@Ian Ippolito you said that you evaluate almost a hundred deals a month.

@Jesus Quintanilla I have a couple HELOCs and every lender I spoke with back when I was getting them evaluated my DTI ratio.

I would re evaluate the costs of your current vendors and then maybe contact some other local property managers in the area to see how they compare.

@Jake Somers Welcome to BP and the wonderful world on real estate.Before we dive into evaluating this property it would be good to understand your objective.

In the first one you should encourage her to evaluate the deal on its own merits and circumstances and offer terms she would be comfortable with.

Recommend using an tenant evaluation app by TransUnion there the tenant actually pays for the application and the company does the full background check.

In other words, you are evaluating the property as to what repairs and or improvements you want or need to make.  

@Mark NavarreteA good read on evaluating a market, or searching for the optimum market, is Emerging Real Estate Markets by David Lindahl.

I use 8% for evaluation purposes or 1 turnover per year, For those landlords that used 2% and aren't collecting rents for 6 months they have to collect rent for 300 months before turnover. 6/300=.02 or 2%. 

You are evaluating what income it will produce if it was a straight investment.
