A hybrid ARM is fixed for its initial five or seven years, then adjusts on a set schedule, and the fees for a lower rate work the same way they do on a fixed loan: points. The part that surprises most people: at zero points, a hybrid ARM and a 30-year fixed usually quote very close to each other. The ARM is not automatically cheaper at par. Where the difference shows up is how points behave. A point spent on an ARM buys the rate down further than the same point spent on a fixed loan, because lenders assume ARM borrowers will not pay that interest for the full 30 years, so they give up more rate per point. That mechanism is real. Our lean, though, is against paying points as a default; the zero-point quote is the honest baseline, and a buydown has to clear a break-even you genuinely expect to reach. The ARM-with-points math is something some people want to see, and we will run that comparison for you. Two context notes: ARMs are more common and more attractive in the jumbo space, and how well they price against fixed loans shifts as the yield curve flattens or steepens. Whether a 5- or 7-year ARM beats a fixed for you comes down to how long you plan to hold the loan, which is exactly what we map out on a Roadmap conversation.
