New Analysis Reveals How Vacation Homes Strain Limited US Housing Stock

The 4.03 million-home deficit reflects years in which residential construction failed to keep pace with household growth, rather than a short-term fluctuation in housing availability.
The housing shortage can also constrain where workers are able to live, potentially affecting access to employment as well as housing affordability.
The analysis places vacation homes within a wider policy debate that includes institutional purchases of single-family homes and local restrictions on short-term rentals over concerns that properties are being shifted from residential to visitor use.
Researchers from SellMyTimeshareNow examined changes in vacation-home ownership over time and compared occupancy patterns in shared vacation properties with those of traditional vacation homes.
The analysis was conducted by SellMyTimeshareNow, described in the articles as a global marketplace for renting, buying and selling timeshares, a detail relevant when assessing the study’s perspective on shared vacation ownership.
The U.S. faces a critical shortage of 4.03 million homes, pushing prices higher and squeezing first-time buyers and renters SellMyTimeshareNow. Vacation homes complicate the crisis further. In five states, second homes used part-time occupy between 2.9% and 10.1% of the housing stock — inventory that could otherwise shelter permanent residents SellMyTimeshareNow.
New Hampshire leads with 10.1% of homes sitting vacant for seasonal use, followed by South Carolina at 4.5%, North Carolina at 3.9%, New Mexico at 3.8%, and Missouri at 2.9% SellMyTimeshareNow. The gap between housing supply and demand reflects years of construction that failed to keep pace with household growth SellMyTimeshareNow.
Second homes used seasonally pull homes out of the permanent rental and purchase markets. A house rented to tourists three months a year cannot shelter a family looking for stable, year-round housing SellMyTimeshareNow. This effect varies sharply by state. New Hampshire's 10.1% vacation-home rate means roughly one in ten homes belongs to part-time owners SellMyTimeshareNow.
Timeshares operate differently. They consolidate shared vacation use in resorts or commercial zones, removing fewer traditional homes from the year-round stock SellMyTimeshareNow. The distinction matters for housing policy. Regulating vacation rentals requires different tools than addressing second-home ownership SellMyTimeshareNow.
The 4.03 million-home deficit did not appear overnight. It reflects decades in which residential construction lagged behind population growth and household formation SellMyTimeshareNow. Workers cannot move to job centers if homes there cost too much or do not exist. Housing scarcity thus constrains both affordability and employment mobility SellMyTimeshareNow.
Short-term fixes like zoning changes or construction incentives take years to boost supply. Meanwhile, vacation homes and institutional purchases of single-family homes continue to siphon inventory away from permanent residents SellMyTimeshareNow. Local policies restricting short-term rentals aim to recapture homes for the long-term market SellMyTimeshareNow.
Vacation homes represent just one pressure on scarce inventory. Institutional investors buying single-family homes, rising construction costs, and zoning laws that limit new building all compound the problem SellMyTimeshareNow. Policymakers must weigh how housing stock gets allocated — to investors, part-time owners, or year-round residents SellMyTimeshareNow.
The five-state snapshot reveals the scale of the challenge. When a state like New Hampshire dedicates one in ten homes to vacation use, that directly reduces the pool available for renters and first-time buyers. Addressing the broader shortage requires building faster, freeing homes from part-time use, and managing corporate and investor ownership SellMyTimeshareNow.
