The client
An existing homeowner couple in Nova Scotia, buying a first rental — a bungalow in the Yarmouth market — without touching a dollar of savings. Instead, they drew $50,000 against a home equity line of credit already secured on their own house and used the draw as the rental’s entire down payment.
Borrowers
Existing homeowners, first rental purchase
Own home carrying costs $1,750/mo
Combined income
$114,000/year
$9,500/mo for the ratio math
Existing debt

Clean repayment history
Rental purchase
$250,000, Yarmouth
Rental property tax $215/mo; lender heat estimate $95/mo
Down payment
$50,000 — 20%, entirely a HELOC draw
Nothing from savings; rental purchases are conventional financing
The HELOC
$50,000 drawn, secured on their own home
Interest-only, 6.95% contractual rate
Two ways of pricing the same $50,000 draw — the number that decided the whole file:
| Benchmarking the open HELOC | Monthly |
|---|---|
| First lender: 3% of the amount drawn, a hypothetical worst-case payment | $1,500 |
| Second lender: the HELOC’s actual contractual payment, interest-only at 6.95% | $290 |
The problem
Borrowing the down payment did not make it free. The $50,000 the couple drew is still money owed, secured against their own home, with a real payment due every month — regardless of what it was used to buy. The first lender’s policy treated any open HELOC as if it could be redrawn to its balance at any moment, benchmarking the payment at 3% of the amount owing rather than what the credit agreement actually requires.
The first lender’s benchmark
- ▸HELOC drawn: $50,000, used as the entire down payment
- ▸Benchmarked at 3% of the amount drawn: $1,500/mo — a hypothetical figure, not the actual bill
- ▸TDS at that benchmark: 55.8% — over a 44% ceiling. Declined.
Nothing about the rental itself, the existing home, or the couple’s income changed between the decline and the approval. The only thing that moved was which figure a lender was willing to count as the HELOC’s real cost.
The numbers
This is a conventional, uninsured rental purchase at 80% LTV — no CMHC premium in play, and the 44% referenced here is this lender’s own internal ceiling.
| The rental's own structure | Amount |
|---|---|
| Rental purchase price | $250,000 |
| Down payment (HELOC draw) | −$50,000 |
| Rental mortgage (80% LTV) | $200,000 |
| Rate & payments | Figure |
|---|---|
| Contract rate — rental pricing (illustrative, not a quote) | 5.14% |
| Minimum qualifying rate — greater of contract + 2% and 5.25% | 7.14% |
| Monthly P&I at the qualifying rate | $1,418 |
| Monthly P&I at the contract rate | $1,179 |
TDS — the benchmark versus the real payment
| TDS line | 3%-of-balance benchmark | Actual interest-only payment |
|---|---|---|
| Own home costs + car loan | $2,070 | $2,070 |
| Rental carrying costs (P&I $1,418 + tax $215 + heat $95) | $1,728 | $1,728 |
| HELOC payment | $1,500 | $290 |
| TDS vs. a 44% ceiling | 55.8% ✗ | 43.0% ✓ |
Every other number in the file — the rental’s own carrying costs, the existing home, the car loan — is identical in both columns. The $1,210-a-month gap between a hypothetical worst-case benchmark and the HELOC’s real, interest-only payment is the entire swing.
The solution
A Nova Scotia mortgage broker treated the HELOC’s benchmark, not the rental’s own numbers, as the thing that needed fixing.
First, confirmed the HELOC’s actual contractual terms. The credit agreement and a current statement showed an interest-only payment on the amount drawn — a real, verifiable figure, not a lender’s hypothetical worst case.
Second, disclosed the draw up front. A borrowed down payment that shows up unexplained on a bureau pull reads as a red flag; documenting it as the funding source from the first submission removed any ambiguity about where the $50,000 came from.
Third, moved the file to a lender whose policy counts an open HELOC’s real payment. Not every lender will — confirming the benchmark convention before submitting saved a second decline.
Fourth, kept the existing home and the rental’s own figures clean. With the HELOC settled, nothing else in the file was left to second-guess.
The outcome & the closing math
Funded conventional at 80% LTV, 25-year amortization, uninsured, once the receiving lender counted the HELOC’s actual $290 monthly cost rather than a hypothetical $1,500. Yarmouth sits at the low end of Nova Scotia’s deed transfer tax range — while Halifax and most municipalities charge the 1.5% statutory maximum, Yarmouth is one of the municipalities at the 1.0% floor:
| Cash due at closing (beyond the down payment) | Amount |
|---|---|
| Yarmouth municipal deed transfer tax — 1.0% of the $250,000 purchase price | $2,500 |
| Legal fees, appraisal & adjustments | varies |
The HELOC itself is unaffected by this closing — it stays secured on the couple’s own home, at whatever balance it carries, entirely separate from the new rental mortgage. Reported HELOC balances across Canada show plenty of homeowners using exactly this kind of draw to fund a next purchase.
What to take from this file
- 01Borrowing a down payment from home equity still creates a real, ongoing liability. Count the actual required payment in TDS — it is not “free” money just because it is the couple’s own equity.
- 02A HELOC’s benchmark convention varies enormously by lender. Some count a punitive hypothetical percentage of the balance; others count the real, often interest-only, contractual payment. Confirm which applies before assuming a file works.
- 03Disclose a borrowed down payment source from the first submission. A new draw that only appears on a bureau pull, unexplained, reads as a red flag rather than a funding plan.
- 04Yarmouth’s municipal deed transfer tax sits at the 1.0% floor, a third less than Halifax’s 1.5% cap. Confirm the local rate before budgeting closing cash off a provincial-capital assumption.
