Why I Borrowed $28,000 at 9.25% While Sitting on a 3.375% Mortgage

Twenty-seven thousand eight hundred fifty dollars, in blue ink on a yellow legal pad, at 6:30 in the evening on July 8, 2025. The contractor tapped the pad twice and said the kitchen start date was August 4 if I decided by Friday, cuz he had two jobs queued behind mine. I said let me think. I figured about it with a spreadsheet until 1 in the mornin'.

Savings held $19,000, short of the quote and more than I wanted pulled out of the wall at one time. A cash-out refinance quote had come back the week before: $242,000 new balance at 6.75%, $3,100 in closing costs. The mortgage underneath all of it, $214,000 at 3.375% from a November 2021 refinance, was the part nobody at the bank read willing to discuss.

The product everyone calls expensive, a HELOC at 9.25%, turned out to be the cheap one. The number that decided it was not the 9.25. It was the 3.375, the rate on the $214,000 I already owed, because a cash-out refinance would have reset every dollar of it to nearly double.

the legal pad deadline

The kitchen was a 1994 time capsule, oak everything, and the quote covered demolition, cabinets, quartz counters, flooring, and electrical for an island. Hector does not do soft deadlines. Start August 4 or drift to spring, which meant another year of the oak. I signed his quote on July 11 for $27,850 with 20% down, before I had chosen the financing, which is its own kind of confidence.

3.375 percent, untouchable

The mortgage is the asset in the room: $214,000 remaining, 3.375%, payment of $946 principal and interest, priced in November 2021 when rates sat at the floor. Nobody refinances into 6.75% to fund a kitchen unless they hafta. Resetting $214,000 of 3.375% debt to 6.75% doubles the price of money I already borrowed, and the refinance does that before it funds one cabinet. The quote was for my whole mortgage, not my kitchen.

the 6.75% quote

The refi math, run at my dining table: a new loan of $242,000, which is the $214,000 balance plus the $28,000 kitchen, at 6.75% over 30 years prices $1,570 a month. My current payment is $946. The difference is $624 a month, every month, plus $3,100 in costs on day one, and the clock on that payment runs 30 years. Even selling in five years, the extra payments alone total $37,440, and the rate on my 2021 money sits doubled the whole time I hold the loan.

two amortizations on one page

So I put both loans on one page, all the way down. Cash-out refi: $1,570 a month for 360 months, $3,100 in costs, total interest about $323,000. HELOC: $28,000 drawn at 9.25%, interest-only minimum of $216, my planned payment $2,100 on the 25th. Payoff at $2,100 a month: 14 months, interest approximately $1,530. One option charged me for the kitchen. The other charged me for the kitchen and repriced the house.

the ugly 9.25

A 9.25% rate deserves the flinch, so let the flinch happen and then price it. Interest-only on $28,000 at 9.25% is $216 a month, which is $448 less than the refi would have added, and my plan was never the minimum. Closing costs on the line: $75, waived under a credit-union promotion, plus an appraisal waiver because the county had me at $389,000 against a $214,000 balance. Idaho Central Credit Union approved a $60,000 line. I took $28,000 and left the rest untouched.

what floating to 11 would have cost

The rate is variable, which is the honest objection to the whole plan, so I priced that too. If the margin had climbed and the rate hit 11% while I carried the average balance of my 14-month payoff, the added interest across the whole draw totals about $200. At month 25 it would have been a problem. At month 14 it is a rounding error. Speed was the hedge.

$2,100 on the 15th

The $2,100 came from three places, which is the honest version: $489 redirected from a Corolla payment that ended in June 2025, $500 to $700 from weekend photo gigs for a soccer club I had been shooting anyways, and the rest out of the checking buffer. First draw July 18, 2025, $14,000 to Hector's supplier. Second draw July 28, the balance. Thirteen drafts of $2,100 have gone out as of September 10, and the balance stands at $2,230.

change orders: $290 of hinges

The final invoice came in at $28,140, cuz my wife wanted soft-close hinges on all 19 drawers and doors, and Hector was right that we would never notice the $290 after using 'em once. That rode on the line with the second draw. The kitchen finished October 3, 2025, four days late, and the first meal cooked in it was eggs at 10 at night on paper plates because the boxes were still sealed.

fourteen months, on schedule

The final draft goes out September 25 and closes the line, fourteen months after the first dollar moved. Total interest across the whole exercise: about $1,530. Total fees: $75. Set that next to the refi quote one more time, $1,605 of borrowing cost against $3,100 plus $624 a month for 30 years, and the flinch at 9.25% looks like what it was, a reaction to a headline number instead of a read of the contract.

what the kitchen cost all-in

All-in, the kitchen cost $29,745: $28,140 of construction and hinges, $1,530 of interest, $75 of fees, funded without touching a mortgage that still prints 3.375. The legal pad is still in the drawer under the phone charger, blue ink and all, and the number that mattered was never the one Hector tapped. The mortgage underneath the new counters still says 3.375. That is it. That was the whole decision.
