What is your Long Island home worth? You may think your Nassau or Suffolk County home is worth a million dollars or more. Perhaps a buyer or lender won’t agree. The local assessor may believe your Long Island home is worth more than you think it is worth. So, just how is the value of your home determined? First, there is the amount that the Nassau County or the Town Assessor in Suffolk thinks it’s worth – that is what your real property tax calculation is based upon. Then there is an appraiser’s opinion of value based on recent sales in the neighborhood (often called “comps”) and how much a willing buyer will pay in the current market. Are these the same values? Not likely — and if the Nassau County Assessor believes your home is worth more than the actual value, you should be grieving those taxes. https://www.nytaxreview.com/news/what-affects-the-value-of-your-home/
