Who owns the homes in Elm Grove?
Ownership reflects the most recent public assessor records (2026).
Of the roughly 2,457 homes in Elm Grove, about 1.8% are held by owners with an out-of-state mailing address (below the Wisconsin average of 5.3%), and about 1.9% are titled to a company or LLC rather than a person (below the state average of 5.6%).
Across Waukesha County, the single largest corporate residential owner on record is Harbor Homes INC, holding roughly 12 single-family homes. Out-of-state and company owners are usually the most willing to sell quickly for cash — they're managing the house as an investment, not living in it.
