If you are going to make a loan and wondering what your monthly payments will be, you can use this
mortgage calculator to figure out payments,
based on the real estate sale price, the term of the loan desired, the buyer's down payment and the loan's interest rate.
This calculator factors in PMI (Private Mortgage Insurance) for loans where less than 20% is put as a down payment. The Mortage Calculator also takes
into consideration "average" county property taxes, and the effect on the total monthly mortgage payment.
