Components of a Mortgage
 
A monthly mortgage payment can contain several components:
Principal
The original balance of money loaned.
Interest
The charge for the use (loan) of money.
Property Taxes
The county assessor charges property taxes based on the value of your home.
Insurance
Protection against loss resulting from certain hazards, such as theft or fire.
Private Mortgage Insurance (PMI)
Loans with smaller down payments involve greater risk for the lender, who requires protection in case the loan goes into foreclosure. Anything less than 20 percent down payment usually requires PMI.
