Though the city has floated a marginal rate structure and at least two exemptions for the Bring Chicago Home proposal, a coalition of groups pushing for the real estate transfer tax increase are still set on a flat tax.

Bring Chicago Home proposes to raise the real estate transfer tax by 1.9 percent on property sales over $1 million and use the new revenue to fund affordable housing and services for people experiencing housing instability.
