API, files, or your warehouse. Daily, weekly, or hourly.

How fast do mortgage finance feeds refresh, and which formats arrive?

Format coverage leans warehouse-friendly: CSV appears in 8 of the 10 records against 42.1% catalog-wide (734 of 1,744), JSON in 4 of 10 against 38.7% (675), XLSX and ZIP in 4 each, and XML in 3. SAS and ASCII arrive only with the AHS microdata, and only the HPI ships a SQL variant.

What should you avoid building a product on?

Second, truncated history. The Fed's legacy Mortgage Debt Outstanding table froze in March 2020 when Z.1 restructured, and Ginnie Mae retains disclosure history only to January 2020, so point long-run backtests at sources whose archives run deeper rather than assuming continuous coverage.

Third, undocumented access. Other industries for this persona live on our all developers-builders resources page.

Straight answers

How do you integrate commercial & residential mortgage finance data into an app?

Load AHS microdata annually into a warehouse, parse NMDB ZIPs quarterly, and pin snapshots - some histories stop early, with Ginnie Mae retained to January 2020.
