The Average Prime Offer Rate (APOR) is an annual percentage rate that is based on average interest rates, fees, and other terms on mortgages offered to highly qualified borrowers.
Your mortgage will be considered a higher-priced mortgage loan (HPML) if the APR is a certain percentage higher than the APOR, depending on what type of loan you have:
- First-lien mortgages: If your mortgage is a first-lien mortgage, the lender of this mortgage will be the first to be paid if you go into foreclosure. In general, a first-lien mortgage is “higher-priced” if the APR is 1.5 percentage points or more than the APOR.
