Count of Second Homes Declines in 2024

Why It Matters

The contraction hints at shifting consumer preferences and could ease pressure on local housing markets, especially in high‑concentration areas.

Key Takeaways

• Second homes fell to 6.2 million, 4.3% of housing stock.
• Florida holds 943,881 second homes, 15.2% of national total.
• Eight states contain half of all U.S. second homes.
• 738 counties have second homes comprising at least 10% of housing.
• Top ten counties hold ~11% of second‑home inventory.

Pulse Analysis

The latest NAHB estimate shows a slight retreat in the U.S. second‑home market, with inventory slipping to 6.2 million units in 2024. After a pandemic‑era boom that pushed demand for vacation and seasonal properties, buyers appear to be recalibrating, perhaps due to tighter credit conditions and higher mortgage rates. While the overall decline is modest, it marks the first contraction in several years and may signal a broader shift in discretionary real‑estate spending.

Geographically, the market remains highly concentrated. Florida alone accounts for nearly a million second homes, or 15.2% of the national total, and eight states together hold half of all such properties. At the county level, 738 jurisdictions report that second homes represent at least one‑tenth of housing stock, and 272 counties exceed a 20% share. These pockets of concentration can distort local housing affordability, inflating prices and limiting options for primary‑residence buyers, especially in popular tourist corridors.

The analysis relies on the Census Bureau’s 2024 American Community Survey and focuses on properties eligible for the home mortgage interest deduction, excluding investment‑only rentals. By narrowing the definition to non‑rental, owner‑occupied second homes, the data highlight consumer‑driven demand rather than speculative activity. As tax policy and interest‑rate environments evolve, the balance between personal vacation use and investment motives will shape future trends, making close monitoring essential for developers, lenders, and policymakers alike.
