53k Duplex need advice

[Derek Woods]

Alright, I'm currently looking at a duplex for 53k.  Not to rough inside but it does need a new roof  and gutters ASAP and Central heat and air installed.  Windows need updated aswell. 

Privacy fence needs panels replaced and the porch needs painted.

Currently rents for $825 a month total.  With central heat and air $1200-$1250 should be easily done.

The current owner is interested in seller financing the deal or atleast part of it.

I feel as though I'll have close to 70k in at after all repairs and updates.  It should definately be at $1200 then.

Does this sound like an OK deal or a pass??

Thanks.
