Your entire mortgage interest may not be deductible if you used any portion of the loan on something besides buying, building, or improving your house or if your outstanding mortgage principal exceeds $750,000, or $1 million of your home was purchased before December 15, 2017.
There is also a $10,000 tax limit which applies to all state and local taxes paid in 2021. In addition to the property tax on your home, it would include any state and local taxes withheld on your 2021 W-2s and any state tax you had due in 2020 that you paid during 2021. It would also include sales tax if that is greater than your income tax and personal property taxes on vehicles.
