Need help identifying an opportunity

[Aaron Vela]

Hi, I'm new here and am very interested in buying and holding properties to setup passive monthly income from the rent.  I don't have much money to start with and don't want to get into something that will end up costing me money instead of making me money.  So here's the deal:

There is a property I'm looking at that is in an older well established neighborhood.  I'd guess between a Class C and B.  It is walking distance to a public library and close to grocery store. I have not seen it first hand, only through pictures.  It looks recently remodeled both inside and out.  It is an older home built I think in the 40s.  It has old character.  It was sold in 2012 for about 65000 and is up for sale now at 90000.  My concerns with older homes is of course the plumbing and electrical; I don't want to have to update that kind of thing.  Neither would I like to put money into the central AC system.  Those are my main two concerns.  

Having said that, it is an 1100 Sq Ft 2bd 1br home and a good guess is that it would rent out for about 750/month.  If I attempted to purchase it I would make an initial offer of 71000 and willing to go up to 80000.  Does it sound like a good deal?  I have never done this before.
