Discover how mold impacts real estate transactions. Learn what buyers, sellers, and landlords must know about mold inspections, property value, legal obligations, and insurance coverage.
Mold isn’t just an eyesore or a smell you can ignore—it can kill a real estate deal, lower property value, and expose landlords and homeowners to legal and financial risk. Whether you’re buying, selling, or managing a home or rental property, mold is something you can’t afford to overlook.
In this guide, we break down everything you need to know about mold and real estate: from inspections and insurance to legal responsibilities and practical tips for keeping mold at bay.
What Is Mold and Why Does It Matter in Real Estate?

Mold is a type of fungus that thrives in damp, humid conditions. It spreads through spores and often appears as black, green, or white patches on walls, ceilings, or floors.
In real estate, mold matters because:
- It poses serious health risks, especially for people with allergies or respiratory issues.
- It can cause structural damage to homes.
- It can lead to failed inspections, reduced appraisals, and deal cancellations.
- It raises liability issues for landlords and sellers.
How Mold Affects Property Value

Mold can tank a home’s value—fast.
- Buyers may walk away after a mold discovery.
- Appraisers may reduce the home’s value if mold is present.
- Even after remediation, a mold history can stigmatize the property, lowering buyer confidence.
