This bill establishes a prohibition against sellers of residential real estate from requiring potential buyers to disclose their down payment amount when submitting an offer. The definition of "down payment" is clarified as the upfront sum paid by the buyer, which is a percentage of the total purchase price, while "residential real estate" is defined as properties serving as dwellings, excluding those with more than four residential units.

Violations of this prohibition will result in a civil penalty of up to $1,000, enforceable through a summary proceeding under the Penalty Enforcement Law of 1999. The bill is set to take effect 90 days after its enactment.
