Real Estate Directory: Purpose and Scope

The National Property Services Authority directory catalogs licensed, qualified, and nationally scoped real estate service providers operating across the United States. This page describes the organizational structure of that directory, the criteria applied to listings, how records are maintained, and which categories fall outside the directory's defined scope. Professionals, researchers, and service seekers using this resource should understand these boundaries before drawing conclusions from any individual listing or category.

The real estate services sector in the United States encompasses more than 3 million active licensed agents and brokers, alongside a broader ecosystem of appraisers, inspectors, property managers, title professionals, and transaction coordinators — each governed by distinct licensing frameworks administered at the state level, with federal oversight applied to specific transaction types. This directory organizes that landscape by professional category, credential type, and service scope to support accurate navigation rather than promotional discovery. For an orientation to how the directory is structured for navigation, see the How to Use This Property Services Resource page.

How to use this resource

The directory functions as a structured reference instrument, not a lead-generation platform or ranked listing service. Entries are organized by professional category and geographic scope — not by commercial relationship or advertising arrangement. No listing receives elevated placement based on payment.

Real estate service providers appear under one of four primary classification tracks:

1. Transaction Professionals — licensed real estate agents, brokers, and dual agents operating under state licensing authorities such as state real estate commissions recognized by the Association of Real Estate License Law Officials (ARELLO).
2. Valuation Professionals — state-certified and state-licensed appraisers credentialed under standards enforced by The Appraisal Foundation's Appraiser Qualifications Board (AQB), as established by the Financial Institutions Reform, Recovery, and Enforcement Act of 1989 (FIRREA).
3. Property Condition Professionals — home and commercial property inspectors operating under state-level licensing requirements, with standards benchmarked against the American Society of Home Inspectors (ASHI) and the International Association of Certified Home Inspectors (InterNACHI).
4. Property Management Professionals — residential and commercial property managers, with licensing requirements varying by state under real estate commission authority and, in federally assisted housing contexts, subject to oversight by the U.S. Department of Housing and Urban Development (HUD).

Each track carries distinct credentialing requirements. A licensed broker and a certified general appraiser, for example, hold credentials issued under different statutory authorities and cannot be treated as interchangeable categories within the directory. Users researching a specific service type should navigate to the applicable classification track rather than relying on general keyword search to distinguish credential levels.

Standards for inclusion

Listings in this directory are subject to a 3-stage qualification process applied before publication.

Stage 1 — License or Credential Verification. The listed entity must hold an active, verifiable license or credential in the professional category under which it is listed. For transaction professionals, this means an active license issued by a state real estate commission. For appraisers, this requires an active credential appearing on a state appraiser regulatory agency's roster, consistent with Title XI of FIRREA and the Appraisal Subcommittee's National Registry. Expired, suspended, or revoked credentials disqualify an entry.

Stage 2 — Scope Validation. Geographic service claims are reviewed for consistency with operational capacity. A provider listed as nationally scoped must demonstrate service reach extending beyond a single metropolitan area. Regional providers serving fewer than 3 states are classified under state or regional scope designations rather than national listings, consistent with the classification thresholds applied across the Property Services Listings category.

Stage 3 — Categorical Placement. Each entry is assigned to the narrowest applicable professional category. A brokerage offering both transaction and property management services receives separate entries per category rather than a single consolidated listing, unless the two service lines operate under a single unified license. Listings that cannot be placed within a defined category are held for reclassification rather than published under an undifferentiated heading.

How the directory is maintained

Directory records are subject to periodic editorial review on a rolling basis. License status, credential standing, and scope claims are rechecked against primary source registries — including state real estate commission databases, the Appraisal Subcommittee National Registry, and the U.S. Bureau of Labor Statistics Standard Occupational Classification system for professional category benchmarking.

Listings flagged during review fall into one of three statuses:

• Active — credential verified, scope confirmed, categorical placement current.
• Pending Review — one or more data points require re-verification against primary source; the listing remains visible but is marked pending.
• Removed — credential lapsed, revoked, or suspended, or the provider has ceased operations in the listed category. Removed listings are not archived in publicly visible records.

No listing is restored to Active status based on self-reported updates alone. Reinstatement requires independent verification against the applicable licensing authority's public registry. This process distinguishes the directory from general commercial registries, which typically accept self-submitted data without cross-referencing issuing authority records.

What the directory does not cover

The directory's scope is bounded by the professional categories and credentialing standards described above. The following categories fall outside those boundaries by design and are not represented in any listing:

• Unlicensed transaction facilitators — entities or individuals marketing real estate services without a state-issued license, regardless of business registration status.
• Real estate investors and iBuyers — companies purchasing or selling property as a principal are not service providers in the professional service sense and are excluded from all listing categories.
• Advocacy organizations and trade associations — bodies such as the National Association of Realtors (NAR) represent industry members but do not themselves deliver licensed services to consumers; they do not appear as directory listings.
• Mortgage origination and lending — loan officers, mortgage brokers, and lenders operate under separate federal licensing frameworks administered through the Nationwide Multistate Licensing System (NMLS) and fall outside the property services classification structure used here.
• Legal services — real estate attorneys providing transactional or litigation services are governed by state bar authorities, not real estate licensing boards, and are classified under legal services verticals rather than property services.
• Subsidiary brands without independent credentials — a subsidiary operating under a parent company's license is consolidated under the parent listing unless the subsidiary holds independent credentials issued in its own name.
