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. The lines are blurring: InvestorBase now advertises comps and deal landing pages, and PropStream added a $70/mo add-on for finding investors near a property in October 2026.

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 AI SmartMatch ranks these buyers by their past investing behavior, skip tracing is free on every plan, and its home page also advertises ARVs from MLS-backed comps and deal landing pages. 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, then mail, call or drive for dollars with its mobile app. The output is a list of properties to market to for acquisitions. Since October 22, 2026 it also sells Investor Outreach ($70/mo, requires Connect), which shows investors who bought near a property.

Feature comparison

Can you use both?

Yes, and many wholesalers do. The workflow looks like this:

1. PropStream for acquisition: Build lists of motivated sellers, skip trace them, send direct mail or make calls to get properties under contract.
2. 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 $398/month on monthly billing (PropStream Essentials $99 + InvestorBase $299), or $348/month if you pay InvestorBase quarterly ($99 + $249, billed $747 every 3 months). Add $30/mo for PropStream Connect if you want free skip tracing on the seller side; InvestorBase's buyer skip tracing is already free. 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 and finding buyers, and both now offer some comp analysis and ARV work. What's left is narrower than it used to be:

• Repair estimates — PropStream has a rehab calculator where you type in costs; InvestorBase doesn't list repair estimation on its site
• Two separate systems — your seller data lives in one tool and your buyers in the other, with no data flow between them
• Sending the deal — InvestorBase says it connects to your CRM, SMS and dialer rather than listing a built-in email blast, so check how you'd send a deal to its buyers before you buy

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
• You want free buyer skip tracing and deal landing pages in the same tool

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 is our product, so weigh this section accordingly. Deal Run includes buyer identification (like InvestorBase), comp analysis, AI repair estimation from the property's photos (which neither lists), built-in skip tracing, deal marketing pages, and sending the deal from your own Gmail — all for $99/month on Analyze + Sell ($83/mo billed annually), or $29/month for analysis only on Analyze. Text blasts go out from your own number.

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 sending steps in one place. It is a newer, smaller tool than either, with no dialer, no direct mail and no driving for dollars.

The bottom line

InvestorBase and PropStream are complementary tools that cover different stages of wholesaling. Using both costs $398/month on monthly billing ($348/month with InvestorBase quarterly) and covers acquisition and buyer identification in two separate systems. Pick PropStream if you need more deals, InvestorBase if you need more buyers, and look at a combined tool only if you want analysis and buyer search in one place for less.
