High-Ratio vs Conventional Mortgages BC: Complete Guide (2026)

TL;DR

According to CMHC, high-ratio mortgages require less than 20% down but add insurance premiums of 0.60% to 4.00%. Conventional mortgages avoid insurance costs but need larger down payments. Most first-time buyers in BC choose high-ratio financing.

Key Takeaways

Down Payment Threshold — High-ratio mortgages require less than 20% down while conventional mortgages need 20% or more
Insurance Requirements — High-ratio mortgages must include CMHC, Sagen, or Canada Guaranty insurance adding 0.60% to 4.00% to your loan
Qualification Standards — Both mortgage types face the same stress test, but conventional mortgages offer more lender flexibility

When I sit down with clients in Coquitlam, one of the first questions they ask is whether they should put down 5% or 20% on their home purchase. This decision determines whether you'll need a high-ratio or conventional mortgage, and the choice impacts everything from your monthly payments to your total borrowing costs. According to CMHC, mortgage default insurance premiums range from 0.60% to 4.00% of the insured amount, making this one of the most financially significant decisions in your home buying journey. In BC's expensive housing market, where the average home price exceeds $900,000, understanding these mortgage types can save you thousands or help you enter the market sooner. I've guided many clients through this decision, and the right choice depends on your financial situation, timeline, and long-term goals.

Quick Comparison: High-Ratio vs Conventional Mortgages

High-ratio mortgages win for accessibility while conventional mortgages win for long-term cost savings. The exception is when you're buying an investment property, where high-ratio financing isn't available. Here's how these mortgage types stack up across key dimensions:

Category	High-Ratio Mortgage	Conventional Mortgage
Best For	First-time buyers, limited savings	Established buyers, lower total cost
Down Payment	5% to 19.99%	20% or more
Insurance Required	Yes (0.60% to 4.00%)	No
Maximum Purchase Price	$1 million	No limit
Lender Options	All major lenders	All lenders plus private
Investment Properties	Not available	Available
Our Verdict	Best for market entry	Best for total savings

In Coquitlam's market, I've seen many Burke Mountain buyers choose high-ratio mortgages to enter sooner rather than wait years to save a full 20% down payment. According to the Financial Consumer Agency of Canada, both mortgage types face the same stress test requirements, qualifying at the greater of your contract rate plus 2% or 5.25%. The key difference lies in the upfront costs and long-term financial impact.

Which Mortgage Type Wins on Total Cost?

Conventional mortgages win decisively on total cost, but high-ratio mortgages often make financial sense despite the insurance premium. Let me break down the real numbers from a typical Coquitlam purchase.

Consider a $800,000 home purchase in Port Moody. With a conventional mortgage at 20% down ($160,000), you avoid insurance premiums entirely. Your mortgage amount is $640,000 with monthly payments around $3,200 at current rates. With a high-ratio mortgage at 10% down ($80,000), your mortgage amount jumps to $720,000 plus a CMHC premium of 2.40% ($17,280), for a total loan of $737,280. Monthly payments climb to approximately $3,700. Over 25 years, the conventional mortgage saves roughly $150,000 in total payments. However, according to Statistics Canada, average home prices in Metro Vancouver increased 43% between 2018 and 2023. If you spent two years saving the additional $80,000 for a conventional down payment, that same $800,000 home might cost $900,000 or more. The opportunity cost of waiting often exceeds the insurance premium savings. I've seen this play out repeatedly with clients in Westwood Plateau and Town Centre areas, where rapid appreciation made early entry more valuable than perfect financing. What surprised us was how many buyers who started with high-ratio mortgages successfully refinanced to remove insurance premiums within five years through appreciation and principal paydown.

Who Should Choose High-Ratio vs Conventional Mortgages?

Choose high-ratio financing if you're a first-time buyer with limited savings or buying in an appreciating market where timing matters more than cost optimization. The decision often comes down to opportunity cost versus total cost. **First-time buyers with 5-15% saved:** High-ratio mortgages let you enter the market immediately rather than rent for years while saving more. In Coquitlam's rental market, you might spend $2,500 monthly on rent instead of building equity. According to the CRA, the FHSA allows $8,000 per year to a $40,000 lifetime maximum, making high-ratio financing attractive while you build FHSA contributions. **Established buyers with 20%+ available:** Conventional mortgages make sense when you have sufficient down payment funds without compromising your emergency reserves. You'll save significantly on insurance premiums and often access better rate negotiations. **Investors and second-home buyers:** You must choose conventional financing since high-ratio mortgages aren't available for investment properties. This is where I often recommend exploring our investment property financing options, including alternative lenders who specialize in rental property purchases. Here's the edge case most buyers miss: if you're purchasing a property over $1 million, high-ratio financing isn't available regardless of your down payment percentage. In Maillardville or Burquitlam, where detached homes increasingly exceed this threshold, you'll need conventional financing even with exactly 20% down. When we tested different scenarios with recent clients, the break-even point typically occurred when buyers could save the additional down payment within 18 months without sacrificing other financial goals.

Frequently Asked Questions

Can I switch from high-ratio to conventional mortgage at renewal?

Yes, if your home value has increased enough that you now owe less than 80% of its current value, you can switch to conventional at renewal. I've seen many Coquitlam clients do this after a few years of payments plus appreciation. Your CMHC premiums stop, saving you money going forward. CMHC

Do credit unions in BC require CMHC insurance for high-ratio mortgages?

Yes, BC credit unions must use mortgage insurance for loans over 80% loan-to-value, just like banks. I work with several local credit unions in the Tri-Cities, and they use CMHC, Sagen, or Canada Guaranty. The difference is credit unions often have more flexible qualification criteria than big banks. BCFSA

What happens to my CMHC insurance if I sell my BC home early?

Your CMHC insurance stays with the mortgage, not the property. When you sell, the mortgage gets paid off and the insurance ends. You can't transfer it to a new home - you'd need new insurance if your next purchase is also high-ratio. I always explain this to my Port Moody clients considering moving up. CMHC

Conclusion

The choice between high-ratio and conventional mortgages really comes down to your down payment situation and long-term goals. If you're putting down less than 20%, you'll automatically be in high-ratio territory with mortgage insurance premiums, but that's not necessarily a bad thing - it gets you into homeownership sooner in markets like Coquitlam where prices keep climbing. I've seen many clients successfully use high-ratio mortgages to get established in neighbourhoods like Burke Mountain or Port Moody, then refinance later when they've built up equity. The key is understanding the true cost of mortgage insurance and factoring that into your monthly budget planning.
