The Number You Got Online Isn’t Your Home’s Value. Here’s Why.

Online home valuation tools estimate your home’s worth using public sales records and broad neighborhood averages — not its actual condition, upgrades, or truly comparable sales — which is why the number they give is usually inaccurate, and often more so here in Manitoba than in bigger markets.

At some point before almost every listing appointment, a seller has already looked up their home online. They’ve found a number — from a valuation tool on an agent’s website, a real estate portal, or some variation of an automated estimate — and that number has started to feel like a fact.

It isn’t. Here’s what that number is actually based on, what it’s missing, and why the gap between an online estimate and what your home will actually sell for can be significant — particularly in this market.

What Online Valuation Tools Are Actually Using

Automated home valuation tools work from data. The question is: what data, and how much of it?

In many markets, these tools pull from publicly available sold listings — homes that have recently sold nearby, which they use to estimate what yours might be worth by comparison. That’s already an imprecise exercise, because algorithms can’t assess condition, renovations, or the difference between a home that faces a park and one that backs onto a highway.

An asking price is an opinion. A sold price is a market decision. 

What the Algorithm Can’t See

Even in markets where sold data is available, automated valuations miss things that matter. 

Condition is invisible to an algorithm. A home that has been well-maintained for 30 years and a home that has been neglected for 10 will show up as identical in a database if they’re the same square footage and year built. The algorithm doesn’t know about the new roof, the updated kitchen, or the basement that flooded twice.

Location within a neighbourhood is invisible too. Two homes on the same street can have meaningfully different values based on lot size, backing, traffic exposure, or proximity to amenities. An automated tool works from general area data — it doesn’t walk the street.

Buyer demand is invisible. What buyers are actively competing for right now in your price range isn’t something an algorithm can factor in. A home that would have taken 30 days to sell last spring might move in a weekend this spring, or vice versa. That timing affects value in ways no database captures.

What a Real Property Valuation Actually Looks At

A proper valuation — whether that’s a formal appraisal or a comparative market analysis done by an agent who knows the area — works from a different foundation.

It starts with sold data. Not asking prices, not estimated values — homes that have actually sold, in comparable condition, in a comparable location, within a relevant timeframe. In Manitoba, that data lives inside the MLS system. An agent pulling comps for your home is working from information that no online tool has access to.

A good CMA looks at what’s been updated, what hasn’t, and how your home compares to what sold recently — not on paper, but in person. The difference between a home valued by someone who has walked through it and one valued by an algorithm that has only seen its square footage is significant.

It accounts for current buyer behaviour. What’s moving in your price range right now? How many days are homes sitting before offers? Are buyers competing, or are they taking their time? These are things an agent working the market every week knows. An algorithm doesn’t.

Why This Matters Before You List

The number you anchor to before listing matters more than most sellers realize. If you go to market based on an automated estimate that’s working from asking prices instead of sold prices, you may be starting in the wrong place — either too high, which costs you time and negotiating position, or in rare cases too low.

Getting this right at the start is easier than correcting it after the fact. The first few weeks, and at higher price points sometimes longer — is when a listing gets the most organic attention.

Frequently Asked Questions

What is a comparative market analysis (CMA) and how is it different from an online estimate?
A CMA is prepared by a real estate agent using actual sold data from the MLS system — homes that have recently sold in comparable condition and location. Unlike an online estimate, it accounts for condition, current buyer demand, and local nuances an algorithm can’t see. It’s done in person, by someone who has walked through your home.

Do I need a formal appraisal to sell my home?
Not typically. A CMA done by a knowledgeable local agent is usually sufficient for setting a list price. Formal appraisals are more commonly required by lenders when a buyer is financing a purchase — they follow a similar methodology but produce a formal report for the lender.

How long does it take to get a proper home valuation?
A CMA from a local agent is typically done within a day or two of viewing the property and doesn’t cost anything. It’s part of the listing process. If you’re considering selling and want to understand your home’s value before making a decision, requesting a CMA is the right first step.

If your home went to market based on a number that turned out to be wrong, this is worth reading before you decide what to do next:
