What are the differences between a FHA refinance mortgage loan and a streamline FHA rehab mortgage refi? We are in the process of going thru our first refi on a fixed 30 year FHA mortgage, after 10 years in the home. Our application has been approved, pending a second appraisal, for a standard fixed 30 year FHA mortgage loan. I just read about something called an FHA Streamiline Rehab mortgage loan. What are the differences between the rehab option and a standard FHA mortgage? Our main goal of refinancing is to secure funds for a new furnace and new interior & exterior doors.
