Thanks for the feedback. here are some more details:
20% down payment; 20 year mortgage
Gross rents $2150/mo
taxes $1,270/yr (yes that is correct, I quadruple checked)
insurance approximately $3500/yr
utilities covered by tenants except water = $250/mo
Cash flow $158/mo
After all rents are raised (and units are rehabbed) Gross monthly income estimated: $3,800/mo
Cash Flow: $900 (includes extra 10% for property management)
C class neighborhood
currently no tenants have leases (yikes)
I have no cash reserves for updating (my partner has some but he's not sure how much he wants to put in). The thought was since the place cashflows as is, then every penny we could save we would slowly turn around each apartment one at a time. We most likely will have to ask 1 tenant to leave since part of his apartment has a roof leak that has not been fixed and I just don't think anyone should be living in it like that (very strong musty odor). That will be the first apartment to get fixed up.
Owner is not negotiating on price... $130k is lowest he will go.
I believe the owner has some records to show me (like P&L), but not sure if he has exact records of rent or not. That would be a deal killer for me as I'm not going to take his word for it (I'm sure he's a great guy).
Appreciate all the feedback. Biting off more than I can chew? No cash reserves may be the biggest red flag (and that's on my side of the transaction).
