Set on an extra-deep block, the home unfolds across approximately 4,000 square feet and is currently configured as an owner's triplex over a private one-bedroom garden apartment. Behind its handsome historic facade lies a residence defined by grand proportions, soaring ceilings, and the timeless character that makes Brooklyn townhouses so beloved. The owner's triplex begins on the gracious parlor level, where tall windows fill the living room with natural light and original details speak to the home's historic charm. A formal dining room creates an elegant setting for entertaining, flowing naturally toward the kitchen and out to a deck overlooking the garden below. It is a floor designed equally for lively gatherings and quiet evenings at home. Upstairs, the second and third floors offer a generous and flexible layout with multiple bedrooms and the potential for home offices, libraries, or creative spaces. The home's impressive 21-foot width allows each room to feel open and comfortable, a rarity even among Brooklyn townhouses. Below, the garden level is configured as a one-bedroom apartment with its own entrance and direct access to the garden, ideal for rental income, guests, or conversion into a spectacular single-family residence. The property will be delivered vacant, presenting a rare opportunity for the next owner to move right in, create a custom townhouse, or design the ideal live-plus-income configuration. Just moments from the cafés and restaurants of Vanderbilt Avenue, the cultural energy of the Barclays Center district, and the green expanses of Prospect Park, the location offers the very best of Brooklyn living. Multiple subway lines nearby provide easy access to Manhattan and beyond. ## Property Details - **Property Type**: Multi Family - **Beds**: 6 - **Total Baths**: 6 - **Rooms**: 8 - **Sqft**: 1,050 sqft - **Stories**: 3 - **Year Built**: 1910 - **Price per Sqft**: $5,952 - **Monthly Taxes**: $827 / mo - **Listed On**: Apr 21, 2026 - **Days on Market**: 143 Days ### Residence Features - Central Air - Washer Hookup - In Unit - See Remarks - Building Garden - Private Outdoor Space Over 60 Sqft - Smoke Free ## Sales Evidence ### Recent closed sales 121 Saint Marks Avenue has 2 recorded sales since September 2021, the most recent for $4,850,000 in July 2022. Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source | | --- | --- | --- | --- | --- | --- | --- | | Entire property (Multi Family) | 5 | — | $4,850,000 | — | July 14, 2022 | MLS | | 1A (Apartment) | 4 | 4,116 | $3,650,000 | $887/ft² | June 13, 2022 | MLS | Every row is a recorded transaction, including ancillary spaces such as storage and staff rooms where they were sold separately. Those are excluded from the benchmark below. ### How this price compares The median closed price for comparable house sales in Prospect Heights is $3,640,000, based on 8 sales between October 2021 and June 2026. This home is asking $6,250,000, $2,610,000 above that median. The middle half of those sales closed between $2,790,000 and $5,149,999. - **Median closed price**: $3,640,000 - **Middle half**: $2,790,000 – $5,149,999 - **Based on**: 8 house sales in Prospect Heights - **Period**: October 2021 – June 2026 - **Median $/ft²**: $1,091/ft² Across the 3 of these sales with a published asking price, the median closed at 95.7% of what it originally asked. 100% of them closed below the original ask. A house is not part of a building of comparable apartments, so this benchmark is drawn from house sales across Prospect Heights. Apartment sales are excluded from it entirely. ### How these sales were negotiated - **Sold vs original ask**: 95.7% of the original ask - **Closed below ask**: 100% of 3 sales - **Listed → in contract**: 38 days (about 5 weeks) - **In contract → closed**: 57 days (about 8 weeks) Across the 3 of these sales with a published asking price, the median closed at 95.7% of what it originally asked. 100% of them closed below the original ask. Half of these homes were in contract within 38 days (about 5 weeks) of coming to market, based on the 7 with a recorded listing date. Once a deal was agreed, closing took a further 57 days (about 8 weeks), based on the 7 with both dates recorded. These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure. Based on 8 house sales in Prospect Heights, October 2021 – June 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.

We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one. Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls. Figures are the New York City Department of Finance assessment roll for tax lot 3011430068. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
