The median sale price of Evanston homes sold last month fell nearly 20% from the month before to $328,000.

That’s according to data from Redfin, a national real estate brokerage.

The number of properties sold also declined, from 142 in June to 125 in July.

The sales tally includes single family homes and townhomes, condos and co-ops and small multi-family properties with four or fewer units.

The month-to-month change in median sale prices can be affected by the mix of houses that happen to sell that month.

Median sale prices had risen dramatically last year, closing out the year in December at $449,000. But prices have been on a rollercoaster this year with dips and rises on an almost monthly basis.

Median sale prices have been above the same-month-last year level four months this year and down the other three.

Homes have been selling fast for most of this year, with days on market falling to just 11 days in July, 26 days less than in the same month last year.

Inventory — the number of homes listed for sale — has gradually increased, rising from 165 in January to 219 in July. But that’s still lower than the 249 homes that were available for sale in July 2020.
