If FHA denies the application, FHA will provide written notice to the applicant that includes an explanation of the reasons for the denial. The applicant may submit an appeal of the denial decision through the online application within 30 days of the date of the denial.
All reasons for disapproval must be addressed before resubmitting the application. Applicants are limited to two appeals and each resubmission counts as an appeal. If the denial is sustained, the applicant may submit a second appeal through the online application within 30 days of the date the denial is sustained. If the denial is sustained a second time, the applicant will be ineligible to apply for FHA approval for a period of 12 months.
The FHA Online Application is available on the How to Become an FHA-Approved Lender web page at https://www.hud.gov/program_offices/housing/sfh/lender/lendappr
