The CLR (Common Level Ratio) for Allegheny County has been lowered significantly to 63.5% for 2022 and 63.6% for 2023. This means that the property assessment should be approximately 64% of the current market value of the property.

Your tax assessment of 65% seems very fair considering it is a brand new home. I doubt it is worth appealing to get that extra 1 percent off, to be honest.
