Why Crawl Space Poly + Bath Exhaust Fan + Dehumidifier Condensate Line Triggers "Subject To" Appraisal Conditions
When a residential mortgage appraisal is completed under Interior Moisture Control, any deficiency involving crawl space poly + bath exhaust fan + dehumidifier condensate line shifts the report from "As-Is" to "Subject To" repair or inspection. Unlike general home inspection negotiation items, an appraisal condition tied to crawl space poly + bath exhaust fan + dehumidifier condensate line is a hard underwriting gate that must be resolved and verified—typically via Fannie Mae Form 1004D / Freddie Mac Form 442—before the lender issues Clear to Close (CTC).
