Super Newbie with a Possible Deal (Need Advice)

[Trip B]

Hi Bp, I've been looking and learning from here for sometime. Putting things I've learned here, I put things in action and put up some bandit signs in the area. The phone started ringing and the first call was this:

Owner says it needs roofing work done and the porch needs to be fixed

There are 2 tenants one is paying $900 a month
the other isn't paying anything but is a family member which a reason he has to sell not making much money.

Owner owes property free and clear and is looking for $70k or best offer.

Comps in the area are about 115k
so 70% is 80,500 - 20k repairs - 10k my fee = 50,500

Supposed to meet with him today, my partner set the meeting up before I could talk to him.

What do you guys think?
