Comparative Market Analysis (CMA) in Ottawa
A comparative market analysis, or CMA, is a REALTOR®’s evidence-based estimate of a home’s value, built by comparing it to similar homes that have recently sold, are currently listed, or failed to sell in the same area. Unlike an online estimate, a CMA is prepared by a person who has looked at the actual comparable sales and adjusted for the specific home’s condition, features, and location — which is why it’s the standard tool for setting an accurate list price. This page explains exactly how one is built and how to read the result.
Building a reliable CMA takes more than pulling recent sales — it takes judgment about which comparables genuinely apply and how much each difference is worth. Jason Polonski has prepared comparative market analyses across Ottawa’s west end for 15+ years, drawing on a background in construction, finance, and the trades to interpret what the numbers actually mean for a specific home.

How a CMA actually works
A CMA starts by identifying “comps” — homes that closely match the subject property in size, age, style, lot, and location — and then adjusts the value up or down for meaningful differences between them. A finished basement, an updated kitchen, a premium lot, or an aging roof can each shift a comp’s price relative to the home being valued. The result isn’t a single guessed number; it’s a defensible price range grounded in what has actually happened in the market.
The three types of comparables
A thorough CMA draws on three categories of data, each telling a different part of the story.
| Comparable type | What it shows | Reliability |
|---|---|---|
| Recently sold homes | What buyers actually paid | Highest — the truest signal of value |
| Active listings | What current competition is asking | Medium — shows demand, not confirmed value |
| Expired or withdrawn listings | Where the market rejected a price | Useful for finding the ceiling |
Sold homes carry the most weight because they represent completed transactions, not hopes or asking prices. Active listings, visible on REALTOR.ca, show what a home is competing against right now, and expired listings reveal where pricing went wrong for other sellers — a useful warning sign.

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.
What goes into a professional CMA
Beyond the comps themselves, a proper CMA weighs several layers of detail: location and lot characteristics, size and layout, bedroom and bathroom count, the age and condition of major systems, upgrades and unique features, and current market timing — including how many days similar homes are taking to sell and how much inventory is competing for buyers. Local knowledge adds real value here: recognizing an updated electrical panel, a structurally sound addition, or a lot backing onto greenspace can shift a number meaningfully, which is where Jason’s trades background sharpens the analysis beyond what the raw data alone would suggest. The Appraisal Institute of Canada makes a similar point about professional valuation: trained judgment consistently outperforms data alone.

Why a CMA matters more in a city like Ottawa
Ottawa isn’t one market — it’s a collection of micro-markets, and a citywide average says very little about what a specific home is worth. Kanata, Stittsville, Barrhaven, Westboro, and the Glebe all move somewhat independently, and even within a single neighbourhood, a lot backing onto a park or proximity to a top-rated school can shift value noticeably. A home’s true worth lives at the street level, which is exactly what a CMA is built to isolate — a citywide number from the Ottawa Real Estate Board or Canadian Real Estate Association is a useful backdrop, but never a substitute for a comparison against homes on the same or a similar street.
CMA vs. appraisal vs. online estimate
These three tools answer different questions, and confusing them leads to mispricing. A CMA sets a competitive list or offer price and is prepared free by a REALTOR®. A formal appraisal, usually ordered by a lender, confirms value for financing and tends to be more conservative. An online estimate gives a quick, low-reliability ballpark that can’t see a home’s condition or the nuance of its specific street. The full breakdown of appraisals specifically is on how to prepare for a home appraisal, which covers that formal lender process in depth.
How a CMA guides pricing strategy
A CMA doesn’t produce one magic number — it produces a defensible range, and where a seller positions within that range is a strategic decision. Pricing too high causes a listing to sit and grow stale, training buyers to skip it; pricing too low leaves money on the table. Depending on conditions, that might mean pricing slightly below the comps to spark competing offers, or pricing at the top of the range when inventory is tight and demand is strong. Because market conditions shift, a CMA is a snapshot in time — in an active market, it’s worth refreshing before finalizing a list price, using current data from the Bank of Canada rate environment and local absorption trends as context.

When to request a CMA
A CMA is useful at several points beyond just listing day. It’s worth requesting months before a planned sale to identify which improvements are worth making before going to market — see how to increase your home value. Move-up buyers benefit from a CMA on both their current home and any target property, since both sides of the move affect the plan. A CMA is also valuable before submitting a competitive offer as a buyer, and when assessing home equity ahead of a renovation or refinance — the Financial Consumer Agency of Canada, Government of Ontario, and Canada Mortgage and Housing Corporation all offer background on how home equity and financing intersect.
Getting an accurate CMA for an Ottawa home

Comparative Market Analysis (CMA) FAQs
A CMA is a REALTOR®’s estimate of a home’s value, built by comparing it to similar homes that have recently sold, are currently listed, or have failed to sell nearby, then adjusting for differences in size, condition, and features. The result is a defensible price range grounded in real market data.
No. A CMA is prepared by a REALTOR® to set a competitive price, typically free of charge, while an appraisal is usually ordered by a lender to confirm value for financing and carries a fee. They often produce similar but not identical numbers, since they serve different purposes.
A well-prepared CMA built on genuinely comparable, recently sold homes is highly reliable for setting a list price. Accuracy depends heavily on the quality of the comparables chosen and the skill applied to the adjustments, which is why local experience matters.
Most REALTORS, including Jason Polonski, provide a comparative market analysis free of charge as part of their service to buyers and sellers.
In an active market, pricing conditions can shift within weeks, so a CMA used to set a list price should be current. Homeowners simply tracking their equity over time can refresh it less frequently, such as seasonally.
Buyers benefit from a CMA too. It helps ground an offer in real comparable sales rather than emotion or the list price alone, which is especially useful in a competitive, multiple-offer situation.
