The borrower is not allowed to receive any cash back at the closing nor pay off any consumer debt such as credit cards or installment loans on a VA refinance loan.  Otherwise it would need to be a VA Cash Out Refinance.

On October 16, 2008 VA made changes to it guidelines that now allow a cash out VA refinance to go to a new LTV of 100%.  Please see the Cash Out Section.  Additionally, Congress raised VA’s maximum loan amount for these types of VA refinancing loans. Previously, these VA refinancing loans were capped at $144,000. With the new legislation, such loans may be made up to $729,750 depending on where the property is located.

This type of VA refinance home loan is generally referred to as a "Rate and Term" refinance.
