Most loan programs require some amount of down payment as initial equity in your home. Minimum down payments requirements range from 3% - 25%, depending on the loan program and purpose of the loan (primary residence, investment property, etc).
However, there are a few loan programs that may allow for a 0% down payment to qualified borrowers:
VA Loans: Some Veterans may qualify for a loan program with a 0% down payment.
USDA Loans: Some borrowers may qualify for a USDA loan with a 0% down payment for a home within designated rural areas.
Talk you your Loan Officer to see which options are available to you.
