Mason County, WA Property Records & Statistics
Mason County has a median rent of $1,268.50, well above the Washington figure of $1,019 and the national median of $840.25. Only 16.27% of occupied homes are renter-occupied, compared with 25.55% statewide and 21.81% nationally, so the county is dominated by owner-occupied housing and has a smaller rental market than most.
The median home value is $351,000, higher than the state median of $318,300 and roughly double the national median of $173,750. The median property tax rate of 0.69% is lower than both the state rate of 0.77% and the national rate of 0.74%, which softens the cost of owning a relatively expensive home.
The median household income in Mason County is $69,489, slightly above the state's $68,789 and the national $65,108. That income level supports the higher housing costs better than in many counties, though the combination of high rents and values still points to a market that is costly for newcomers. The unemployment rate of 2.91% is just under the state's 3.02% and a bit above the national 2.87%.
Overall, the figures describe a county with above-average housing costs, low property taxes relative to the state, a high share of homeowners, and incomes and employment in line with or slightly better than Washington as a whole.

Assignment and release records track a mortgage after it is recorded. An assignment shows that a mortgage was transferred from one lender or loan holder to another, while a release shows that the loan was satisfied and the lien removed from the property.

The date ranges also make it easier to focus on a specific period in a property's history.
