Use this page to calculate your property tax part of your payment. The rates are per $1,000 of the Sales Price. For example if the Sales Price is $159,000 and the Rate is $13.55—you would multiply 159 x 13.55 to get your annual taxes—divide by 12 to get your monthly taxes. Add that figure and your monthly insurance to your Principle and Interest payment and you got your total payment. In some cases you may need to add Mortgage Insurance. Each year is printable so that you will have a copy for easy reference. You may also want to consider title insurance.
