If you're thinking about buying a home in Ontario, you’ve probably heard the word “mortgage” a lot. But what does it actually mean? Don’t worry, you’re not alone. Let’s break it down in simple terms.

What Is a Mortgage?

A mortgage is a loan you get to help you buy a home. The bank or lender gives you money, and you agree to pay it back. You set a time duration with your lender, usually every month.

Think of it like borrowing a big amount now and slowly paying it back, with interest, while living in your new place.

Is a Mortgage a Loan?

Yes, a mortgage is a loan, but it's a special kind of loan just for real estate. What makes it different?

  • It’s usually a large amount of money
  • It’s paid back over a long time (like 5, 10, 20, 25 years)
  • If you can’t pay at the set duration, the lender can take the home back

So, yep, it’s a loan, but it’s tied to your house.

What Is the Structure of a Mortgage?

A mortgage is built like a puzzle with four main pieces:

  1. Loan Amount (Principal) – This is the money you borrow to buy the home.
  2. Interest – The extra money you pay the lender for borrowing.
  3. Taxes – In Canada, you might pay property taxes as part of your monthly payment.
  4. Insurance – This helps protect your home or the lender, depending on the plan.

Together, these are often called PITI: Principal, Interest, Taxes, and Insurance.

What Is a Mortgage in Principle?

A mortgage in principle (also called a pre-approval in Canada) is a letter from a lender saying they’re likely to give you a mortgage if your details check out.

It helps you:

  • Know your budget before you shop
  • Show sellers you’re serious
  • Move faster when you find the right home

In short, it’s a “yes, likely”,  not a final approval, but close.


What Are the 4 Parts of a Mortgage?

Let’s repeat it clearly — the four parts of a mortgage are:

  1. Principal – The money you borrow
  2. Interest – The cost of borrowing
  3. Taxes – Property taxes (can be part of your payment)
  4. Insurance – Home or mortgage insurance

Understanding these helps you know where your money goes each month.
