Top Dollar: How High Can You Go?

Shanna Davis • November 20, 2018

Affordability is a major concern for today’s aspiring first-time homebuyers. In hot real estate markets like the Greater Toronto and Greater Vancouver regions, however, the desire for affordability can be challenged by the competitive fervour caused by escalating prices and bidding wars. As anyone who has researched homeownership in these markets knows, it’s easy to feel the pressure to bid higher than you’d like.

Resist the urge. It’s important to go house hunting with a firm price range in mind. If something is outside of your budget, it’s not affordable – period. A successful home purchase isn’t about beating out 20 other offers; it’s about sealing the deal on a home you can afford, with money left over each month after your mortgage is paid, to cover your other expenses, savings and a little bit of fun, too.

It’s a tall order, but there  is  a formula to help you find that sweet spot.

Find Your Right Price

Lenders and mortgage insurers look at two debt service ratios when qualifying you for a mortgage (and mortgage insurance, which you will need if you make a down payment of less than 20 per cent the cost of the home).

  • Gross debt service (GDS)
    The carrying costs of your home, such as mortgage payments, taxes, heating, etc., relative to your income.
  • Total debt service (TDS)
    Home carrying costs (mortgage payments, taxes, heating, etc.) plus your debt payments (credit cards, student loans, car loans, etc.), again relative to your income.

The highest allowable GDS ratio is 39 per cent, and the highest allowable TDS ratio is 44 per cent.

Want a shortcut to determining affordability? Use Genworth.ca’s “What Can I Afford?” online mortgage calculator. Input your income, current monthly debt payments and other details for an instant result that shows how much mortgage you can comfortably afford. (Note: For the interest rate, be sure to input the Bank of Canada’s conventional five-year mortgage rate, as that is what lenders use when determining GDS and TDS.)

Down Payment Strategies

Once you know how much mortgage you can manage, limit your house hunt to homes that keep you in that price range. That way, you won’t panic or find yourself in financial trouble if interest rates go up in the future.

You can buy “more house” for the same total mortgage if you have a larger down payment. Saving aggressively is one way to do that. Pair that with other strategies, such as the following:

  • Borrowing money from your RRSP under the government’s Home Buyers’ Plan.
  • Asking family for help via gifts or loans. (Don’t be embarrassed: 23 per cent of respondents in the 2017 Genworth Canada First-Time Homeownership Study say they’d do it!)
  • Taking on a side gig or second job.
  • Gulp! Moving back home with your parents so you can save on rent.

Location, Location, Location

The other way to end up with a smaller mortgage is to buy a less pricey house. Fixer-uppers help, but the most dramatic payoff may come from expanding your search to a wider radius.

Consider buying in a nearby city or suburb that you can commute to work from. Or blaze new ground by moving farther afield in search of a new home and new adventures – with the spare cash to enjoy them both!

When arranging mortgage financing, your mortgage lender will register your mortgage in one of two ways. Either with a standard charge mortgage or a collateral charge mortgage. Let’s look at the differences between the two. Standard charge mortgage This is your good old-fashioned mortgage. A standard charge mortgage is the mortgage you most likely think about when you consider mortgage financing. Here, the amount you borrow from the lender is the amount that is registered against the title to protect the lender if you default on your mortgage. When your mortgage term is up, you can either renew your existing mortgage or, if it makes more financial sense, you can switch your mortgage to another lender. As long as you aren’t changing any of the fine print, the new lender will usually cover the cost of the switch. A standard charge mortgage has set terms and is non-advanceable. This means that if you need to borrow more money, you'll need to reapply and requalify for a new mortgage. So there will be costs associated with breaking your existing mortgage and costs to register a new one. Collateral charge mortgage A collateral charge mortgage is a mortgage that can have multiple parts, usually with a re-advanceable component. It can include many different financing options like a personal loan or line of credit. Your mortgage is registered against the title in a way that should you need to borrow more money down the line; you can do so fairly easily. A home equity line of credit is a good example of a collateral charge mortgage. Unlike a standard charge mortgage, here, your lender will register a higher amount than what you actually borrow. This could be for the property's full value, or some lenders will go up to 125% of your property's value. In the future, if the value of your property appreciates, with a collateral charge mortgage, you don't have to rewrite your existing mortgage to borrow more money (assuming you qualify). This will save you from any costs associated with breaking your existing mortgage and registering a new one. However, if you’re looking to switch your mortgage to another lender at the end of your term, you might be forced to discharge your mortgage and incur legal fees. Also, by registering your mortgage with a collateral charge, you potentially limit your ability to secure a second mortgage. So what’s a better option for you? Well, there are benefits and drawbacks to both. Finding the best option for you really depends on your financial situation and what you believe gives you the most flexibility. This is probably a question better handled in a conversation rather than in an article. With that said, undoubtedly, the best option is to work with an independent mortgage professional. It’s our job to understand the intricacies of mortgage financing, listen to and assess your needs, and recommend the best mortgage to meet your needs. As we work with many lenders, we can provide you with options. Don’t get stuck dealing with a single institution that may only offer you a collateral charge mortgage when what you need is a standard charge mortgage. So if you’d like to have a conversation about mortgage financing, please get in touch. It would be a pleasure to work with you and answer any questions you might have.

What Is a Second Mortgage, Really? (It’s Not What Most People Think) If you’ve heard the term “second mortgage” and assumed it refers to the next mortgage you take out after your first one ends, you’re not alone. It’s a common misconception—but the reality is a bit different. A second mortgage isn’t about the order of mortgages over time. It’s actually about the number of loans secured against a single property —at the same time. So, What Exactly Is a Second Mortgage? When you first buy a home, your mortgage is registered on the property in first position . This simply means your lender has the primary legal claim to your property if you ever sell it or default. A second mortgage is another loan that’s added on top of your existing mortgage. It’s registered in second position , meaning the lender only gets paid out after the first mortgage is settled. If you sell your home, any proceeds go toward paying off the first mortgage first, then the second one, and any remaining equity is yours. It’s important to note: You still keep your original mortgage and keep making payments on it —the second mortgage is an entirely separate agreement layered on top. Why Would Anyone Take Out a Second Mortgage? There are a few good reasons homeowners choose this route: You want to tap into your home equity without refinancing your existing mortgage. Your current mortgage has great terms (like a low interest rate), and breaking it would trigger hefty penalties. You need access to funds quickly , and a second mortgage is faster and more flexible than refinancing. One common use? Debt consolidation . If you’re juggling high-interest credit card or personal loan debt, a second mortgage can help reduce your overall interest costs and improve monthly cash flow. Is a Second Mortgage Right for You? A second mortgage can be a smart solution in the right situation—but it’s not always the best move. It depends on your current mortgage terms, your equity, and your financial goals. If you’re curious about how a second mortgage could work for your situation—or if you’re considering your options to improve cash flow or access equity—let’s talk. I’d be happy to walk you through it and help you explore the right path forward. Reach out anytime—we’ll figure it out together.
