Property Inspection Waivers: Disaster Reminder Exclamation Point

Loans in process that will be secured by properties located in a disaster-impacted area are ineligible for property inspection waivers (PIWs). We periodically update our systems to deactivate PIW offers in certain disaster-impacted areas that can identified by county or ZIP Code boundaries, but we are unable to identify and de-activate PIW offers on all properties that may have been impacted by a disaster. For more information, view the PIW FAQs and the Assistance in Disasters page.
