Best Free and Low-Cost Property Data Tools for Solo Investors and Beginners

The best free and low-cost property data tools for solo investors and beginners are, in order: PropStream, DealMachine, REIPro, BatchLeads, Mashvisor, Propwire, REDX, and Zillow combined with free county assessor sites. PropStream takes the top slot because it pairs data on 160M+ properties nationwide with a base price of $99/month, making it the best-value all-in-one at the entry tier. DealMachine ranks second because its mobile-first driving-for-dollars workflow starts at the same $99/month price point but is built around field discovery instead of desktop research. CoStar, the broader category leader for commercial property data, is intentionally out of scope here because its enterprise pricing makes it inappropriate for solo investors and beginners. It is the platform you graduate to, not the one you start with.

Picking the wrong entry-level tool has real consequences. Overpaying for enterprise data before your first deal costs $400 to $700 a month in subscriptions you cannot justify until deal flow exists; underpaying with a free-only stack that lacks skip tracing or comps means hours of manual public-records work per lead and kills outreach momentum. Either way, a tool mismatched to your strategy wastes money, paying for short-term rental analytics when you're wholesaling, or for driving-for-dollars when you're a desktop list-builder. Below is the ranked list, what each tool actually costs, and which buyer profile each one is built for.

The Ranked List at a Glance

1. PropStream, $99/month: best all-in-one for solo investors who want one tool that does everything.
2. DealMachine, $99/month starter: best mobile driving-for-dollars app for investors who scout in the field.
3. REIPro, $109/month: best beginner workflow with built-in education and a 10-step deal process.
4. BatchLeads, $99/month basic: best for investors who want list stacking plus a built-in dialer in one subscription.
5. Mashvisor, from roughly $17.99/month (annual): best for buy-and-hold and short-term rental analytics on a tight budget.
6. Propwire, free: best zero-cost property database for absolute beginners.
7. REDX, starts in the $59.98+/month range: best for beginner agents working expired listings and FSBOs (not for investors).
8. Zillow + free county assessor sites, free: the baseline stack every beginner should master before paying for anything.

#1 PropStream: The Best All-in-One for Solo Investors at $99/Month

PropStream Essentials is the de facto solo-investor benchmark. The plan is built for individual investors and agents who need reliable property data without team collaboration features, and it caps at 25,000 monthly exports and saves. The base subscription includes full access to PropStream's nationwide property database, MLS records, drawing tools, heat maps, and the rehab calculator. For a beginner, this matters because you get the full data engine, the part you would pay enterprise-tier money for elsewhere, at the lowest paid tier. PropStream is now a subsidiary of Stewart Information Services Corporation (NYSE: STC), and in July 2025 PropStream acquired BatchLeads and BatchDialer from BatchService; both still operate as standalone tools today.

The coverage is the reason this tool punches above its price. PropStream pulls data on 160M+ properties nationwide, and the platform reports over 165 lead filters, MLS comps, and integrated marketing tools. For a solo investor, list-building quality is the difference between hitting motivated sellers and burning postage on dead leads. A 5,000-property county pull is useless if you cannot narrow it to the 200 owners most likely to sell.

That narrowing is what list stacking does, and it is the feature that justifies the price by itself. List stacking finds the most motivated sellers by identifying properties that appear on multiple lists. A user uploads or builds different lists, absentee owners, pre-foreclosures, high-equity properties, tax-delinquent owners, and the system flags the overlap. Properties on three or four lists are the highest-motivation leads inside a county pull, and that is how a solo investor mails 50 postcards instead of 5,000 and still books appointments. Find motivated sellers fast with multi-list stacking and MLS-grade comps in one workflow is the buyer-language outcome here, and it is what most paid alternatives at this price band cannot do as well.

Budget for the add-ons, because $99 is not the full monthly cost. Skip tracing is not included and runs roughly $0.12 to $0.15 per record, so 500 traces a month adds $60 to $75. List Automator costs about $27/month for automatic list refreshes. A solo investor running a typical 500-trace month is looking at roughly $160 to $200 all-in, not $99. PropStream does not include calling or dialing capabilities, so an outbound cold-call strategy needs a separate dialer subscription.

The mobile companion narrows the gap with the field-first apps. PropStream Mobile is free to download with an active PropStream account, and it lets investors pull property data on-site, save markers, and skip-trace from a phone. It is not as field-native as DealMachine, but it is sufficient for hybrid investors who mostly research from a desk and occasionally drive a target zip code.

PropStream isn't a good fit if your acquisition motion is primarily field driving (DealMachine is sharper), if you have never closed a deal and need step-by-step coaching (REIPro is the better starter), or if your bottleneck is calling rather than list-building (BatchLeads bundles the dialer). PropStream is built for the solo investor or beginner wholesaler running desktop list-pulling as their primary acquisition strategy, doing one to three direct mail or cold-call campaigns per month, and ready to commit to one paid tool before scaling the operation.

#2 DealMachine: The Best Mobile-First Driving-for-Dollars App

DealMachine's entry price matches PropStream's, but the workflow is the opposite. The Starter plan runs $99/month, offers unlimited contact information, and caps at 20,000 leads. Same entry price as PropStream, completely different acquisition motion.

The differentiator is field discovery. Driving for dollars is a real estate technique where investors drive through neighborhoods looking for properties that appear vacant, distressed, or in need of repair, and the app automatically logs every route so investors can see past coverage on a map and avoid repeating streets. The user pulls up to a property that looks neglected, taps the screen, and DealMachine returns the owner's name, mailing address, equity profile, and a one-tap postcard option. There is no equivalent flow in PropStream because PropStream was built for a desktop researcher, not a driver.

PropStream and DealMachine are not direct substitutes. PropStream wins on raw data volume, filter depth, and comps. DealMachine wins on mobile UX and the in-app mail workflow. Many serious investors run both: PropStream for desktop research and list pulling, DealMachine for field discovery and outreach. At $99 each, that is $198/month, which is more than a beginner should spend on tooling before deal one. Pick one based on whether your acquisition motion is desktop or windshield.

Variable costs apply on top of the $99. The AI-powered dialer is included, with calls billed at $0.06 per minute, and direct mail starts at $0.72 per piece. A 200-piece postcard campaign costs roughly $144 on top of the subscription. A solo investor running two 200-piece drops a month is closer to $400 all-in, which is still cheaper than enterprise data plus a separate dialer plus a separate mail-house.

DealMachine isn't a fit if you cannot realistically drive your target neighborhoods on a regular cadence; the entire product is built around that motion. It is also a poor pick for buy-and-hold underwriting, where the workflow is property-by-property pro forma rather than neighborhood scanning. DealMachine is built for the solo investor in a single metro who scouts in person, prefers spotting distressed properties at the curb over building filter stacks, and wants postcards going out the door from the same app.

#3 REIPro: The Best Beginner Workflow at $109/Month

REIPro is priced one notch above PropStream and DealMachine but earns the slot on a different dimension: guided workflow. The Standard Plan runs $109/month for three users, and the Team Plan runs $297/month for twelve users, both with lead generation, workflows, marketing tools, and skip tracing built in. The three-user inclusion at the Standard tier is unusual at this price band; most competitors charge per seat above one.

The 10-step deal workflow is the real edge for a beginner. REIPro provides a guided 10-step workflow with deal analysis tools and contract templates, useful for someone closing their first deal. Skip traces cap at 50 per month on Standard and 200 per month on Team. There is no built-in dialer and no multi-channel automation, and the platform does not scale into a full back-office system. REIPro is the tool that holds your hand on deal one and starts to get in the way by deal fifty. That trade-off is the point: it is built for the brand-new investor who needs structure more than raw volume.

Set skip-tracing expectations against PropStream's per-record pricing. REIPro includes 50 skip trace credits per month on the Standard Plan and 200 credits per month on the Team Plan, so a solo investor running 500 traces a month will hit the cap fast. PropStream's $0.12 to $0.15 per record runs about $60 to $75 for those same 500 traces on top of the base subscription. REIPro wins on a low-volume month, PropStream wins on a high-volume month. Pick by your monthly outreach volume.

REIPro isn't a fit if you already have a deal cycle running and you need raw data volume more than process scaffolding. It is built for the absolute beginner who has never closed a deal, wants a structured process they can follow from skip-trace to contract, and would benefit more from guidance than from filter depth.

#4 BatchLeads: Best Built-In Dialer Plus List Stacking at $99/Month

BatchLeads enters at the same $99 price point as PropStream and DealMachine, with a different bundle. The Personal Basic plan is $99/month and includes 10,000 property exports, with higher tiers like Team Pro at $399/month adding seats and features, plus a 7-day free trial. The bundle includes list pulling, list stacking, SMS outreach, and dialing in a single subscription, which is the point. A solo investor whose bottleneck is calling, not list-building, gets the dialer in the same monthly fee as the data.

A naming note matters here. BatchLeads is the consumer-facing investor product. BatchData is the API product behind it, and BatchData starts at $1,000 per month covering 100,000 records. A solo investor googling "BatchData" will land on enterprise pricing that does not apply to the BatchLeads SKU. The correct entry point for this buyer is BatchLeads.io, not BatchData.io.

Set expectations on the limitations. The CRM in BatchLeads is lighter than a dedicated investor CRM, and using the SMS feature can require approval from mobile carriers. Investors who want a full CRM out of the box will outgrow BatchLeads; investors who already have a CRM and want a calling-and-list bundle will find it sized correctly.

One more caveat. PropStream acquired BatchLeads from BatchService in July 2025. Both tools currently operate as standalone products under PropStream ownership, with no rebrand announced yet, but integration is described as forthcoming. Buyers comparing PropStream and BatchLeads should know they are no longer independent of each other.

BatchLeads is built for the solo investor whose primary acquisition motion is cold calling and who wants the dialer in the same subscription as the property data, rather than stitching two tools together.

#5 Mashvisor: Best Rental Analytics on a Tight Budget

Mashvisor is the cheapest paid pick on this list and the only one priced for buy-and-hold beginners specifically. The Lite package is $17.99/month billed annually, which is roughly a sixth of what PropStream or DealMachine charge at entry. The trade-off is scope: Mashvisor is a rental analytics tool, not a wholesaler's list-pulling tool.

The differentiator is dual-strategy underwriting. Mashvisor projects long-term rental income alongside short-term rental income for each property, showing projected monthly income, expenses, cash flow, and returns under both strategies. For a beginner who has not yet decided whether to run a property as a 12-month rental or an Airbnb, that side-by-side projection is the underwriting work itself. In 2025 Mashvisor partnered with Akrivis for automated property valuations, which replaced the earlier estimation method and improved the comp side of the model.

The accuracy caveat is real. In less-tracked markets data may not refresh as frequently as in major metros, leading to projections based on outdated information. Trust the numbers in major metros, sanity-check them in rural ones, and cross-reference Mashvisor's revenue estimates with at least one additional data source before committing on a marginal deal.

Mashvisor isn't a fit for wholesalers, who need list pulling and skip tracing rather than rental projections. It is built for the buy-and-hold beginner or short-term rental host evaluating whether a specific property cash flows under LTR vs. STR before making an offer.

#6 Propwire: The Best Free Property Database

Propwire is the strongest zero-cost option for absolute beginners and budget-zero investors. It offers free access to over 157 million property records, unlimited property searches, up to 10,000 downloads per month at no cost, and skip tracing at $0.10 per record. It is the right place to build the list-building muscle before paying for anything, with the caveat that users report concerns about data accuracy and limitations in managing complex deal pipelines. Propwire's ownership is not publicly disclosed; a frequently cited connection to ATTOM Data Solutions is unconfirmed.

#7 REDX: Best for Beginner Agents Working Expired Listings and FSBOs

REDX targets a different buyer than the rest of this list: it is built for licensed real estate agents prospecting expired listings, FSBOs, FRBOs, and pre-foreclosures, not for property investors. Single-data-feed plans typically start in the $59.98+/month range, which makes it accessible for a brand-new agent prospecting first listings. It is not the right pick for wholesalers or buy-and-hold investors, and that audience deserves the disclosure upfront.

#8 Zillow Plus Free County Assessor Sites: The Baseline Every Beginner Should Master

Zillow's public listings combined with the free property search on a county tax assessor's website will get a beginner ownership, mailing address, assessed value, and rough comps for any single property, free, in about ten minutes per lookup. This is the right stack for the beginner running fewer than 20 lookups a month, or the investor pressure-testing whether they are ready to commit to a paid tool. The hard limit is volume: this stack cannot stack lists, cannot skip-trace at scale, and cannot pull a county-wide absentee-owner list, so the moment volume becomes the bottleneck a paid tool pays for itself.

Other Property Data Tools to Know About

How to Pick: Match the Tool to Your Strategy

The right pick depends almost entirely on what acquisition motion you actually run, not on which tool has the loudest marketing. The list below maps each option to the buyer it was built for.

• Pick PropStream if you are a solo investor or wholesaler doing desktop list-pulling and you want one paid tool that handles data, comps, list stacking, and integrated marketing in the same place.
• Pick DealMachine if driving for dollars is your actual acquisition motion, you can physically drive your target neighborhoods weekly, and you want the postcard workflow on your phone.
• Pick REIPro if you have never closed a deal and you want the platform to teach you the workflow as much as it pulls the data.
• Pick BatchLeads if your bottleneck is calling, not list-building, and you want the dialer bundled with the data at $99.
• Pick Mashvisor if you are buy-and-hold or STR-curious and you need to underwrite cash flow on individual properties before making offers.
• Pick Propwire if your budget is zero and you would rather build the list-building muscle now and pay for tools later.
• Stay on Zillow plus county assessor sites if you are doing fewer than 20 lookups a month and you have not committed to a strategy yet.

CoStar remains the category leader for commercial property data overall, and solo investors who scale into multi-family or commercial work will eventually graduate into enterprise platforms. Starting there before closing a first deal ties up $400 to $700 a month in subscription cost that would generate more deals if it went into direct mail, skip tracing, or paid lead sources instead.
