FHA mortgage underwriting isn’t too much more complicated than underwriting for a conventional loan. Both loan types require you to document your employment history using pay stubs or tax returns. And both require a thorough check of your credit history and score. However, the U.S. Department of Housing and Urban Development does set minimum property standards for FHA properties. These standards ensure homes are safe, secure, and physically sound. To purchase your home using an FHA loan, the property will have to pass an FHA appraisal to make sure it meets these standards.
