HouseSigma Review : Is It Just Zillow For Canadians?

By Heidi Unrau | Published on 07 Feb 2024

HouseSigma Review

HouseSigma is a real estate website and app that gives detailed information about homes for sale, including estimated market values, historical sale prices, and neighbourhood trends. It uses artificial intelligence and big data analytics to analyze real estate data. HouseSigma is a powerful tool that can help you make more informed decisions when buying or selling properties. You can search for properties, view property details, and get insights into market trends directly through the platform. I tested HouseSigma to see if this homegrown Canadian platform is just Zillow for Canadians or if it’s a unique offering in its own right. Here’s what I found.

At a glance

HouseSigma offers detailed coverage of the Canadian real estate market. Standout features include home valuations, comprehensive sold history data, rental cash flow analysis, and a user-friendly interface. However, it lacks transparency regarding its valuation error rates and its database is less extensive outside of major real estate markets.

How Much Does HouseSigma Cost?

Nada. Zip. Zero! The platform provides tons of tools that are accessible for free to anyone looking for property insights in Canada. Whether you’re searching for a home, analyzing market trends, or seeking property valuations, HouseSigma doesn’t charge you a dime. Oh, happy day!

How to use HouseSigma

You do need to sign up to use HouseSigma. But there’s no initial cost, and you only need to provide an email address and set up a password. If you’re using HouseSigma online, just head to the HouseSigma website to get started. If you want to use the app on your mobile device or tablet, you’ll need to have something with iOS. The full name of the app is “HouseSigma Canada Real Estate.”

Once you’re logged in, you can easily lose a few hours looking at all their data! Things like properties sold below purchase price, properties sold for high returns, information on properties just sold, and much, much more. Let’s look at this example of a beautiful house in Brampton. Just by clicking on the thumbnail of the listing on HouseSigma, we see the following information:

It’s easy to see the listing price, HouseSigma’s estimated price, and the purchase history for the home. Further down the page, there’s information about comparable houses in the neighbourhood and what they sold for, comparable rentals, real estate statistics for the community, and you can even schedule a viewing.

This listing was found using a general map search for the Greater Toronto area. You can also do searches for a specific property. Or just zoom right into your perfect neighbourhood and get to know what’s available and for how much.

What’s the Catch?

At the time of writing, HouseSigma is only available in Ontario, Alberta, and British Columbia. Don’t live in those areas? Unfortunately, HouseSigma won’t be much help. However, you can still use the app to look up sale prices in those provinces. Bonus, HouseSigma will help you feel better about living in a lower-cost-of-living area. (Raise your hand if you’ve ever felt personally victimized by Canadian real estate prices!).

Here’s what you’ll see if you’re not in one of HouseSigma’s targeted areas. We’ve got BC as an example this time. Although some areas outside of Greater Vancouver have a few data points, it’s not enough to gain any useful knowledge, especially for high-demand markets like the Okanagan.

By contrast, Ontario (with a good overview here of the distribution of results extended from Toronto) can let you conduct a much more detailed search and compare quite a few areas:

Here’s another example: I live in Winnipeg, Manitoba. But when I was a teenager, I lived in Cambridge, Ontario, which is in the Greater Toronto Area. I was curious to know if my old house was on the app. So I toggled to my neighbourhood and, sure enough, there was historical market data for my old house!

My parents sold this house in 2008, fetching just over $200K. In 2022, the house sold for $731K, a whopping $114K over list price!

Now let’s pretend I am an investor looking for a rental property. I just scroll down the listing to find rental information;

An Assessment vs a Valuation: What’s the Difference?

An assessment determines a home’s value for property taxes, set by local authorities. It considers the home’s location, replacement cost, renovations, and local sales trends. Lower assessments mean lower property taxes. Homeowners can challenge or request reassessment, especially if refinancing.

A valuation estimates a home’s current selling price, often higher than its assessment in Canada. It’s based on the property’s condition, size, amenities, local sales, and market trends. Prices vary with market conditions: higher in a seller’s market and lower in a buyer’s market.

In summary, ‘assessed value’ is for taxes, while ‘market value’ is what buyers are willing to pay.

How to Get a House Valuation

If you’re a homeowner in Canada, there are a few ways to get a house valuation. Note that we’re talking about a formal valuation or market value that can be used to set a sale price, refinance a mortgage, get a secured line of credit, or use it for investors.

Many real estate brokers offer an appraisal service to their clients. This is primarily used for setting sale prices. If you’re going to do this, be sure to use a reputable firm and an experienced agent.

You can also hire an expert to conduct a professional appraisal of your property. This is an individual or company that frequently provides house valuations that can be used for any of the purposes listed above. It’s much more in-depth than an online valuation like you’d get with HouseSigma and will be accepted by financial institutions and insurance agencies.

Pros & Cons of HouseSigma

🟢 Comprehensive Data: HouseSigma offers a wealth of data on the Canadian real estate market, making it a valuable resource for buyers, sellers, and investors alike.🔴 Accuracy Limitations: While HouseSigma uses sophisticated algorithms to provide accurate home valuations, the results may not always reflect the actual market value of a property.
🟢 User-Friendly Interface: The platform’s user-friendly interface makes it easy for users to search for properties, view home valuations, and analyze market trends.🔴 Limited Market Coverage: At the time of writing, HouseSigma’s coverage may be limited to Ontario, Alberta, and British Columbia
🟢 Cash Flow Analysis: The cash flow analysis feature is an invaluable tool for real estate investors, allowing them to evaluate the profitability of potential investment properties.

HouseSigma vs Zillow: Comparing Their Algorithms

Zillow focuses on the U.S. market, offering the ‘Zestimate’ for home valuations, with a 1.9% median error rate for on-market homes. Approximately 80% of homes sell within this error margin.

HouseSigma, on the other hand, specializes in the Canadian market, making it more suitable for Canadian users. However, HouseSigma doesn’t disclose its error rates or how closely its valuations match sale prices. Despite potentially less accurate data, some agents trust HouseSigma’s evaluations.

Algorithms for valuations differ and companies keep specifics confidential. After all, that proprietary information is their bread and butter. Generally, more data points lead to more accurate valuations.

HouseSigma’s coverage includes detailed sold history from 2003 for the Greater Toronto and Vancouver areas, and from 2018 for Ottawa and the rest of Ontario, showing its potential for expansion across Canada.

HouseSigma vs Other Platforms

As you weigh your options, you may wonder how HouseSigma stacks up against its competitors. Let’s embark on a side-by-side comparison of HouseSigma with other leading real estate platforms to help you make an informed decision.


Zolo is another popular Canadian real estate platform, offering features such as map search and home valuations. Zolo’s focus on the Canadian market makes it a strong competitor to HouseSigma. However, HouseSigma’s cash flow analysis for investors sets it apart from Zolo.


Zoocasa is a Canadian real estate platform that offers similar features to HouseSigma, including map search and home valuations. Zoocasa also provides mortgage and insurance services. While both platforms offer valuable insights into the Canadian housing market, HouseSigma’s cash flow analysis for investors gives it an edge for those looking to invest in real estate.

When to Use HouseSigma

We agree with HouseSigma’s reviews by real estate agents. It’s an excellent tool for everyone living in coverage areas to find out what comparable houses in an area sold for, learn about trends in your neighbourhood, and get their online valuation if you’re a homeowner. When it comes to the whole house-buying process, every dollar in savings means can add up to savings on your mortgage interest fees.

Even when you’ve found the best mortgage rate possible, the price you pay for your house is likely the biggest cost of your lifetime. And HouseSigma provides a helpful service that makes you a more informed buyer.

Sellers can also get valuable information from HouseSigma. That valuation is your starting point for everything from finding the right listing agent to negotiating effectively. It might even give you some insight into improving your home’s market value!

We’re pleased to see this app gaining ground in the Canadian market. Anything that puts power into the hands of everyday Canadians is a good thing, and that includes HouseSigma. Plus, there’s absolutely no risk in giving it a try. I cannot wait until HouseSigman expands to all regions in Canada.
