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 9% above the median residential account in Howard County ($681,000, 62,119 accounts).
- The last transfer price is 8% 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.
