Mold Question

[Joey L.]

Hi everyone,
I have been a member for quite some time on this site but never really posted anything until now. I constantly come here, though, and read posts for learning purposes. Anyway, I'm here because we found mold in our second investment property.  We bought it site unseen; won it on an auction site last May 18th and closed, after waiting for more than a month, yesterday. We hired a locksmith to open it for us and at first everything looks okay, mostly cosmetic, until we went to the kitchen. The bank, I presumed, took out a small piece of drywall there, so my gut automatically told me to look for any signs of mold. None found in the kitchen because the bank removed all of it, probably, but when we went to the garage; access to it is through the kitchen, we found tiny black spots all over the wall. Not so noticeable that my partner even thought they're just part of a dirty wall. Then we went back to the bathroom upstairs, the one on top of the garage, to see if there's also mold there. And, of course, just I suspected, we also found mold. This is our second flip and never really have any experience with mold. And I know, from other people's experience, that mold shouldn't scare us, investors. Am I right? Or, it depends on how widespread the mold is? This is just one of the two questions why I am here today. The second question is if any of you know a good, reputable mold guy/company that serves Dupage/Lane Counties. Property is in Naperville Township City of Aurora. 

Thank you for reading my post and hoping to hear back from you guys soon.
