What is mortgage insurance?

Mortgage insurance makes it possible for you to buy a home with less than a 20% down payment by protecting the lender against the additional risk associated with low down payment lending. Low down payment mortgages are becoming more and more popular, and by purchasing mortgage insurance, lenders are comfortable with down payments as low as 3 - 5% of the home's value. It also provides you with the ability to buy a more expensive home than might be possible if a 20% down payment were required.
