Definitely not looking like a great deal. Also what asset class is it? Numbers may pan out, but it's not a desirable area etc etc. Also look at the household income for that area, compare with the rent estimate for your property, to make sure you don't have the most expensive rental on the block or the cheapest either. Also consider the Cash-on-cash, are you making more than 10%, if not, better get in the hard money lending business so to speak :). From what you said you have a very marginal +CF. that means if you have any CapEx or similar you'll jump into negative.
In addition, check pricing trend for the property value. Don't automatically assume all areas are skyrocketing. Consider the reason why the guy wants to sell also. Vacancy 13% is on the higher edge, not alarming but generally you want no more than 8%. Renter density looks nice (I prefer under 25%, again matter of taste and subjectivity).
Since you already used the website :) (thanks for that), the ROI tab shows clearly the breakdown of your ROI sources, you can bank on appreciation ROI on CF ROI etc. Generally you want the deal to CF with 20% down. Don't get tricked into thinking that it's ok to CF with 40% down :). Any deal will CF at a point if you pour enough down, but that's a mistake to think so.
Also, check the schools, that makes an area desirable. Check the type of people and how they get to their jobs. Blue collars most likely want to live near transportation hubs, white collars prefer away, quiet area etc. There are many factors to making the right purchase other than the +CF or a fat Cash ROI.
Bottom line, it appears your deal is struggling on the CF to start with, so my $0.02, move on. I don't think it will be a great deal even if you pay $140k for it. Matter of personal taste, to me, I quickly look at 1% rent to purchase price, if that doesn't pass, I'm not even considering it. Your deal should rent for $1,400/mo at 140k purchase to make it remotely interesting to me.
