Taxes and assessed value for 20 Sherman Avenue
The city's Department of Finance assessed this lot at $1.2M for the 2026 tax year. That works out to $30K per residential unit. Assessed value is what the city taxes, not what the building would sell for, and the two routinely differ by a wide margin. The bill itself turns on the tax class rate and on any exemptions or abatements attached to the lot, neither of which is published here.
20 Sherman Avenue is on HPD's Speculation Watch List
HPD added this building to the list after the sale recorded on February 12, 2020, for $7.8 million. It puts the capitalization rate on this sale at 4.2%, against a median of 5.6% for Manhattan sales in the same quarter. A capitalization rate compares a building's price with the income it brings in, so a rate under the borough median means the buyer paid more than today's rents would usually justify. The city keeps the list under Local Law 7 of 2018, and only rent-regulated buildings can be on it. The listing is about the price. It is not a finding that the buyer did anything wrong.

Rent stabilization at 20 Sherman Avenue
DHCR registration records list 40 rent-stabilized units at this building in 2023, the most recent year PulseCities holds. That is up from 39 units in 2018. Registration is building-level and does not settle the status of any single apartment; the rent history does. Checking your own apartment starts with the free rent history from the state. That is the only binding answer, and it takes time to come back. While you wait, you can get an email when the record here moves: a deed, an eviction, a permit or a violation filed on this building.

What is 20 Sherman Avenue assessed at for property taxes?

What is the displacement risk around 20 Sherman Avenue?
10040 (Inwood) scores 40.4 out of 100 on the PulseCities displacement index. The score reads five ZIP-level signals: LLC acquisition rate, permit intensity, 311 complaint volume, executed evictions, and serious HPD violations. It describes the area around the building, not the building itself.
