Are we required to make any down payment for getting VA loans?

The VA loan program is designed to help qualified borrowers. So it provides affordable loans without any down payment fees. But you must remember that to get such loan, you must not borrow more than the loan limit of the county you live in.

Down payment isn't mandatory for VA loans. However, if you wish, you can make a down payment on the VA loan

The VA lenders handbook accounts since borrowers don't make a down payment. Plus, they state that VA loans can be for the entire value of the property.
