Suffolk County, NY Property Records & Statistics

Suffolk County is one of the most expensive housing markets in the state. The median rent is $2,173, far above the New York median of $928.25 and the national median of $840.25. Renter-occupied housing accounts for 16.27% of occupied homes, below the state figure of 20.16% and the national figure of 21.81%, which shows a county dominated by owner-occupied homes.

The median home value is $566,000, more than three times the state median of $169,000 and the national median of $173,750. The median property tax rate of 1.75% is lower than the state rate of 2.11% but still well above the national rate of 0.74%. Because values are so high, a rate below the state average still translates into substantial annual tax bills for homeowners.

Household incomes are strong, with a median of $121,250 compared with $70,656.50 statewide and $65,108 nationally. That income level helps explain how the county supports its high home values and rents. The unemployment rate of 3.03% is slightly above the state rate of 2.91% and the national rate of 2.87%, so the labor market is close to average rather than notably tight.

Taken together, the figures describe a high-cost, high-income county with expensive homes and rents, moderate tax rates relative to New York, and an unemployment rate that tracks state and national levels.

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

These records are useful when researching a property because they show who holds a mortgage, whether earlier loans have been paid off, and how a loan moved between lenders over time. Buyers, title researchers, and owners can use them to confirm that old liens were cleared before a sale or refinance, and the recorded date ranges show which periods are covered.
