The Situation

Our client, a single parent of two children aged 10 and 12 who live with the client, has worked part-time hours for one engineering employer for twelve years, earning about $127,000, to be home for the children. With an 834 credit score and savings of about $424,000, the client wanted a three-bedroom condo in New Westminster priced at about $600,000.

The Challenge

Part-time employment and support payments to a former partner can give a lender pause, even when the income and the savings are strong.

The Solution

In 2024 we placed a mortgage of about $300,000 with a major Canadian bank, 50% of the price, on a five-year variable term at about 7% at the time. The bank read twelve years of part-time tenure as stable income, and the half-down purchase came from the client's savings, keeping the debt-service ratios at about 41%.

The Outcome

A three-bedroom home close to transit and amenities for the family, on a payment one part-time income carries comfortably.

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

Contract vs stress-test payment
