And yet another mold question

[Tyrone Perry]

Good morning BP Family! I'm currently under contract for a duplex that has a slight mold issue under one of the baths & possibly in the attic (hvac drip), which may have dripped to the flooring underneath in a nearby hall. Should I back out? This is so new to me. The duplex is currently occupied on both sides. Property is in Illinois, however I live in Virginia. I'm concerned with current tenants coming after me, once the remediation is completed. Current owners have ignored a ton of maintenance issues, to include the mold. I've asked for $20k off to fix the problems. Is this something concerning? Thank you in advance!
