Mortgage Financing Explained

Darrell McCollom • February 12, 2025

If you’re like most Canadians, chances are you don’t have enough money in the bank to buy a property outright. So, you need a mortgage. When you’re ready, it would be a pleasure to help you assess and secure the best mortgage available. But until then, here’s some information on what to consider when selecting the best mortgage to lower your overall cost of borrowing.


When getting a mortgage, the property you own is held as collateral and interest is charged on the money you’ve borrowed. Your mortgage will be paid back over a defined period of time, usually 25 years; this is called amortization. Your amortization is then broken into terms that outline the interest cost varying in length from 6 months to 10 years. From there, each mortgage will have a list of features that outline the terms of the mortgage.


When assessing the suitability of a mortgage, your number one goal should be to keep your cost of borrowing as low as possible. And contrary to conventional wisdom, this doesn’t always mean choosing the mortgage with the lowest rate. It means thinking through your financial and life situation and choosing the mortgage that best suits your needs.


Choosing a mortgage with a low rate is a part of lowering your borrowing costs, but it’s certainly not the only factor. There are many other factors to consider; here are a few of them:


  • How long do you anticipate living in the property? This will help you decide on an appropriate term.
  • Do you plan on moving for work, or do you need the flexibility to move in the future? This could help you decide if portability is important to you.
  • What does the prepayment penalty look like if you have to break your term? This is probably the biggest factor in lowering your overall cost of borrowing.
  • How is the lender’s interest rate differential calculated, what figures do they use? This is very tough to figure out on your own. Get help. 
  • What are the prepayment privileges? If you’d like to pay down your mortgage faster.
  • How is the mortgage registered on the title? This could impact your ability to switch to another lender upon renewal without incurring new legal costs, or it could mean increased flexibility down the line.
  • Should you consider a fixed rate, variable rate, HELOC, or a reverse mortgage? There are many different types of mortgages; each has its own pros and cons. 
  • What is the size of your downpayment? Coming up with more money down might lower (or eliminate) mortgage insurance premiums, saving you thousands of dollars.


So again, while the interest rate is important, it’s certainly not the only consideration when assessing the suitability of a mortgage. Obviously, the conversation is so much more than just the lowest rate. The best advice is to work with an independent mortgage professional who has your best interest in mind and knows exactly how to keep your cost of borrowing as low as possible.


You will often find that mortgages with the rock bottom, lowest rates, can have potential hidden costs built in to the mortgage terms that will cost you a lot of money down the road. Sure, a rate that is 0.10% lower could save you a few dollars a month in payments, but if the mortgage is restrictive, breaking the mortgage halfway through the term could cost you thousands or tens of thousands of dollars. Which obviously negates any interest saved in going with a lower rate.


It would be a pleasure to walk you through the fine print of mortgage financing to ensure you can secure the best mortgage with the lowest overall cost of borrowing, given your financial and life situation. Please connect anytime!

Porting Your Mortgage: What You Need to Know Before You Rely on It Porting a mortgage means transferring your existing interest rate, remaining term, and outstanding balance from your current home to a new one when you sell and buy again. While some lenders—especially big banks—make porting sound simple, the reality is that porting a mortgage is often complex and far from guaranteed . It’s not a magic solution, and it doesn’t mean you automatically get to keep your old mortgage on your new home. In many ways, porting a mortgage feels like applying for a brand-new one—often with more conditions . Here’s why. 1. You Still Have to Re-Qualify Even though you already have the mortgage, the lender will reassess you. If you: Changed jobs Moved to a new city Are on probation Switched industries or income types …the lender may decline the port. Your previous approval does not carry over automatically. 2. The New Property Must Be Approved The lender also reassesses the new property . Just because they accepted your previous home as collateral doesn’t mean they’ll approve the next one. Expect: A new appraisal A review of the property’s condition Scrutiny around marketability and value If the lender isn’t comfortable with the property, the port can fail. 3. Property Values Rarely Line Up Perfectly Most moves involve a price difference. Buying a more expensive home: You’ll likely need additional funds at a blended rate, which can increase your payment. Buying a less expensive home: You may face a penalty for reducing the mortgage balance. Either scenario can affect your costs. 4. You Still Need a Down Payment Porting doesn’t mean you “swap houses” without cash. You still need: A down payment on the new purchase Closing costs Funds available at the right time This often surprises buyers. 5. Penalties Usually Still Apply (At First) Most lenders: Charge the full mortgage penalty when you sell Refund it only after the port is successfully completed If you’re relying on sale proceeds for your down payment, this temporary penalty can create a cash-flow issue. 6. Timelines Rarely Line Up Perfectly Real estate markets don’t cooperate. You might: Sell quickly but struggle to buy Find a home quickly but wait months to sell Closing dates rarely align, which complicates porting even further. 7. Port Periods Vary by Lender This is where the fine print matters. Depending on the lender, the port window may be: Same day only 30 days 90 days Up to 6 months If the port window is short, both transactions must close within that timeframe—or the port fails. Longer port periods offer flexibility, but also carry the risk of selling first and not finding a replacement property in time. The Bottom Line Porting your mortgage can make sense—especially if you have a strong rate and are buying a similar-priced home. But it is not guaranteed , and it comes with conditions, risks, and timing challenges. Portability is a feature, not a promise. Before you rely on it, it’s important to review all your options , including whether staying with your lender actually makes financial sense. If you’re planning to sell and buy, I’d be happy to walk you through the process, explain your options clearly, and help you decide whether porting is the right move—or if another strategy makes more sense.
