Porównawcza analiza rynku AI
An AI comparative market analysis (CMA) uses software to pick comparable sales, adjust for differences between those homes and the subject property, and assemble a pricing report an agent can present to a seller or buyer.

It speeds up work agents used to do by hand in the MLS. The agent is still responsible for the price recommendation and for catching what the data misses.

A CMA is an agent's opinion of likely market price, built from recent sales and current listings. It is not an appraisal. Appraisals are performed by licensed appraisers under professional standards and are what lenders use, while a CMA generally cannot be used to underwrite a mortgage. It also differs from an automated valuation model. An AVM returns a number on its own, while a CMA is a document an agent builds, explains and defends. AI-assisted CMA tools, including MLS-integrated modules and products such as Cloud CMA and the Realtors Property Resource (RPR), follow the same basic steps. First they search for candidate properties by distance, time window and property type. Then they score how similar each candidate is to the subject. Next they adjust each comp's price for differences in size, bathrooms, garage, pool, lot and condition. Finally they reconcile the adjusted prices into a range. Newer features add similarity ranking, photo-based condition scoring and auto-written narratives. Good CMAs include more than closed sales. Active listings show the competition a buyer sees today, pending sales show where the market is heading, and expired or withdrawn listings show prices the market turned down. Several misconceptions are common. More comps are not better if the extra ones are poor matches. Averaging price per square foot misleads, because larger homes usually sell for less per square foot than smaller homes nearby. And software cannot adjust for what is missing from the data, such as a busy road behind the yard, an awkward layout, or hidden deferred maintenance. The agent's walk-through still matters. Generated narrative text also needs checking line by line, because language models can state features confidently that the property does not have. Adjustments should reflect property features and market conditions, never the demographics of a neighborhood.
Implementacja w świecie rzeczywistym
Before a listing appointment, an agent enters the address and the tool pulls about 30 sales of similar property types within a mile from the past six months, ranks them by similarity, and the agent keeps the five closest matches.
A photo-analysis feature scores kitchen and bath condition from listing photos and flags that one comp was fully renovated, so the agent adjusts that sale downward instead of treating it as a direct match.
A buyer's agent runs a quick CMA on a home that has sat on the market for 60 days, using pending and expired listings to support an offer below the asking price.
A generative AI assistant drafts the CMA's written summary explaining the suggested price range, and the agent edits it after catching a sentence that claimed the home had a finished basement it does not have.
The Future of AI Comparative Market Analysis
CMA tools are likely to lean more on photo and document analysis to fill gaps in MLS data, such as condition, finishes and layout, and to produce clearer explanations of why each comp was chosen. That could make pricing conversations more transparent for sellers. The weak points are unlikely to go away soon: thin markets with few sales, unusual properties, and facts that never appear in any database. Brokerages will probably put more effort into review workflows for AI-written narratives, because agents stay responsible for what their reports claim.

Często zadawane pytania
What is AI Comparative Market Analysis?
An AI comparative market analysis (CMA) uses software to pick comparable sales, adjust for differences between those homes and the subject property, and assemble a pricing report an agent can present to a seller or buyer. It speeds up work agents used to do by hand in the MLS. The agent is still responsible for the price recommendation and for catching what the data misses.
Why do strong CMAs include expired or withdrawn listings alongside closed sales?
Expired and withdrawn listings reveal price points where homes failed to sell. That is useful evidence when setting a list price.
Why is averaging price per square foot across comps a misleading way to price a larger home?
Price per square foot tends to fall as size rises, so applying an average from smaller homes to a larger one overstates its value.
A comp closed five months ago and the local price index has risen 3 percent since then. What adjustment does an AI CMA typically make?
Time adjustments use a local price index to bring older sale prices up to current market conditions.
A regression-based CMA tool assigns an extra bedroom a negative value. What is the most likely reason?
When two inputs are strongly correlated, regression can split their effects in odd ways, producing coefficients that make no sense alone. That is why tools often constrain them.
During reconciliation, which comps should get the most weight?
Comps needing small gross adjustments are the closest matches, so they are the most reliable indicators of the subject's value.
