Luxury Property Showcase with Virtual Tours & Private Buyer Portal

Problem and target customer

Why this exists

Customer problem

Luxury agents need to market a property broadly while controlling sensitive materials and coordinating serious buyer follow-up outside scattered links, files, and calendars.

Who pays

Boutique luxury brokerages and listing agents marketing high-value residential properties to manually qualified buyers.

Business model

Monthly brokerage subscription or per-listing digital marketing package

Editorial note

The private portal is a disclosure boundary, not a prestige decoration. Public visitors should learn enough to request access, while approved buyers receive revocable property-specific material.

Investment analysis must remain a transparent worksheet. Saving assumptions can support a buyer's comparison, but the product should not convert those inputs into a recommendation or return promise.

Product goal

Who it serves and what it must change

Target user: A luxury listing agent or boutique brokerage serving qualified buyers for high-value properties.
Problem: Public listing pages cannot safely present all private materials, while ad hoc file sharing and scheduling make buyer qualification and showing follow-up difficult to track.
Measurable outcome: An agent can grant limited portal access, and an approved buyer can view the tour and property materials, adjust disclosed analysis inputs, and submit a showing request with a traceable status.

Core entity outline

Entities and business rules

Property

Stores public facts, media references, tour URL, and listing status.

Fields: title, address_display, price, facts, listing_status, tour_url
Relations: Has PropertyDocuments, Receives AccessRequests

BuyerProfile

Stores verified contact information, representation status, and privacy consent.

Fields: user_id, name, email_verified_at, representation_status, consent_at
Relations: Has AccessRequests, Has SavedScenarios

AccessRequest

Records manual review, expiry, and reason for one property-buyer pair.

Fields: property_id, buyer_id, status, reviewed_by, reviewed_at, expires_at, reason
Relations: Belongs to Property, Belongs to BuyerProfile

PropertyDocument

References a private file and its disclosure label.

Fields: property_id, storage_key, label, visibility, version
Relations: Belongs to Property

InvestmentScenario

Stores buyer-entered assumptions and deterministic calculated outputs.

Fields: property_id, buyer_id, purchase_price, down_payment, interest_rate, rent, expenses, saved_at
Relations: Belongs to BuyerProfile, References Property

ShowingRequest

Tracks requested time windows and the agent's confirmed or alternative time.

Fields: property_id, buyer_id, preferred_windows, status, confirmed_at, agent_note
Relations: Belongs to Property, Belongs to BuyerProfile

Business rules

Private documents require granted, unexpired access for the same property.
Virtual-tour URLs marked private are issued only inside an authorized property room.
Investment outputs display formulas, assumptions, and a non-advice notice.
A buyer may have one open showing request per property.
Only an agent can grant access or confirm a showing.

Architecture and data flow

Components, integrations, and controls

Public listing site

Serves property discovery, media, facts, and the access call to action.

Buyer portal

Shows authorized materials, saved notes, scenarios, and showing status.

Agent desk

Reviews access requests and coordinates showings.

Access API

Applies property-specific authorization, expiry, document, and scheduling rules.

Postgres and private storage

Store listing records, access decisions, buyer inputs, and gated files.

Integrations

Required: an embeddable virtual-tour provider URL supplied by the listing agent.
Required: private object storage for gated property documents.
Optional: calendar and transactional email after an agent confirms a showing.
Optional automation may relay confirmed appointments but cannot approve buyers.

Data flow

Public property content loads without buyer identity or private file references.
Verified registration creates an AccessRequest for agent review.
Granted access enables short-lived document URLs and the configured tour embed.
The worksheet calculates from buyer-entered inputs in a deterministic service and saves optional scenarios.
Showing requests remain pending until an agent confirms or proposes an alternative.

Failure handling

If a tour provider is unavailable, show property media and an agent contact path without claiming the tour loaded.
If access expires mid-session, preserve public navigation and require a new request for private material.
If calendar handoff fails, keep the confirmed showing visible and alert the agent to retry.

Security

Enforce access by buyer, property, status, and expiry on every private request.
Use expiring signed document URLs and avoid exposing storage keys.
Encrypt sensitive buyer profile fields and restrict agent exports.
Log access grants, revocations, and document retrievals.

Rate limits

Throttle registration and access requests by email and IP.
Limit signed document URL issuance per authorized buyer.
Cap showing-request changes and agent notification retries.

Deliverables and acceptance

Definition of done for the MVP

Deliverables

Public property showcase
Buyer registration and manual access desk
Private property room and documents
Investment worksheet
Showing request state machine
Authorization and expiry tests

Acceptance criteria

A buyer granted access to one property cannot retrieve another property's private material.
Expired access invalidates new signed document URLs immediately.
Every investment output can be reproduced from the displayed assumptions and formula.
A failed tour embed leaves a usable gallery and contact action.
A showing remains pending until an agent explicitly confirms a time.

Recommended stack

Enough technology for the first version

Web experience

Next.js and TypeScript

Supports image-rich public pages and authenticated buyer and agent routes.

Data and authorization

Postgres with row-level policies

Enforces property-specific grants, expiry, showing states, and saved assumptions.

Private media

S3-compatible object storage and CDN

Protects disclosure documents while serving optimized listing imagery.

Tour integration

Provider iframe adapter

Embeds an agent-supplied tour URL with allowlisting, status monitoring, and fallback content.

Why this is sufficient

The core challenge is selective disclosure and traceable buyer coordination, so access control and graceful third-party tour failure matter more than custom 3D technology.
