Unit types

Estimated unit mix — Assessor + historical MLS

470 units on Cook County Assessor records.

Studio 3 · 1%

1 bed 399 · 85%

2 bed 48 · 10%

Unknown 20 · 4%

Estimate: each Assessor unit is matched to its unit line, and the line's bedroom count comes from this building's MLS records (189 units from their own records, 261 from units in the same line). Units without enough evidence stay Unknown. Not a verified floor-plan inventory.

Type	Units (est.)	Median sale price	Median rent	Sales · leases, 24 mo	Near North median rent	Near North price / sq ft
Studio	3	too few	too few	1 · 1	$1,900	$335
1 bed	399	$259,750	$2,275	46 · 92	$2,500	$364
2 bed	48	$432,500	$3,500	10 · 21	$3,800	$392
3+ bed	0	too few	too few	1 · 2	$6,925	$480

Combined residences (two or more units joined) are counted as their original Assessor units in the unit mix; their sales and leases are counted under the combined size.

This building's medians are shown only with at least 8 records of that type in 24 months. The Near North columns are neighborhood medians for the same unit type, for reference — not figures for this building.

Stack plan

Every line, every floor

One cell per unit on Cook County Assessor records, by unit line (columns) and floor (rows). Column heads: the line's typical size and the direction its listings usually face.

Studio

1 bed

2 bed

3+ bed

Mixed or not enough records

Faces east (lake side)

Faces west (city side)

Faces north or south

Mixed / not recorded

Each line shows the unit type most of its units have (an estimate; see “Unit types”), and a line's size and exposure only when at least 3 of its units have records; individual units are not marked. Exposure is the direction most of a line's MLS listings report. In this building each floor up adds about +0.20% to price per sq ft within the same line. Line-by-line price premiums are not shown yet: too few sales per line.

Owning it

What a unit costs to hold, rent against price, and higher floors

Estimates from this building's own sales and leases.

A typical unit, every month

Type	Typical size	HOA dues / mo	Property tax / yr	Dues + tax / mo
1 bed	890 sq ft	$752	$5,240	$1,190
2 bed	1,380 sq ft	$1,218	$8,120	$1,890

Typical size: the type's median price over its price per sq ft (the building's, where the type has too few records), so an estimate. Dues: the type's median in this building's sales. Property tax: this building's tax rate per sq ft for units without exemptions, times the size; owner-occupants with a homeowner exemption usually pay less. Mortgage, insurance and utilities are not included. Try your own numbers in the calculator below.
