The Verdict
CoStar is built for commercial brokers and property investors, with a focus on property-data and market-analytics. Google Ads targets businesses of all sizes and ecommerce stores and leads with search-ads and display-ads.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Neither tool offers a free plan, so factor the subscription cost into your decision from the start.
Feature-wise, Google Ads offers broader built-in capabilities (8 features vs 7), while CoStar takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
