In this, the final Mortgage Math module, students will learn the best ways to use their mathematical proficiency as a marketing tool. They will understand how to put in perspective the cost difference of renting vs. buying a property, and how buying a property could be easier than a prospective client expected. They will revisit how to calculate the Total Interest Paid, and how to get clients over the initial sticker-shock, and how to present them with different options. This may include changing the amortization period of the mortgage, which can greatly decrease monthly payments at the cost of a higher total price. In the final part of the course, students will review the criteria used to determine the maximum amount of a loan that their client could qualify for.
