The Alberts are considering buying another house. Their mortgage payments would increase by $500 (to $1500) per month, which includes a $250 increase in interest and a $100 increase in property tax. The Alberts would like to know how much the mortgage payments would increase net of any change in their income tax. Write a letter to the Alberts that contains your advice.

If someone could just help me out with the information, I can get it into letter form.
