Have You Considered Going Tankless?

Luisa Hough • September 21, 2015

If you are looking for ways to be more responsible with energy costs around your home (and save a little money in the process), considering a tankless water heater is probably already on your radar. But is it really worth it? There are certainly a lot of factors that will go into your decision about equipping your house with one of these units! Here are a couple things you should consider!

What are you trying to accomplish by going tankless?

The most common reasons people choose a tankless water heater are:

1. Not to have to wait for hot water.

2. Not to have the hot water run out.

3. To save space by not having a huge tank.

4. More environmentally responsible.

5. To save money long term compared to a hot water tank.

Before rushing into buying a tankless water heater, you should ask yourself?

1. How long am I currently waiting for hot water?

2. Am I currently running out of hot water on a regular basis?

3. Is saving space a concern for me?

4. How efficient is my current water heater? Obviously going tankless will be more efficient, but just how much more? There is a good chance your current unit is performing at a level that isn’t horrible.

5. How much money will I save yearly with a tankless heater compared to a hot water tank? Make sure you understand how long it will take to recover the added upfront costs of going tankless through the long term money savings on your energy bill! If it’s going to take you 75 years to recoup your money, is it really worth it?

Just as each house is different and has unique needs, so is each person and family. There is certainly no cut and dry, right or wrong answer when it comes to Tank vs Tankless. The best you can do is evaluate your needs and make an informed decision!

Water heating can account for 25 per cent of the energy bill for many Canadian homes – especially those with large families that use lots of hot water. Hot water usage can be reduced by installing low-flow shower heads, faucet aerators, insulating pipes, and water efficient appliances.

You may also be able to reduce your water heating bill by installing an “on-demand” or “instantaneous” water heater. These compact water heaters use high inputs of gas or electricity to instantly heat water as it is needed. As high-efficiency tankless water heaters don’t have to keep large volumes of water heated 24 hours a day, studies have shown that they can reduce energy consumption for water heating by 40 per cent.

Tankless water heaters can be hung on a wall and require little floor space making them attractive for smaller homes. But they need to be properly located, sized and installed to meet your household’s needs. For instance, gas-fired instantaneous water tanks may need different venting arrangements and perhaps larger gas pipes to deliver higher gas flows to the heater.

Keep in mind that the energy savings from an instantaneous water heater can literally go down the drain if their “endless” hot water capabilities just mean longer showers by household members.

Whatever system you choose, it’s always a good idea to know the costs and potential savings so you can make an informed decision. Ask a qualified contractor to assess your hot water needs and recommend a water heating system that will meet them as efficiently and cost-effectively as possible.

Breaking Down the Real Costs of Homeownership

By Luisa & Candice Mortgages • April 15, 2026
Don’t Forget About Closing Costs When planning to buy a home, most people focus on saving for the down payment. But the truth is, that’s only part of the equation. To actually finalize the purchase, you’ll also need to budget for closing costs —the out-of-pocket expenses that come up before you get the keys. Closing costs can add up quickly, which is why they should be part of your pre-approval conversation right from the start. Lenders will even require proof that you’ve got enough funds set aside. For example, if you’re getting an insured (high-ratio) mortgage, you’ll need at least 1.5% of the purchase price available in addition to your down payment. That means a 10% down payment actually requires 11.5% of the purchase price in cash to make everything work. Let’s break down some of the most common expenses you should prepare for: 1. Home Inspection & Appraisal Inspection : Paid by you, this gives peace of mind that the property is in good shape and doesn’t have hidden problems. Appraisal : Required by the lender to confirm value. Sometimes this is covered by mortgage insurance, sometimes by you. 2. Legal Fees A lawyer or notary is required to handle the title transfer and make sure the mortgage is properly registered. Legal fees are often one of the larger closing costs—unless you’re also responsible for property transfer tax. 3. Taxes Many provinces charge a property or land transfer tax based on the home’s purchase price. These fees can range from hundreds to thousands of dollars, so you’ll want to factor them in early. 4. Insurance Property insurance is mandatory—lenders won’t release funds without proof that the home is insured on closing day. Optional coverage like mortgage life, disability, or critical illness insurance may also be worth considering depending on your financial plan. 5. Moving Costs Whether you’re renting a truck, hiring movers, or bribing friends with pizza and gas money, moving comes with expenses. Cross-country moves especially can be surprisingly pricey. 6. Utilities & Deposits Setting up new services (electricity, water, internet) can involve connection fees or deposits, particularly if you don’t already have a payment history with the utility provider. Plan Ahead, Stress Less This list covers the big-ticket items, but every purchase is unique. That’s why it pays to have an accurate estimate of your personal closing costs before you make an offer. If you’d like help planning ahead—or want a breakdown tailored to your situation—let’s connect. I’d be happy to walk you through the numbers and make sure you’re fully prepared.

How Your Loans and Spending Habits Are Quietly Shaping Your Credit Score

Your credit score is one of the most important numbers in your financial life — especially when it comes to getting a mortgage. But for most Canadians, how that number actually gets calculated remains a bit of a mystery.

What Online Mortgage Calculators Can—and Can’t—Tell You

By Luisa & Candice Mortgages • April 8, 2026
What Online Mortgage Calculators Can—and Can’t—Tell You Online mortgage calculators are everywhere—and on the surface, they seem like a no-brainer. You plug in some numbers, and out pops what you can “afford.” Simple, right? Not quite. While the math itself is correct, the story behind those numbers is often misleading. Mortgage qualification isn’t just about numbers—it’s about context, risk, and lender policy. And that’s where calculators fall short. The Numbers Are Accurate—but the Picture Isn’t An online calculator can show you what a payment might look like at a given interest rate, or how making extra payments could reduce your amortization. That’s useful information! But when it comes to mortgage qualification , calculators don’t account for the many variables that lenders consider, such as: Your credit history and score Employment type (salary, self-employed, contract) Outstanding debts and monthly obligations Assets, savings, and down payment source The property type and location you’re buying Lenders evaluate all these factors through their internal risk models. That means two people entering the exact same numbers into a calculator could receive very different results when they actually apply for a mortgage. Why Online Calculators Can Mislead You When you see a “How much can I afford?” or “Mortgage Qualification” calculator online, it’s easy to treat the result as fact. But these tools don’t know your financial story—they only crunch the data you enter. A calculator can’t predict how a lender views your risk, how new mortgage rules apply to your file, or how things like spousal support, car loans, or variable income will impact approval. In short: calculators estimate payments, not qualification . Use Calculators the Right Way Don’t get us wrong—online calculators still have value. Use them to explore different “what-if” scenarios: How do payments change with different down payment amounts? How would a rate increase affect affordability? What if you added $100 a month to your payments? These tools are great for helping you understand your comfort zone. Just remember: they’re a starting point, not a green light. The Real First Step: Get a Pre-Approval If you’re serious about buying a home, skip the guesswork and get a mortgage pre-approval . It’s quick, free, and gives you real-world clarity on what you can afford. A pre-approval looks at your full financial picture—income, credit, debts, assets—and provides a framework for your purchase price, payment range, and rate options. It’s the only way to get a reliable answer to the question, “What can I really afford?” Final Thoughts Online calculators are convenient, but they can’t replace expert advice. Think of them as a starting point, not a solution. A professional mortgage broker can interpret the numbers, navigate lender policies, and tailor your financing strategy to your actual situation. If you’d like help understanding your true buying power—or want to get pre-approved with confidence— reach out anytime . I’d be happy to walk you through your options and help you make sense of the numbers.
