WHAT THIS PAGE WILL NOT TELL YOU
It will not give you a refi-candidate count. FHFA publishes five rate bins and nothing finer, and today's 6.58% falls inside the 6% and above bin — which also holds every borrower between 6.00% and 6.58% who is still below market. Splitting that bin would require a within-bin rate distribution nobody publishes, so the honest object is an interval: at least 84.6% of the book is locked below market, and at most 15.4% could be in the money. A midpoint of those two would be a number, not a measurement.
NMDB is a ~5% nationally representative sample of closed-end first-lien 1-4 family mortgages, not a census. VALUE1 is count-weighted (each sampled mortgage represents 20 actual mortgages); VALUE2 is the same statistic weighted by mortgage amount. Cells FHFA suppressed for disclosure control arrive suppressed=true with NULL values.
