Buying a House?

Finance6 min read

When wrestling with the question of whether to buy or rent my primary residence in Canada, this has served as a living document frequently updated with latest resources and thoughts. Keeping them public and open to discussion has sharpened my thinking and kept me same as I've hashed out different ideas and approaches with others.

For my 2019 rough notes application of the Principles for Navigating Big Debt Crises to the Canadian Real Estate market, see The State of Canadian Real Estate in 2019. It probably deserves fresh guidance given the changing winds from COVID-19 in 2020 but alas, I have not yet.


  • Housing is a highly subsidized and incentivized investment (RRSP withdrawal program, no capital gains on primary residence, various homebuyer and renovations tax credits...)
  • In wilder markets in Canadian cities, RE price index has been increasing at >5% for the past 20 years. Recent years (2020) has seen year over year price index increase by 8-10% in Toronto and Kitchener-Waterloo. (Index link below). Locking in prices before they continue to go up could make sense.
  • Interest rates are extremely low and will likely be for the next 5-10 years. Rates haven't been this low since the 1920s making this an optimal time for a mortgage.
  • Cities like Kitchener-Waterloo outside of Toronto haven't been exposed to the same extent to the frenzied RE run up that GTA and Vancouver have faced meaning ownership prices could be closer to rent/buy breakeven price (see The 5% Rule in calculators below). For example, a $600,000 house in Kitchener, by the 5% rule, would make sense if a comparable house can't be found long term for rent of $2500 or less. If your registered investment accounts are maxed out, then expected opportunity cost of your ownership sunk cost if you had invested in stocks is lower (since stock gains in non-registered accounts are taxable) so 4% can end up being more accurate. Rent equivalent for $600,000 house with the 4% rule is $2500. The bulk of houses on Kijiji are renting in KW for \$2000-2800, meaning that the rent/buy difference that is much more clear cut in the condo market or in Toronto housing market, is a bit more of a tossup in KW right now.
  • They ain’t making more land
  • You eventually own where you live which could ideally drop your monthly costs to utilities, maintenance, and property tax
  • Forced savings vehicle (won’t ever not make a mortgage payment, might skip savings some months if not disciplined)


  • Responsible for maintenance
  • Almost certainly higher cash cost for just the mortgage let alone taxes, renovations, utilities on a per month basis
  • Locked into a single location (every move drastically drops ROI of owning)
  • Opportunity cost of the reduced cash flow per month ($300/month put into investments starting at age 25 grows to $1 million by 65, \$600/month starting at age 35) especially at young age
  • Opportunity cost of kingdom and charity projects that are funded out of cash flows and from maintaining lower living standards
  • Accustoms children to higher living standards than in an apartment or rented house
  • Reduces patience with annoyances of rental properties when as an owner there is power in your hands to continually fix annoyances
  • Home equity is not liquid unless a loan is taken out against it
  • Retirement can’t be funded from the equity value increase in a house unless loan taken out against the value
  • Owning encourages upgrades and renovations to improve it (it’ll pay off and add value to the home when we sell)
  • Owning can cause unrelated lifestyle increases: living far away => more commuting / second car; spend more on renovations per year ($5-10k vs $0 renting)
  • Reduced job mobility (moving is much harder)
  • Reduced willingness to travel and leave house vacant for long periods of time
  • Reduced cash flow / increased % spent on housing leads to higher income requirement and tighter margin of error if either person loses employment or wants to take leave for a period of time
  • 30+ year bull Canadian RE housing market, willing to bet it will continue another 40 to cover our lifetime (I’m not sure...)
  • Near peak for short term and long term debt cycle (Ray Dalio), thus deleveraging of some sort is coming, likely leading to reduction or pause in growth in house prices as most over leveraged sell houses and others decide not to buy or upgrade because of overextended debt levels.

    • Take house price * 5% (total unrecoverable annual cost: 1% property tax + 1% maintenance + 3% cost of interest) / 12 to find the monthly break even of home ownership compared to rent at equivalent location.
    • Video notes that if individual will be investing rent / own difference in a taxable investment account (ie. RRSP and TFSA room are maxed) then the rule may be closer to 4% because of the reduced difference between investing in stocks and home ownership from the taxation of investment gains.

Common Questions and Answers

  • What if you rent part of your primary residence, still eligible for primary residence capital gains exemption on sale? You will encounter a "deemed disposition that normally arises on a partial change in use of property", aka you loss exemption status on the % of the house that you're now renting. CRA
  • Isn't buying real estate the best way to maximize leverage? Couldn't you then use that leverage for stock investing or other purposes?
    • Leverage, yes! Usable for non-real estate, no. After research into HELOCs, readvanceable mortgages, and all sorts of other strategies, it's become clear that it's nearly impossible to use the leverage available in a mortgage outside of the specific real estate property that the mortgage is for.
    • How do you maximize leverage?
      • At best, you can get a 5% down mortgage and then once 20+% has been paid down in principle (usually past year 10 with a 25 year amortization), you can get a HELOC to keep pulling equity out and maintaining leverage long term. Some HELOCs have a loan limit set on setup based on assessment of the house.
      • At the other end of the spectrum, you could pay for the house in cash and then withdraw up to 80% in a HELOC. The terms are important because some have payment plans similar to a mortgage so you lack the flexibility (that you get with a Line of Credit) that you need to put the money long term in stocks for example. Additionally the interest rate on HELOCs are often 1-2% higher than the rates you get with a mortgage, so it's difficult to see how the house purchase, which locks up 20% minimum in down payment / minimum HELOC equity, can provide any additional leverage than simply using the full 100% (used to initially pay the house).
      • Other HELOCs, sometimes packaged as readvanceable mortgages (Scotiabank/BMO offers them), will automatically increase in credit room based on the principal parts of the continued regular mortgage payments. For example, if $1000 of your $2200 mortgage payment is going towards principle and you already have over 20% home equity, your HELOC will expand in room each month by \$1000. In this case, you could maintain high leverage on your house by withdrawing from HELOC the principle part of your payment and investing in stocks for example. Some readvanceable mortgages have lower limits than normal HELOCs only allowing borrowing up to 65% (vs HELOC normal 80%) of house value.
    • Can you refinance every year to maximize ongoing leverage?
      • Nope, refinancing essentially results in a brand new mortgage and thus new paperwork and closing costs. You can get a Home Equity Line of Credit (HELOC) but only of an amount surplus to 20% of the mortgage value. For example, for a $500k mortgage, you can't get a HELOC until $100k of principle has been paid down, and then your HELOC is only in the best case the amount above that. So if you've paid down $150k of principle, you can get a $50k HELOC to flexibly withdraw equity out of the house at slightly above prime rates, and less than an unsecured line of credit.
