Hi. I'm Jake. I believe you can build a wealthy life through frugal living and index investing.

Elders preach home ownership as the best investment. Friends are buying homes, and explosive housing growth ignites a Fear of Missing Out (FOMO), especially for young buyers in Canada.

To add to these pressures, we are told that renting is throwing money away. This is true, but homeowners also throw money away. It’s just not as obvious.

Examples include property tax, home maintenance, and mortgage interest.

Then there is the weird hidden cost of the money tied up in the house (home equity). Money tied up in home equity is money that cannot be invested to achieve higher long-term returns in the stock market. That is a hidden cost, labeled as an “Opportunity Cost” in economics.

The real question when considering renting vs. buying is “what option results in throwing the least amount of money away?”

I’ll show that between 4% and 6% of a home’s value is “thrown away” every year for homeowners. You can use this calculator to provide a more detailed outline of your unique home ownership costs.

I hope you walk away from this post with at least one thought that helps you make this giant financial decision with care and confidence.

Ownership: A Huge Decision

The average house price in my area (Ontario) is over $890,000. That’s over 12 years of after-tax income for someone making $100,000 per year. I find this to be a tad depressing. 

I believe we should all think deeply and do our research before we dedicate over 10 years of salary towards a purchase. In addition, we should understand the specific risks we take on as homeowners and renters.

The True Cost of Home Ownership

There are four categories of homeownership costs that do not go towards the mortgage principle. Therefore, this money does not stay in your pocket or contribute to the growth of wealth. 

Three of these costs are easy to see, but one is a hidden, implicit cost.

Overall, I’ll show that the total cost of home ownership is between 4% and 6% of the home value. This is the amount that does not go towards wealth accumulation. 

Credit for this approach belongs to Ben Felix at PWL Capital. He covers the topic well in the embedded video. You can also check out the PWL Capital white paper titled “A Case for Renting“. 

Let’s look at the four main costs of home ownership.  

1. Property Tax

Property tax averages 1% of home value per year. The exact property tax rate will depend on your municipality and their appraised value of the homes.

You can plug your exact property tax rates into the rent vs buy calculator.

2. Home Maintenance

Homes require maintenance. The structure of the home is a depreciating asset. It goes down in value over time. It’s the land that appreciates in value. 

To upkeep the value of the structure, you must:

  • Pay to fix things that break. I call this “corrective” maintenance; 
  • Keep the house up to date with the time. Prevent obsolescence. 

Roofs wear until they leak, foundations crack, furnaces fail and pipes can burst. 

The rule of thumb is that homeowners set aside a minimum of 1% of the house value per year on corrective maintenance costs. You can read this post to learn more about budgeting for home maintenance costs.

So you can expect $5,000 in-home maintenance costs per year for a $500,000 home. 

These unplanned maintenance costs often come as large lump sum expenses that average out to be roughly 1% of the home value per year.

That means you also need a bigger emergency fund, which is money that you cannot use to invest. Instead, its value erodes to inflation until a large expense comes due. 

Finally, you need to update the house to keep up with the times to retain its value.  Otherwise, things become obsolete and the structure will not be worth as much to others.

Preventing obsolescence can look like a new kitchen, new flooring, or updating the exterior. You can easily add another 1% of the home value to obsolescence maintenance, for a total home maintenance cost of 2% of the home value annually. 

3. Cost of Debt (Mortgage Interest)

Mortgage interest, the cost of debt, is another unrecoverable cost. You don’t get this back. 

I quick look at shows interest rates at 3%.

I’ll assume a 2% mortgage rate in our low-rate stimulated environment. You pay a 2% free to “rent out” the mortgage. Assuming a 20% down payment, you’ll have to loan out 80% of the home value, and you’ll pay a 2% fee on this amount. 

4. Cost of Money Tied Up in Your House (Cost of Home Equity)

Money put down on a house is money that you can’t use to purchase assets with higher returns. 

Global stocks have historically beat real estate appreciation over the past 122 years, returning 5.3% annually versus a 1.3% for residential real estate (source). 

You miss the “opportunity” for higher returns by putting money into a house.  I estimate the opportunity cost of equity at 4%. 

Opportunity cost is a central concept in economics 101 and personal finance. It can help you form a strong mindset around all spending decisions. 

All returns above are inflation-adjusted. You can access the global stock market at low cost with index funds. Canadians can use low-cost one-fund ETFs such as XEQT or VEQT

You can check out the globally diversified index fund portfolios for Canadians on Canadian Couch Potato or the Rational Reminder blogs.

Adding Them Up

Home maintenance and property tax add up to a 2% cost. Next, we have to take the weighted average of the 2% cost of mortgage debt and the 4% cost on the home equity amount. This brings the total unrecoverable cost of ownership between 4% and 6% of the home value.

This can be confusing, especially the split between home equity and mortgage interest. You can assume 3% for the combined cost of the mortgage and equity opportunity cost.  This leaves you with the 5% rule of thumb. The example below should clear things up.

Or you can use the calculator to view the breakdown and achieve higher accuracy. 

Rent vs Buy Calculator


The calculator performs the comparison more accurately: 

  • Fine-tune by entering mortgage rates, home equity, and property tax rates.
  • Input house price and rental price for comparison.

A Rent vs Buy Example

Now that we have the four costs, let’s crunch the numbers for an $890,000 home with a 20% downpayment. This is the average home price in Ontario at the time of writing.

The 20% down payment of $178,000, leaves you with $712,000 in mortgage debt. The 2% mortgage interest on this amount costs you $14,240 per year. 

While the $178,000 tied up in the house could have instead been used to gain a 5.3% inflation adjusted return in global stocks, instead of the 1.3% inflation adjusted return of real estate. You therefore incur an opportunity cost of 4% on your $178,000 or $7,120.

Rent vs. Buy: Other Financial Considerations

Financial Factors Favoring Home Ownership

  • Capital gains income from the appreciation of your primary residence is tax-free.
  • The RRSP home buyers’ plan allows first-time home-buyers to withdraw up to $35k tax-free from their RRSP to put down on a house. It must be paid back within 15 years. 
  • A higher allocation to bonds will reduce returns and decrease the opportunity cost of home equity. A large fraction of bonds in a portfolio will bring you closer to a 4% rule. 

Financial Factors Favouring Renting

  • I didn’t factor in realtor fees, legal fees and land transfer tax. These costs approach 5% of the home value when you sell. Renting eliminates this cost.
  • Frequent moves increase the risk associated with house price volatility. Housing risk is enhanced by mortgage leverage. Losing borrowed money is worse than losing your own money. 
  • Interest rate risk. You can gauge the sensitivity of mortgage payments to interest rate changes using this mortgage calculator.  Interest rate risk is a double whammy. When rates rise, the mortgage payments increase on variable-rate mortgages and you can see a decline in home prices. 
  • Bidding wars make it stressful to buy. In these wars, you may not be able to get a house inspection. When you buy “as is” you risk buying a disaster.

Rent vs. Buy: Behavioral Considerations

Behavioral Factors Favoring Ownership

  • A mortgage forces you to save by paying the mortgage. Renters must implement an alternate  forced savings system to invest instead of splurging. 
  • Owners have more freedom to landscape, renovate and do interior design. 
  • Renters need a tough stomach to handle the short-term ups and downs of investing in equities (stocks). 
  • You won’t get evicted.
  • Owning your home fulfills human need for security.

Behavioral Factors Favoring Renting

  • You don’t need to deal with the costs, stress and time of home maintenance.
  • You can have a smaller emergency fund. 
  • Shelter costs are easy to quantify, simplifying financial planning.
  • You have more flexibility to move, offering a form of freedom.


  • There exists cultural pressure (and a group of real estate agents) advocating ownership. This imposes a confirmation bias in favor of ownership.
  • People often state their home is their best investment. That’s because a home is the only investment many people make.
  • The opportunity cost of ownership is hidden and non-intuitive, imposing a bias towards ownership. It’s easy to ignore what you can’t see. 
  • Seeing home prices skyrocket elicits FOMO. It’s logical to expect future appreciation similar to the long-term historical average of 1.3%, after inflation.


Both renters and homeowners “throw money away”. The amount thrown away is just more difficult to measure for homeowners. 

The question is “which option results in throwing the least amount of money away?” That option will maximize your long-term wealth. 

It makes more financial sense to rent if the annual rent is less than 4%-6% of the house price. You can plug your specific data in to the rent vs buy calculator, or you can keep it simple and assume a 5% rule. 

You are unique, and the best option for you will be unique. Perhaps owning your home is extremely important. Or maybe you move alot.
