The Situation

A married couple of scientists, permanent residents since August 2023, had bought a home and a Coquitlam rental condo that fall, then went for a third property: a one-bedroom Coquitlam condo at about $490,000, to rent at about $2,400 a month.

The Challenge

Counting both earlier mortgages, about $700,000 and about $420,000, salaries of about $100,000 and about $99,000 put the total debt-service ratio at about 50%, which needed an exception.

The Solution

In 2023 we placed about $390,000 with a major Canadian bank, 80% of the price, on a four-year fixed term at about 6.7% with a 30-year amortization. We asked for the exception on incomes with room to grow, reasonable purchase prices and rents higher than ever; the bank's rental policy counted the condo's tax, strata fees and heat at $1 each, and scores of 754 and 786 carried the file.

The Outcome

Exception made, the couple ended 2023 owning their home and two rental condos.

Two ways to buy

Same income, same down payment — two strategies. Insured pricing assumed ~0.25% below conventional.

Conventional
20% down (uninsured)
$500,000
Down: $100,000 (20.0%)
Mortgage: $400,000
Rate assumed: 4.75%
Monthly payment
$2,075/mo
Principal & interest at 4.75% over 30-yr amort
Saves $19,796 in CMHC premium
− Extra interest @ +0.25% over 5-yr term: $4,750
Est. net savings: $15,046

Limited by 20% down rule — extra income capacity is unused.

Insured
Less than 20% down (CMHC-insured)
$738,567
Down: $100,000 (13.5%)
Mortgage: $638,567
Rate assumed: 4.50%
Monthly payment
$3,320/mo
Principal & interest at 4.50% over 30-yr amort
+ CMHC premium: $19,796 (financed)
Total loan w/ premium: $658,363
30-yr insured amort (first-time buyers / new builds only) adds a 0.20% premium surcharge — not included above.

Limited by income — your cash covers more than the minimum down at this price.

What this calculator does that most don't
  • Models liabilities the way lenders actually do: credit cards at 3% of balance, student loans at 1–1.5% of balance even on $0 payment plans
  • A multi-property builder that applies 100% rental add-back to income and full carrying costs to TDS — portfolio buyers get real numbers
  • Compares insured vs conventional side by side, netting the CMHC premium saved against the extra interest of the higher conventional rate
  • Discloses the exception ratios brokers actually place files at: A-lenders to 50/50, alternative lenders to 60/60 — numbers no bank calculator will print
