Mistakes to Avoid When Buying a Home in Ottawa
The most common mistakes when buying a home in Ottawa are financial and procedural: skipping a mortgage pre-approval, forgetting closing costs, changing finances before closing, waiving conditions without understanding the risk, and skipping the home inspection or condo status certificate. Each is avoidable with preparation and a knowledgeable local agent.
Buying a home is one of the largest purchases most people make, and a single misstep can cost thousands. This guide covers the mistakes that catch Ottawa buyers most often and how to sidestep them.
Jason Polonski is a full-time Ottawa and Kanata REALTOR® with Right at Home Realty whose trades and finance background helps buyers avoid costly errors. Buyers can reach him by phone at (613) 601-9333 or by email at polonskiottawa@gmail.com.
Not Setting a Realistic Budget
The first mistake is shopping without a clear budget based on comfortable monthly affordability, not just the maximum a lender approves. A budget should account for the mortgage, property tax, insurance, utilities and maintenance.
Overextending leaves no cushion for repairs or rate changes. Setting a firm ceiling early keeps the search focused and prevents falling for homes that quietly strain the finances. The Canada Mortgage and Housing Corporation offers homebuying and budgeting resources that help set that ceiling.
Skipping Mortgage Pre-Approval
Shopping without a pre-approval is a frequent and costly mistake. A mortgage pre-approval confirms the true budget, locks in a rate and signals to sellers that the buyer is serious.
Without one, a buyer risks falling for a home they cannot finance or losing out in competition. The Financial Consumer Agency of Canada explains what a lender verifies during pre-approval.
Forgetting Closing Costs and Land Transfer Tax
Many buyers budget for the down payment and forget the rest. Closing costs typically add another 1.5% to 4% of the price, covering land transfer tax, legal fees, title insurance and the inspection.
In Ontario, buyers pay provincial land transfer tax, though first-time buyers can recover up to $4,000 through the Ontario land transfer tax refund. Jason’s guide on how much is needed for a down payment breaks down the full upfront cost.
Changing Finances Before Closing
One of the most damaging mistakes happens after an offer is accepted. Financing a car, opening new credit, changing jobs or making large deposits can all cause a lender to withdraw a mortgage approval before closing.
A pre-approval is not final until the lender issues the mortgage commitment and the deal closes. Buyers should keep their finances stable from offer to closing, and the Financial Consumer Agency of Canada’s credit guidance is a useful reference.
Sell Your Ottawa Home for Just 1% Listing Commission
Why pay 2.5% listing commission to sell your home when you don't have to? Jason Polonski lists Ottawa homes for a simple 1% listing commission. Full MLS® and REALTOR.ca exposure, professional photography, powerful online marketing, expert pricing, and a skilled negotiator fighting for every dollar of your sale price. Top-tier service — you just keep thousands more when your home sells. Smart sellers are already making the switch. Your home deserves the best, and your wallet deserves a break.
Skipping the Home Inspection
Waiving the inspection to save money or win a bid is a serious risk. A professional home inspection reveals structural, electrical, plumbing and roofing issues that are invisible during a showing.
Jason’s trades background helps buyers interpret the report and price repairs, and choosing an inspector accredited by the Ontario Association of Home Inspectors adds confidence. Buyers who want to make a firm offer should still complete a pre-offer inspection rather than skip it entirely.
Waiving Conditions Without Understanding the Risk
In competitive situations, buyers sometimes drop financing, inspection or legal conditions to strengthen an offer. Doing so without preparation exposes them to losing a deposit or facing an unexpected repair.
The safe approach is to complete the due diligence before the offer, not to skip it. Jason’s guide to buying a house with no conditions explains how to compete without taking on reckless risk.
Get Cash Back When You Buy a Home in Ottawa
Can you get cash back when buying a home in Ottawa? Yes. Jason Polonski, a Chairman's Club REALTOR® serving Ottawa and Kanata, shares part of his commission with buyers — up to $3,000 cash back at closing.* You still get full-service, award-winning representation: expert pricing, sharp negotiation, and hands-on guidance from first showing to keys in hand. No cut corners and no rebate-only shortcuts — just real money back in your pocket when you buy your Ottawa or Kanata home.
Skipping the Condo Status Certificate
For condo buyers, the biggest mistake is not reviewing the status certificate. This document reveals the corporation’s finances, reserve fund, rules and any legal issues, and skipping it can mean inheriting a special assessment or a rental ban.
A lawyer should review the status certificate before conditions are waived. It is one of the most affordable safeguards in a condo purchase.
Overpaying in a Bidding War
Emotion drives the costliest mistakes. In a multiple-offer situation, it is easy to bid beyond a home’s value or beyond a comfortable budget just to win.
Staying grounded in recent comparable sales prevents overpaying; using Ottawa Real Estate Board data as a benchmark and remembering that the highest offer does not always win helps. Jason’s guides to negotiating a better deal and finding a bargain-priced home keep buyers disciplined.
Ignoring the Neighbourhood and Commute
Focusing on the house and overlooking its location is a common regret. Commute, transit, schools, amenities and safety all shape daily life and future resale.
Visiting an area at different times of day gives a truer sense of it, and the Ottawa Neighbourhood Study maps amenities and services across the city. A great house in the wrong location rarely feels like a good decision later.
Forgetting Resale Value
Even a long-term home is eventually sold, so resale should factor into the decision from the start. Location, layout, condition and neighbourhood trajectory all affect how easily a home will sell later.
Hard-to-fix drawbacks, such as a poor location or an awkward layout, can limit the future buyer pool. Thinking a few years ahead protects the investment.
Overlooking Radon and Rural Systems
An Ottawa-specific mistake is failing to test for radon. Ottawa sits in an area with elevated radon potential, and Health Canada recommends that every home be tested, since radon is invisible and odourless.
Rural buyers face additional checks. A rural property needs separate well water and septic inspections, and skipping them can lead to expensive surprises after closing.
Not Working with a Buyer’s Agent
Trying to navigate a purchase alone is a mistake, especially since a buyer’s agent is usually free to the buyer. An experienced agent provides market insight, listing access, negotiation skill and protection from costly errors.
Understanding what a REALTOR® does for a buyer makes the value clear. The right agent turns a stressful purchase into a confident one.
Not Reading the Agreement of Purchase and Sale
The agreement of purchase and sale is legally binding once accepted, yet some buyers sign without fully understanding it. Price, deposit, conditions, closing date and included items are all set out in this document.
A REALTOR® explains each clause and a real estate lawyer reviews the contract before closing. Jason’s guide to the buyer representation agreement also explains how a buyer’s own agreement protects their interests.
Underestimating Ongoing Maintenance Costs
A home’s costs do not stop at the mortgage. Buyers who overlook ongoing maintenance, repairs and eventual replacements, from the roof to the furnace, can find ownership more expensive than expected.
A common guideline is to set aside roughly one percent of the home’s value each year for maintenance. Older homes and rural properties often need more, so budgeting realistically prevents financial strain.
