The Two Key Changes (Effective December 15, 2024)
| Change | Before Dec 15, 2024 | After Dec 15, 2024 | Who Benefits |
|---|---|---|---|
| Maximum insured amortization | 25 years for all insured mortgages | 30 years for first-time buyers + new construction purchases | First-time buyers + new construction buyers with < 20% down |
| Maximum insured purchase price | $1,000,000 | $1,500,000 | Buyers purchasing between $1M–$1.5M who have less than 20% down |
| Stress test rate (B-20) | Greater of: contract rate + 2% OR 5.25% | Unchanged — same rules apply | No change for stress test calculation |
| Minimum down payment structure | 5% on first $500K, 10% on $500K–$999,999 | 5% on first $500K, 10% on $500K–$999,999, 10% on $1M–$1.499M | Buyers in $1M–$1.5M range can now use insured mortgage |
Change 1: 30-Year Amortization for Insured Mortgages
Who Qualifies
As of December 15, 2024, 30-year insured amortization is available to two groups:
- First-time homebuyers: Defined as someone who has never owned a principal residence in Canada, or who has not owned a principal residence in the last 4 calendar years (the same definition used for the First-Time Home Buyers’ Tax Credit and RRSP Home Buyers’ Plan). All insured purchases by qualifying first-time buyers are eligible, regardless of property type.
- Purchasers of new construction: Anyone buying a newly constructed home — a home that has never been occupied — qualifies for 30-year amortization on the insured mortgage, even if they are not a first-time buyer. This includes presale condos upon completion, newly built detached homes, and any property sold by a developer as a first occupancy.
⚠️ Who Does NOT Qualify for 30-Year Amortization
Existing homeowners purchasing a resale property remain limited to 25-year insured amortization. If a move-up buyer with existing equity is purchasing an $800,000 resale condo with 10% down, they are not a first-time buyer and not buying new construction — the 30-year option does not apply. They must qualify on a 25-year amortization.
How 30-Year Amortization Affects Purchasing Power
Extending amortization from 25 to 30 years reduces the required monthly payment for any given mortgage balance. Because lenders qualify borrowers based on their ability to service the debt (as a percentage of gross income), lower monthly payments allow buyers to qualify for larger mortgages on the same income.
| Mortgage Amount | 25-Year Payment (5%) | 30-Year Payment (5%) | Monthly Savings |
|---|---|---|---|
| $500,000 | $2,908 | $2,674 | $234 |
| $600,000 | $3,490 | $3,209 | $281 |
| $700,000 | $4,072 | $3,743 | $329 |
| $800,000 | $4,653 | $4,278 | $375 |
| $900,000 | $5,235 | $4,812 | $423 |
| $1,000,000 | $5,817 | $5,347 | $470 |
Approximate monthly payments. 5.00% interest rate, semi-annual compounding (Canadian standard). Actual payments vary by lender.
The Stress Test Still Applies
The B-20 mortgage stress test was not changed by the December 2024 rules. Buyers are still qualified at the greater of their contract rate plus 2%, or 5.25%. This means the income required to qualify for a given mortgage amount is calculated at the stress test rate — not the actual contract rate.
However, the longer amortization still helps qualification: the stress test applies to the monthly payment for a given amortization period. A 30-year amortization produces a lower stress-test monthly payment than 25 years, even at the same qualifying rate — so more income stretches further.
Total Interest Cost: The Trade-Off
The lower monthly payment of a 30-year amortization comes at a significant long-term cost:
| Mortgage | Amortization | Total Interest (5%) | Extra Cost vs 25yr |
|---|---|---|---|
| $600,000 | 25 years | ~$448,600 | — |
| $600,000 | 30 years | ~$555,200 | +$106,600 |
| $800,000 | 25 years | ~$598,100 | — |
| $800,000 | 30 years | ~$740,300 | +$142,200 |
Approximate totals at consistent 5.00% rate. Real costs will vary with rate renewals over the amortization period.
💡 How to Advise First-Time Buyers
Frame the 30-year option as a qualification tool, not necessarily an optimal financial strategy. Buyers who can qualify at 25 years and afford the higher payment may be better off long-term. Buyers who cannot qualify at 25 years but can at 30 years have a new path to homeownership — but should understand they are paying significantly more total interest. Many buyers will use 30-year amortization to get into the market, then accelerate payments when income grows.
Change 2: $1.5M Insured Mortgage Price Cap
What Changed
Before December 15, 2024, CMHC and other mortgage default insurers (Sagen, Canada Guaranty) could only insure mortgages on properties priced below $1 million. Buyers purchasing at $1M or above were required to put down at least 20% — a conventional (uninsured) mortgage. This excluded a massive portion of BC’s housing market from insured products.
After December 15, 2024, the cap was raised to $1.5 million. Buyers can now purchase homes priced between $1M and $1.5M with as little as 10% down (subject to the minimum down payment formula below), using an insured mortgage through CMHC, Sagen, or Canada Guaranty.
Minimum Down Payment — New Formula
For properties between $1 million and $1.5 million:
- 5% on the first $500,000 of purchase price
- 10% on the portion from $500,001 to $999,999
- 10% on the portion from $1,000,000 to $1,499,999
📋 Down Payment Examples (Post Dec 15, 2024)
| Purchase Price | Min Down Payment | % of Price | Insured Mortgage |
|---|---|---|---|
| $900,000 | $65,000 | 7.2% | $835,000 |
| $1,000,000 | $75,000 | 7.5% | $925,000 |
| $1,100,000 | $85,000 | 7.7% | $1,015,000 |
| $1,200,000 | $95,000 | 7.9% | $1,105,000 |
| $1,300,000 | $105,000 | 8.1% | $1,195,000 |
| $1,400,000 | $115,000 | 8.2% | $1,285,000 |
| $1,499,999 | $124,999 | 8.3% | $1,374,999 |
Minimum down payment formula: 5% on first $500K + 10% on $500K–$999,999 + 10% on $1M–$1.5M. CMHC premium also applies on insured amount.
CMHC Insurance Premium on the Higher Cap
CMHC charges a premium on the insured mortgage amount. For mortgages with 10–15% down payment (LTV of 85–90%), the premium is 3.10% of the insured loan amount. For a $1.2M purchase with $95,000 down:
- Insured mortgage: $1,105,000
- CMHC premium: 3.10% × $1,105,000 = $34,255
- Total insured amount: $1,139,255
- The premium is added to the mortgage, not paid upfront
BC also charges PST (8%) on the CMHC premium — so on a $34,255 premium, the buyer pays an additional $2,740 in PST at closing.
Impact on the BC Market
These changes have material consequences for BC’s housing market, given that Metro Vancouver and many Vancouver Island markets regularly see properties trading in the $1M–$1.5M range:
| Impact | Details |
|---|---|
| Expands buyer pool for $1M–$1.5M properties | Buyers who previously needed 20% ($200,000–$300,000) can now enter with as little as $85,000–$125,000 down — opening townhouses, detached homes, and upper-end condos to buyers with good income but limited savings |
| Significant for Metro Van townhouses and smaller detached | Many Metro Vancouver and Fraser Valley townhouses and entry-level detached homes trade in the $1.1M–$1.4M range — previously requiring $220K–$280K down; now accessible with $85K–$120K |
| New construction demand boost | All buyers (not just first-time) can use 30-year amortization for new builds — incentivizing presale condo purchases and potentially stimulating new development demand |
| Sellers at $999K-$1.5M may see stronger buyer pools | The ceiling of the insured mortgage market moved up — sellers at $1.1M, $1.2M, and $1.3M now have access to buyers who previously could not qualify |
| Debt levels increase | Critics note the changes allow buyers to carry larger debt loads; higher total debt exposure in BC's already stretched housing market |
| Stress test unchanged — income requirements persist | The stress test still applies; buyers still need sufficient income. The change helps those with income but limited savings more than those with neither |
The RRSP Home Buyers’ Plan — 2024 Increase
The April 2024 federal budget also increased the RRSP Home Buyers’ Plan (HBP) withdrawal limit from $35,000 to $60,000 per person (effective for withdrawals made on or after April 16, 2024). For a qualifying couple, this means up to $120,000 can be withdrawn tax-free from RRSPs for a first home purchase.
Combined with the First Home Savings Account (FHSA — up to $40,000 per person), a qualifying BC couple can now accumulate up to $200,000 in tax-advantaged savings for a first home:
- FHSA: $40,000 × 2 = $80,000
- HBP from RRSP: $60,000 × 2 = $120,000
- Combined: $200,000
This stacks well with the new $1.5M cap — a couple with $200,000 in combined savings could potentially qualify for an insured mortgage on a property up to approximately $1.4M–$1.5M (depending on the down payment formula and qualification).
Qualifying a Buyer Under the New Rules: A BC Scenario
📊 Example: First-Time Buyer in Burnaby (2026)
Buyer profile: Couple, combined income $165,000/year. First-time buyers. Total savings: $120,000 (FHSA + RRSP HBP).
Target: 2-bedroom townhouse in Burnaby, listed at $1,100,000.
Down payment: $85,000 (5% of $500K = $25K + 10% of $500K–$1M = $50K + 10% of $100K = $10K)
Available savings: $120,000 — more than needed for down payment; remainder covers closing costs (PTT, legal, title insurance, CMHC PST)
Insured mortgage: $1,015,000 + CMHC premium (3.10%) = $1,046,465
30-year amortization payment (5% rate): ~$5,597/month
Stress test qualifying rate: 7% (5% + 2%). Monthly payment at 7% over 30 years: ~$6,956. Max GDS ratio 39%: max qualifying payment = $165,000 × 39% / 12 = $5,363. Note: This couple may need to qualify on income alone or reduce purchase price — run actual numbers with a mortgage broker.
Realtor Checklist: Advising Buyers on 2024 Rule Changes
When Representing a Buyer Post-December 2024:
- ✓Confirm whether the buyer is a first-time homebuyer (4-year lookback rule) — if yes, they qualify for 30-year amortization on any insured purchase
- ✓If buyer is purchasing new construction, confirm 30-year amortization is available regardless of first-time buyer status
- ✓If buyer is purchasing in the $1M–$1.5M range, confirm they can use an insured mortgage with the minimum down payment formula
- ✓Calculate CMHC premium and BC PST on premium — include in closing cost estimate
- ✓Explain the long-term interest cost trade-off of 30-year vs 25-year amortization
- ✓Advise buyer to confirm qualification with their mortgage broker using the 2024 rules — not to rely on pre-approval that may have been calculated under old rules
- ✓If buyer has RRSP savings, remind them of the $60K HBP withdrawal limit (increased from $35K in April 2024)
- ✓If buyer has or can open an FHSA, advise up to $40K can be contributed tax-free and withdrawn for first home purchase
- ✓Check provincial BC programs: BC HOME Partnership (if applicable), BC First-Time Home Buyers’ PTT Exemption
What Wasn’t Changed
Realtors should also know what the December 2024 changes did NOT affect:
- Stress test: B-20 qualifying rate unchanged — greater of contract rate + 2% or 5.25%
- Conventional (20%+ down) mortgages: No changes — buyers with 20%+ down continue on their existing framework
- Properties above $1.5M: Remain conventional-only (20% minimum down, no insurance)
- Investment properties: No change — insured mortgages require the buyer to occupy as principal residence
- Second homes / vacation properties: No change — remain conventional-only
- PTT (Property Transfer Tax): The provincial PTT rules were not changed by the federal rule updates — BC’s first-time buyer PTT exemption remains at homes priced below $835,000
Frequently Asked Questions
What were the major federal mortgage rule changes in December 2024?
Effective December 15, 2024: (1) the maximum insured amortization was extended to 30 years for first-time buyers and new construction; (2) the maximum insured purchase price cap was raised to $1.5 million.
How does 30-year amortization affect BC buyer purchasing power?
It reduces monthly payments by approximately 8-9% for a given mortgage amount, which increases the maximum mortgage a buyer can qualify for on the same income — roughly 7-10% more purchasing power, depending on income level and qualifying rate.
Who qualifies for 30-year insured amortization in BC?
First-time homebuyers (haven’t owned in last 4 years) purchasing any property, and any buyer purchasing a newly constructed home. Purchase price must be under $1.5M with less than 20% down.
Can buyers still use CMHC insurance on homes priced above $1 million in BC?
Yes — as of December 15, 2024, the insured mortgage price cap is $1.5 million. Buyers can purchase in the $1M–$1.5M range with as little as 10% down using an insured mortgage.
Does 30-year amortization cost buyers more interest over the life of the mortgage?
Yes — significantly more. On a $700,000 mortgage at 5%, the 30-year option costs approximately $120,000 more in total interest than the 25-year option. Buyers should understand this trade-off.
