The problem
A deposit wired from a joint account proves the money left that account -- but it proves nothing about whose money it actually was, when the account is shared with someone who is not part of the purchase at all.
What a joint account alone could not settle
- ▸The $75,000 deposit was wired from an account jointly held by the buyer and their parent
- ▸The parent is not a purchaser, is not going on title, and is not on the mortgage application
- ▸A joint account by itself does not establish whether the money was the buyer's own funds sitting in a shared account, or effectively a gift from the parent
The wire itself was not in question. Whose money it actually represented was.
The numbers
Once the deposit's ownership was documented, qualifying the rental purchase on the buyer's own income plus a standard rental add-back was straightforward.
| The rental purchase, deposit ownership confirmed | Amount |
|---|---|
| Down payment (20%) | $75,000 |
| Base mortgage | $300,000 |
| Total debt service | Figure |
|---|---|
| Payment at the qualifying rate (7.15%), 25 years | $2,129/mo |
| Property tax | $295/mo |
| Heat (lender estimate) | $115/mo |
| Rental income add-back (50% of $2,100/mo) | $1,050/mo credited to income |
| Total debt service ÷ ($7,400 income + $1,050 add-back) | 32.5% |
32.5% leaves comfortable room on a conventional rental purchase -- the ratios were never in doubt once the deposit's ownership, not the arithmetic, was resolved.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the joint-account deposit as a source-of-funds question requiring its own documentation, not an assumption either way.
First, obtained a signed gift letter from the parent confirming the wired funds were a gift to the buyer alone, with no claim on the property and no expectation of repayment.
Second, pulled several months of the joint account's own statements, showing the buyer's regular deposits into that account before the withdrawal -- evidence the account held the buyer's own money as well as the parent's.
Third, documented the deposit as the buyer's own funds, gifted portion included, rather than leaving the file to guess at an unexplained joint-account withdrawal.
The outcome
The rental purchase funded conventionally at 5.15%, with total debt service of 32.5% once the deposit's true ownership was documented.
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 joint account proves the money left that account -- nothing more. It does not, by itself, establish whether a co-holder has any claim to the funds withdrawn.
- 02When a joint co-holder is not part of the purchase, get a signed statement addressing the specific withdrawal. A general assumption that shared funds are automatically the buyer's own is not documentation.
- 03A joint account's own deposit history can help establish whose money is really in it. Showing the buyer's own regular deposits supports the claim that at least part of the withdrawal was already theirs.
- 04Treat a joint-account withdrawal the same way as any other unexplained deposit until it is documented. The account structure itself is not proof of ownership.

- ▸5.15% contract rate — rates move daily; not a quote.
- ▸the 50% rental add-back — each lender publishes its own treatment of rental income; there is no universal rule.
- ▸the TDS figure — this is a conventional rental purchase at 20% down -- there is no CMHC ratio ceiling; the number is informational.
