The rent-versus-buy debate is one of personal finance’s most exhausting recurring fights. You know the one: everyone you know has an opinion, your parents are sure you’re wasting money on rent (or that you’re drowning in debt if you bought), and somewhere on Reddit there’s a 47-comment thread explaining why both sides are completely wrong.
As someone tracking every dollar toward a 2030 retirement while living in one of North America’s least affordable cities, I had to cut through the noise. Is my condo an investment? Is it an inflation hedge? Or am I just paying someone — either a bank or a landlord — to have a roof over my head? This post walks through the debate, the math, and a deceptively simple rule that can settle 80% of the argument in about ten seconds.
Why the Debate Is So Hard (and Why Most People Get It Wrong)
The fundamental mistake most people make is comparing a mortgage payment to a rent payment. That’s an apples-to-oranges comparison at best, and actively misleading at worst.
A mortgage payment includes principal (which is forced savings — you’re building equity), interest (the cost of leverage), property taxes, and sometimes insurance. Rent is 100% unrecoverable — you hand over money and walk away with zero equity. But that doesn’t automatically mean buying is better, because ownership has a stack of unrecoverable costs that renters don’t pay directly.
This is where the frameworks matter — because once you see the real costs, the answer often flips.
Three Ways to Frame the Question
Frame 1: The Kiyosaki View (“Your House Is a Liability”)
In Rich Dad Poor Dad, Robert Kiyosaki famously argued that your primary residence is a liability, not an asset, because it takes money out of your pocket every month without putting any back in. By his definition — an asset puts money in your pocket; a liability takes money out — your home fails the test. It generates no cash flow. It demands repairs, property taxes, insurance, and opportunity cost on the equity you could have deployed elsewhere.
Is he right? It depends on your definition. This view resonates with the FIRE community because it forces you to ask: what is this asset actually doing for me? If your house costs $3,000/month and generates nothing, it’s a lifestyle expense masquerading as an investment.
Frame 2: The JL Collins View (“Don’t Buy a House to Get Rich”)
In The Simple Path to Wealth, JL Collins — the godfather of index fund investing — is blunt: houses are not investments. They’re expensive indulgences. His advice is to buy the minimum home you actually need, not the maximum you can afford, because the stock market historically outperforms real estate over long horizons. He’s owned homes, but he’s never pretended they were his path to wealth.
Frame 3: The Ben Felix View (“Unrecoverable Costs”)
Ben Felix, a Canadian portfolio manager with millions of followers on YouTube, introduced what has become the gold standard framework for this debate: the 5% Rule. Instead of comparing mortgage payments to rent, you should compare total unrecoverable costs on both sides. He breaks down the annual cost of homeownership into three buckets that total roughly 5% of the home value:
- Property tax: ~1%
- Maintenance and repairs: ~1%
- Cost of capital / opportunity cost: ~3% (what your equity and interest costs you in foregone investment returns)
The genius of this framework is that it creates an imputed rent number — the effective cost of shelter you’d pay regardless of whether you rent or own. It’s apples to apples.
Enter the Rule of 240
Here’s where it gets stupid simple. Ben Felix’s 5% rule says: take the home value, multiply by 5%, divide by 12. That’s your breakeven monthly rent. But let’s do the algebra once and hard-code it:
Home value × 0.05 ÷ 12 = Home value ÷ 240
That’s it. The Rule of 240. Take the purchase price, divide by 240, and you get the monthly rent where owning and renting have roughly equivalent unrecoverable costs.
The Math, With Examples
| Scenario | Home Value | Rule of 240 (Monthly) | Verdict if Actual Rent Is… |
|---|---|---|---|
| Mid-size Canadian city | $500,000 | $2,083 | Rent < $2,083? Rent. Rent > $2,083? Buy. |
| Vancouver 1-bedroom condo | $583,000 | $2,429 | Rent < $2,429? Rent. Rent > $2,429? Buy. |
| Toronto townhome | $850,000 | $3,542 | Rent < $3,542? Rent. Rent > $3,542? Buy. |
| SF Bay Area house | $1,500,000 | $6,250 | Rent < $6,250? Rent. Rent > $6,250? Buy. |
My Condo, My Math
I own a 1-bedroom condo in Vancouver valued at roughly $583,000. Using the Rule of 240, my breakeven rent is about $2,429/month. Let’s put that in context: similar 1-bedrooms in my building and neighbourhood are renting for well above that. On pure unrecoverable-cost math, I’m probably on the owning side of the line.
But here’s the nuance: I’m planning to sell this place in late 2030 or early 2031 and use the equity to fund my retirement. So for me, the condo isn’t just shelter — it’s a concentrated, illiquid position I plan to liquidate to feed my VEQT portfolio. During the years I live in it, it functions as both a consumption good and an asset hedge against Vancouver rent inflation. Once I sell it and dump the proceeds into index funds, it becomes investment capital proper.
When Renting Wins
Renting is the better financial choice when one or more of these conditions are true:
- Your breakeven (price ÷ 240) is well above market rent. This happens in cities with very high price-to-rent ratios. If you can rent a comparable place for $1,500 but the 240-rule says $2,400, renting and investing the difference wins — and the discipline to actually invest that surplus matters. Ben Felix’s analysis of 12 Canadian cities from 2005 to 2024 found that a disciplined renter investing the difference in stocks built about 14% more wealth than the average homeowner over that period.[web:4]
- You’re planning to move within 3–5 years. Transaction costs (legal fees, land transfer tax, realtor commissions, moving costs) run 5–7% of the purchase price. That’s a massive hurdle to clear if you’re only holding for a few years.[web:11]
- You want flexibility over stability. If your plan involves slow travel, digital nomadism, or moving between cities, owning anchors you to one very expensive postcode. Renting lets you lease-sprint your way through coffee countries.
- You don’t invest the surplus. If you’d spend the difference between owning and renting on lifestyle instead of investing it in index funds, the renter’s mathematical edge evaporates.
When Buying Wins
- Market rent exceeds your breakeven number. This is often the case in expensive cities where ownership costs are locked in but rents have caught up or surpassed that level. In Vancouver and Toronto, owning has often been cheaper than renting a comparable place, especially if you have a reasonable down payment and a fixed-rate mortgage.
- You’re staying put for 7–10+ years. The longer you hold, the more the 5–7% transaction costs get amortized across years of shelter. After about five years, homeownership typically breaks even with renting; after ten, it usually wins.[web:14]
- The hedge value is high for you personally. If you have kids in schools, deep neighbourhood roots, or a career that rewards staying in one place, owning eliminates landlord risk, rent hikes, and the anxiety of not having a home to come back to. Nobody talks about “rent flexibility” when you’re 70 and your landlord wants to renovate or sell.
- You’re leveraged in a rising market. A 20% down payment means you’re controlling a $500K asset with $100K of your own money. If prices rise 5%, your equity went up 25%. That’s the double-edged sword of leverage.
The Secondary Test: Price-to-Rent Ratio
Wealthsimple offers a complementary quick check: divide the home price by annual rent for a comparable place. If the result is around 15 or below, buying likely wins. At 15–20, it’s the gray zone. Above 20–23, renting almost certainly wins. Another framework from the Financial Tortoise walks through a 5-step process combining the 5% rule, price-to-rent ratio, timeline assessment, hidden cost accounting, and lifestyle questions.
A Caveat on the 5% Rule (and the 240 Rule)
Ben Felix created the 5% rule when mortgage rates hovered around 3%. Today, with rates significantly higher, some argue the imputed cost should be closer to 7–8%, which would make owning look worse by comparison. The Financial Tortoise notes this caveat explicitly. If anything, in a higher-rate environment, the Rule of 240 may be slightly optimistic about buying — the real breakeven number might be closer to dividing by 150–170.
That said, having a fixed-rate mortgage insulates you from future rate hikes, while a renter faces annual rent increases with no floor. Both sides have their risks; the rule just gives you a clean starting point.
Bottom Line
Your primary residence is not an investment in the portfolio sense — it’s a consumption choice plus an inflation hedge on shelter. Whether buying or renting makes more financial sense depends on your specific city, your timeline, and whether you can compare apples to apples using unrecoverable costs instead of mortgage payments.
The Rule of 240 won’t give you a perfect answer, but it will give you a starting number in about five seconds. From there, layer in your timeline, your discipline as an investor, and your tolerance for being at someone else’s mercy when your lease comes up for renewal. Sometimes the right answer is the one that lets you sleep at night, not the one that maximizes IRR.
