Everything Home Buyers Need to Know About Mortgages

The mortgage you choose is not just a rate. It is a decision about how you want your life to work.

Buying a home brings a lot of mortgage advice. Someone got a great rate, a buddy knows a banker, and there is always someone who is certain they know what the Bank of Canada will do next. Some of that advice is helpful. Some are simply delivered with great confidence and a small amount of actual understanding.

The rate is important in terms of affordability, of course. But the mortgage with the smallest number in the ad is not automatically the best mortgage for you. The term, amortization, payment type, prepayment privileges, penalty calculation, lender rules and your own plans all matter. A low rate attached to a mortgage that costs thousands to break can become a very expensive bargain in certain circumstances. You really need to assess your risk profile and the “what if” scenarios that could happen in your life.

Here is an easy guide as short as we could make it to what Canadian lenders look for, how mortgage approvals actually happen, what the main products do, and the questions worth asking (that may not be simply offered) before you sign. This is general guidance information; every lender and every borrower’s circumstances can differ, big time.

What the lender is really deciding

A lender is asking themselves two basic questions: can you repay the mortgage, and is the property acceptable security for the loan?

That means looking at more than your salary. The lender will verify income, employment or business history, credit history, debt payments, down payment and its source (which is very important and often overlooked), savings left after closing, and the property itself. For a purchase, the lender may also review the appraisal, title, taxes, condo fees, insurance and any unusual features of the home.

A mortgage is not approved because someone likes you. A strong relationship can help get a file understood and handled well. It can’t make a car lease disappear from the calculations. Banks are friendly, but their computers are not known for being sentimental.

Are you getting ready to buy your first house or add to your growing portfolio? Either way, the resources below can help:

The traditional lender’s square box

Most homebuyers hope to qualify with what is known as a prime lender: typically a major bank, credit union or other mainstream institution offering its best conventional versus secondary market lending. These lenders generally want a file that fits their rules without too much if any creative interpretation.

The strongest applications will generally have:

Stable, documentable income
A solid record of paying bills on time
Manageable existing debt that fits the box
A down payment that can be very clearly traced to an acceptable source
Enough ready cash to cover closing costs and ideally leave a reserve
A property that meets the lender’s standards and supports the loan amount

This is the square box. A borrower with seasonal income, a recent job change, self employment income that looks smaller on tax returns than it feels in real life, bruised credit, high debt, or an unusual property may be a perfectly responsible person and still not fit neatly inside it. A round peg in a square hole.

That is when the shape of the file matters. Some lenders have more flexibility than others. Alternative or “B” lenders may consider a more complicated application, usually at a higher rate and with additional fees or conditions.

Private lending can be a short term solution in specific situations, but its cost and exit plan need to be understood before anyone gets too happy about an approval. Getting a mortgage is one thing. Being able to afford the mortgage is the part we should care about.

How much debt is too much?

Lenders commonly use two measures called GDS and TDS. They refer to these all the time. You don’t need to memorize the acronyms, but you should understand what they mean.

Gross Debt Service (GDS) compares your monthly housing costs with your gross household income. Housing costs generally include the mortgage payment calculated at the qualifying rate, property taxes, heating costs and, where applicable, part of the condo fee.

Total Debt Service (TDS) adds your other debt payments. That can include credit cards, car loans, leases, lines of credit, student loans and support obligations. Government and mortgage insurance guidelines use limits around 39% for GDS and 44% for TDS, though exceptions and lender rules can vary. Those are ceilings used in qualification, not a recommendation for what will feel comfortable in your actual monthly budget plan.

The stress test adds another hurdle. Banks generally qualify borrowers at the greater of the contract rate plus two percentage points or 5.25%. So if your actual mortgage rate were 4.5%, the lender would test whether the numbers work at 6.5%. You pay the contract rate, but you must qualify as though the rate were higher.

That is why a $700 monthly car payment can matter more than people think. It is not just $700 less in the bank each month; it can reduce the mortgage amount a lender is willing to approve. A car lease counts too. Credit card balances and lines of credit count. If paying off a balance would improve qualification, compare that benefit with the cash you would use and any effect on your closing funds. DO NOT suddenly close or borrow against accounts. Your mortgage file is not the place for financial improv.

What happens inside underwriting?

A pre-approval is great and we always recommend going through the process, but it is not a mortgage approval for a house you have not bought yet. It is an early assessment based on information available at the time. The property, appraisal, final documents and changes to your finances can still affect the outcome. But it really expedites matters which can help when timelines are tight in competition for a property and also a good exercise in understanding your affordability.

Once you have an accepted offer, the application goes through the lender’s review process. A mortgage specialist or broker assembles the file. An underwriter then checks whether the application meets policies and whether the property value supports the loan. Depending on the file and details, some of this review may be automated if it fits neatly in the box and some may be handled by a person.

The underwriter may verify the details of your financial situation and may want to dig deeper. They may also request an appraisal or other documents about the property.

An approval often comes with conditions. That is not necessarily bad. It means the lender will proceed once specified items are satisfied. “Approved, subject to…” is not the same as “go ahead and buy a boat before closing.” Until the lender has confirmed that all conditions are met and the lawyer has the funds, keep your finances steady. Avoid new loans, large unexplained deposits, job changes or major purchases. The lender can always take another look before funding.

Mortgage term and amortization are different things
These two terms are often mixed up, and they do very different things.

The term is how long the current mortgage contract and its rate apply. Most borrowers choose a term of five years or less. At the end of the term, you renew, refinance, pay off the balance or move to another lender, subject to the contract and qualification rules.

The amortization is the projected time it would take to repay the entire mortgage if the payment and rate assumptions continue. A 25 year amortization does not mean you are locked into the same mortgage for 25 years. It means your payments are calculated on a 25 year payoff schedule, while your contract for those payments may renew in five years.

A longer amortization lowers the required payment and can help with monthly cash flow. The trade off is that you repay principal more slowly and pay more interest over time if you carry the mortgage for the full 25. It is not free money; it is more breathing room purchased with a longer repayment runway.

For insured mortgages, 30 year amortizations are now available to first time homebuyers and to buyers of newly built homes. The home must meet program rules, and the insured purchase price or lending value must be below $1.5 million. Buyers putting 20% or more down may also find 30 year options with some conventional lenders.

A first-time buyer may want a 30 year amortization because the payment is lower while they are establishing careers, paying for childcare or rebuilding savings after a down payment. A buyer in mid career may prefer a 25 year schedule to reduce interest and build equity sooner, or may choose 30 years for flexibility and make extra payments when cash flow allows. Someone approaching retirement may focus on whether the mortgage will fit pension income, when it will be paid down, and what renewal payments could look like if earned income falls.

Age alone should not decide the mortgage. Income, plans, risk tolerance etc. matter more.

The main mortgage products

Fixed or variable rate

A fixed rate stays the same for the term. Your scheduled payment is predictable, which many people value more than winning a rate gamble. If you break a closed fixed mortgage early, the penalty can be substantial. Many lenders calculate it using the greater of three months’ interest or an interest-rate differential (IRD), but the details and formula vary by lender and mortgage product.

A variable rate can move when the lender’s prime rate changes. With an adjustable payment variable mortgage, the payment changes as rates move. With a variable mortgage that has a fixed payment, the payment can stay the same while more or less of it goes to interest; if rates rise enough, the payment may no longer cover all the interest so ask what happens at this trigger rate and whether your payment can change.

A variable mortgage may have a smaller penalty for breaking early in some products, often three months’ interest, but don’t assume all variable mortgages work alike. Get the actual payout rules in writing.

Open or closed

An open mortgage is where you can pay it off or make extra payments without a prepayment penalty. That flexibility usually but not always comes with a higher interest rate.

A closed mortgage typically has a lower rate, but limits how much extra you can pay without a penalty. Many closed products can have annual lump sums or increasing regular payments. The amounts differ. Read them before you need them.

Conventional or insured

If your down payment is under 20%, you will need mortgage insurance, subject to eligibility and purchase price rules. The insurance protects the lender if the borrower defaults; it is not life insurance for you. The premium is usually added to the mortgage, which means you pay interest on it too!!

With 20% or more down, the mortgage is generally conventional and does not require insurance. That does not automatically mean the lender will offer the same rate or the same amortization choices. The right comparison is the full cost and terms, not just the label.

Portable, assumable and combined products

A portable mortgage may let you transfer some or all of its balance and terms to a new property, subject to lender approval, timing and qualification. An assumable mortgage may allow a qualified buyer to take over the existing mortgage, but the lender has to approve the buyer and the contract must allow it.

Some lenders combine a mortgage with a home equity line of credit. That can be useful, but a revolving credit line can also make it easier to keep borrowing against your house. Flexibility is valuable when managed on purpose and it is less charming when it quietly becomes permanent debt.

The penalty question people forget to ask

A mortgage break penalty can arise if you sell, refinance, transfer lenders or pay off more than your privileges allow before the term ends. The amount depends on the mortgage contract. Fixed rate penalties can be hard to compare because lenders may use different posted rates and IRD calculations. A mortgage with a slightly higher rate but a fairer penalty can be the better choice for someone likely to move or refinance.

Ask the lender to calculate examples in dollars, not just tell you about the formula.

What if you sell after one year? After three?
What if you refinance?
What if rates fall?

Ask whether the mortgage is portable, how long you have to port it, and what happens if the new home costs more or less. Its fair game to make them work for you.

Bank, broker or both?

Going directly to your bank can be a good choice. Your bank already knows some of your financial history, and you may like having your accounts and mortgage in one place.

A mortgage broker can compare products from multiple lenders, including lenders you may not approach directly. That can be useful if your income or property is more complicated, or if you want more comparison. Brokers do not have access to every lender OR every product, and the best fit is not always the lowest rate. Ask about incentives and fees related to their representation of you.

The bank relationship may matter in a practical way, where it can help someone understand your history and keep communication smooth. It does not guarantee approval or a special rate, but occasionally can impact rates offered. A broker’s value comes from knowing lender policies, presenting the file clearly and comparing lots of options BUT it is not from possessing a secret trapdoor into the bank’s vault.

For a major purchase, it is reasonable to compare a bank offer with a broker’s recommendation. But compare apples to apples. A rate comparison without a contract comparison is like comparing two cars by looking only at the paint colour.

Investment properties and rental income

If you are buying a rental property, lenders may use some of the expected or existing rental income to help qualify you. How much they count depends on the property, whether you will live there, the number of units, and the method used to calculate rental income. CMHC, for example, publishes different approaches, including up to 100% of gross rent from the secondary suite in a two unit owner occupied property under its applicable rules. Other situations may use a percentage of gross rent or net rental income.

An important question is whether the unit is permitted and legal under local zoning, building and fire requirements. DO NOT assume every lender will count income from an unauthorized basement apartment just because someone has been paying rent there for years. Policies vary, and legal status can also matter to insurance.

Co-signers: a helpful hand with real consequences

A co-signer or joint borrower may help when the buyer’s income, credit history or debt ratios are not enough on their own. The lender may include the co-borrower’s income, but it will also assess their own debts and credit. The structure matters: a guarantor, co-signer and joint owner are not always the same thing, and lenders may need different arrangements.

Anyone who signs the mortgage may become legally responsible for repayment. If the primary borrower misses payments, the lender can pursue the other borrower. This is important! The mortgage may also reduce the co-signer’s own borrowing capacity because it is a debt obligation lenders can consider when that person later applies for a mortgage or loan. Getting someone approved today can complicate their own purchase tomorrow.

Before a parent or other family member agrees, ask the lender and lawyer exactly what they are signing, whether they must be on title, how they can be removed later, and what happens if the relationship or financial circumstances change. A family conversation is much cheaper before closing than after it.

The same caution applies when adult children are added to a parent’s property title. Being on title by itself does not automatically mean the child has taken on the mortgage debt. There is a way of doing this where they are basically a class B owner that only triggers in death. But if the child is also added as a borrower, co-signer or guarantor, lenders may count that mortgage obligation when the child applies for their own financing. Even title changes without a new borrowing obligation can raise legal, tax, estate and lender questions.

Do not add someone to the title casually as a shortcut. Get legal and mortgage advice first.

Questions to ask before you choose a mortgage

The lowest advertised rate is easy to find. The details that can cost you money are usually a little farther down the page. Ask your lender or broker:

Is this a pre-approval, a rate hold, or an approval subject to conditions?
What income and debts did you use in the qualification calculation?
What documents or conditions are still outstanding?
What is the stress-test rate and maximum mortgage amount?
What is the payment at the actual contract rate, and what would it be at renewal if rates were higher?
What are the exact annual lump-sum and payment-increase privileges?
How is the penalty calculated if I sell, refinance or transfer the mortgage?
Can I port the mortgage?
Are there lender, appraisal, legal, broker or discharge fees?
If there is rental income, what percentage will you use, and what proof or approvals do you require?
If a family member helps, are they a joint borrower, guarantor, co-signer or owner, and how does that affect their own borrowing?
What happens if my closing date changes or the appraisal comes in below the purchase price?

Ask for the answers in writing. A good mortgage person should welcome informed questions.

The real goal

A mortgage should help you buy the home you want without making the rest of your life financially miserable. That means knowing what you can qualify for, what payment feels comfortable, how long you expect to stay, what could change, and what it costs to change your mind.

A lender decides how much it is willing to lend. You decide how much debt fits the life you want to live. Those numbers are allowed to be different and many times are.

The best mortgage is not always the one with the lowest rate, the biggest approval or the longest amortization. It is the one whose payment, flexibility and risks make sense for you after the excitement of getting the keys has worn off and the first property tax bill arrives.
