Every buyer wants to know they paid the right price for their home. But without the right data in front of you, making an offer is little more than guesswork. Real estate comparables, often called comps, are the tool that removes the guesswork entirely. Understanding what they are, how to read them, and how to ask your realtor to pull them is one of the most valuable things you can do before you ever put pen to paper on an offer.
What Are Real Estate Comparables (Comps)?
Real estate comparables are recently sold properties that are similar to the home you are considering buying. The comparison is based on location, size, age, condition, and features. When your realtor pulls comps, they are building a picture of what buyers in the real market have actually paid for homes like the one you want. Not asking prices. Not estimates. Actual sold prices.
Good comparables share several key characteristics with the subject property: they are within the same neighbourhood or a comparable area, they sold within the last 60 to 90 days, they are similar in square footage (typically within 10 to 15 percent), they have a similar number of bedrooms and bathrooms, and they are in comparable condition. The closer the match across all these factors, the more useful the comp.
What Is a Comparative Market Analysis (CMA)?
A Comparative Market Analysis, or CMA, is a formal report your realtor prepares using comparable sold data. It goes beyond a single number and shows you the full picture: what similar homes sold for, how long they sat on market before selling, what the average sale-to-list ratio was (whether homes sold above, at, or below asking price), and what is currently active or pending in the same area. A well-prepared CMA gives you a defensible price range for the home you want to buy so that your offer is grounded in real evidence, not intuition.
Your realtor has access to the MLS sold database, which is not publicly available. This is a significant information advantage. The seller's agent has already run this analysis. If you walk in without it, you are negotiating blind.
Why Buyers Need Comparables Before Making an Offer
A listing price is what the seller wants. A sold price is what the market decided. Those two numbers are often very different, and the gap between them is where buyers either protect themselves or lose money.
Without comparables, you have no way to evaluate whether the asking price is fair, high, or low. You cannot assess how much negotiating room exists. You cannot structure a competitive offer with confidence in a multiple-offer situation. And you cannot defend a lower offer with any credibility if the seller pushes back.
Comparables also reveal market conditions. If recent comps show homes selling 3 to 5 percent over asking in two to three days, you know you are in a competitive environment and need to act accordingly. If homes are selling below asking after 30-plus days on market, you have negotiating leverage and time to use it.
Always ask your realtor for comparables before you make an offer, not after. Once you are emotionally invested in a property, it is much harder to walk away if the data does not support the price. The comps should inform your decision, not confirm it after the fact.
What to Ask Your Realtor Before You Make an Offer
A good buyer's agent will pull comps automatically before advising you on an offer price. If they do not, ask directly. Here are the specific questions worth asking:
What have similar homes sold for in this neighbourhood in the last 60 to 90 days? This is the core of the CMA. You want to see actual sold prices, not active listings.
What is the average sale-to-list ratio in this area right now? If homes are consistently selling at 98 percent of asking, that tells you something different than if they are selling at 103 percent. This number tells you how to frame your offer.
How long are similar homes sitting on market before they sell? Days on market is a signal of demand. Short days on market means competition. Long days on market means you have time and leverage.
Is there anything that makes this property harder or easier to compare? A home with a legal suite, a lot that is significantly larger than neighbours, or a recent full renovation may justify a different price than a straight comparable analysis suggests. Your realtor should be able to speak to these adjustments.
Using Comparables to Negotiate the Right Price
Comparables are not just a pre-offer research step. They are a negotiating tool. If the comps clearly support a price below asking, your realtor can present that data in the offer to give your position credibility. Sellers and their agents respond to evidence. An offer with a well-supported rationale is taken more seriously than an identical number presented without context.
In competitive situations, comparables serve a different purpose: they give you a ceiling. Knowing what the market has actually paid for similar homes helps you decide how far above asking you are willing to go, and where you need to walk away. Overpaying in a multiple-offer situation because you did not know where the market actually was is one of the most common and most avoidable mistakes Calgary buyers make.
Your realtor's ability to pull, interpret, and act on comparable sales data is one of the clearest differences between good representation and average representation. Before you make an offer on any home in Calgary, ask your agent to walk you through the comps. The conversation will take 15 minutes and could save you tens of thousands of dollars.
