A Private Pricing Opinion — what your apartment at 103 Joralemon 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.
103 Joralemon Street is a 25-foot-wide, 1899 building on a 90-foot-deep lot in the Brooklyn Heights Historic District, the city's first designated historic district. PLUTO records about 6,000 square feet of residential space. The sponsor bought it for $6,050,000 in a deed dated January 7, 2026, per ACRIS, and is converting its five apartments into four condominiums.
The offering plan prices the four homes at a combined $12,980,000, or an average of $3,245,000 each. That is about $2,160 per square foot across PLUTO's 6,000 square feet, before deducting common areas, and about 2.1 times the purchase price. The gap is the sponsor's renovation budget, carrying and sales costs, and margin.
A four-unit condominium lets a buyer own part of a historic-district house without a co-op board, at a price well below a whole Brooklyn Heights townhouse.
Architecture and residences
Mortar Architecture PLLC filed the main alteration in January 2026. It describes an interior renovation and façade alteration of the four-story-plus-cellar building, converting five dwellings to four, with an estimated cost of $838,000 across about 7,900 square feet of construction floor area. The permit issued July 6, 2026. Related filings cover new heating and cooling, plumbing fixtures and sprinkler heads, all permitted between June and August 2026. Interior demolition was signed off in October 2026.
The Department of Buildings completed the condominium subdivision of the lot into four tax lots on September 9, 2026.
The building was last altered in 2010 and 2011, when a ground-floor doctor's office became a fifth apartment, per Department of Buildings records. Layouts, sizes and finishes for the four new homes have not been published; read Schedule A of the plan.

What to know if you’re buying
The plan is accepted but not effective. The sponsor can sign contracts and take deposits into escrow. The plan becomes binding only when the sponsor declares it effective.
Buying before completion. Renovation permits issued in mid-2026. Ask for the construction schedule, the target date for a temporary certificate of occupancy, and what happens to your deposit if delivery slips.
Historic district. Exterior work requires Landmarks Preservation Commission approval. Ask whether the façade work and any rooftop changes are approved, and what restrictions bind future owners.
A four-owner condominium. Four owners share every building decision. Read the by-laws on repairs, insurance, the roof and any garden, and confirm which outdoor areas are limited common elements.
Tax class. Small condominiums may be assessed differently from larger buildings. Ask which tax class the plan's projection assumes.
Closing costs. In sponsor sales the buyer customarily pays the New York State transfer tax (0.4%, or 0.65% at $3 million or more) and the New York City real property transfer tax (1.425% above $500,000), plus the mansion tax: 1.25% between $2 million and $3 million, and 1.5% between $3 million and $5 million.

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.
