Apartment with mold??

[Ki Lee]

Hey BP,

I'm considering a MF investment in the Ohio area that has pretty solid bones and good potential.  It's townhouse style garden apartments, 2bd 1ba in a C+/B- area.  Definitely not war zone, but lower working class neighborhood.  I found out that some of the buildings had leaking roofs in the past which caused some molds in ceilings and walls and basements of a lot of the units.  The roofs have been fixed since, but I'm trying to see what this will do for my eligibility to get covered for insurance, to qualify for a loan, and also how much resale value is affected?  Is this a big can of worms for potential liability, too?  Obviously, an inspection is required and there are different degrees, but I want to know if this is generally a big red flag that's going to be a massive headache in the future.  What's your experience?  Do I have to immediately address all mold issues before qualifying for loan/insurance, etc?  The issue is that it spans across many units as the units share walls and ceilings.  fixing the issue for all affected units sounds like a big project. 

Thanks.
