FAQ
What’s the main difference between Altos Research and these alternatives?
Altos Research specializes in weekly-updated listing data (active listings, price reductions, days on market) for near-real-time market conditions. Many alternatives—such as Redfin and Zillow—also offer weekly data but with broader feature sets (rentals, affordability, historical trends). Others like CoreLogic and Black Knight focus more on property valuations, lending, or enterprise-scale integrations rather than inventory tracking alone.
Which alternative is free?
Redfin Data Center and Zillow Research both offer free, publicly available market data without requiring a subscription. NAR Research also publishes many reports and datasets for free or at a low cost for members. The trade-off is that free tools often lack granular, real-time showing-activity data that paid platforms like Altos Research provide.
Can I get showing activity data from these alternatives?
ShowingTime+ MarketStats includes showing activity and buyer demand metrics because it integrates with MLS appointment and feedback data. Altos Research also emphasizes showing data. Most other alternatives (Redfin, Zillow, CoreLogic, ATTOM, NAR) focus on sales outcomes, inventory, and property characteristics rather than live showing activity.
Which platform is best for appraisers?
HouseCanary and CoreLogic both serve appraisers well. HouseCanary provides valuation support and comparable property data, while CoreLogic offers comprehensive property data and market analytics. Both platforms integrate into appraisal workflows and deliver data at the neighborhood and property level needed for income and sales approaches.
Do these platforms integrate with MLS?
CoreLogic and ShowingTime+ MarketStats have direct MLS integrations. ATTOM Data and Zillow Research pull data from public records and MLS feeds but don’t replace MLS software. Redfin Data Center is a standalone reporting tool. HouseCanary, NAR Research, and Black Knight focus on data delivery and analytics rather than MLS platform integration.
