A mold infested building can sell at 300k profit if resolved. Is it worth the risk??

[Alicia Simon]

Hi, 

I am looking at a multi-unit building that has mold in numerous places throughout--on every floor. The home is a short sale and you can not enter because of mold. The home is being sold for 320k, but is worth 900k. There are also fines on property with in the hundreds of thousands, but a quick search said remedying the issues and paying a  manageable fine can resolve that matter. A call to an acquantince that is a licensed mold remover said DO NOT buy the property. However, I saw a full removal could be as much (or as little) as 30k. I planned to rehab the property anyway, as it has alot of damage and water damage too. 

Even if I put 420k into the home total, I'd still be doing well. 

It's been on the market for a few months, so seasoned investors may see the nuances I'm missing.

Do you?

What would you do?

THANKS SO MUCH in advance!
