A type of refinance for eligible FHA or VA loans, used to refinance into a new government loan.
A streamline loan is a type of refinance for eligible FHA or VA (government) loans; it's a refinance from an existing government loan into a new government loan (ex: FHA to FHA or VA to VA).
This is often called an IRRRL (Interest Rate Reduction Refinance Loan) for VA loans. Streamline refinances have very specific guidelines that must be met and require minimal documentation from borrowers.
