A full doc loan is one that requires that the borrower present all necessary documents, including income and asset verification to be considered for the home loan. You will need to provide 2 years tax returns with W-2s and current paystubs to verify income and 3 months statements for you asset accounts.
You may be eligible for a Reduced Document loan if your credit scores are high and you have sufficient assets for reserves. Your loan officer can get a quick automated approval that will list the documents required for approval.
