Questions
Arrears or in advance?+
In arrears means this year's taxes are billed next year, so the seller credits the buyer for the days they owned. In advance means the seller already paid ahead, so the buyer reimburses them. Illinois, Ohio and much of the Midwest pay in arrears.
Why would the proration be more than 100%?+
Where the next bill is expected to be higher than the last one, contracts often prorate at 105% to 110% of the last bill. Cook County contracts commonly do. Use what the contract says.
Who owns the day of closing?+
Usually the buyer, so the seller's share stops the day before. Some contracts and states give it to the seller. Flip the toggle under More details.
What about HOA dues, rent and interest?+
Those are in the Closing Prorations calculator at techybroker.com/calculators/closing-prorations, which does the whole settlement statement.
