You are not required to use it and there are no restrictions as to what type of financing you can use. The program has some good features like no PMI but a bit higher interest rate, no appraisal so no lender required repairs to worry about, 3% down payment but you must pay for some of their closing costs so make sure you ask for some closing costs assistance.
This program is only for Fannie Mae owned homes. As stated below not all lenders are approved vendors for this product.
Have a blessed day!
Each Lender will have specific Loan Officers that have been certified through Homepath to do these types of loans.
I work for PrimeLending and my team is certified by Homepath to do these types of Home Loans. I hope this helps answer your question.
You can go to homepath.com and click on financing to see who lends in your state. Then, you can go over your circumstances with that mortgage person.
