This is a very subjective topic. Studies have shown that mold can have a very negative impact on the house value. Full disclosure laws requires that mold issues in the house must be revealed to all prospective buyers whether they were in the past or not. Now buyers will see the report, but in the end it is so much easier to sell a house that had $100 in mold remediation, then a house that had $10,000 in repairs so it is imperative to fix the problem right away.
Studies have been done where home prices dropped as much as 40%. This is a very serious case, but in the end this is why you need to fix the problem early on before it becomes this large. Mold is one of those issues that most homeowners don’t want to deal with and ending sale price will verify this.
People are very reluctant to dive into a house that had issues that they themselves are uneducated on. We all know what mold is, but not everyone is willing to take a risk on the unknown. Mold could have been removed recently and still be very prevalent in the house, but be in areas not visible to the human eye, like behind drywall.
This is why it is recommended that you have a professional come out who can test spore counts in all areas of your home to make sure the full problem is handled in one shot. Cutting corners when it comes to mold is going to cost you, one way or another.
