Real estate farming in Baltimore starts with the street you just sold on.
Baltimore values are compounding quietly — up 5.2% between the last two ACS five-year estimates. Steady markets reward the agent whose name is already in the kitchen drawer. 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
599,214 mailable homes carry a Baltimore address across 685 Census block groups. We measured it against our address map: a 100-home farm around a typical Baltimore address spans about 230 feet — that's one walkable pocket of streets. Dense blocks like Baltimore'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 Baltimore home is valued at $255,700, up 5.2% across the last two ACS five-year estimates — the kind of steady equity build that turns into a move-up listing when the timing lands. One listing at that median is roughly $6,400 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
50.9% owner-occupancy means a working mix: owner-occupants who will list someday, plus investor-owned homes that trade more often and on shorter notice. With a median build year of 1951, these are long-held streets — when homes like this list, it's often after decades in one set of hands, and the seller calls whoever has been showing up in the mailbox.
One closing. One hundred mailboxes. One name they remember.

Real estate farming in Baltimore, answered with numbers.
599,214 mailable residential addresses carry a Baltimore mailing address in the Quillus map, across 685 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 Baltimore home is valued at $255,700 (up 5.2% between the two most recent ACS five-year estimates). At a 2.5% commission side, one median listing is roughly $6,400 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 Baltimore addresses against our map, the 100 nearest homes around a typical address sit within about 230 feet (71 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 Baltimore 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 Baltimore 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 Baltimore 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 Baltimore listing is on a street you already know.
