I self-manage and because of the aggressive 15 year mortgage I take home just $450/mo which just goes into a savings account, so I don't split out repairs and vacancy. 

If I show the one in person and call the other on the phone is that ok to avoid any legal ramifications in the tenant search process?

A couple things seems funky-1 - Why 6 months to repair if only 50k in renovations?

Before doing the walk through my estimated repairs will include.

If so, then you can't deduct the mortgage interest, but you can deduct a portion of property tax.And you will have some other expenses such as Internet and maybe mobile phone costs - but you will need to separate out "personal use" vs. business use.

Also you may wish to check out local investor groups such as Black Diamond REI in southern Mass and RIREIG in Rhode Island.Since you just bought your first property, I would recommend taking at least 6 months, 12 would be better, learning how to be a landlord of your first rental unit before acquiring another one.Learn about renting a unit out, tenant screening, collecting rent, repairs, capital improvements, handling moveouts, etc.

So your minimum expenses, even with no repairs, capex or vacancy is $1500/month.So best case you are -$211/month cash flow if you don't experience any maintenance, capex or vacancy expenses with the commercial loan.To be fair, you are building WAY more equity with the shorter commercial loan.

It usually takes multiple phone calls.

What's the best/cheapest way to skip trace phone numbers from houses i find from driving for dollars?

I see a few of these every month from wholesalers with a 100k+ spread but like @Brian Pulaski said, ARV is high and repair estimate is low.
