listings in Memphis.

What about the utilities, property taxes, maintenance and repairs, capex, etc. are any of those optional for you?

For example, I have a subject property that has 1682 SF on the main floor and 810 SF of finished basement (the majority of which is about 8 feet in height with the exception of some bulkheads to hide the mechanicals) and 271 of semi-finished basement that is a utility room basically (washer/dryer, freezer, hot water heater, furnace, some storage).

Mgt, Landscape/Snow, tax, insurance, utility then debt service. 

If it's the difference between $1800 and $2200 but you have to cover utilities too, not worth it. 

I utilized those funds to purchase 18 rental units.

all materials, all labor costs to others, Not you, utilities, interest payments, permits, licenses, auto/truck expenses, tools needed are all deductable. 

@Mindy PerryReally doesn't matter what software you pick as long as it has the features you want.Two biggest challenges with ALL software:1) None are perfect, so deal with the tradeoffs2) Most users rarely put in enough time to really understand how to utilize the software.
