Ottawa Row House at $575,000: Breaking Down the $3,847 Monthly Payment First-Time Buyers Actually Face
A 28-year-old federal analyst named Amir makes $87,000, has saved $35,000 in his FHSA and a registered account, and spent last Saturday touring four row houses in Riverside South. All were listed between $550,000 and $595,000. He walked out of the last one, three bedrooms, 1,420 square feet, listed at $575,000, thinking he could afford it because the mortgage was "only" about $2,800 a month. Then his realtor sent him the full breakdown. The actual number was $3,847.
Here's where the other $1,047 goes, and why it matters more than the mortgage payment.
The Mortgage Payment Isn't the Floor
Amir's lender approved him for $546,250 at 4.75% fixed over 25 years (he's putting $28,750 down, which is 5% on the first $500,000 and 10% on the remaining $75,000). Principal and interest: $3,098 per month. That's the number most buyers anchor on because it's the only one the bank talks about during pre-approval.
CMHC insurance is mandatory on any down payment under 20%. On a $546,250 mortgage, the premium is 4% of the loan amount: $21,850. Most buyers roll this into the mortgage, which bumps the actual financed amount to $568,100. Recalculate at 4.75%: $3,222 per month. Already $124 higher than the clean number.
Then there's the PST on the insurance premium. Ontario charges 8% on CMHC premiums, which in Amir's case is $1,748. This cannot be rolled into the mortgage. It's due at closing, in cash, on top of the down payment. Buyers who budget only for the minimum down often get caught here.
The Monthly Non-Mortgage Costs
Property tax on a $575,000 assessed row house in Riverside South runs about $6,400 annually, or $533 per month. Ottawa's residential rate sits around 1.12% for 2026, slightly higher than the outer suburbs but lower than older core neighbourhoods where assessments haven't caught up to sale prices.
Common element fees for a Potl (Parcel of Tied Land) row house, which most of the newer builds in South Keys, Findlay Creek, and Barrhaven are, typically land between $220 and $280 per month. These cover road maintenance, snow removal, and sometimes landscaping. Freehold row houses don't carry this fee, but they command a $60,000 to $80,000 premium at the same square footage.
Home insurance for a $575,000 row house with replacement cost coverage and $2 million liability: roughly $140 to $165 per month, depending on the insurer and whether you bundle with auto.
Utilities are the variable most buyers underestimate. Heating a 1,420-square-foot row house through an Ottawa winter (gas furnace, programmable thermostat, decent insulation) runs $160 to $210 per month averaged over the year. Hydro is another $90 to $120. Water and sewer, if billed separately, add $60 to $75. Call it $330 all-in, conservatively.
The $3,847 figure assumes Amir heats cautiously, keeps the thermostat at 19°C most of the winter, and benefits from a newer build with above-code insulation. It also assumes he's not financing closing costs, that his common element fee stays at $220 (the lower end), and that his insurance quote holds. Realistically, month-to-month cash outflow will spike in January and February when heating peaks. The $3,847 is the annual average, not the winter reality.
The federal stress test requires Amir to qualify at 6.75% (his contract rate plus 2%). At that rate, the same mortgage would cost $3,898 monthly. He passes, but barely. His debt service ratio lands at 41%, which is legal but leaves almost no room for a car payment, let alone saving for the reserve fund assessment that's coming in year three when the development's road needs resurfacing.
The $575,000 row house isn't unaffordable for Amir. But it's a tighter fit than the asking price suggests, and the $2,800 number he walked out thinking about isn't close to the true cost of ownership. The math works if he's planning to stay five years minimum and can stomach the first winter's utility bills. If he's unsure, a $525,000 stacked townhouse with included heat drops the monthly outflow by $400 and opens room to actually save.

Wait, the opening said $3,847. What gives?
