Sales data through March 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.
