The Float-Down Option I Paid 0.25% For Never Triggered, and I'd Buy It Again
In a falling rate window I paid 0.25 points, about $1,040, for a rate lock float-down that never activated because rates refused to dip before closing. The insurance expired worthless. Yet the math on what it bought me in sleep, and what the alternative lock cost my coworker, is the reason I'd do it again. Here is the exact contract language and the decision tree I use now.
The option cost $1,040 and it never did anything. I want to start there, because everything else im about to tell you about my float-down lock is an argument in favor of a product that, measured by outcomes, did precisely nothing. On a $416,000 loan, 0.25 points up front snagged me the right to lower my locked 6.25% rate if the lender's rate sheet dropped at least 0.25 points before closing. Between March 3, when I locked, and April 22, when I closed, the rate sheet never dropped 0.25 points. It hovered. The option expired worthless, like a movie ticket for a film that got rained out.
Why did I buy it at all? Cuz of February. In February I had watched 30-year mortgage rates move about 0.4 points down across three weeks, and I was three months from closing on a refinance-and-purchase move that had taken us two years to arrange, selling a condo and buying a house in the same 60-day window. Every decision support site told me rates were "expected to drift." I had absorbed to distrust that verb. Anticipated is a word that costs nothing to print.
the february that set the price
To understand what I snagged, you hafta understand the month before. I had spent early February watching the 30-year rate slide day after day while my closing date sat a quarter out, and I nearly made the classic mistake: waiting for the bottom. A mortgage broker I trust talked me off that ledge with one sentence — "you don't have a rate problem, you have a closing-date problem" — and I locked on March 3 at 6.25% and immediately began pricing what a fall back down would do to me.
what the contract actually said, clause by clause
Before paying, I made the loan officer email me the float-down terms, and I'm glad I did, cuz the details are the product. One: the float-down could be exercised exactly once, within five business days of closing, based on the lender's own published rate sheet on that day. Two: the trigger was a full 0.25-point drop, not the average of any index, not the Freddie Mac survey. Three: the improved rate carried the same lock expiration date, so exercising it late in the window risked nothing on timing. Four: non-refundable, evidently, and it did not apply if I switched loan programs. My coworker Priya took a similar lock at another lender that spring and her version allowed the float only if the drop happened in the final 15 days, a window narrow enough to feel decorative.
watering a dead plant
I marked my calendar with three exercise dates and checked the rate sheet every morning with the discipline of a man watering a plant that had already died. April 22: the sheet read 6.125 against my 6.25. An eighth of a point. Half the trigger. The option sat there, one quarter-point short, and expired with the paperwork going through at exactly my locked rate.
the final five business days
The endgame went exactly how these things go. April 15: sheet at 6.25, no movement. April 17: 6.25. April 18, a Friday: 6.25. Monday the 21st the sheet ticked to 6.125 and I sat there doing the arithmetic of a man watching a horse lose by a nose — a full eighth, still half the trigger. Closing was the next day. The option needed a quarter and the market gave an eighth. I exercised nothing, signed everything at my original rate, and drove home feeling like the most prepared loser in the county.
the ledger that justifies a useless purchase
Here's the honest accounting. Cost: $1,040 plus four months of mild obsession. Direct benefit: zero. So why would I do it again? Two reasons, one financial and one that I've stopped pretending is separate from the financial. First, the downside scenario it insured against was large and asymmetric: a 0.5-point drop in that window would have been worth about $136 a month on my loan, $4,000-plus over three years, and the hedge cost one quarter of one percent of the loan. As insurance pricing goes, that's not outrageous. Second, and I can quantify this only loosely, I did not spend March and April refreshing rate websites at midnight or second-guessing the largest transaction of my life. My wife pointed out, correctly and somewhat cruelly, that in February I had spent three weeks unable to sleep properly over exactly this question, and $1,040 to skip that month was cheaper than the marriage counseling it might have seeded.
what priya's lock did
Priya's version deserves its own postscript, cuz its the cautionary tale. Her rate dropped 3/8 of a point in early April — inside her float window at any sane lender. But her contract only counted the final 15 days before closing, and by her final 15 days the sheet had bounced back. She paid for a float-down, watched the exact move it was built for happen outside the window, and closed at her original rate too. Two worthless options, one structural, one temporal. Read which window you're buying.
pricing against your own downside
The lesson I carry isn't "buy float-downs." It's that a lock is a position, and every position should be priced against your actual downside, not the market's. I now write down, before locking anything: what rate movement hurts me, how much, over what window, and what the hedge costs. If the hedge is under about 15% of the realistic downside and the window is longer than 30 days, I buy it and I expect it to expire worthless. that's what insurance is. My closing statement still shows the 0.25 points on line 802, and my loan officer still apologizes for it when I see her at the credit union. She shouldn't. The product did its job. The job just wasn't lowering my rate.
