Hi Daniel, It depends on a few factors--If the house was renovated and added on to, then it is
assessed already and will be reassessed to included the improvements. If it is totally new construction, then the assesso partially assesses it and then will be fully assess it once completed. On new construction, there is a lag time so sometimes you may have a full year without it being fully assessed. The Town of Mamaroneck is doing a re-assessment of all properties. They will most likely use the sale price as the new assessment. I would check with the Town of
Mamaroneck to see what the taxes would be on a home in that price range.
I hope this helps. Best, Maria Mantis.
