PMI is just extra fees and has nothing to do with your principal or your interest. Taking on two mortgages is only about the money you borrow and there are no extra costs such as private mortgage insurance. PMI or Private Mortgage Insurance is normally required when you buy a house with less than 20% down.

Private student loans are an excellent option that will help you avoid dipping into savings or using high-interest products like credit cards.

Direct Loans are a better deal for students and cost less for taxpayers. Direct loans are handled directly by the school you are attending. These types of loans typically have lower interest rates than most others.

Student loans are funds provided to a student for educational expenses and are considered self-help financial aid because you must repay the money loaned to you. Loans are the last type of aid for which you are considered, after gift aid and Work-Study. They are available to meet these costs. While students are studying full-time, the loans are interest-free.
