A Private Pricing Opinion — what your apartment at 418 17th 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.
418 17th Street combines an eleven-apartment condominium with the low-rise scale of southern Park Slope. The three-story brick building includes compact one-bedroom homes, larger lower-level configurations and private outdoor space. Selected residences have deeded parking, an important distinction within this small inventory.
The residential lots fall in Tax Class 1A. That classification, used for low-rise condominium units, gives the property a different assessment-growth framework from larger Class 2 condominiums. The building is close to Prospect Park's southwestern side and the 15th Street–Prospect Park subway station.
Architecture and unit composition
The brick exterior is organized around a shallow three-story form. Balconies and terraces accompany some apartments, and wood-burning fireplaces are a recurring feature of the homes. Through-wall air-conditioning and individual washer/dryer hookups are part of the apartment equipment.
One-bedroom layouts make up much of the resale inventory. Larger homes near the base occupy substantially more interior space and may include private garden access. The smaller apartments are generally single-level homes; the lower configurations can involve more than one level. Parking rights are attached to selected residences and should not be treated as a building-wide entitlement.
The site is built close to the residential floor-area allowance of its R5B zoning. Its low-rise footprint and limited lot capacity leave little unused zoning area, even before considering the physical requirements of an enlargement.
Building operations
The condominium is professionally managed. Eleven apartments share the building's brick envelope, roof and common circulation, while each owner's tax lot is assessed separately. The largest owner holds four of the eleven residential lots.
The Class 1A assessment cap limits annual assessed-value growth to 6% and five-year growth to 20%, subject to the rules for physical changes and other adjustments. It is separate from an exemption or abatement, and no property-specific abatement is recorded here.
Fireplaces, balconies and parking introduce responsibilities that do not fall uniformly on every home. For a residence with a fireplace, the flue serving that apartment is part of its operating requirements; for a home with parking, the deeded interest determines what is included in a transfer. Those distinctions should carry through the contract description.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-00875-7501) and verified listing data.

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.
