Unless, of course, the apartments are rented out, in which case the entire property taxes are fully deductible as business expenses, not contributing to your SALT cap.
Plus, you get to depreciate ~3% of the purchase price (technically, one twentyseventh-and-a-half of what you paid for the structure but not the land) each year. And should you bequeath the unit upon your death, the inheritor gets it at a stepped-up cost basis so the government never recovers that accumulated depreciation.
All of this and more is why I love rental properties.
