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 74% above the median residential account in Montgomery County ($623,400, 248,486 accounts).
- The last transfer price is 20% 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.
