MLS records from 2007 to Aug 2026 identify 66 distinct units with bedroom information; each unit is counted once. This is not a verified breakdown of the building's 100 units on Assessor records: units that never appeared in the MLS are not shown, and a unit's layout may have changed since its last record. Not enough evidence yet to estimate the full unit mix.

Unit types are not shown: not enough evidence yet for this building. Exposure is the direction most of a line's MLS listings report. Across Lincoln Park towers, each floor up adds about +0.64% to price per sq ft within the same line (this building alone has too few comparable sales). Line-by-line price premiums are not shown yet: too few sales per line.

Calculators

Run the numbers for a unit here

Monthly cost to own against renting, or yields and cash flow if you rent it out. Start from this building's figures and change anything.

Starting values are this building's medians for the unit type, where enough records exist; property tax is estimated from the building's tax per sq ft, only where enough units without exemptions agree. Change any number. An illustration only: not a loan offer, an appraisal, or tax or investment advice. Confirm figures with your lender, insurer and tax advisor. Nothing you type leaves your browser.
