What Is a Ratio Mortgage?

In the context of conventional and high ratio mortgages, the ratio mortgage refers to the relationship between the size of the mortgage loan and the amount of the down payment the investor is willing to place when purchasing a property. It is also known as the loan-to-value ratio.

The down payment is the first initial payment you will make towards purchasing your future home. The required amount can range from a minimum of 5% up to 20%, depending on the property’s purchase price. Though saving up a lump sum of money may not always be easy, as unexpected situations in life often happen, a down payment must be paid from the funds currently in your possession.

It is important to note that the size of your down payment will determine your mortgage ratio.

Weighing Various Mortgage Options

When starting on your journey to purchase the home of your dreams, you will inevitably have to learn about mortgages and the various types offered. This may be overwhelming when you are thrown different mortgage option terms such as fixed vs variable, open or closed, convertible, and now possibly high ratio vs conventional.

A ratio mortgage is the ratio between the down payment and the mortgage loan. Usually expressed as a percentage, a high ratio mortgage is when the mortgage loan is over 80% of the purchase price and a conventional mortgage is 80% or less.

In this article, we will cover what a ratio mortgage is, the differences between a high-ratio mortgage and a conventional mortgage, and how this ratio will affect your mortgage plan.

High Ratio Mortgage Vs. Conventional Mortgage

A high ratio mortgage is when you make a down payment of less than 20% of the purchase price of the property you wish to purchase. As the minimum down payment is 5%, it is then possible to have a mortgage loan of up to 95%.

On the other hand, a conventional mortgage is when a larger down payment has been made, and the loan amount is 80% or more.

High ratio mortgages may be more appealing to first-time home buyers looking to enter the housing market as the minimum down payment is only 5% of the purchase price, but there is more to ratio mortgages that you should consider.

Since high ratio mortgages allow buyers to borrow more than 80% of the principal loan, you will be required to purchase mortgage insurance from a regulated source, such as Canada Mortgage House Corporation (CMHC), for their mortgage loan insurance. Mortgage insurance is necessary to protect lenders against default mortgage payments, also known as mortgage default insurance.

Understanding Ratio Mortgages and the Loan-to-Value (LTV) Ratio

As 80% or more of a property purchase that usually costs hundreds of thousands to millions of dollars is a significant amount of money to loan, the lender will set a loan-to-value (LTV) ratio when reviewing your mortgage application. Think of this as a risk assessment done by the lender where the higher the LTV ratio, the higher the risk of default payments.

A loan-to-value (LTV) ratio is a percentage that expresses the amount of a mortgage loan compared to the purchase price of the property. This percentage is calculated by dividing the total mortgage amount by the appraised value of the property. This implies the LTV ratio will directly influence whether a mortgage loan requires mortgage insurance, the cost of the insurance, and if the mortgage is considered a high ratio or conventional ratio.

Understanding Ratio Mortgages

For example:

Two partners decided to buy a home together. After finding their dream home for $1,000,000, they decide to purchase it and split a down payment of $150,000. In this case, they would pay a down payment of 15%, and the LTV would be 85%, which would be considered a high-ratio mortgage.

A high ratio mortgage of 85% would require the partners to purchase mortgage insurance and make higher monthly payments than if they had made a larger down payment.

Ratio Mortgages Vs. Interest Rates

You might then wonder why a high ratio mortgage might equate to a larger monthly payment. The answer is in two words: interest rates. Though there are also various types of interest rates, generally, the higher the principal loan given by the lender, the higher the interest rate will be. The interest rate is always calculated based on the amount of money owed.

On the positive side, purchasing the required mortgage default insurance for high ratio mortgages typically results in being offered lower interest rates. This is due to the lenders’ assurance of receiving a payout in the event of a defaulted mortgage payment. Thus, it can be viewed as a lower risk.

Does the Ratio Mortgage Affect the Amortization Period?

How Does the Ratio Mortgage Affect the Amortization Period?

Another factor the ratio mortgage can affect is the mortgage’s amortization period. The amortization period is the set length of time over which the entire debt will be repaid, typically over a set period of time through regular payments.

A conventional mortgage can extend the amortization period up to 35 years, whereas a high ratio mortgage can limit the repayment period to only 25 years. In addition to the higher mortgage payments, interest rates, and mortgage insurance costs, a high ratio mortgage will require paying the total amount within a shorter timeframe.

However, effective as soon as August 1st, 2024 lenders will begin to offer 30 year amortization periods on high ratio mortgages to eligible first time homebuyers purchasing newly constructed homes. Newly constructed condominiums that have had an interim occupancy period will be included.

Key Insights

We have covered that although a high LTV ratio mortgage may let a first-time home buyer purchase a home quicker, they may be paying more, including the cost of mortgage insurance, over a shorter period of time. All this will depend on the amount of the initial down payment towards the purchase and your mortgage ratio.

It is always recommended that you thoroughly research and consider all the available options when budgeting your mortgage plan so that you can make confident, well-informed decisions about purchasing your dream home.

    Time vs. Timing: Why Trying to Outsmart the Market Usually Backfires

    ByStan S.

    Let’s be real. You’ve probably told yourself some version of this: “The market feels risky right now. I’ll wait until things settle.” “Rates are too high. I’ll jump in when they drop.” “Prices are up. I missed the window—maybe next year.” The problem? That window you’re waiting for—where everything is calm, cheap, and certain—doesn’t exist. It’s a mirage. And the longer you chase it, the further behind you fall. In investing, hesitation is often more dangerous than volatility. The Illusion of Perfect Timing Market timing sounds great in theory: buy low, sell high, make bank. But in real life? It rarely plays out that clean. Even the pros—with armies of analysts and AI tools—miss the mark. So what chance does the average investor have while scrolling headlines and watching rate announcements? Let’s put numbers on it. A Fidelity study showed that missing just the 10 best days in the market over 20 years can cut your returns in half. And those “best days”? They usually happen when things feel the worst—right after crashes, corrections, or full-blown panic. That’s the trap. Most people get scared, pull out, and miss the rebound. They think they’re avoiding risk, but what they’re really doing is locking in loss. Why Time in the Market Wins There’s a better way—and it doesn’t require a crystal ball. It just requires consistency. It’s called Dollar-Cost Averaging (DCA), and it’s as unsexy as it is effective. Here’s how it works: You invest a set amount of money on a regular schedule (weekly, bi-weekly, monthly). You buy more when prices are low, less when they’re high. Over time, this averages out your cost per unit and reduces the impact of short-term volatility. More importantly, it removes emotion from the process. No more second-guessing. No more reacting to headlines. Just steady, methodical action that compounds quietly in the background. And yes—it works in up markets, down markets, sideways markets. Because you’re not trying to beat the market. You’re just staying in it long enough to win. Behavioral Finance Backs This Up This isn’t just opinion—it’s behavioral science. Study after study shows that people who try to time the market underperform the market. Why? Because emotion hijacks logic. Fear during dips. FOMO during rallies. The brain treats financial loss like physical pain. So we react, even when we shouldn’t. That’s why automation and discipline are your best friends. Remove decision-making from the process, and you remove the biggest threat to your returns: yourself. The Real Cost of Waiting There’s a hidden danger in doing nothing. Every month you delay, your cash sits still while inflation moves forward. Your purchasing power erodes. And the opportunity cost quietly stacks up. Waiting for “the right time” to invest is like waiting for the perfect moment to have a kid, start a business, or buy your first property. It always feels like a big leap. But the longer you put it off, the harder it gets to catch up. Bottom Line You don’t need to guess right. You need to show up consistently. Forget timing the market. That’s a gambler’s game. Instead, play the long game. Pick a date, set your investment schedule, and stick to it—whether the market is booming, busting, or somewhere in between. Because the truth is this: The market rewards participation, not perfection.

    Gregor Robertson housing comment reflects a deeper truth, says urban planner

    ByStan S.

    Posted May 21, 2025 8:09 pm. Last Updated May 21, 2025 10:53 pm. When former Vancouver mayor Gregor Robertson made his comment on Canada’s housing market last week, there might have been more truth in it than many of his critics want to admit. “Finally, someone said it out loud, something we all know, but are not supposed to say,” said long-time Vancouver city councillor and urban planner, Gord Price in an interview with 1130NewsRadio. Not even 24 hours into his new role as Minister of Housing, Infrastructure and Communities, Robertson was clipped saying he does not think housing prices need to be lower . But Price is coming to Gregor Robertson’s defence and thinks critics should widen their lens. “I am not sure how much people really want government to be setting the price up or down.” Price said. “Even if they could, they really can not and you would not want them to.” Price explains that it is important to remember that the housing market moves with global trends. And, if government tries to push prices down too hard, they risk setting off a chain reaction that could destabilize the economy. “If you do not like inflation, you are sure not going to like deflation,” Price argued.

Decision to Rent or Buy Although buying a home may seem out of reach, most renters don’t realize how much money they’re actually spending each year on someone else’s mortgage and profit. Owning a home almost always comes out ahead because your monthly rental payments could have been helping you build equity in your own home instead! It also helps to factor in tax benefits, property appreciation, and other incentives when you buy. Let’s compare the numbers to give you a clear picture. If you are currently renting at $2,500 per month, plus about $130 in utilities, you’re paying $2,630 monthly or $31,560 a year. This money will only cover your cost of living and won’t do much else for you. It primarily goes toward paying off your landlord’s mortgage. Now let’s look at the monthly carrying costs of owning your own home. Let’s say you purchased a $500,000 home with a 20% down payment to avoid additional mortgage insurance fees and took on a fixed 30-year mortgage at 4% interest. Your monthly payments will need to include your mortgage payments, property taxes (1% of the property’s value annually), home insurance, and utilities.
