A Private Pricing Opinion — what your apartment at 105 Diamond Street would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
105 Diamond Street is a four-residence condominium on a 25-by-100-foot Greenpoint lot. The plan prices the four homes at $7,274,860 in total, an average of about $1.82 million each. That is a little below recent Greenpoint buildings of four homes: recorded sponsor sales at 130 Huron Street ran from $1.89 million to $2.35 million in 2025.
The record here is thin. The plan was accepted in January 2026, but we found no published asking prices, no marketing name, no design credit and no recorded sales as of October 2026. A buyer here will be working from the offering plan itself.
Architecture and residences
The Department of Buildings new-building job, first filed in early 2024, describes "a new 3 story + cellar + basement, 4 family building," 50 feet tall, with about 6,525 square feet of construction floor area. The filing counts the basement as a story, so the record gives four stories while PLUTO shows three floors. Structural and foundation permits issued in August 2024, and the plumbing and mechanical filings were still being amended in 2026. PLUTO dates the building to 2024 and records about 5,940 square feet of residential floor area, or roughly 1,480 square feet per home on average before common space. Published permit reporting says the lot previously held a one-story house.
No layouts, finishes or amenities have been published. Schedule A sets the unit mix.
Offering and pricing
Per the offering plan filed with the New York State Attorney General (plan CD250085), the plan was submitted March 18, 2025 and accepted January 9, 2026, with 105 Diamond Street LLC as sponsor. It covers four residential units and no other units. The total offering price is $7,274,860, the same at filing and now. The Attorney General's plan detail page returned an empty response when we checked in October 2026, so these figures come from a database extract. Amendments were not reviewed. The extract shows no effective date and no units sold.
We found no asking prices in listing records. City tax records still show the property as a single lot, and ACRIS shows no condominium unit lots or sponsor deeds as of October 2026.
Local Law 97
This building is below the 25,000 sq ft threshold at which LL97 limits apply to a building on its own. It is still covered if it shares a tax lot or condominium board with buildings totaling over 50,000 sq ft; confirm on DOB’s covered-buildings list.

What to know if you’re buying
Start with Schedule A. With no public asks, the plan's Schedule A is the only price list. It sets each unit's price, common charge and projected taxes.
Confirm the effective date. Ask sponsor counsel whether the plan has been declared effective and get every amendment. Sponsor closings cannot begin until it is.
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 (1.425% above $500,000), plus the state mansion tax of 1% from $1 million to $2 million and 1.25% from $2 million to $3 million. At the plan's $1.82 million average that is about $33,200 in transfer taxes before any gross-up and $18,200 in mansion tax. Use the calculators below to run your price.
A four-unit condominium. With four owners, each vote, assessment and repair carries more weight than in a larger building.
Certificate of occupancy. Ask where the new-building job stands and whether closings will happen on a temporary certificate of occupancy.
Carrying costs. No tax abatement has been disclosed. Confirm the first-year tax projection in the plan.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
