On a conventional mortgage, when your down payment is less than 20% of the purchase price of the home mortgage lenders usually require you get Private Mortgage Insurance (PMI) to protect them in case you default on your mortgage. Sometimes you may need to pay up to 1-year's worth of PMI premiums at closing which can cost several hundred dollars. The best way to avoid this extra expense is to make a 20% down payment, or ask about other loan program options.
Surprising as it may seem, some folks with hefty incomes find that it’s mighty tough for them to save enough money to make a 20% cash down payment on their dream homes. Using conventional financing, such buyers must purchase Private Mortgage Insurance (PMI) which increases the cost of home ownership and, ironically, makes it even more difficult to qualify for the mortgage. However, if you’re a dues-paying member of the cash-challenged class, don’t despair. Given that your income is sufficiently high, it’s eminently possible to avoid getting stuck with PMI. That is why 80-10-10 financing was invented. It is called 80-10-10 because a savings and loan association, bank, or other institutional lender provides a traditional 80% first mortgage, you get a 10% second mortgage, and make a cash down payment equal to 10% of the home’s purchase price. By using this method, you are no longer obligated to take out PMI on your property.
The same principle applies if you can only afford to make a 5% down, 80-15-5 financing is also available. However, because a smaller cash down payment increases the lender’s risk of default, do not be surprised when you are asked to pay higher loan fees and a higher mortgage interest rate for 80-15-5 than you pay for 80-10-10.
