The client
A buyer purchasing a tenanted $360,000 rental property in Sarnia at 20% down, with a sitting tenant paying $1,950/mo.
Purchase price
$360,000, Sarnia
20% down, conventional rental purchase
Documented monthly rent
$1,950
Purchase-price holdback
$2,200
Pending the seller's final, unpaid water bill
Buyer's own income
$7,200/month
The problem
The seller's final water/utility bill for the property was not available by closing day -- an ordinary timing gap, but one the agreement of purchase and sale had to solve for before the deal could close on schedule.
Whose money sat in trust, and why
- ▸The final water bill would only be known once the utility issued it after the seller's move-out -- a document that simply did not exist yet
- ▸The purchase agreement's own solution was a $2,200 holdback, retained in the buyer's lawyer's trust account out of the seller's own sale proceeds
- ▸The holdback was never part of the mortgage advance -- it came out of money that would otherwise have gone to the seller at closing
Nothing about the mortgage itself was uncertain. What was uncertain was a bill that hadn't been issued yet, and whose money would cover it.
The numbers
Because the holdback came from the seller's own proceeds, it never touched the mortgage math -- the rental purchase qualified on its own terms, holdback aside.
| The rental purchase, holdback aside | Amount |
|---|---|
| Down payment (20%) | $72,000 |
| Base mortgage | $288,000 |
| Total debt service | Figure |
|---|---|
| Payment at the qualifying rate (7.10%), 25 years | $2,035/mo |
| Property tax | $285/mo |
| Heat (lender estimate) | $110/mo |
| Rental income add-back (50% of $1,950/mo) | $975/mo credited to income |
| Total debt service ÷ ($7,200 income + $975 add-back) | 32.5% |
32.5% is the same whether or not the $2,200 holdback exists -- the holdback is a closing-adjustment matter between buyer and seller, entirely separate from what the mortgage itself needed to qualify.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act confirmed with the lender, in writing, that the holdback would not affect funding before letting the closing proceed on that basis.
First, had the buyer and seller sign a specific holdback agreement, naming the $2,200 figure, the release condition (the paid final water bill), and a default if the bill did not arrive within a set window.
Second, confirmed with the lender that the mortgage would fund in full at closing regardless, since the holdback was carved out of the seller's own proceeds, not the mortgage advance itself.
Third, had the buyer's lawyer hold the $2,200 in trust, releasing it only against the actual paid bill or the agreement's own default terms -- the same kind of adjustment most files handle through the ordinary closing-costs statement of adjustments, just isolated into its own holdback.
The outcome
The purchase funded at 5.10%, with total debt service of 32.5%; the $2,200 holdback released to the seller three weeks later once the final water bill was paid and produced.
Because this file is uninsured, CMHC's ratio maximums do not apply directly; the 32.5% figure is informational.
What to take from this file
- 01A purchase-price holdback is a closing adjustment between buyer and seller, not a mortgage shortfall. Confirm with the lender specifically whether it affects funding before assuming it does.
- 02Document the holdback in its own signed agreement, naming the exact amount, the release condition, and a default -- not a verbal understanding between the parties.
- 03A holdback funded from the seller's own proceeds does not reduce what the buyer needs to close with. The buyer's own cash-to-close is unaffected by money that was never coming to them anyway.
- 04Confirm the release trigger is something that will actually happen. A holdback tied to a document with a known, if delayed, arrival date -- like a final utility bill -- resolves itself; make sure the agreement says what happens if it doesn't.
