Homeowner's Insurance
Homeowner's insurance will always be required and must cover the replacement cost of the property.  It should include coverage for damage due to fire, wind or other disasters.

Flood or Quake Insurance
Flood insurance may be required if your home is located in one of the designated flood zones established by the Federal Emergency Management Agency (FEMA).

Private Mortgage Insurance (PMI)
PMI is required when the downpayment on the home is less than 20% of the home's value.  See more information on PMI at What is PMI?

Title Insurance
You can obtain a lender's title policy, owner's title policy or both.  The Lender will require that you obtain a lender's  policy.  Title policies are used to protect the policyholder's claim to title in the property.  (i.e. they want to make sure that the person selling the property has the legal right to do so).
