This is perhaps the most popular types of VA Refinance. With VA Streamline Refinance, which is also known as the Interest Rate Reduction Refinance Loan or #IRRRL, the borrower can refinance their existing VA loan with another VA loan, which has a lower interest rate. Not only that you can also increase or decrease the loan period. Qualifying for a VA IRRRL is quite easy, provided you have an existing VA home loan. There is no credit requirement, which mean that even if you have a bad credit you would still be eligible for a VA streamline refinance loan.
