Your approval is the ceiling — your budget is the number that matters
Banks approve you against the stress test — your qualifying rate plus 2 percentage points. That sets the maximum. It does not set the smart number. The smart number is the price at which your monthly carry leaves room for life: emergency savings, kids, travel, retirement contributions.
A good Coquitlam affordability conversation works three numbers in parallel: the bank's maximum, your actual comfortable carry, and your runway buffer. The answer sits somewhere inside the triangle — not at the top corner.
What the bank is calculating
Gross Debt Service (GDS)
Your housing costs as a percentage of gross income. Most lenders want this under 39%. That includes mortgage, property tax, heat, and 50% of strata fees.
Total Debt Service (TDS)
All debt obligations — housing plus car payments, student loans, credit card minimums. Lenders want this under 44%. TDS is usually the binding constraint, not GDS.
Stress-tested rate
Your contract rate + 2%, or 5.25%, whichever is higher. This is the rate your qualifying math is run against, not the rate you actually pay.
Down payment rules
5% on first $500K, 10% on next $500K up to $1M, 20% minimum above $1M. Mortgage default insurance (CMHC/Sagen) required under 20%.
What the bank is not calculating
Your life
Kids' activities, vacations, retirement contributions, meals out, car repairs. The bank's numbers assume you live in a box eating rice.
Your closing costs
PTT, legal, adjustments, insurance, title insurance — often 2–3% of purchase price. Banks do not hold this back for you.
Rate-reset risk
At renewal, rates can move. If you are at the top of your approval today, a 2% rate increase in 5 years can reshape your monthly.
Property tax surprises
Coquitlam property tax scales with assessment. A new build or a rapidly appreciating area can see real tax increases.
Coquitlam affordability by household income — honest brackets
$100K–$130K combined income: Typical realistic range for first-time buyers is $500K–$700K. Condos in Burquitlam, Coquitlam Centre, and older parts of Port Moody fit. Any number above assumes 10%+ down and no consumer debt.
$130K–$180K combined: $700K–$1.0M realistic. Townhomes enter the conversation — Westwood Plateau, Port Moody, Port Coquitlam. Condos in newer Coquitlam Centre towers work cleanly.
$180K–$250K combined: $1.0M–$1.4M. Townhomes in Burke Mountain, Westwood Plateau, Heritage Mountain. Lower-end detached in Port Coquitlam and parts of Coquitlam.
$250K+ combined: $1.4M and up. Detached in Burke Mountain, Westwood Plateau, Heritage Mountain, Port Moody.
These are first-approximation brackets, not promises. Your actual number depends on down payment, debt load, credit, and whether you are dual-income or single. See Closing Costs Guide for what sits on top of purchase price.
The smart-budget framework
The framework I walk clients through has four numbers: maximum approval, comfortable carry, closing buffer, and rate-reset buffer. Once you see all four on a page, the right price tier picks itself.
Maximum approval is what the bank says. Comfortable carry is 60–70% of that in most cases. Closing buffer is 2–3% of purchase price. Rate-reset buffer is what your carry looks like if rates are 2% higher at renewal. If any of those four numbers breaks, the purchase price is wrong.
Affordability FAQ
Should I buy at the top of my approval?
Very rarely. The top of your approval is where the stress test just barely passed. The smart move is 70–85% of max in most cases, which leaves room for life, rate resets, and the closing buffer.
How much do I need for a down payment on a $900K Coquitlam home?
Minimum is 5% on first $500K plus 10% on the remaining $400K — that is $65K minimum. Most comfortable buyers at this price put down $90K–$180K.
What is the biggest number buyers underestimate?
Closing costs. PTT alone on an $800K home is around $14K. Add legal, adjustments, title insurance, and moving, and total closing is often $18K–$24K.
How does the stress test actually affect my price?
It typically reduces your buying power by 15–20% versus what your contract rate alone would allow. That is not a rounding error — it is the difference between a $900K and a $750K home.
Should I wait for rates to drop before buying?
Rate timing is the hardest call in real estate. What matters more is your personal financial readiness and the local market at your price tier. That is usually where the right decision is made.
