Property Tax Relief For Small Multifamily Property Owners

With unemployment at the highest it has been since the Great Depression, many American families are struggling to pay rent. Last month, a third of all renters failed to pay on time – a number that will likely increase as unemployment continues to rise.

In the Chicago area, evictions and foreclosures are banned during the shelter-in-place order. During this time, mom-and-pop building owners with 10 or fewer units are likely to be hardest hit, along with other small, multifamily properties and low-to-moderate income housing.

For Cook County’s small multifamily building landlords, it is a threat that makes the property tax assessment process even more important. Nearly half of Chicago residents are renters, according to the U.S. Census Bureau. Smaller building landlords face the prospect of a growing number of tenants struggling to pay their rent. For landlords who cater to Chicago area college students, the prospects may be even grimmer if the pandemic interrupts a return to campus in the fall.
