The client
A separating Carleton Place couple holds a $540,000 matrimonial home against a $280,000 joint mortgage. Negotiating the buyout took 14 months, during which the remaining spouse lived in the home alone.

The problem
Both spouses had priced the buyout as a straightforward half of net equity. What the separation agreement's occupation-rent clause added was a real, dollar-for-dollar credit owed to the departing spouse for the 14 months the remaining spouse had exclusive use of the home while the buyout itself was still being negotiated.
Why occupation rent grows a buyout, not shrinks it
- ▸Occupation rent compensates the departing spouse for the other spouse's continued, exclusive use of a jointly-owned home
- ▸It is calculated separately from the equity split, then added to whatever the departing spouse is already owed
- ▸The longer a buyout takes to negotiate, the larger the occupation-rent credit grows -- it is not a one-time, fixed amount
This runs the opposite direction from most of the adjustments a buyout refinance has to price in -- a pension credit, an appraisal shortfall, or a documented premarital exclusion typically reduce what's owed; occupation rent increases it.
The numbers
Once the occupation-rent figure was confirmed in writing, sizing the refinance to the real, larger buyout was straightforward.
| The naive half vs. the buyout with occupation rent included | Amount |
|---|---|
| Home value at separation | $540,000 |
| Existing joint mortgage | $280,000 |
| Net equity | $260,000 |
| Naive 50/50 half | $130,000 |
| Occupation rent ($1,400/mo × 14 months) | +$19,600 |
| Total buyout owed | $149,600 |
| Sizing the refinance | Figure |
|---|---|
| Refinance needed (existing balance + buyout) | $429,600 |
| Minimum qualifying rate on a 5.05% contract rate | 7.05% |
| Qualifying payment, 25 years | $3,022/mo |
| TDS (payment + $300 tax + $130 heat + $250 car loan) ÷ $8,900 income | 41.6% |
Without the occupation-rent credit, the refinance would have been $19,600 smaller, and TDS proportionally lower -- but that smaller figure would have shorted the departing spouse of a real, agreed amount. TDS here is informational only, since this uninsured refinance carries no CMHC ratio ceiling, and the payment itself sits well within what average mortgage payments across Canada look like today.
The solution
Family counsel and a mortgage agent treated occupation rent as its own line item to confirm, not an estimate to fold into the equity split.
First, confirmed the occupation-rent rate and the exact number of months in the separation agreement itself. $1,400/month, for the 14 months between separation and the buyout's closing.
Second, calculated the occupation-rent total separately, then added it to the naive equity half. $19,600 on top of $130,000, not folded into a single re-estimated number.
Third, sized the refinance to the full $429,600 -- existing balance plus the complete buyout -- from the first conversation. A refinance sized to the naive half alone would have left the departing spouse owed money the new mortgage never raised.
The outcome
The refinance funded at 5.05%, covering the existing balance plus the full $149,600 buyout with occupation rent included. TDS settled at 41.6%, comfortably inside this lender's own comfort ceiling.
How occupation rent is calculated, and whether it applies at all, depends on the separation agreement or a court order -- it is not automatic, and the rate and period here are specific to this file.
What to take from this file
- 01Occupation rent increases a buyout; most adjustments shrink one. A pension credit, an appraisal shortfall, or a documented exclusion typically reduce what's owed -- occupation rent is one of the few that adds to it.
- 02The longer a buyout takes to negotiate, the larger an occupation-rent credit can grow. Time itself is a cost variable here, not just a delay.
- 03Confirm the rate and the period in writing, from the agreement itself. An estimate folded into the equity split risks under- or over-stating what's actually owed.
- 04Size the refinance to the full, combined figure from the first conversation. A mortgage sized to the naive half alone leaves a real, agreed amount unfunded.
- 05Ask how long a buyout has actually taken to negotiate. Occupation rent is easy to overlook when the focus is on the equity split alone.
