A builder is offering you a 5% mortgage rate in a market where everyone else is quoting 6.5. So what's the catch? Here's the setup, and it's a real one. You're buying your first place in the Phoenix Metro. You'll live in it a year, then rent it out. So you're buying it as an owner-occupant, which matters here. It's why the builder's best rate is even on the table. And you've got two houses on your spreadsheet. The first is a brand new build, $415,000, $415,000. Never lived in, nothing to fix, and the builder is dangling that incentive. They'll permanently buy your rate down to 5%. The second is a resale, two streets over. A solid 2019 house, good bones, nothing deferred, $385,000, $30,000 cheaper. At the going, six and a half. Same street, same 20% down. One's $30,000 cheaper on the sticker, your gut says, buy the cheaper house, obviously. Then you run the payments. And your gut is wrong. The new build, the expensive one, you're financing $332 at 5%. That's $17.82 a month, principal and interest. The resale, the cheap one, smaller loan, $308, but at six and a half, nineteen forty-seven a month. Read that again. The house that costs $30,000 more carries $165 a month less. That's backwards. Call it $2,000 a year every year on the price of your house. And when you rent this place out, that monthly payment is the single biggest lever on your cash flow. Two grand a year is the difference between a deal that breathes and a deal that's tight. So the more expensive house is the cheaper house. Now what? Three options. And I want you to actually pick one. Option A, take the buy down. $165 a month cheaper, a permanent 5%, a brand new house with years before the roof or the AC ever comes due. The builder's eating the cost. Let them. Option B, buy the resale. 30 grand lower basis, no new build premium to hand back when you sell. And in a soft Phoenix, your math starts from a smaller number. You pay the extra $165 a month, but you're not financing the builder's margin into your price. Option C, don't sign either one until you've run two tests. Hit pause. Pick your option. Then come back. Because option C is the one that decides it. Okay, here's how I'd size it. Start with why the builder is doing this, because that's the whole tell. To put that 5% on your loan, they're paying roughly 18 to 20 grand up front in points to the lender at closing. You never see it. You just reap it at 316 a month every month you hold. And here's the part most buyers miss. That same 20 grand handed to you as a straight discount off the price would only drop your payment about 126 a month. As a rate buy down, it drops it 316, more than twice the relief for the same money. That's why the builder reaches for a rate instead of a price cut. It's simply the more efficient tool. But there's a bigger reason underneath it, and I did a whole episode on it, the margin compression map. 11 of 11 national builders, all showing the same squeeze at the same time. When a builder's margin is that thin, they will do almost anything to avoid cutting the sticker price. Because a rate buy down is invisible, and a price cut is not, a price cut is public. It resets the recorded comps for the whole subdivision, and the next appraiser prices every neighbor lower. A buy down never touches the sale price. So the builder protects their comps and moves the house, and you get a real payment break in the bargain. Both things are true at once. A buy down can be a genuinely great deal, and it can be the cheapest way for a builder to sell without admitting the price came down. Which is exactly why you don't assume. You check. Tripwire 1. Is that 5% permanent? A permanent buy down holds for all 360 months, the whole life of the loan. But not every buy down is permanent. Some are temporary. The rate starts low and then steps up to the market rate, usually inside the first two or three years. A 2.1 buy down is the classic version. It climbs about a point a year until it hits the real note rate. So if that 5% is actually temporary and you're back at 6.5 by year three, your payment doesn't stay at 1782. It jumps to 2098. Now you're paying more than the resale you walked away from. The more expensive house and the more expensive payment. So ask one question and get it in writing. Does this rate reset ever? Tripwire 2. What does it sell for later? A new build appraises fine today. Appraisers value new construction against other new construction, but that tells you almost nothing about your exit when your house is a used build competing against next year's new subdivision down the road. So pull the real number. What do former new builds, now three to five years old, in this submarket resell for, against what they sold for new? In a metro where home values are already down about 2% this year, 1.7 to be exact, you can't lean on appreciation to erase a premium. If that resale gap is real, part of your 415 is margin you hand right back on the way out. One more quickly, because I don't want you walking away with the wrong number in your head. That 165 is a principal and interest edge. It is not your cash flow. A brand new subdivision and an established street can differ on property tax, on HOA, on insurance by more than $165 a month. A new build in Arizona gets assessed at that fresh sale price, and a lot of new subdivisions carry an HOA, the older street doesn't. So underwrite the whole picture. Underwrite the NOI, net operating income. Every expense folded in, not just the payment. And look, if you already bought a new build with a buy down, don't hear any of this as you got played. You probably didn't. A permanent buy down on a house that holds its value is one of the best deals in this market. This is about knowing your real number, the permanent one, the exit one, before you sign the next one. So here's the verdict. If the buy down is permanent and the exit comps hold, take it. Option A. And it's better than it looks. That extra six grand of down payment is buying you about $2,000 a year, a 30 plus percent return on that incremental cash if the basis holds, plus a new roof you're not replacing. But if the rate resets or that premium is real, the resale is the safer basis. A lower entry you can defend in five years beats a lower payment you can't. Your challenge this week. If a builder is waving a rate at you, ask the two questions before anything else. Does the rate reset ever in writing? And what do the used versions of this house sell for down the street? Underwrite the rate that lasts 360 months, not the one that lasts 24. The full write-up, all three options side by side, is linked right there in the show notes. The builder buy down is one of the best tools in a soft market for the investor who reads the fine print. Run the tests, then let the numbers pick. I'm Martin Maxwell.
