Quadruplex deal - run or buy??

[Charli Deeser]

quadruplex 355k. Financing: conventional owner occupied. units rent for $650 $650 $700. (Two tenants Section 8). 3 units have been updated w tile and paint. All 4 have new evaporative cooling. Owner occupied unit can rent for up to $780 at the moment.  Close to grocery, little restaurants, Starbucks. 
Previous appraisal $360k. Neighboring properties are not updated and would not be similarly appraised (I think).

Would this be decent deal to start? What could I be missing in order to make a more informed decision? 
One concern is overpaying in this market and hurting cashflow which may be skimpy first 6-12 months.
