Feedback needed on fourplex as buy and hold investment

[Ernad D.]

Dear BiggerPockets community,

I am looking for feedback on a just listed four family property in a less than desirable location (C neighborhood) with some criminal activity.  Building is 60 years old but in decent shape, roof to be replaced in 5 or so years.

Each unit is two bedroom at $550 rent/mo - fully rented, separately metered.  Tenant only responsible for gas/electric.  The property is listed at $110,000 and I would NOT need to do any immediate rehab.  However, it is in a flood zone so insurance would be higher.  Financing would be 25% down payment plus 30 year mortgage at around 4.5%.  At this time, the current owner is not providing expenses, vacancy history, tenant details, repair history, etc.  I am sure once we made them an offer that their answers would be more forthcoming.  

I did find out that this property is being sold due to a dissolving partnership and the price is negotiable, but not a fire sale.  Also, the current owner bought this property for $70,000 in 2013.  

Based on this and below information, I was thinking about making an offer of $80,000.  What are your thoughts, BP?  Is this too low/high?  What else should influence my offer?  I look forward to your responses.
