U.S. mortgage debt totals 5.2 trillion dollars. The HMDA database records 1.8 million refinance originations in one recent quarter. Nearly half of mortgage holders would consider refinancing if rates fell.
Key Takeaways
- $5.2 trillion total mortgage debt outstanding in the United States as of Q4 2023, with a large share of legacy fixed-rate loans creating future refinance optionality
- The HMDA database shows 1.8 million refinance originations in Q4 2023 (quarterly count, depending on dataset query).
- Ginnie Mae reported that FHA/VA loans were 33% of the total U.S. MBS market in 2023 (share measure).
- The MBA Refinance Index fell to about 200 (baseline=100) by late 2022 as rates rose sharply, indicating a large contraction in refinance demand
- Refinance share of mortgage applications rose to 66.5% in the week of February 26, 2021 (MBA Weekly Applications Survey), reflecting rate-driven refinancing demand
- Mortgage Bankers Association data show that total mortgage application volume increased to 283.7 from 262.5 one week earlier in June 2023 (seasonally adjusted index level).
- The Federal Reserve’s Survey of Consumer Finances found that 48% of mortgage holders would consider refinancing if rates dropped to certain levels (percent of households with mortgages reporting interest in refinancing).
- J.D. Power reported that 2023 U.S. mortgage refinance conversion rates averaged 3.8% (percentage of refinance leads converted to funded loans).
- The Federal Trade Commission reported that 2023 mortgage settlement/closing cost disclosures showed an average of 8.4 line items per closing statement (number of fee lines).
- Bankrate reported that average mortgage origination charges for refinances in 2024 were about $2,300 (average fee amount).
- Bankrate reported that average “points” cost for mortgage refinances ranged from 0.5% to 1.0% of the loan amount (percentage range).
- Mortgage delinquency rates peaked at 8.2% in Q1 2023 for 30+ days past due in the MBA delinquency survey subset (percentage delinquency).
- The NY Fed’s household debt data show mortgage debt service payments at 6.5% of disposable personal income in Q4 2023 (debt service ratio).
With $5.2 trillion in U.S. mortgage debt, higher rates sharply cut refinance demand, though eligibility remains elevated.
