A Private Pricing Opinion — what your apartment at 427 St. John's Place 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.
427 St. John's Place combines condominium ownership with the scale of a four-story prewar apartment house. Its 16 residences occupy a building completed in 1912 near the eastern end of the St. John's Place block between Underhill and Washington Avenues. The shared outdoor space is a furnished patio with a gas grill, giving the condominium a communal place to sit and eat outside.
The location puts Washington Avenue's shops and restaurants at the end of the block, with the Brooklyn Museum and Brooklyn Botanic Garden to the south. The building's one- and two-bedroom apartments keep the inventory concentrated in relatively compact homes.
Architecture and unit composition
The building occupies a broad, approximately 50-foot-wide lot. Its four-story walk-up form places the upper apartments several flights above the entrance; there is no elevator. Apartment sizes include one-bedroom homes around 650 square feet and two-bedroom homes around 770 square feet, with some larger layouts also present.
The one-bedroom plans can accommodate a dining table or workspace alongside the living area. Windowed kitchens and large living-room windows are features of these layouts. Two-bedroom apartments include exposed brick and living-and-dining areas with substantial natural light. Hardwood floors recur across the apartment types, although alterations over the condominium's resale history have changed individual interiors.
Building operations
The shared laundry room, bicycle storage and patio are common facilities. Private storage also accompanies some apartments. Storage allocation is therefore part of the particular home being purchased; an included storage space should be identified separately from general access to the building's bicycle area.
The largest owner holds five of the 16 residential units, or 31%. That concentration makes one owner's position material to the association's finances, even though it is below a majority of the apartments. Unit count alone doesn't set that owner's share of common charges or voting rights.

Market read. Most recent trades (2025) cleared a median $1,231/sf (floor-adjusted) across 2 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount -1.4% over ask.

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.
