Your basic entitlement is $36,000. For loans in excess of $144,000 to purchase or construct a home, additional entitlement up to an amount equal to 25 percent of the VA county loan limit for a single family home may be available. VA county loan limits, which can change yearly, are available at this link. The loan limits are the amount a qualified veteran with full entitlement may be able to borrow without making a downpayment.
