Thank you again all. I've learned a lot in the past few hours. At this point I am moving forward with a different lender who reports they "work with you" on these issues. They will give conditional approvals and say unit X: tenant must be removed for unsanitary conditions or the unit must be heavily cleaned.
I spoke to the owner and he said he won't put them on the streets, but he will offer them another unit he owns in a different building.
As far as the deal, it is right on part with every multi fam sale in the area over the last year in terms of price per unit. It is a cap rate of 12, and my home inspector thought the building was maintained well and solid in his eyes. Debt service coverage ratio needed to be 1.25 for the lender and this was 1.67!!
I just got work the appraiser won't finish the appraisal report because the lender pulled out. He is refunding $800 of my $1000 appraisal fee. This baffles me. I paid for it.
Stressful day.
