How We Practiced Our Mortgage Payment Before Buying in PEI

If you’re saving for a home in PEI, you’ve probably stared at a mortgage calculator and wondered if the number on the screen is actually true. Numbers on a screen are easy. A bill that comes out of your account every single month, for months in a row, is a different kind of proof. That’s why my fiancée and I stopped guessing and started paying ourselves a pretend mortgage before we ever applied for a real one.

A down payment gets all the attention when people talk about buying a first home. But the bigger risk is signing up for a monthly payment you’ve never actually tested against your real life: groceries, gas, the odd night out, all of it. We wanted proof, not a guess, before we made the biggest purchase of our lives.

What a Practice Mortgage Payment Actually Is

The idea is simple. You figure out roughly what your future mortgage payment will be, then you start paying that amount to yourself every month, into a savings account, long before you actually buy. If you can comfortably make that payment for months in a row without touching your emergency fund, you have real proof you can afford the house. If you can’t, you’ve found that out with zero risk, instead of finding out after closing day.

How We Built Our $2,100 Number

We didn’t pull $2,100 out of thin air. We ran an online mortgage calculator using homes in our price range and preferred area, so the estimate was based on real listings we’d actually consider, not a random guess. That gave us a base monthly payment. Then we added a couple hundred dollars on top, to cover the costs a mortgage calculator doesn’t show you: home insurance, utilities, the general cost of owning instead of renting. $2,100 a month, on average, was the number we landed on and started paying ourselves.

What If You Already Pay Rent and Utilities?

Most people read $2,100 and think there’s no way. Fair. If you’re already paying rent, that money isn’t sitting around waiting to be saved.

But you’re not starting from zero. You’re already making a large housing payment every month, on time, without it breaking you. That’s the exact thing this test is trying to prove. The practice payment was never really about the full amount landing in savings. It’s about proving you can carry a payment that size reliably, without changing how you live.

So you don’t need to find $2,100. You need to find the gap.

Do the gap math

Add up what housing already costs you right now. Rent, power, heat, water, tenant insurance, all of it. Say that comes to $1,750. If your target mortgage payment is $2,100, the only untested part is $350.

That $350 is your practice payment. Move it into a separate account on the same day every month, treat it like a bill, and you’re running the same test we ran. You’re just getting credit for the part you’ve already proven.

If your rent and utilities already add up to more than your target payment, you’ve passed the affordability piece. The test becomes a savings test instead: every dollar you can move into that account is down payment, and the question changes from “can I afford this” to “how fast can I get there.”

Where this version of the test is weaker

Be honest with yourself about a few things:

  • Rent isn’t a perfect stand-in for a mortgage. Owning adds property tax, maintenance, and repairs that your landlord currently covers. That’s exactly why you pad the calculator number by a couple hundred dollars in the first place.
  • If utilities are included in your rent, you haven’t actually tested them. Estimate what they’d cost you and add that to the gap.
  • If you can’t cover the gap month after month, that isn’t a failure. That’s the whole reason you run this before you buy. It means the target price is too high, the timeline needs to be longer, or both. Finding that out now costs you nothing. Finding it out after closing day costs you a lot.

Running the Test From January to August

We started paying ourselves that $2,100 in January 2024. Every month, it left our account the same way a real mortgage payment would. By August 2024, seven months in, we knew two things for certain: we could actually afford the payment, and we’d built a meaningful chunk of our down payment at the same time, without ever having to “find” extra money for it.

Seven months is faster than most people need. The version of this strategy I walk clients through is built to run for up to two years, because most buyers are starting further out, with less of their down payment saved and a bigger gap between what they’re spending now and what a mortgage payment will actually cost. Your timeline depends entirely on where you’re starting from, not on hitting some magic number of months.

What the Test Actually Proved

A mortgage calculator can tell you what a lender thinks you can afford. It can’t tell you what your life feels like with that payment gone every month. Running the real payment through our real bank account for seven straight months told us the thing no calculator could: the number was livable, not just approvable.

It also meant we walked into our mortgage application already knowing we could carry the payment. No surprises, no adjustment period after we moved in. The “practice” period was the adjustment period, and we got to do it while we still had the safety net of renting.

Common Questions

What if your income changes partway through the test?

Adjust the number and keep going. The point isn’t to hit an exact figure every single month, it’s to build the habit and see how a payment that size fits against your real income over time.

Do you need a separate account for this?

It helps. Moving the money somewhere you don’t touch day to day makes it feel like a real bill instead of leftover cash sitting in your chequing account.

Does this work if you only have a few months before buying?

It’s less of a stress test the shorter it runs, but even a few months tells you more than a calculator alone. The longer version is what I recommend when someone has the runway for it.

Quick Recap

  • Estimate your future payment with a mortgage calculator based on homes you’d actually buy
  • Add a couple hundred dollars on top for insurance, utilities, and the real cost of owning
  • Pay that number to yourself every month, into an account you won’t touch
  • Let the length of the test match how far out you are, ours ran seven months, most people need longer
  • Use it to build your down payment and prove affordability at the same time
  • If you already pay rent and utilities, you only need to test the gap between that and your target payment
