Vacancy composition
All 1,330 vacant units split into Census's seven categories. Frictional vacancy (units actively on the market) reflects healthy churn. Structural vacancy (seasonal, migrant, other) sits outside the market for year-round residents — high values change how the headline vacancy rate should be read.
Vacant units by type
Frictional vs structural
Seasonal / recreational share of all housing
13.9%
890 units of 6,418 total
⚑ Above the 10% threshold — meaningful pressure on year-round residents from second-home / short-term-rental demand.
"Other vacant" share of all housing
4.0%
255 units of 6,418 total
Census "Other vacant" — units off the market for reasons other than seasonal, migrant, sale, or rental.

Methodology & sources
All figures derive from the 2024 American Community Survey 5-year estimates pulled directly from the Census Data API at the place geography level. State and national comparisons are population-weighted aggregates of county-level estimates (an approximation; ACS publishes its own state and national medians which can differ slightly).
HUD Area Median Income figures are inherited from the parent county (HUD publishes Income Limits at county/MSA level). BLS industry (QCEW) and occupation wage (OEWS) sections from the county profiles are not shown on place pages because those datasets are not published at sub-county geography — see the parent county profile for that context.
The affordability calculator uses a 30% housing-budget rule with a 30-year mortgage. Defaults are 7% interest, 5% down, $2,500/year taxes and insurance, and 0.5% PMI — adjustable above.
