In September 2024, county councilmember Mike Ertel questioned the county's $2.25 million purchase of an 8.5-acre parcel of land located less than a mile away from Olszewski's house, noting that the county used its own money to purchase the land instead of using state funding through Program Open Space. The Baltimore Banner reported that the land was sold to the county by Norman Anderson and Catherine Staszak, who were both longtime contributors to both Olszewski and his father, though Olszewski said that he didn't know either seller. Olszewski defended the county's purchase of the land—which is set to be developed into a kayak launch and park—saying that he doesn't involve himself in county land transactions and that county department officials used the same process for the acquisition as they did for previous purchases.{{cite news |last1=Miller |first1=Hallie |last2=Kobell |first2=Rona |title=Park purchase near Johnny Olszewski Jr.’s home raises questions |url=https://www.thebaltimorebanner.com/politics-power/local-government/johnny-olszewski-jr-baltimore-county-cuckold-point-PTCMBJ77CZDNTNS74JNRDO624A/ |access-date=September 26, 2024 |work=The Baltimore Banner |date=September 25, 2024 |language=en}}
