This is your principal + interest payment, or in other words, what you send to the bank each month. But remember, you will also have to budget for homeowners insurance, real estate taxes, and if you are unable to afford a 20% down payment, Private Mortgage Insurance (PMI). These additional costs could increase your monthly outlay by as much 50%, sometimes more.

 

Mortgage Terminology

In the most basic terms, mortgage "principal" is your outstanding balance. Your mortgage payment consists of interest (see below) and principal. Interest is the cost of the loan, and this goes directly to the bank. The principal portion of the payment goes directly toward your mortgage balance. The principal portion of your mortgage payment increases your equity stake in your home. If your home is worth $100,000, and if your outstanding mortgage balance is $80,000, and your next mortgage payment is $200 principal + $500 interest ($700 total), when the payment is applied, your equity stake will go from $20,000 to $20,200.
Interest is the cost of the mortgage. This is how the bank makes money. Over the duration of a typical 30 year mortgage, interest could potentially cost you 2x the purchase price of your home! Each mortgage payment is principal + interest, with the interest going directly to the bank that services your loan.

Important: Mortgage interest can be deducted from your taxable income. It's a gift from Uncle Sam, encouraging home onwership.
Typical mortgage requirements stipulate that you need a 20% down payment on your new home purchase. If you are unable to afford a 20% down payment, the mortgage industry has come up with a way to help shield their risk, it's called Private Mortgage Insurance (PMI). This insurnace policy protects the bank servicing your mortgage in the event you default. It should be noted that this is an insurance scenario where the person paying the premium (you) is not the beneficiary (the mortgage company). With PMI, you might be able to have a down payment as little as 10%, 5% or less, with the cost of PMI a direct inverse of the amount of your down payment. After all, the less cash you have up front, the more risk for the mortgage company.
