I have a few comments after answering your questions:
Does this mean I can have deduction of 22,369 + 8000 = $32,369 from
mortgage interest and property tax?
Yes you math is correct.
Since $32,369 is greater than the standard deduction amount $25,900
for couple in 2022, going with itemized deduction is superior?
It is that simple. If the itemized deduction exceed the standard deduction then use the itemized deductions.
You are speaking about 2022. I am assuming that you are talking about a future transaction. The lender will be giving you a 1098 showing how much in interest you paid. If you escrow account for property tax through them, they will also tell you how much in property tax payments came out of the escrow account.
Because it is the first year you may find that some of the interest you paid or the property tax you paid is listed on the settlement documents. Make sure you don't double count this, and also make sure you don't forget to count this.
If you paid points for the mortgage that can also be deducted. They may also appear on the 1098.
Once you know you will be itemizing don't forget a couple of other things. You can deduct up to $10,000 in state and local taxes. Property tax is part of that, but so is your state income tax. So if your state taxes income don't forget to include enough of that to hit $10,000.
When you itemize you can also include any charitable deductions you make. Don't forget to include those.
