The client
An investor in Hawkesbury refinanced a rental property currently worth $430,000 to fund the down payment on a second rental, breaking the existing 4.45% mortgage two years before its term ends.
Original mortgage advance, 5 years ago
$310,000
True current outstanding balance
$276,500
After 5 years of regular amortization payments
Contract rate
4.45%
2 years remaining
Current comparison rate
3.95%
The problem
Five years of regular payments had brought the true balance on this mortgage down to $276,500 -- but the payout statement's interest-rate-differential penalty was calculated against the mortgage's original $310,000 advance from five years ago, a balance that no longer existed anywhere except in an outdated file note.
The base the payout statement should have used
- ▸The mortgage's own current statement shows $276,500 outstanding, after five years of regular payments with no lump sums
- ▸The payout statement's own IRD calculation was run against the original $310,000 advance instead
- ▸A penalty calculated against a larger, obsolete balance is a larger penalty than the mortgage actually supports
Nobody disputed the 0.50-point rate differential itself. The balance it was multiplied against was simply five years out of date.
The numbers
Running the identical differential against the true current balance, rather than the original advance, is the entire source of the $336 gap.
| The penalty, on two different balances | Amount |
|---|---|
| Penalty on the original $310,000 advance | $3,096 |
| Penalty on the true $276,500 current balance | $2,760 |
| Amount overstated | $336 |
| Refinance available | On the overstated penalty | On the correct penalty |
|---|---|---|
| Maximum new mortgage (75% of $430,000 value) | $322,500 | $322,500 |
| Payout to the existing lender | $279,596 | $279,260 |
| Cash available for the second property's down payment | $42,904 / $43,240 |
The $336 gap moves dollar for dollar into the cash available for the second rental's down payment -- a margin worth protecting given how tight rental vacancy rates keep this kind of second-property plan under time pressure. The maximum new mortgage does not change, only how much of it goes to retiring the first one correctly.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act pulled a current mortgage statement rather than relying on the payout statement's own stated balance.
First, pulled a current mortgage statement showing the true, paydown-reduced $276,500 balance.
Second, confirmed with the outgoing lender's discharge desk that the payout statement's IRD calculation had been run against the original $310,000 advance in error.
Third, had the penalty recalculated against the true $276,500 balance, before the refinance was sized.
The outcome
The refinance funded at $322,500 (75% of the property's $430,000 value), leaving $43,240 in cash for the second rental's down payment once the corrected $2,760 penalty was deducted, at total debt service of 33.6%.
Because this file is uninsured, CMHC's ratio maximums do not apply directly; the 33.6% figure is informational, and the 75% loan-to-value ceiling is this lender's own uninsured-rental-refinance policy, not a CMHC-published rule.
What to take from this file
- 01An interest-rate-differential penalty should be calculated against the mortgage's true current balance, not its original advance amount from years earlier. Pull a current statement rather than relying on a file note.
- 02A payout statement's own stated balance can be wrong in a way the ratios will never catch. $310,000 and $276,500 both produce plausible-looking totals.
- 03An overstated penalty on a refinance comes directly out of the cash available to the borrower. On this file, dollar for dollar.
- 04Five years is long enough for a file note to go stale. Verify the current balance independently on any mortgage this far into its life.
