So when you’re talking about those markets, I do think SFH/condos/2-4’s have distinct advantages over MF: better loans (low rate 30 year fixed/no need to refi in 5-7-10 years); much stronger appreciation; usually top notch  tenants who are easier to deal with.)  

If your agent is smart, the most they'll do is make a verbal offer at your price ... then, if the listing agent indicates a deal might be reached, then you formalize into a written offer.2) I'd take a closer look at the rehab costs to try and find ways to shave it down. 

Should it be done with spray in foam insulation?
