Most people go for a conventional, 30-year loan from a bank or mortgage company that requires you to make a 20 percent down payment.
You also can consider taking a government-backed loan, which often requires the owner to pay mortgage insurance but might require a lower down payment.
Some counties and cities offer down-payment help or lower interest rates on mortgages for teachers, police officers and other government employees.
The government also offers loans to veterans.
Your best bet: Find out which one works for you instead of signing up for the first one you hear about. Work with a real estate agent and a mortgage banker who know all of your options so you can consider them all before deciding.
