Common Questions

Do I have to disclose mold to buyers?
Disclosure requirements vary by state, but in general, known material defects that affect property value or habitability must be disclosed. Mold typically falls into this category. Check your state's specific requirements, but when in doubt, disclose. Non-disclosure can lead to litigation after closing.
What if my seller refuses to disclose known mold?
This puts you in a difficult position. You cannot make disclosures on your client's behalf, but you also cannot participate in concealment. Document your advice to disclose in writing, and consider whether you can ethically continue the representation. Consult your broker and potentially an attorney.
Should I recommend mold testing during inspections?
It depends on the situation. Visible mold, musty odors, or a history of water damage warrant testing. However, routine mold testing isn't always necessary. Guide clients to make informed decisions without creating unnecessary fear.
How much does mold remediation typically cost?
Costs vary widely based on the extent of contamination. Small areas may cost $500-$1,500, while larger projects can run $3,000-$10,000 or more. Use our cost estimator to get ballpark figures for client discussions.
What should I tell buyers who are concerned about mold?
Help them understand that mold is common and usually fixable. The key is addressing the moisture source. Professional testing can provide clarity, and remediation costs are typically quantifiable.
