Oak Brook listings fell, but homes still moved faster

Real estate, Oak Brook

The three months ending August 31, 2026 told a clear story in Oak Brook. Fewer homes came to market, and the ones that did sold faster. That combination matters whether you are buying or selling right now.

Realtor.com reported that mortgage rates climbed above 7% for the first time since January 2025. CNBC reported the average 30-year fixed rate hit 7.49% the week of October 7, 2026. Higher borrowing costs usually slow things down. In Oak Brook, they did not.

The Real Estate Data Aggregator counted a median of 51 days on market in ZIP 60523. That is 20 days shorter than the same three months in 2025. Homes are not sitting.

Fewer listings, but prices held

The Real Estate Data Aggregator put the median sale price at $770,000, up 1.7% from the same period in 2025. Nationally, the Federal Housing Finance Agency reported U.S. house prices rose 2.6% from July 2025 to July 2026. Oak Brook's gain was smaller, but prices did not fall.

Realtor.com reported that nationally 20.8% of listings took a price cut in September 2026, the highest share since October 2022. That was not the story the Real Estate Data Aggregator told for Oak Brook's ZIP 60523.

How close to asking price did sellers get?

The Real Estate Data Aggregator put the average sale-to-list ratio at 97.8% for the three months ending August 31, 2026. That was unchanged from a year before. Sellers gave up a little, but not much more than last year.

Nearly 1 in 4 Oak Brook homes sold above asking price. That share rose 5.8 points from a year before, according to the Real Estate Data Aggregator. That is a sign some homes drew real competition.

Speed: more homes went under contract fast

The Real Estate Data Aggregator found that 36.6% of Oak Brook homes went under contract within two weeks of listing. That share was up 2.7 points from a year before. The right home, priced well, did not wait around.

What this means for sellers

The Real Estate Data Aggregator counted only 41 homes for sale, down 22.6% from a year before. Fewer sellers means less competition for the ones who do list. Prices held and the sale-to-list ratio stayed flat.

What this means for buyers

With 42 new listings and 40 homes sold in the same period, supply is tight. The Real Estate Data Aggregator put months of supply at 3.1, barely above a year ago. Buyers are working with a short list. When a home fits, it may not wait.

CNBC reported that refinance applications were 56% lower than the same week one year ago. Buyers financing at today's rates should confirm current numbers with a lender, not rely on older estimates.

These are ZIP-level numbers for 60523. One street inside that ZIP can read very differently from the whole. A home's condition, price point and location within Oak Brook all shape its result. Reach out if you want to talk through what the data means for your specific address.
