The figures below are illustrative, based on a **3% buyer-broker commission**; your share follows the commission offered on the transaction.

- **Contract Purchase Price**: $850,000
- **Illustrative Buyer Commission Share**: -$12,750*
- **Illustrative Net Cost**: $837,250

*Illustrative Buyer Savings of $12,750 — 50% of a 3% buyer-broker commission, shared at closing.*

## Property Overview

The #427 duplex condo opens into a striking double-height living room with oversized windows that frame soft open greenspace and bring sunlight deep into the space.
The lower level offers spacious living and dining areas with an effortless flow for everyday living and entertaining. A half bath and in-unit laundry add valuable convenience on the main level.

Upstairs, the lofted bedroom overlooks the living room. A second room on the upper level provides exceptional flexibility—ideal as a nursery, home office, or quiet reading retreat. A full bathroom with a bathtub completes the upper floor.

Monthly common charges (including cooking gas, water, and heat) and taxes (PILOT) total $3,297.83, plus a capital reserve assessment of $356.44 per month through April 2032.

Electricity is provided through the building's bulk-purchasing program; the charge on the October statement was $93.
The unit was renovated in 2017.

Sales data through September 2026.

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.
