Maryland indoor moisture briefing Evidence note 44
Mold Concerns Before Buying a Home
Use repair history, inspection limits, specialist findings, and contract advice to understand the property before a deadline passes.
Short answer
Start with evidence you can name
A purchase decision needs property-specific evidence, contract advice, and enough time to understand the water source and repair history. A seller disclosure, home inspection, mold assessment, remediation estimate, and specialist review answer different questions.
Safety boundary: If there is contaminated water, structural damage, an electrical hazard, unsafe access, suspected HVAC contamination, or a health concern, stop and use the appropriate qualified help. For this topic, first note inspection and contingency deadlines in the purchase agreement.
