A Private Pricing Opinion — what your apartment at 845 Second Avenue 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.
845 Second Avenue is a boutique, ground-up condominium completed in 2001 on a single 25-foot lot between East 45th and East 46th Streets — a compact, roughly 100-foot masonry mid-rise carrying 18 residential units over ground-floor commercial space. Its scale is its defining trait: with roughly two apartments per floor, it reads as an intimate building rather than a full-service tower, in a corner of Midtown East that sits within a short walk of Grand Central Terminal and the United Nations.
The condominium was formally organized under an offering plan that took units to market in 2006, with sponsor sell-out closings recorded across late 2006 into 2007. Since then the building has traded steadily as individual-owner condominium stock, with a continuous stream of resales — the strongest single piece of evidence that this is a genuine for-sale condominium rather than a rental building.
Architecture and building operations
The building is a contemporary masonry mid-rise of approximately 100 feet, ten stories tall, built new in 2001 on a 25-by-100-foot lot. Layouts run efficient — predominantly one-bedroom homes in the high-600-square-foot range, some marketed as two-bedrooms — with hardwood floors, dishwashers, and stone-and-porcelain kitchens and baths. Select B-line residences carry private balconies or terraces. Operations: Elevator-served boutique building with a common roof deck and laundry in the building; self-managed in character, without a full-time doorman. Ground-floor commercial space fronts Second Avenue.

How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — the licensed engineer the city requires to sign the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2015–20 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

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.
