Yes. 30- and 60-day locks are standard on refinances, and a longer lock earns its keep on government streamlines. An FHA streamline or a VA IRRRL comes with a required seasoning period before you're allowed to close. If the rate is favorable but you haven't cleared that window yet, a longer lock nails the rate down now and protects you against the market worsening while you wait out the clock. No floating and hoping. Two practical notes: - Longer locks usually price slightly worse than shorter ones, because the lender carries rate risk for more days. Match the lock length to a realistic timeline instead of grabbing the longest one by default. - If your window runs short before closing, locks can generally be extended for a fee, though it's cleaner to size the lock right the first time. Nobody can promise which way rates move while you wait, and that's the whole case for locking instead of gambling on the market holding still. If you're timing a streamline around a seasoning date, we can map out the right lock length so you're covered through the waiting period without paying for days you don't need. That's a quick thing to sort out on the free Roadmap conversation.
