We still have people that want their units inspected. Depending on the age of the unit, there may be GFCI outlets missing, interior plumbing that is not done right, or leaking, and perhaps even mold issues that affect individual units. Are the included appliances in good working order? An inspector may also notice roofing or siding on the common building that may require attention in the near future, which may impact condo association resources and assessments.
In our area, these inspections average about $300 - $400, which is money well spent if there are issues.
You may wish to interview inspectors in Milwaukee to see what they might offer you, and how much it will cost. Best wishes!
