Fannie Mae Launches its Purchase Application-Level Index (PALI)

Today, Fannie Mae launched its Purchase Application‑Level Index (PALI), which provides timely insight into future home‑purchase mortgage market activity.

The PALI, together with the existing Refinance Application‑Level Index (RALI), is a weekly index derived from applications submitted to Fannie Mae's automated underwriting system, Desktop Underwriter® (DU®). Leveraging DU's broad market footprint, the indices offer a current and historical view of mortgage application activity, helping market participants assess trends in both purchase and refinance demand.

The indices are typically updated on the second business day of each week at 10 a.m. ET.

For more information on the indices, including methodology, FAQs, and publication calendar, please visit our Weekly Mortgage Applications Data webpage.
