One way to avoid the tax is to rent out the residence: https://comptroller.nyc.gov/reports/the-pied-a-terre-tax-and...

It's interesting that people choose to leave their properties vacant - They're effectively "taxing" themselves by foregoing rent (4+%/yr cap rate).

Is vacant real estate even a good investment?

No, which is why there are very few vacant units in NYC: 1.4%-ish percent of total supply, whereas the rule of thumb I've heard is that around 5% is the sign of a reasonable equilibrium.

(In a well-functioning real estate market there are some units offline due to vacancy, turnover, and renovation, so we don't expect 0%. High vacancies of e.g. 10% suggest insufficient demand for the supply.)
