Fix & Flip with Lots of Mold!

[Matt M.]

Hello,

I'm working with a wholesaler to get a raised ranch to fix & flip.  The lower level is dry but shows indications of mold on the floor, walls, and ceiling throughout.  The lower section of the stairs leading up to the upper level will need to get replaced due to partial rot. However, there is no mold visible on the upper level. On the exterior, there's mold growing up the entire left side almost to the roof and up 3-4 ft in the front of the house. The source of the water is external and can be remedied with a sump pumb/perimeter drainage inside as well as a dry well outside. Lastly, the house has been vacant for 3 years.

Although I'm hesitant to take this on due to the extensive mold, it could be very profitable. So, my question to all you experienced flippers, would you cut and run?  Gut the entire house from top to bottom, inside and out?  Just gut the downstairs where the mold is visible?

Just as important, is there a reason to use a professional mold remediation company versus just doing it myself?  I know this will probably differ by state, but are there legal reasons for using a remediation company versus doing it myself?

I've new with flipping and have always shied away from properties with mold.  So, all input is welcome!

Thanks.

Matt
