The only major difference would be population count and proximity to Philadelphia, in my opinion. 

Here are the major numbers I'm working with.Unpaid Principal Balance: $652,318.91Total payoff amount: $816,335.37Total interest: $98,845.47Total Amount to Reinstate good through 11/12/2015: $271,256.66Daily interest accrual: $46.22Is it safe to say that after I reinstate the loan, the principle balance will be $545,078.71 ($816,335.37-$271,256.66)??

Make sure you have underwritten the replacement cost and remaining useful life of the major systems (roof, windows, hvac, hot water, kitchen appliances, flooring) and that you are funding for these.

So what's the upside in spending extra money on a machine that quite often will cause you major headaches?

I would do a VERY detailed ARV inquiry on this home and a VERY detailed repair cost spreadsheet before going further.  

Any major factors?

I took a beating on a deal involving a busy road and that road was a major factor.How are you advertising it?  

It appears that real estates value there are very reasonable and with no state income tax, I can see why the area is so enticing to major companies like Tesla

My rentals would pay my expenses and I can cash out of the house I have in an HOA now, and put that in index funds as another stream of income that I could tap but will just let grow unless I need it during vacancies, major renovations, etc.

Never had any major issues as a result, just factor it into your calculations/pro-forma to analyze for the added expense appropriately.As for what that expense is, it's all market specific of course.
