Simply put, assessments are an individual owner’s share of the common monthly expenses in a condo building. These typically include the cost of personnel (doorman, maintenance staff, management staff, etc), general building maintenance, building insurance, water and garbage pick-up, but also can include things such as heat, electric and cable depending on the building. Assessments can vary widely depending on the age of the building, number of units and the amenities that are included. Since these are a recurring expense in addition to your mortgage, it is always important to factor this number into your monthly housing expenses when your are purchasing your next home.
