…The Mortgage Matchmaker: Finding the Right Fit for Your Payments and Your Future

Let’s face it—mortgages aren’t exactly cocktail-party conversation. But if you’re like most homeowners, you’ve probably asked yourself more than once: “Am I really getting the best deal on my mortgage?” That’s the kind of question that can keep you up at night—or at least make you wince every time a payment comes out of your account.

That’s why I built the Mortgage Payment Scenarios Calculator. It’s not just about crunching numbers—it’s about putting you in the driver’s seat. You can run scenarios, compare your current mortgage to a new one, or even pit different lenders against each other. The best part? It shows you not only how your monthly payments stack up, but also how much interest you’ll save (or pay) over the term and the entire life of your mortgage.

Here’s what we’ll cover today:

Why Comparing Mortgages Matters

Here’s the deal: not all mortgages are created equal. Two lenders might offer the same rate on paper, but when you factor in term length, amortization, prepayment privileges, and renewal options, the difference in what you pay—or save—can be massive.

Most people stick with their bank out of habit, never realizing they could shave years off their mortgage or save thousands in interest. Comparing isn’t just smart—it’s money in your pocket.

How the Calculator Works (And What It Shows You)

This isn’t your average “plug in your mortgage amount and rate” tool. My calculator lets you:

  • Run Scenarios: Change rates, terms, amortizations, or payment frequencies to see how your payments shift.
  • Compare Current vs. New Mortgage: Find out if breaking your existing mortgage and switching saves you money—even after penalties.
  • Stack Lenders Side by Side: At renewal or refinance, compare different lender offerings to see who’s really giving you the better deal.
  • See Interest Savings Clearly: Break down the difference in total interest over the next term and the entire life of your mortgage.

It’s like having a financial crystal ball—you see not just what happens today, but how today’s choice ripples into tomorrow.

A Realtor’s Secret Weapon at Renewal or Refinance

For realtors, this tool is gold when working with clients who are upsizing, downsizing, or investing. You can use it to show them how freeing up equity or changing their mortgage structure impacts cash flow.

Imagine sitting with a couple who want to buy a second property. Instead of guessing, you run the numbers and demonstrate how refinancing their current mortgage at a sharper rate saves interest and unlocks funds for a down payment. That kind of clarity turns “maybe someday” into “let’s do it now.”

A Story: Tom and Maria’s Mortgage Makeover

Tom and Maria had a $500,000 mortgage with their bank at 5.5%. Their renewal letter arrived with a “preferred offer” at 5.2%. They figured it was decent—until they tried my calculator.

They entered their numbers and compared the bank’s offer to another lender’s 4.9% with better prepayment options. The results were eye-opening:

  • Monthly payment difference: about $150 lower with the new lender
  • Term interest savings: almost $9,000
  • Lifetime interest savings: over $40,000

Armed with that data, Tom and Maria switched lenders. They now pay less each month and know they saved enough money to cover their kids’ future university tuition.

Putting the Numbers Into Practice

Here’s how you can use the calculator in real life:

  • Homeowners at Renewal: Compare your bank’s “take it or leave it” offer against other lenders.
  • First-time Buyers: Test different down payment and amortization scenarios before committing.
  • Realtors: Use it in consultations to show buyers how financing choices impact affordability.
  • Investors: Run multiple scenarios to see how changing terms affects long-term profitability.
  • Families Considering Refinance: See how restructuring debt into a mortgage impacts monthly payments and overall interest.

It’s like test-driving a car—you wouldn’t buy it without knowing how it handles. Why would you lock into a mortgage without knowing the full picture?

Allen’s Final Thoughts

Mortgages aren’t just about rates—they’re about strategy. My Mortgage Payment Scenario Calculator pulls back the curtain and shows you exactly how different choices affect your payments, your interest costs, and your financial future.

As your mortgage agent, I go one step further. I’ll help you interpret those results, negotiate with lenders, and design a mortgage strategy that fits your life—not the other way around. Whether you’re renewing, refinancing, or buying for the first time, I’ll help you cut through the noise and focus on what really matters: saving money, building equity, and keeping your financial plan on track.

Because at the end of the day, it’s not about just getting a mortgage—it’s about getting the right mortgage for you.

Maintenance Reserves

Maintenance Reserves: “The Secret Safety Net”

You’ve probably heard the term “maintenance reserve” tossed around in commercial lending conversations and wondered if it’s just another way lenders make life complicated. But the truth is, maintenance reserves aren’t red tape—they’re your built-in safety net. They protect your property’s value, your cash flow, and yes, your lender’s investment too.

On Commission

Lenders and Being on Commission

If you’re earning your keep on commission — whether you’re slinging homes, closing car deals, or working your tail off in any other commission-heavy gig — you already know that explaining your income isn’t always simple. Some months you’re flush; others, not so much. But when it comes to getting a mortgage, how you get paid matters just as much as how much you get paid.

Limited Feature

The Truth About “Limited Feature Mortgages”

We’ve all seen them — those ultra-low mortgage rates advertised by the big banks or online lenders. They’re tempting, no doubt about it. Who doesn’t want to save a few bucks on interest? But here’s what you might not realize: those “basic,” “no-frills,” or “limited feature” mortgages come with some fine print that can cost you more down the road than you save upfront.

Open Banking

Get Ready for Open Banking

Open Banking: If you’ve ever felt like getting a mortgage meant running an obstacle course—chasing down pay stubs, digging through old bank statements, sending documents back and forth—you’re not alone. The process can feel outdated, clunky, and stressful. But here’s the good news: change is on the horizon. It’s called Open Banking, and it’s going to flip the script on how we verify income, assets, and financial history.

3rdPartyReports

Third Party Commercial Reports

Third Party Commercial Reports: If you’ve ever gone through a commercial mortgage process, you know it’s a different beast entirely compared to residential lending. It’s not just about income and credit—it’s about the property itself. The lender wants to know everything: how it’s built, how it performs, what risks it carries, and whether it’ll stand the test of time (and tenants).

CMHC BFS

Self-Employed? CMHC  Can Help You Buy a Home

If you’re self-employed in Canada, you already know the drill: your income looks fantastic before your accountant works their magic. After write-offs and deductions? Not so much. That’s why so many business-for-self (BFS) clients feel like they’re being punished when it comes time to apply for a mortgage. Even though you might have great cash flow, solid savings, and strong financial habits, your “net taxable income” doesn’t always tell the full story.

Appraisal Ownership

Who Owns the Appraisal?

If you’ve ever gone through a mortgage process and found yourself wondering, “Wait, I paid for that appraisal—why won’t the lender give me a copy?” you’re not alone. This is one of the most common sources of confusion and frustration among homebuyers, homeowners, and even some realtors. It feels like you should have a right to it, right? After all, you footed the bill!

Capitalizing NOI

Cap it Right: Reveal a Property’s True Worth

Capitalizing Net Operating Income (NOI): When you step into the world of commercial real estate, one phrase comes up over and over again — “What’s the cap rate?” or “Let’s capitalize the NOI.” And if you’ve ever wondered what those words really mean (beyond sounding like finance jargon from a spreadsheet), you’re not alone.

Mortgages Bay

Why Your Mortgage Rate is Tied to Bay Street

Ever wonder why mortgage rates seem to jump overnight even though you’ve done everything right? It can feel like the lender’s just making it up as they go along—but trust me, they’re not. What’s really happening behind the scenes is tied to something you might not think about: bonds and the capital markets.
