I'd also add, you need to be sure they can pay and have some savings put away.

Never, Never use your sellers property tax expenses to estimate your future property tax, this is a big mistake done my many people in the industry.If you haven’t sell your Main home where you are living yet you might consider to keep it, because your new home would be triple the amount your are paying right now.

Present it to them as a return on their money deal - “I’ll pay you 8% on your money while I’m borrowing it”  or whatever, and  pay them out of the cash flow on the deal until you can qualify for a refi into your name when you would pay them off.  

For example, I can give you a deed to a property for $1 and NOT pay off the mortgage.

Their "Titanium Service" does NOT mean anything, other than they would ask you to pay $10K to sign up for it.

I'm more worried about keeping my former neighbors happy than I am about getting an extra $100-200/mo.

Why should an investor pay attention to your data or trust your analysis? 

Zillow says it may go for $289k +/-My current tenants are using it for business and pay $2,250 a month.

Section 8 rent payment standards has the city willing to pay up to $3,120 per 3 br unit so I used gross rent of $6,240 given rent for the furnished 2/1 unit would be too variable with partners living there as they please.Phila.gov info:https://property.phila.gov/?
