Can you Trust Online Mortgage Calculators?

Josh Perez • February 7, 2024

You’d think an online calculator is a pretty straightforward device, one that you should be able to place your confidence in, and for the most part, they are. Calculators calculate numbers. The numbers are reliable, but how you interpret those numbers, not so much, especially if the goal is mortgage qualification.


If you rely on the numbers from a “What can I afford” or “Mortgage Qualification” calculator without talking to an independent mortgage professional, you’re going to be misinformed.


Don’t be fooled. Even though an online mortgage calculator can help you calculate mortgage payments or help you assess how additional payments would impact your amortization, they’ll never be able to give you an exact picture of what you can afford and how a lender will consider your mortgage application.


While mortgage calculators are objective, mortgage lending isn’t. It’s 100% subjective. Lenders consider your financial situation, employment, credit history, assets, liabilities, the property you are looking to purchase. Then, they will compare that with whatever internal risk profile they are currently using to assess mortgage lending. Simply put, they don’t just look at the numbers.


An online calculator is a great tool to help you run different financial scenarios and help assess your comfort level with different payment schedules and mortgage amounts. However, if you rely on an online calculator for mortgage qualification purposes, you’ll be disappointed.


The first step in the mortgage qualification process is a preapproval. A preapproval will examine all the variables on your application, assess your financial situation, and provide you with a framework to buy a property based on your unique circumstance.


Securing a preapproval comes at no cost to you and without any obligation to buy. It’ll simply allow you the freedom to move ahead with confidence, knowing exactly where you stand. Something a calculator is unable to do.


Please connect anytime if you’d like to talk more about your financial situation and get a preapproval started. It would be a pleasure to work with you.

Deposit vs. Down Payment: Key Differences for Homebuyers

By Josh Perez • February 18, 2026
When you’re buying a home, two terms often cause confusion: deposit and down payment . While they’re related, they serve very different purposes in the homebuying process. Here’s what you need to know. What Is a Deposit? A deposit is the money you provide when you make an offer on a property. Think of it as a show of good faith that proves you’re serious about purchasing. How it works : Typically, you provide a certified cheque or bank draft that your real estate brokerage holds in trust. If your offer is accepted, the deposit remains in trust until the deal moves forward. If negotiations fall through, the deposit is refunded. Connection to your down payment : Once the sale is finalized, your deposit becomes part of your total down payment. Why it matters : The amount is negotiable, but a larger deposit can make your offer more attractive in a competitive market. Keep in mind, however, that if you back out after conditions are removed, you risk losing your deposit. What Is a Down Payment? Your down payment is the amount you contribute toward the purchase price of your home when securing a mortgage. Minimum requirement : In Canada, the minimum down payment is 5% of the home’s purchase price. Anything less than 20% requires mortgage default insurance. Sources : Down payments can come from your savings, the sale of another property, RRSP withdrawals (through the Home Buyers’ Plan), a gift from family, or even borrowed funds. Example: How They Work Together Imagine you’re buying a $400,000 home with a 10% down payment ($40,000). When you make your offer, you provide a $10,000 deposit . Once conditions are met, that deposit is transferred to your lawyer’s trust account. At closing, you add the remaining $30,000 to complete your full down payment. The lender provides the rest—$360,000—through your mortgage. The Bottom Line Your deposit shows commitment and secures your offer, while your down payment is what makes the mortgage possible. Together, they work hand in hand to get you into your new home. 📞 If you’d like clarity on deposits, down payments, or any other part of the mortgage process, let’s connect. I’d be happy to walk you through it step by step.
