What this means
- Maryland reassesses each property every three years; increases are phased in over the following three years, and the Homestead Tax Credit caps the yearly increase on a principal residence.
- Assessed 332% above the median agricultural account in Washington County ($261,900, 3,345 accounts).
- The last transfer price is 28% above the current assessment.
- Built before 1978: Maryland requires rental units built before 1978 to be registered with MDE and to pass a lead-risk reduction inspection.
