The VA IRRRL 36-Month Rule: How to Know If Your Rate Do-Over Pays Off
Joseph locked his VA loan a couple years back. It felt like a good rate at the time. Then rates started sliding, and Joseph found himself doing the thing a lot of veterans do: pulling up rate news and wondering if he left money on the table.
He's not wrong to wonder. But the question isn't just whether rates dropped. It's whether the numbers actually clear a specific test VA built into the process.
What an IRRRL Actually Is
If you already have a VA loan, your refinance path is usually a VA Interest Rate Reduction Refinance Loan, an IRRRL. It's sometimes called a VA streamline refinance because it skips steps a normal refinance requires. In most cases there's no new appraisal and no re-verification of income. It exists specifically for veterans in Joseph's position, who already have a VA loan and just want a better rate on the same property.
The 36-Month Recoup Test
Here's the part that gets skipped in a lot of conversations. VA doesn't just let any rate improvement qualify. There's a recoupment requirement: the closing costs on the new loan have to be paid back through the lower monthly payment within 36 months. This is spelled out in VA's underwriting guidance for IRRRLs, referenced in VA Pamphlet 26-7. If the math doesn't clear that window, the loan isn't supposed to move forward as an IRRRL.
This protects veterans from refinancing into a deal that costs more than it saves over a reasonable stretch of time. It also means the rate drop by itself isn't the whole story. The costs matter just as much.
How to Run the Math Yourself
Joseph's check took about two minutes, and yours can too. You need four numbers: your current rate, your loan balance, the closing costs quoted on the new loan, and your new estimated monthly payment. Subtract the new payment from your current payment to get your monthly savings. Then divide the total closing costs by that monthly savings figure. The result is your recoup time in months.
If that number is under 36, the refinance is doing what it's supposed to do, it pays for itself well within the window VA expects. If it's over 36, it may still make sense down the road, but right now the costs are outweighing the benefit on the timeline VA looks at.
Why the Lender You Call Matters
Here's something that trips up a lot of veterans: the recoup math changes depending on which lender is quoting the costs. Two lenders can offer the same rate and land in very different places on the 36-month test, because their fees are different. A situation that comes up often is a veteran getting a quote that doesn't clear the window from one lender, assuming that means it's not worth doing, when a different set of costs from another lender would have cleared it easily.
That's why I work with more than one VA lender instead of a single rate sheet. If one lender's numbers don't get a veteran under 36 months, I check others before telling them to wait.
If you have a VA loan and you've watched rates drop since you locked, run Joseph's check on your own numbers. Rate, balance, costs, monthly savings, divide it out. If it clears 36 months, it's worth a real conversation. If you want help running it, call 843-LOW-RATE.
