Most NJ buyers aren't surprised by the mansion tax itself. They're surprised by how it actually works.
Once consideration crosses $1M, the tax applies to the full amount. Not just what's over the line. The whole thing.
What counts as consideration? More than most people expect. Assumed mortgages, seller credits, and financing components all factor in. A deal that reads $975K on paper can clear $1 million once everything gets added up — and that triggers the full tax.
Technically the buyer pays. In practice, it gets negotiated. Market conditions decide who actually takes the hit.
