The client
Permanent residents who bought their first home two years ago using alternative credit history — rent and utility payment records, since neither had a Canadian bureau file yet — are back for a second purchase in Calgary, this time on a standard bureau-based file.

The problem
The first file was won on alternative credit — twelve months of rent and utility payment history standing in for a bureau report neither borrower had yet, backed by strong down payment savings and clean employment income.
Two years and one mortgage later, the question for this second file is a different one entirely: does the file still need an alternative-credit case made for it, or does the bureau file built since then stand on its own?
The numbers
At 35% down this file is uninsured — no default-insurance premium, and no CMHC ratio ceiling to test against.
| The uninsured structure | Amount |
|---|---|
| Purchase price | $625,000 |
| Down payment (35%) | −$218,750 |
| Mortgage (uninsured, LTV under 80%) | $406,250 |
| Rate & payments | Figure |
|---|---|
| Contract rate (illustrative, not a quote) | 4.89% |
| Minimum qualifying rate | 6.89% |
| Monthly P&I at the qualifying rate (30-year amortization) | $2,647 |
| Monthly P&I at the contract rate | $2,142 |
Because the file is uninsured, it is not limited to the insured 25-year standard, and it is not bound by the insured 30-year amortization test that requires a first-time buyer or new build — a 30-year uninsured amortization was available outright.
TDS comes to 27.6% against combined income — comfortably serviceable, though on an uninsured file this is informational rather than a pass/fail line against a regulatory ceiling.
The solution
A mortgage associate licensed with Alberta’s RECA underwrote this file the same way any standard uninsured purchase gets underwritten — on the strength of the credit score and bureau history built since the first purchase, with no alternative-credit case required this time.
The bureau file itself did the work: 24 months of on-time payments on the first mortgage, plus two credit cards opened and managed cleanly since landing, brought the score to 715 — solidly in range for standard uninsured underwriting.
The outcome
Approved and funded: uninsured, 30-year amortization, 5-year fixed term. For contrast, an insured file at this price would need only $37,500 minimum down — against the $218,750 actually put down, which is what took the file out of default-insurance territory altogether.
This file also illustrates the arc a newcomer file often takes: alternative credit gets a first purchase across the line, and the tradeline that purchase creates is frequently what makes the second purchase a standard file.
What to take from this file
- 01Alternative credit is a bridge, not a permanent structure. The first purchase’s mortgage tradeline is often what lets the second purchase run as a standard bureau-based file.
- 02A large down payment does more than avoid default insurance. At 35% down, this file skips both the premium and the insured ratio ceiling entirely.
- 03Uninsured amortization rules are different from insured ones. The insured 30-year test’s first-time-buyer/new-build condition simply doesn’t apply once a file is uninsured.
- 04Ask what changed since the last file, not just what the numbers say today. The bureau history built since the first purchase was the entire story on this one.

Illustrative in this file — lender-specific, not rules:
- ▸4.89% contract rate — rates move daily; not a quote.
- ▸the TDS figure — this file is uninsured, so there is no CMHC ratio ceiling — the number is informational, not a pass/fail line.
