Buy vs rent guide
Maintenance and repair costs in a buy vs rent comparison
Of all the costs that separate owning from renting, upkeep is the hardest to predict and the easiest to underestimate. In a buy vs rent comparison it can decide the winner, so it helps to see how sensitive the answer is before you pick a number.
Why maintenance is different from other costs
A mortgage payment is fixed for the term and property tax arrives on a schedule. Maintenance does neither. Roofs, furnaces, windows, appliances, driveways and plumbing wear out on their own timelines, and a single repair can cost more than several months of normal housing costs.
Renters generally do not pay for these repairs, because the landlord is responsible for the building’s structure and systems. That makes maintenance one of the clearest cost differences between the two options, and it is a cost that often does not show up on a listing or a mortgage quote.
Smoothing the lumps with a percentage of value
The engine treats maintenance as a percentage of home value per year and adds it to the owner’s monthly cost. The default is 1%, which is $6,000 a year, or $500 a month, on a $600,000 home. Because the base is the home’s value, the dollar amount rises as the home appreciates.
That percentage is a planning convention, not a measured average. A newer home with warranties may cost less in the early years; an older home with original systems may cost more. A larger or more complex property will generally cost more than a small one in absolute terms.
How much the percentage matters
Suppose a $600,000 home in Alberta with 20% down, a 4.5% rate, rent of $2,300 a month and a ten-year hold, with the other calculator defaults. Only the maintenance percentage changes. These are illustrations, not predictions.
| Maintenance (% of value per year) | Ten-year total | First-month owner cost | Break-even | Buyer minus renter at year 10 |
|---|---|---|---|---|
| 0.5% | $35,194 | $3,507 | 3.9 years | $87,432 |
| 1.0% | $70,388 | $3,757 | 5.7 years | $41,686 |
| 1.5% | $105,583 | $4,007 | none within ten years | -$4,060 |
| 2.0% | $140,777 | $4,257 | none within ten years | -$49,807 |
Reading the table
The swing is large. Moving from 0.5% to 2% turns a result of buying ahead by $87,432 into renting ahead by $49,807, with no change to the rate, price growth or rent. Maintenance alone can flip the answer.
Time horizon matters too. At 1.5% buying is slightly behind after ten years but ahead by about $9,106 after twenty. At 2% it is still behind by about $133,564 after twenty years. The longer you stay, the more the compounding of equity helps, but only if upkeep is reasonable relative to the home’s value.
Special repairs and major projects
A percentage works for ordinary wear. A large, planned project is a different thing. The engine has a separate yearly line for special assessments and major-repair reserves, which is explained in condo fees and special assessments. For a house, you can use the same line to spread the cost of a known project such as a roof replacement.
An allowance of $3,000 a year for such costs, on top of the 1% maintenance in the example, brings the ten-year result from buying ahead by $41,686 to renting ahead by about $1,288. That is a small number set against the home’s value, but it is enough to move the answer to the other side of zero.
Condos, new builds and older homes
Condominium owners usually pay a monthly fee that covers common-area upkeep, so the maintenance percentage for their own unit is much lower. Compare condo vs house and check the building’s reserve fund before assuming the fee covers everything.
New builds often have lower early repair costs but may bring other costs, such as finishing a yard. Older homes may have lower purchase prices but higher upkeep. See new build vs resale.
What to do before you buy
A pre-purchase inspection will not tell you what will break, but it will tell you what is old. Ask for the age of the major systems and budget accordingly. Keep a repair fund separate from your emergency fund.
Then run the numbers with a low, medium and high percentage in the true cost of owning tool. If the answer flips within a plausible range, treat the decision as close and look at non-financial factors too. For the full list of ownership costs, see hidden costs of owning.
Questions people ask
How much should I budget for home maintenance?
There is no single right number. A percentage of home value per year is a common way to plan, and the right figure depends on the age and condition of the home. Try 0.5%, 1% and 2% and see how much the result changes.
Do renters pay for repairs?
Generally the landlord is responsible for the building’s structure and systems, but tenants may be responsible for damage they cause. Check your lease and your province’s tenancy rules.
Is a home warranty or inspection enough?
They help, but they do not remove the cost. Warranties have limits and expire, and an inspection is a snapshot of the home’s current condition.
Is maintenance included in my condo fee?
The fee usually covers common areas and shared systems, not the inside of your unit. Ask for the budget and the reserve fund information to see what is covered.
