The viewer Milwaukee County publishes
Begin with the Milwaukee County parcel viewer; it includes every assessed parcel around Brown Deer and Hales Corners.

With a lot near Brown Deer, the record panel typically gives the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
A word on accuracy
Listed acreage is an assessed number; only a licensed surveyor establishes the real boundary for a parcel near Brown Deer. With a lot near West Allis, records update in batches, so a deed recorded last month might lag behind.
Keeping a record
Save a screenshot of the lot near Shorewood and its record panel, so you have it when calling an office.
