Real estate farming in Walnut Creek starts with the street you just sold on.
Walnut Creek is a stable market — which means listings go to the agent the street already knows, not the one with the biggest ad budget. Quillus mails the 100 homes nearest every closing, listing, or open house — within 24 hours, each card tracked to the house that scanned it.

The farm math
70,867 mailable homes carry a Walnut Creek address across 75 Census block groups. We measured it against our address map: a 100-home farm around a typical Walnut Creek address spans about 410 feet — that's one walkable pocket of streets. Dense blocks like Walnut Creek's are where farming compounds fastest: one just-sold card is seen by neighbors who actually talk to each other across the fence.
The equity picture
The median Walnut Creek home is valued at $1,101,900, holding steady across recent ACS estimates — in a flat market, the listing follows the relationship, and the relationship follows consistent presence. One listing at that median is roughly $27,500 in gross commission at a 2.5% side — a 100-card farm touch costs about what you'd spend on a single boosted social post.
The listing supply
65.3% of occupied Walnut Creek homes are owner-occupied — nearly every mailbox in a farm here belongs to a potential future seller, not a property manager. The median Walnut Creek home dates to 1974 — established streets where ownership runs long and a listing event next door is the strongest prompt an owner ever gets.
One closing. One hundred mailboxes. One name they remember.

Real estate farming in Walnut Creek, answered with numbers.
70,867 mailable residential addresses carry a Walnut Creek mailing address in the Quillus map, across 75 Census block groups. A productive farm is a slice of that — Quillus builds farms from the 100 homes physically nearest any address you pick (a closing, a listing, your own block), so every card lands where your name already means something.
The median Walnut Creek home is valued at $1,101,900 (up 2.7% between the two most recent ACS five-year estimates). At a 2.5% commission side, one median listing is roughly $27,500 in gross commission — which is why a farm that produces even one extra listing a year pays for its postcards many times over.
Tighter than you'd think. Sampling real Walnut Creek addresses against our map, the 100 nearest homes around a typical address sit within about 410 feet (125 meters). That's a true neighborhood farm — the same streets, the same sight lines — not a ZIP-code mailing list. That distance is the farm's proximity radius — the working unit of proximity mail marketing.
Enter the sold property's address. Quillus finds the 100 nearest Walnut Creek homes, builds each neighbor a card — your branding, the sale announcement, and a satellite view of their own home — and has them in the mail stream within 24 hours, while the sign is still in the yard. Every card carries its own QR code, so you see exactly which neighbors scanned.
Yes — by construction. Quillus targets on geography and housing-market signals only: distance from your address, home counts, values, housing stock. It never selects recipients by race, national origin, religion, sex, familial status, disability, or any other protected characteristic, and the Walnut Creek figures on this page are aggregate housing-market statistics from the U.S. Census Bureau — not data about who lives in any home.
Two sources: the Quillus address map (155M+ geo-located U.S. addresses — the Walnut Creek home counts and farm-radius figures are measured from it directly) and the U.S. Census Bureau's American Community Survey 5-year estimates (2024 vintage) for home values and occupancy. Figures are city-level aggregates, refreshed when new ACS data ships.
Your next Walnut Creek listing is on a street you already know.
