Refinance cashback offers — often $2,000 to $4,000 paid to you for switching lenders — sound like straightforward free money. Attached to most of them is a clawback clause: switch away again within a set window, commonly 2-4 years, and you may have to repay some or all of that cashback. It's worth understanding before treating the headline figure as a clean win.
How Refinance Cashback Offers Actually Work
A lender offers a cash payment — commonly in the $2,000-$4,000 range, sometimes higher on larger loans — as an incentive to bring your mortgage to them. It's usually paid shortly after settlement, separate from any rate discount on the loan itself. The clawback clause, buried in the offer terms, typically requires repaying the cashback (in full or on a declining scale) if you refinance away from that lender again within the specified period.
Worked Example: Is Switching Actually Worth It?
A borrower on the $520,000 loan considering a move from 6.19% to a competitor's 5.85% rate, with a $3,000 cashback offer and a 3-year clawback:
| Factor | Value |
|---|---|
| Rate saving | 0.34 percentage points |
| Approx. monthly saving | ~$95 |
| Cashback offered | $3,000 |
| Discharge/exit fees on current loan | ~$350-$600 |
| Net benefit if staying 3+ years | Rate savings (~$1,140/year) + cashback − exit costs |
If this borrower stays with the new lender past the 3-year clawback window, the full $3,000 is genuinely kept, on top of the ongoing rate savings. If they refinance away again within that window — say, to chase another cashback deal elsewhere — some or all of the $3,000 may need to be repaid, which can wipe out much of the apparent benefit of switching at all.
Common Mistakes
Borrowers frequently focus on the cashback amount without checking the clawback window's length — a $4,000 cashback attached to a 4-year clawback is a genuinely different offer from a $2,000 cashback with no clawback at all, even though the first number looks more attractive.
Borrowers also forget to account for discharge fees on their current loan when refinancing away — these are typically modest ($350-$600) but do reduce the net benefit of switching, and are separate from any cashback or clawback consideration on the new loan.
A third mistake: chasing a cashback-heavy lender without comparing the underlying ongoing rate — a slightly higher rate paired with a large cashback can cost more over several years than a lower rate with no cashback at all, depending on how long the loan is held.
Where This Tool Has Limits
It uses a general framework — actual cashback amounts, clawback terms, and discharge fees vary significantly by lender and change frequently as lenders compete for refinance volume. It also can't predict how many times a specific borrower might realistically refinance again, which is the key variable in whether a clawback clause ever actually gets triggered.
Frequently Asked Questions
Do all refinance offers have a clawback clause?
Not all, but many do — it's specifically written into the cashback offer terms, so it's worth reading before assuming the cash is unconditional.
Is a bigger cashback always the better deal?
Not necessarily — the underlying interest rate, ongoing fees, and clawback terms all affect the real value more than the headline cashback figure alone.
Does refinancing always involve exit fees on my current loan?
Discharge fees are common and modest, but break costs can apply separately if you're exiting a fixed-rate term early — those can be considerably larger and are worth checking before committing to a switch.
How long should I plan to stay with a new lender to make refinancing worthwhile?
It depends on the specific offer, but generally long enough to clear any clawback window and recover discharge/establishment costs through the ongoing rate saving — often a minimum of 1-2 years, sometimes longer.
Can I negotiate a better rate with my current lender instead of switching?
Often worth trying first — a "retention" call asking your current lender to match a competitor's rate can sometimes achieve a similar benefit without any refinancing costs or clawback exposure at all.
