145 West 129th Street

PLUTO shows a five-story building of 4,630 square feet on a lot 16.7 feet wide and 100 feet deep, zoned R7-2, built in 1899, with six residential units and a recorded condominium (number 3181). Listing records describe full-floor residences with white oak floors and elevator access. A 4,630-square-foot building across six homes works out to about 770 square feet each before common space (our arithmetic), and a listing record puts Residence 1 near 804 square feet. The architect of record is not named in the records reviewed.

Per the offering plan filed with the New York State Attorney General (plan CD220140), the plan was submitted July 7, 2022, accepted December 8, 2022 and declared effective September 6, 2023, with ICER of 145 West 129th Street LLC as sponsor. The record lists six residential units. Our price file shows an initial price of $5,050,000 and a current price of $5,145,000, an increase of $95,000, or 1.9 percent. The Attorney General's detail page did not load in repeated attempts, so amendments were not reviewed. The record shows one unit sold, a figure that predates the closings below.

Recorded sales, per the city's 12-month sales file:

Residence 1 shows no deed in that file. A listing record shows it active at $850,000, or $1,057 per square foot, which implies about 804 square feet (our arithmetic); the record carries no date, so confirm availability. A listing record also reports Residence 6 at $740,000 after a $775,000 list price. Recorded prices rise with the floor, from $590,000 for Residence 2 to $740,000 for Residence 6.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $889/sf (recorded) across 4 sales. Median listing discount 5.9% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01914-7505; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

The plan is effective and the building is nearly sold. Contracts are binding under the plan's terms. Read every amendment.

Use the recorded range. Recorded prices run $590,000 to $740,000. An $850,000 ask for the remaining home sits above every deed.

Closing costs. In sponsor sales the buyer customarily pays the New York State transfer tax (0.4%) and the New York City real property transfer tax (1% at $500,000 or less and 1.425% above). At these prices the state mansion tax of 1% at $1 million does not apply. Use the calculators below to run your price.

Carrying costs and abatement. The plan's budget projects common charges and real estate taxes. No tax abatement was confirmed in this review.

Sponsor control. The sponsor controls the board until enough units close to turn it over. The by-laws set the threshold.
