Buy Down Your Rate Now or Refinance Later? How to Decide
Paying for a permanent buydown and refinancing later are not opposites — the real question is whether the points pay for themselves before the loan goes away.
TL;DR
- Buying points is a bet on how long this specific loan survives, not a bet on where rates go.
- A permanent buydown places no restriction on refinancing. Refinancing early simply strands the unrecovered part of what you paid.
- Typical breakeven on a permanent buydown lands near 55 to 70 months, so a refinance or sale inside two years usually turns the buydown into a loss.
- A refinance is not free. Closing costs, a new 30-year clock, and a higher balance all eat into the payment drop.
- If you think there's a strong chance of exiting the loan quickly, lender credits — the mirror image of points — are the structure that matches that view.
Rates settling at short-term lows tends to revive this exact question at the closing table. Nobody can tell you where rates go next, so the decision has to rest on things you can actually estimate: what the points cost, what they save per month, what a refinance would cost, and how long you realistically keep the loan.
What a permanent buydown actually is
A discount point costs 1% of the loan amount and buys a permanently lower note rate. Unlike a temporary 2-1 or 1-0 buydown, which subsidizes the payment out of an escrowed fund while the note rate stays put, a permanent buydown changes the contractual rate for the life of the loan.
Two properties matter for this decision:
- The cost is sunk at closing. Points are earned when the loan funds. There is no proration, no refund, no credit back if you refinance in month 14.
- The benefit accrues monthly, forever, until the loan ends. "Ends" includes refinancing, selling, or paying off — all three stop the meter.
That framing collapses the whole comparison into one question: does the monthly benefit run long enough to repay the upfront cost? Our discount points explainer covers the mechanics in isolation; what follows is the comparison against the wait-and-refinance alternative.
Two paths, priced side by side
Take a hypothetical $400,000 conventional 30-year fixed loan. These rates are illustrative, not quotes.
Structure | Upfront cost | Note rate | Monthly P&I | Savings vs par
Par (no points) | $0 | 6.750% | $2,594 | —
1 point | $4,000 | 6.500% | $2,528 | $66/mo
2 points | $8,000 | 6.250% | $2,463 | $131/mo
1 point lender credit | –$4,000 | 7.000% | $2,661 | –$67/mo
Simple breakeven on 2 points: $8,000 divided by $131 is about 61 months, or a bit over five years. That number is the anchor for everything else. Rate-sheet pricing varies daily and by lender, so run this table with your own loan estimate rather than these figures.
Recovery by exit month
The breakeven month is not a cliff — it's a slope. Here is how much of the $8,000 comes back depending on when the loan ends, ignoring the small extra principal paydown for the moment.
Loan ends at month | Payment savings recovered | Unrecovered
12 | $1,572 | $6,428
24 | $3,144 | $4,856
36 | $4,716 | $3,284
48 | $6,288 | $1,712
61 | $7,991 | ~$0
96 | $12,576 | +$4,576 ahead
120 | $15,720 | +$7,720 ahead
Refinancing at month 24 does not "waste $8,000" — it wastes about $4,900. That distinction matters, because the alternative path was not free either.
What the future refinance really costs
Borrowers who plan to skip points and refinance later often model the refinance as a costless rate swap. It isn't.
- Closing costs come back. Lender fees, appraisal, title, recording, and prepaids apply again. The Consumer Financial Protection Bureau describes refinance closing costs as generally comparable to purchase closing costs.
- The clock resets. A new 30-year term after two years of payments means 32 total years of interest unless you shorten the term, which raises the payment and shrinks the apparent win.
- The balance can grow. Rolling costs into the loan is convenient and quietly increases what you owe. A no-closing-cost refinance trades those costs for a higher rate — the cost doesn't disappear, it changes shape.
- Qualifying is not guaranteed. Income, employment, credit, and appraised value all get re-examined. A job change, a new car loan, or a soft appraisal can close the window even when rates cooperate.
- The rate has to move enough. Our refinance breakeven guide walks through why a small drop often fails to clear the cost hurdle.
Worked example: the month-20 refinance
Same $400,000 loan, two borrowers, identical in every way except structure. Assume rates improve and both refinance into a 5.75% 30-year at month 20, rolling $5,500 of costs into the new loan.
Path A: 2 points | Path B: par, refi later
Cash at closing for rate | $8,000 | $0
Payment months 1–20 | $2,463 | $2,594
Total paid months 1–20 | $57,260 | $51,880
Balance at month 20 | ~$392,000 | ~$392,700
New loan after refi | ~$397,500 | ~$398,200
New payment | ~$2,320 | ~$2,324
Path A is roughly $5,380 more out of pocket and ends up about $700 lower in balance with a $4 monthly edge. Net, Path A is around $4,700 behind — and recovering that at $4 a month is not a real recovery.
Now flip the assumption. No refinance ever materializes and both borrowers hold eight years:
- Path A saves $131 a month for 96 months: $12,576
- Path A's faster amortization leaves about $3,483 more equity
- Against the $8,000 cost, Path A is ahead by roughly $8,000
Same two borrowers, same loan, opposite outcomes — decided entirely by whether the loan lasted.
Weighing the odds without predicting rates
You cannot forecast rates, but you can price your own beliefs. Using the numbers above, the buydown's value depends on the chance you exit within two years:
Chance of exiting within 24 months | Expected value of 2 points
10% | about +$6,800
30% | about +$4,200
50% | about +$1,600
70% | about –$1,000
90% | about –$3,600
The crossover sits near 62%. Put plainly: the buydown only turns negative if you believe there's better than a roughly two-in-three chance this loan is gone inside two years. That's a demanding bar, and it's worth checking against the things that actually drive early payoffs — a job relocation, a planned move, an ARM converting, an FHA loan you intend to refinance out of once MIP becomes the binding cost, or a purchase you already consider a two-year stepping stone.
Concrete signals that push toward skipping points:
- You expect to move or sell within three years
- Cash reserves are thin and $8,000 at closing would leave you without a cushion
- You are in a bridge structure or an ARM you intend to replace
- The seller is offering concessions that a temporary buydown or closing-cost credit would use more efficiently
Signals that push toward paying points:
- This is a long-term primary residence with no move on the horizon
- Your credit and equity are strong today, so a future refi has limited additional room to help
- The payment reduction is what makes the affordability math work at all
- You have cash beyond reserves and no higher-return use for it
Lender credits: the structure that matches a refi plan
If you genuinely believe the loan is short-lived, the honest expression of that view is not merely skipping points — it's taking a lender credit. Accepting a rate above par produces a credit that offsets closing costs, which is exactly what you want if the loan is temporary.
On the $400,000 example, a 7.00% rate producing a $4,000 credit costs $67 a month. Held 24 months, that's $1,608 in extra interest against $4,000 in cash preserved — a net gain if the loan really does end early, and a net loss if it doesn't. Credits and points are the same trade run in opposite directions, and the same breakeven arithmetic governs both.
One caution: a higher rate raises your qualifying payment. A credit can cost you DTI headroom you need for approval, and on a jumbo or high-balance file it can matter more than the cash. If you are near a conforming limit or a DTI ceiling on a conventional loan, price both versions before choosing.
Questions to put to your loan officer
Ask for these in writing, on the same day, at the same lock period — pricing changes daily, so a comparison assembled across a week is not a comparison.
- Show me par, one point, two points, and a one-point credit, with the payment and the total cash to close for each.
- What is the simple breakeven in months for each point option?
- If I refinance in 18 months, what is my net position under each?
- Do you offer any refinance-cost credit or retention program, and is it documented?
- What would this look like on a 25-year or 20-year term instead of buying the rate down?
That last question matters more than most borrowers expect — a shorter term often delivers more lifetime interest savings per dollar than points do, at the cost of a higher required payment.
