About This Property
Pacific Heights Estate — San Francisco City Views
Situated on nearly half an acre in the heart of San Francisco's Pacific Heights, this four-bedroom estate commands panoramic views of the city skyline, the Bay, and the Golden Gate from every principal room. Floor-to-ceiling glass runs the length of the main living level, dissolving the boundary between interior and the city spread below.
The chef's kitchen features Calacatta marble countertops, professional-grade appliances, and an oversized island built for the way people actually live. The primary suite occupies its own wing — spa bath, walk-in dressing room, and a private terrace where the city lights replace the need for any other view.
Three additional bedrooms, a detached office studio, radiant floor heating throughout, and mature landscaped grounds complete a property that delivers both the scale of a private estate and the immediacy of San Francisco at its most walkable. No HOA. Walk Score 96. Move-in ready.

The Standard Ledger Company · Real Estate Ledger Profile
Your listing. Not Zillow's.
Your leads. Your edges. Your record.
Zillow owns your listing. They take the inquiry. They sell your buyer back to you as a Premier Agent subscription — you pay to receive your own lead. The edges go to Zillow, not to your entity. When someone asks ChatGPT "what properties are available in Napa under $1.5M" the answer cites Zillow. The Ledger Profile changes every one of those facts. Your listing, your edges, your lead capture — direct to you. Flat rate to the Standard Ledger Company. No cut. No middleman on your buyer.
Zillow · Realtor.com · Trulia
✕They own your listing — data lives on their servers
✕Your buyer inquiry goes to Zillow first, not to you
✕Premier Agent — you pay to receive your own lead back
✕AI cites Zillow — edges go to the platform, never your entity
✕No provenance — AI cannot trace claims to a verified source
✕No graph edges — listing isolated from neighborhood and city entities
✕Listing removed when payment stops — no permanent record
Traditional Listing Page · MLS Only
⚠Keyword-optimized — AI reasons about entities, not keywords
⚠No structured schema — AI cannot resolve listing with confidence
⚠No edges to school district, neighborhood, city entity
⚠No provenance — no timestamped source chain
⚠Lead capture routes through brokerage platform — not direct
⚠Hallucination risk high — AI fills gaps with inference
⚠Sold listings disappear — no historical graph value
Ledger Profile · Standard Ledger Co.
✓Your listing, your URL, your permanent provenanced record
✓Lead capture goes directly to your agent — no platform cut
✓Flat rate to SLC — $12/year · You keep every inquiry
✓AI cites your entity — not Zillow — as the authoritative source
✓14 active edges — school district, city, county, price range, MLS
✓When listing sells — edges stay in graph. Sold record compounds forever.
✓Hallucination risk near zero — boundary declarations active
Semantic Edge Map
14 active edges. Every one a path to discovery.
A buyer asking AI "3-bedroom under $1.5M in San Francisco County near good schools" finds this listing because you declared the school district, county, price range, and property type as active edges in the graph. Each edge is a traversable path. The denser the semantic connections between your listing and the world around it — the more discoverable you become.
City of Napa
Anyone researching Napa real estate traverses from the city entity to your listing. The city profile links to every declared property.
San Francisco County
County-level queries — "luxury estates in San Francisco County" — traverse this edge directly to your property record.
San Francisco USD School District
A buyer asking "good schools near Napa" finds this listing because you declared the school district as an active edge.
Price Range · $1–$1.5M
Price band edges mean your listing appears in queries filtered by budget — without the buyer ever mentioning your address.
Napa Valley Wine Country
Cultural context edges connect your listing to wine country lifestyle queries — buyers researching the region before they ever search for a property.
Agent Entity · Sarah Mitchell
Every listing builds the agent's personal authority in the graph. After 20 listings, Sarah is the authoritative entity for Napa Valley luxury real estate.
When the listing sells — the record does not disappear. The sold property becomes a historical data point in the graph. AI systems reasoning about comparable sales, neighborhood price trajectories, and San Francisco County market conditions include this record in their reasoning chain permanently. The agent's authority compounds. The neighborhood's data density increases. The graph grows richer around every sold listing. This is the infrastructure that no platform builds for you. We build it with you.
