what is the maximum loan size the VA will do on a streamline modification

A streamline is not a modification. A streamline is only for the amount you currently owe. It is used to reduce your interest rate. A loan modification is when you are unable to afford your mortgage payments and are asking for a 2nd chance on the mortgage. This usually means you will receive a reduced interest rate for a short period of time. If you are looking to take cash out, this is called a cash out refinance. The maximum amount you can borrow is based on your ability to repay the loan and the properties appraised value. As of Jan 1, 202, there is no longer a VA loan county limit. source https:www.vahomeloancenters.org
