Three tools, three different numbers. Many Markham homeowners check an online estimate, hear a different figure from a neighbour's agent, and then see a third number on a bank appraisal. It is confusing, and it matters, because the number you believe shapes every decision after it.
As one of the busier teams working Markham and York Region every week, the Kaizen Real Estate Team sees all three side by side. Here is what each one measures, where each one goes wrong, and which one to use for your situation.
The Online Estimate: Fast, Free and Blind
Online estimates use algorithms that look at public sales data, property records and broad trends. They are instant and useful for curiosity.
The problem is what they cannot see. They do not know about your new kitchen, your finished basement, the ravine behind your lot, or the busy road two doors down. In neighbourhoods with mixed housing, like parts of Unionville or Markville, the gap between an online estimate and a real sale price can be large.
Use it for: a rough sense of direction. Do not use it for: setting a list price.
The Comparative Market Analysis: How Sellers Set a Price
A CMA is prepared by a REALTOR® to answer one question: what will a buyer likely pay for this home right now? It compares your home with recently sold, active and expired listings nearby, then adjusts for differences.
| Factor | How a CMA handles it |
|---|---|
| Size and layout | Adjusted against similar homes that sold |
| Condition and upgrades | Seen in person, then priced |
| Lot and location | Backing, frontage and street compared |
| Market direction | Days on market, inventory and sale-to-list trends |
A good CMA also shows scenarios: value as-is, after cosmetic updates, and after bigger improvements. That helps you decide whether to spend before selling. The Kaizen Real Estate Team prepares a free CMA for Markham homes.
The Appraisal: A Formal Opinion for Lenders and Legal Matters
A formal appraisal is completed by a designated appraiser, often a member of the Appraisal Institute of Canada. Lenders order appraisals to confirm a home supports the mortgage. Estates, separations and some tax matters also call for one.
Appraisals tend to be careful and backward-looking. In a rising market, an appraisal may land below the price a buyer agreed to pay. In a flat market, it often lines up closely with a well-built CMA.
PARTNER PERSPECTIVE
Why the Walkthrough Changes the Number
Neeraj Moolchandani often sees the biggest value gaps in homes that look ordinary online. A finished basement with a separate entrance, a south-facing yard or a quiet crescent can move a price in ways no algorithm catches.
That is why Neeraj Moolchandani asks to see the home before finalizing any valuation. Ten minutes inside tells more than any database can.
Why the Three Numbers Differ
- Timing. Appraisals and algorithms lean on past sales. A CMA also weighs what is happening this month.
- Purpose. A lender wants a safe value. A seller wants the most likely market price.
- Eyes on the home. Only a CMA and an appraisal involve someone actually seeing the property.
- Comparable choice. Two professionals can pick different comparables, which is why the reasoning matters as much as the number.
Which One Do You Need?
| Your situation | Best tool |
|---|---|
| Just curious | Online estimate, then a CMA if you want accuracy |
| Thinking of selling in the next year | CMA |
| Refinancing or a lender request | Appraisal |
| Estate, separation or legal matter | Appraisal, often with a CMA for sale planning |
| Deciding whether to renovate or sell | CMA with scenarios |
