I would really be relying on my $20k and $10k NJ first time home buyers grant.   

For the rehab process you're going to be heavily relying on frequent and transparent communication with your contractor.

Rely on your agent- that is where their negotiating skills come into play!

They could care less, they are notorious for ignoring problems.He refused to pay the $7 fee the bank charges to cash non-account holders check.So should I worry about it or rely on his lack of sophistication?

I rely on a professional property manager on these tenant-occupied properties she already has been managed.

Probably a really good idea to get a commercial broker that sells multi family to give you their opinion of value, as well as I rely on my one of my commercial lenders to help underwrite deals, always a great resource.

I think the former, and do not rely on an unfinished basement to make a deal work - those are longshots in many cases as a lot of the multi-family were built pre 1955 and finishing basements comes with some risk. 

@Sharon Israel I wouldn't rely on an agent to estimate repair costs unless they have significant rehabbing experience themselves.
