Best Property Data Platform for Owner Identity Resolution and Skip Tracing

The best property data platform for owner identity resolution and skip tracing depends on the job. PropertyRadar wins SMB residential skip tracing, because owner phones and emails arrive already matched to the owner record and are metered inside the subscription at 250 to 2,500 contacts a month by plan (PropertyRadar pricing). Reonomy wins commercial real estate LLC piercing, unwinding shell entities across 54M+ U.S. commercial properties (Reonomy overview). CoStar wins institutional CRE owner identity at scale, where ownership sits inside a research subscription and is never priced as a skip-trace product (CRE professionals).

Getting owner identity wrong shows up first as wasted outreach spend, because REsimpli, a real estate CRM vendor, puts contactable rates at 30 to 40% with standard data and 60 to 80% with better tooling (REsimpli accuracy framework), which on a 200-owner list is the difference between 70 conversations and 140. The second consequence is TCPA exposure, because dialing a wrong number without consent carries statutory damages of $500 per violation, trebled to $1,500 when the violation is willful (TCPA statute).

The third is dead-end CRE prospecting, since most commercial assets sit behind an LLC or a trust, and a platform that returns the legal entity leaves a broker with no human to call and no way to start the conversation that the whole list was built for.

Why the Winner Is Split: Three Different Jobs, Three Different Winners

Owner identity resolution covers three separate buying jobs, and buyers who treat them as one end up paying for a platform built for someone else's list. A residential wholesaler judges a tool by contacts reached per dollar, while a CRE broker judges it by whether an LLC resolves to a person with a phone number, so the same coverage claim means something different to each of them.

SMB residential teams need owner contacts without a procurement cycle. Real estate investors, wholesalers, agents, and direct-mail teams need phones, emails, and mailing addresses attached to a list of addresses. The winner is PropertyRadar, which ships owner contacts pre-matched to the owner record and bills them inside a $119 to $599 monthly plan (PropertyRadar pricing). Teams working 100,000 records a month, or embedding skip tracing in a product, should look at BatchData for the only published right-party contact rate in the category, 76% (BatchData skip tracing).

CRE owner prospecting requires unwinding shell entities and trust structures. Brokers, investors, lenders, and service providers need to identify the human behind a commercial parcel, where accuracy is measured by whether you reach the owner or the registered agent. The winner is Reonomy, which tells you who owns a property when the ownership is buried inside a chain of LLCs, then matches every record back to the same property and the same owner.

Institutional CRE teams need owner identity embedded in the property dataset they already license. Enterprise acquisitions, capital markets, and lender prospecting teams work at a scale where a separate skip-trace purchase adds friction. The winner is CoStar, where owner data is one field inside the research subscription and not a separate purchase.

A buyer who reads a generic best-skip-tracing roundup without separating these jobs picks on coverage claims never measured against the same task. Each section below takes one job and states the conditions under which its winner stops being the right answer.

How PropertyRadar Wins SMB Owner Identity and Skip Tracing

PropertyRadar covers 160M+ properties, 318M+ mortgages, and 3,000+ counties, and it sells owner contact as part of the subscription instead of as a separate skip-trace transaction (PropertyRadar homepage). That packaging is what puts it ahead of the pay-per-trace field for residential investors and home-services operators working lists in the low thousands per month.

The owner record underneath the property record

PropertyRadar distinguishes the assessed owner from the person who should receive outreach. Its direct-mail guide defines the Assessed Owner as the owner reported by the county assessor and the Primary Contact as the contact associated with the property (PropertyRadar direct mail).

The owner profile carries mailing address and primary residence address as separate fields, alongside person type, ownership role, and an owner-occupied flag (owner profile guide). PropertyRadar calls the relationship layer OwnerGraph and says it links owners to their properties and documents across sources and over time, which surfaces the other properties an owner holds from one property card (property and owner data).

Phones and emails included in the plan

Every plan carries a monthly allowance of owner phones and emails rather than a per-trace charge. Solo at $119 a month includes 250, Team at $249 includes 500, and Business at $599 includes 2,500, with annual prepay dropping those three prices to $99, $199, and $549 (PropertyRadar pricing).

Overage runs $0.08 per contact on Solo, $0.06 on Team, and $0.04 on Business, and relatives are metered separately at $0.20, $0.15, and $0.10 (phone and email allowances). Unused allowances do not roll over, so an uneven month wastes part of the plan's charge.

Phones carry mobile, landline, or other labels, emails are described as validated, and a search can be filtered to owners with a mobile number and no do-not-call flag before the list is saved (property and owner data). PropertyRadar's framing is that these contacts are pre-matched and skip the extra step of skip tracing, so a saved list arrives with contacts attached and no round trip to a trace vendor.

Entity resolution for LLCs and trusts

PropertyRadar's feature page describes entity resolution as "See the real people behind LLCs and trusts so you can contact the decision maker" (property and owner data). Release notes state the capability more precisely, saying the platform provides contact information for authorized representatives or signatories behind an LLC, a corporation, or a trust (4.9 release notes).

The trust-specific piece is named Trust Breaker, which the company says finds the individuals behind trusts that other services fail to match (skip tracing guide). Both descriptions cover contact for representatives and signatories, which is entity-resolved marketing data and not an adjudicated record of beneficial ownership, and no page states what share of entities resolve to a named human.

What the compliance tooling covers

National DNC screening activates only after a user registers with the National Do Not Call Registry and enters a Subscriber Account Number into the account. Once that SAN is in place, PropertyRadar scrubs previously saved lists automatically and charges nothing for the scrub itself (accessing DNC data).

State-level DNC and known-litigator screening requires a separate Blacklist Alliance subscription the user connects to the account, so the litigator filter advertised on the feature page depends on a third-party service the buyer supplies (account settings). Blacklist Alliance builds that list from numbers and emails disclosed in court cases (Blacklist Alliance integration).

PropertyRadar's user agreement puts TCPA compliance on the subscriber, along with the Telemarketing Sales Rule and state telemarketing laws (user agreement). The FCC's one-to-one consent rule that would have retired blanket consent never took effect, because the Eleventh Circuit vacated it on January 24, 2025 (consent rule vacated), which leaves the older TCPA analysis in force and the screening burden with the caller.

Cost per owner, and the workflow after the match

At 1,000 owner lookups a month, PropertyRadar Solo costs about $179, or $159 on annual prepay, counting the $119 base plus 750 overage contacts at $0.08 for phones only (PropertyRadar pricing). PropStream Essentials at the same volume runs about $219, because skip tracing there is $0.12 per contact on top of a $99 base (PropStream pricing). BatchData publishes no tier below $1,000 a month, so those same 1,000 lookups sit against a subscription floor built for 100,000 records (BatchData pricing).

Dialing, texting, and mail are billed inside the same account, with preview-line dialing at $59 for 1,200 minutes, single line at $99, multi line at $149, SMS packages from $49 for 2,000 messages, and 4x6 postcards from $0.60 to $0.66 by plan (PropertyRadar pricing). Monitored lists can fire those channels automatically when a property changes state, and the help center warns an automation can commit thousands of contacts and a large charge in one pass (phone and email allowances).

Who PropertyRadar is built for, and who it isn't

PropertyRadar is the answer for a residential investor, agent, loan officer, or home-services operator who works a defined territory and wants owner contact attached to a saved list, with outreach on the same invoice. It also fits a small team that wants owner records and dialing under one login, since Team covers three users at $249 and Business covers ten at $599 (PropertyRadar pricing).

PropertyRadar publishes no audited match rate and no right-party-contact rate for its owner contacts. The only percentage on the domain is a blog line saying customers have reported accuracy of 80% or better, offered without methodology or date (skip tracing guide), so a buyer comparing published accuracy has nothing to weigh against BatchData's 76% figure.

Litigator scrubbing runs on a Blacklist Alliance account the buyer subscribes to separately, so the filter is an integration and not a native feature. Contacts are metered, which means a 5,000-owner list on Solo burns the included 250 in one afternoon and bills the remaining 4,750 at $0.08 each. PropertyRadar is also the wrong tool for mapping a CRE owner's national portfolio at Reonomy's scale, and it does not sell bulk data licenses the way ATTOM does.

Where BatchData Wins: Published Accuracy at API Volume

BatchData publishes a 76% right-party contact rate and describes it as roughly 3x the industry average (BatchData skip tracing). The figure is vendor-reported and has not been independently audited, and it is still the only named RPC number in this category, which makes it the reference point competing accuracy claims get measured against (skip tracing comparison).

The data underneath covers 155 million properties with 700+ attributes per record, assembled from 12 primary sources and 3,200+ supporting sources and refreshed daily (API competitive advantage). Cross-verification at that width is what BatchData credits for retiring disconnected numbers faster than a single-source provider can (phone validation methods).

Published subscriptions start at Growth, $1,000 a month for 100,000 property-data records, and skip-tracing plans run from $2,000 a month for 100,000 records to $20,000 a month for 3,000,000 (BatchData pricing). Pay-per-match rates land around $0.07 to $0.18 per matched record by volume (skip tracing comparison). Delivery covers a REST API plus S3, Snowflake, and Databricks, which is why proptech teams embedding skip tracing as a feature end up here (property data API demo).

That floor is the constraint for anyone under roughly 25,000 records a month, since $1,000 buys 100,000 records whether or not they get used, and checkout routes through a sales conversation and not a card form. BatchSkipTracing was consolidated into BatchData on August 15, 2025, so older reviews naming the standalone product describe the same platform (BatchData FAQ).

How Reonomy Wins CRE LLC Piercing

Reonomy has been an Altus Group business since a $201.5M acquisition that closed in November 2021 (Altus acquires Reonomy). Its entity resolution addresses the LLC-piercing problem no residential skip-trace tool touches at commercial scale, and it holds this slot over larger residential databases for that reason.

The 54M+ commercial dataset and the entity problem it solves

Public records list the legal owner, and in commercial real estate that owner is usually an LLC or a holding company with no human name attached. Reonomy unwinds that structure for 54M+ U.S. commercial properties across 3,100+ counties and 385 metropolitan statistical areas, surfacing phone, email, and mailing contacts for the people connected to the entity (Reonomy web application).

Machine-learning piercing of shell entities

Reonomy's entity resolution runs proprietary machine learning across billions of contact records to connect an LLC to the people behind it, then traces ownership chains across related entities and maps the properties tied to the same person (Reonomy overview). The dataset supporting that layer includes 68M+ property transactions, 5.2M+ companies, and 30M+ owner and contact records drawn from public and private sources.

Portfolio-level visibility

One owner's full portfolio is visible from a single property card, so a broker prospecting a $20M asset can see what else that owner controls and pitch the whole relationship. Mapping every property a CRE owner holds nationally is what separates Reonomy from a listings database, and it is why commercial service providers use it for target-list building.

Pricing and procurement

Reonomy lists $500 per user per month, or $400 on annual billing, with every plan including ownership records, entity resolution, and the full 54M+ property database (Reonomy web application). That band is out of reach for a wholesaler running 5,000-record lists, and trivial against a single commercial commission.

Who Reonomy is built for, and who it isn't

Reonomy is built for commercial brokers working off-market, CRE and private-equity acquisitions teams, lenders qualifying borrowers, and service providers such as roofing or solar contractors who need the owner and not the property manager. It is the wrong tool for residential skip tracing, because the database holds commercial parcels, the $400-per-user price assumes commercial commissions, and the workflow starts from an entity, not a mailing address.

How CoStar Wins Institutional CRE Owner Identity at Scale

CoStar is the institutional CRE research platform, and owner identity is one layer inside it, sitting next to the comps, lease analytics, and tenant records capital-markets teams already license. The way to think about CoStar here is as owner data that arrives with a research subscription the firm was buying anyway.

In the United States, CoStar reports 5.3M+ sale comps, 15.2M+ lease comps, and 8.2M+ tenant profiles, the depth an acquisitions analyst needs on the same screen as the ownership record (CRE professionals). CoStar does not price owner data as a standalone skip-tracing product, so a firm already licensing it for research gets ownership inside one workflow and one procurement cycle.

CoStar publishes no rate card, and Vendr's aggregated transaction data puts negotiated contracts between roughly $5,400 and $22,100 a year, with a median near $15,400 (CoStar contract data). That is a different order of spend from a $119 monthly subscription, and the procurement cycle alone disqualifies CoStar for a wholesaler who needs 5,000 owners contacted this week.

CoStar is the answer when an institutional CRE firm, capital-markets desk, large commercial brokerage, or REIT acquisitions team needs owner identity inside the research subscription it already runs. CoStar isn't the answer when the job is high-volume residential owner contact at SMB pricing, or CRE entity resolution as a point-of-need tool without the broader commitment.

Where Cotality and ATTOM Challenge

Cotality assigns a persistent ID to every parcel and ATTOM licenses bulk attributes by the row, so both sit next to the owner-contact job without taking it. Neither takes any of the three jobs above, and each is the right answer in a narrower lane.

Cotality and the CLIP identifier

Cotality (formerly CoreLogic, rebranded March 2025) resolves identity at the property level and not the human-owner level (Cotality rebrand). Its CLIP identifier is a persistent property ID that ties deeds, permits, listings, and geospatial records to the same parcel, with 157M+ CLIP IDs issued and a 99.2% match rate against customer portfolios (CLIP product page). A separate Property Intelligence product reports data on 99.99% of the country's 152 million parcels, a coverage figure and not the CLIP matching statistic (Property Intelligence).

Cotality is the answer for a mortgage lender or insurer doing property-identity resolution inside a risk or valuation workflow. It is the wrong answer for an SMB wholesaler working an absentee-owner mail list, because the CLIP solves a property-identity problem and never returns a phone number.

ATTOM and B2B enrichment depth

ATTOM sells the raw material for an owner-identity workflow, covering 158M+ properties in more than 3,000 counties with 9,000+ attributes and 70B+ rows of transaction-level data (ATTOM property data). Delivery runs through Snowflake, Databricks, and an MCP endpoint alongside the API, which suits a data team that wants to build the interface itself (ATTOM delivery). ATTOM publishes no entry price for API access, offering a free developer key and a sales conversation past that (ATTOM developer platform).

ATTOM acquired the ResiShares platform and technology on January 20, 2026, adding analytics while the buyer profile stayed the same (ATTOM acquires ResiShares). Property Navigator, its finished UI, is $499 a year for one seat with 200 reports and 2,000 list exports a month, which serves a light user and not a campaign operation (Property Navigator pricing).

Use-Case Matrix: Pick by Buyer Type

PropStream is the bundled SMB generalist, with property data, owner lookups, skip tracing, MLS comps, and a rehab calculator in one subscription at $99, $199, or $699 a month (PropStream pricing). Skip tracing costs $0.12 per contact on Essentials and comes included on Pro and Elite through PropStream Connect, with extra contacts at $0.10.

Connect replaced the old Lead Automator add-on and costs $30 a month on Essentials, and PropStream's July 2025 acquisition of BatchLeads and BatchDialer put dialing and lead generation inside the platform (PropStream acquires BatchLeads). It stays the runner-up for owner identity because it publishes no accuracy figure, and its per-contact trace pricing costs more than PropertyRadar's included allowance at low volume.

Other Property Data Platforms

Picking the Right Platform for Your Job

Pick PropertyRadar if you work residential owner lists in the hundreds or low thousands each month and want contacts, mail, dialing, and monitoring billed together. The included allowance and $0.04 to $0.08 overage beat pay-per-trace pricing at that volume, and the tradeoff is a platform with no published match rate.

BatchData is the answer for teams enriching 100,000 records or more each month, or embedding skip tracing inside a product, where the 76% RPC claim is the number a procurement review will ask about. The $1,000 monthly floor makes it the wrong first subscription for anyone tracing a few hundred owners.

Choose Reonomy when the job depends on reaching the human behind a commercial LLC. The 54M+ property dataset and portfolio view turn a single lookup into a relationship map, and $400 per user per month is the price of admission.

CoStar fits the institutional buyer who already carries, or needs, the research and capital-markets subscription, since owner identity comes inside that workflow. Cotality suits a mortgage or insurance data team that needs parcel-level identity resolution as infrastructure, where the CLIP is the right primitive for the job.

ATTOM is the answer for a team building its own owner-identity workflow on bulk data, since 9,000+ attributes and cloud delivery serve data engineers better than they serve operators. Plan allowances, tier floors, and per-seat prices in this category all moved within the past year, so confirm the current numbers with each vendor and treat any published accuracy percentage as a vendor claim until an independent test backs it.
