Tracking credits on a home purchase expense

presto

I recently purchased an investment house, intended to be rented.
I just got the purchase statement from my lawyer, including the amount I owe. It includes expenses: down payment, legal fees, maintenance fee for a month, and property transfer tax. Then it gives a credit (discount) for the property tax, for the few months past in 2022 and the previous owner is liable for that tax.
I'm trying to split the transaction which I paid from my bank account. When splitting, I'd like to include the full amount I paid for down-payment, legal fees, maintenance fees and property transfer tax. However, the amount I paid out of my account is less than the sum of those amounts because of the property tax credit.
How can I track the full amounts of each category I've been charged for, separate from the credit I received for the property tax?

Thanks.
