If a home inspection reveals mold problems, it can seriously change the course of the sale. Buyers may request professional mold remediation, repairs to fix leaks or humidity issues, or a price reduction to cover expected cleanup costs. In many cases, they ask the seller to complete all remediation before closing. If mold is widespread, hidden in walls, or linked to long-term water damage, buyers may walk away entirely. Mold creates health and safety concerns, so lenders and insurance companies may also intervene. Addressing the moisture source and hiring a certified mold specialist is essential to move forward successfully.
