InvestorBase vs PropStream: Buyer ID vs Property Data
InvestorBase and PropStream are both popular tools for real estate investors, but they answer fundamentally different questions. InvestorBase answers "WHO is buying investment properties near my deal?" PropStream answers "WHAT properties should I try to buy?" These are complementary functions, not competing ones, though budget constraints often force wholesalers to choose.
What each platform focuses on
InvestorBase: finding buyers
InvestorBase is a buyer identification tool. Enter a property address, and it searches public records to identify active investors in the area — both landlords (absentee property owners) and flippers (short hold period sellers). Its Investor Score ranks these buyers by relevance based on proximity, recency, price match, and activity level. The output is a list of people to contact about your deal.
PropStream: finding deals
PropStream is a property data platform. It provides access to property records, ownership data, and distress indicators for building targeted seller lead lists. Stack filters for absentee owners, pre-foreclosures, tax delinquent properties, and high equity to find motivated sellers. The output is a list of properties to market to for acquisitions.

Can you use both?
Yes, and many wholesalers do. The workflow looks like this:
- PropStream for acquisition: Build lists of motivated sellers, skip trace them, send direct mail or make calls to get properties under contract.
- InvestorBase for disposition: Once you have a deal, search for active investors near the property, skip trace them, and reach out with your deal.
The combined cost is $348/month ($99 + $249), plus skip trace costs for both platforms. This gives you a complete acquisition-to-disposition workflow, though the two platforms don't integrate — you're managing separate systems with no data flow between them.
The gap in the middle
Using PropStream and InvestorBase together covers finding deals (step 1) and finding buyers (step 4), but leaves the middle of the workflow uncovered:
- Deal analysis — neither provides robust comp analysis, ARV calculation, or repair estimation
- Deal marketing — neither creates shareable deal pages or marketing materials
- Buyer outreach — neither includes email blast or SMS tools for contacting identified buyers
These gaps mean you need additional tools (or manual processes) to complete the disposition workflow, adding more cost and complexity.
When InvestorBase makes more sense
- Your biggest challenge is finding buyers, not finding deals
- You already have properties under contract and need to move them
- You're comfortable with your acquisition process and want to focus budget on disposition
- You want to build a proprietary buyer database from public records
When PropStream makes more sense
- Your biggest challenge is finding deals, not selling them
- You already have a buyer network and just need more deal flow
- You rely on direct mail, cold calling, or text campaigns for lead generation
- You need comprehensive property data for market research and due diligence
Consider also: Deal Run
Deal Run bridges the gap between these two platforms. It includes buyer identification (like InvestorBase), comp analysis (better than PropStream's), repair estimation (that neither has), built-in skip tracing, and deal marketing pages — all for $99/month.
Deal Run doesn't replace PropStream's list stacking for acquisition marketing. But if your workflow starts with deals you've already sourced (through networking, referrals, or other channels), Deal Run covers the analysis, buyer identification, and marketing steps that PropStream and InvestorBase combined still leave gaps in.
The bottom line
InvestorBase and PropStream are complementary tools that cover different stages of wholesaling. Using both costs $348+/month and covers acquisition and buyer identification but leaves analysis, marketing, and outreach to other tools. For wholesalers who want to consolidate those middle steps into a single platform at a lower price, alternatives exist that bridge the gap between finding deals and finding buyers.
