If you're a real estate wholesaler or investor trying to find off-market deals before the competition, you've probably looked at PropStream. It's one of the most well-known property data platforms in the industry, and for good reason. But is it the best way to actually find deals that are ready to move on right now?
In this comparison, we'll break down how PropStream and Kaizen Data approach deal discovery differently, what each one costs, and which one makes more sense depending on where you are in your investing journey.
What Is PropStream?
PropStream is a property data and analytics platform that gives real estate professionals access to over 160 million property records across the United States. It pulls data from MLS records, county recordings, and private data sources, and lets you filter properties using over 120 search criteria.
You can use PropStream to find pre-foreclosures, absentee owners, properties with tax liens, vacant homes, and dozens of other motivated seller indicators. It also includes MLS comps, a rehab calculator, and marketing tools like direct mail and skip tracing (available as add-ons or included depending on your plan).
PropStream's plans start at $99 per month for the Essentials tier, with Pro at $199 per month and Elite at $699 per month for larger teams. All plans come with a 7-day free trial.
What Is Kaizen Data?
Kaizen Data takes a completely different approach to finding deals. Instead of giving you a database of properties to search through manually, Kaizen automatically monitors hundreds of Facebook groups in your market and uses AI to identify real estate opportunities as they're posted.
When someone posts "need to sell my house fast, DM me" in a local community group, or a wholesaler drops a deal with "end buyers only, first come first serve" in an investor group, Kaizen's scraper picks it up, classifies it, and delivers it to your feed. You don't have to scroll through groups manually or set up alerts. The leads come to you.
Kaizen also functions as a deal marketplace where wholesalers, agents, flippers, and investors can post and browse deals. So you're getting both automated lead discovery and a community of active investors in your area.
Kaizen is moving toward one Pro workspace with a 7-day trial. Pro gives you real-time scraped leads, marketplace access, buyer/seller matching, filters, contact details, saved workflows, and alerts on new matches.
PropStream vs Kaizen Data: Key Differences
How You Find Deals
This is the fundamental difference between the two platforms.
PropStream is a database. You go to it, type in a zip code or county, apply filters like "pre-foreclosure" or "absentee owner with high equity," and get a list of properties that match. You then research owner contact details, call them, and try to find out if they're actually motivated to sell. Many of those leads will be cold. The property might be in pre-foreclosure, but the owner isn't ready to talk. Or the absentee owner has a property manager and no intention of selling.
Kaizen Data monitors real-time social signals. When someone actively posts about wanting to sell, needing cash buyers, or marketing a wholesale contract, Kaizen catches it. The difference is intent. PropStream tells you which properties might be worth pursuing based on data signals. Kaizen shows you people who are already signaling that they want to make a deal happen right now.
Neither approach is wrong. They're answering different questions. PropStream answers "which properties could become deals?" Kaizen answers "who is actively trying to do a deal right now?"
Data Coverage
PropStream has nationwide coverage with data on over 160 million properties. If you need to pull comps, analyze a property's mortgage history, or check tax records, PropStream is hard to beat.
Kaizen Data's coverage depends on which markets have active Facebook groups being monitored. It launches market by market, with each market having 50 to 100 monitored groups. The leads you get are hyperlocal and tied to real community activity. You won't find every property in America on Kaizen, but the ones you do find come with built-in seller motivation that no database can replicate.
Skip Tracing and Outreach
PropStream includes skip tracing (free with certain plans) and has integrations with BatchDialer for cold calling. Kaizen Data does not currently include skip tracing or a built-in dialer. If a scraped lead includes a phone number in the original Facebook post, you'll see it. But Kaizen is focused on deal discovery and marketplace connections, not outbound calling workflows.
If cold calling is central to your strategy, you'll likely need PropStream or a similar tool alongside Kaizen.
Pricing
PropStream starts at $99 per month with no free tier. The 7-day free trial lets you explore features, but after that you're paying whether you're actively finding deals or not.
Kaizen Data offers a 7-day Pro trial so investors can test the full marketplace, seller lead feed, buyer demand, and contract matching workflow before committing to a monthly subscription.
When to Use PropStream
PropStream is the right choice when you need deep property data for research and underwriting. If you're pulling comps, analyzing rehab costs, checking title history, or building large targeted mailing lists, PropStream's database is one of the most comprehensive available. It's also better for investors who rely heavily on outbound marketing like direct mail, cold calling, and SMS campaigns. PropStream gives you the data to build those lists. You just need to do the outreach yourself.
When to Use Kaizen Data
Kaizen Data is the right choice when you want deals delivered to you instead of hunting for them manually. If you're a wholesaler who spends hours scrolling through Facebook groups looking for FSBO posts, distressed sellers, or other wholesalers dropping deals, Kaizen automates that entire process. It's also ideal for investors who want to connect with other active wholesalers, flippers, and buyers in their market through the built-in marketplace.
For new investors who do not have a big marketing budget for direct mail or cold calling, Kaizen's 7-day Pro trial gives you a way to test live deal flow and buyer matching before committing to a monthly data subscription.
Can You Use Both?
Absolutely, and many serious investors will. The two platforms complement each other well. Use Kaizen to catch deals in real time from social signals that PropStream can't see. Use PropStream to pull comps, verify property data, and run your outbound marketing campaigns. The combination gives you both proactive deal discovery and deep property analytics.
Think of it this way: Kaizen is your radar for active opportunities. PropStream is your research desk for analyzing them.
The Bottom Line
PropStream is a powerful property data platform that excels at research, filtering, and outbound marketing support. It's been an industry staple for years and has a massive dataset.
Kaizen Data is a new kind of tool that surfaces deals you can't find in any property database because they come from real-time social activity. It's built for investors who want automated deal discovery and a marketplace to connect with other active players in their market.
If you're spending hours every week scrolling through Facebook groups looking for deals, Kaizen automates that work for you. If you're building cold call lists from property records, PropStream is the tool for that job. And if you want the best of both worlds, there's no reason you can't use them together.
