The challenge

Maria Bennett was a solo realtor working a Tampa neighborhood farm of 600 single-family homes. Her business model required 8-10 listings per year to clear her income target, and her existing pipeline came almost entirely from referrals and her sphere: typical for a 6-year-experience agent in a stable market. The neighborhood she'd been farming had a mid-tier listing-to-sale velocity, with roughly 4-6 homes listing per month. She'd been drip-mailing the farm with monthly market-update postcards, but had never directly leveraged a just-listed event to drive buyer leads or listing conversations.

Her existing farm marketing was a single monthly newsletter postcard at roughly $0.65/piece, generating maybe 2-3 inquiries per quarter: most of which went nowhere. She suspected her newsletter postcards had become wallpaper to the farm. The just-listed event was a different opportunity: a fresh, time-relevant reason to be in mailboxes, surfacing both buyers and adjacent neighbors who might be considering a sale.

Real-estate just-listed farms are notoriously low-response (0.5-1.5% range), and the math only clears for agents who treat each campaign as a long-term brand-deposit rather than a short-term lead generator. Maria had been skeptical of the channel until a coaching call surfaced the actual lifetime value math: one converted listing in this neighborhood (at $385K average sale price, 3% gross commission, 60% split = $11,550 net) covers the campaign cost roughly 35x over.

The PostKnock approach

Playbook used: Custom just-listed farming sequence

We built a custom just-listed farming sequence in PostKnock with a 3-postcard cadence triggered off a single just-listed event in the farm. Listing event: a 4-bedroom on Westshore Blvd hit MLS at $419K. The 600-home farm received the campaign on a 14-day rolling sequence: just-listed (Day 1), open-house invite (Day 7), and just-sold/under-contract follow-up (Day 28, sent regardless of outcome to surface market activity).

Wave 1 (just-listed) was a 6x9 postcard with the property photo, key details ("4BR, 2.5BA, $419,000, listed by your neighborhood specialist"), and a dual CTA: a QR code linking to a buyer-targeted listing page with photos and instant tour scheduling, and a separate phone number for sellers asking "what's my home worth?" Wave 2 (open-house invite) dropped a week before the open house with a "come see for yourself" angle. Wave 3 (just-sold/under-contract) closed the loop with social proof. "Westshore prices are real, here's what just sold."

There was no phone follow-up; for a solo agent, cold-calling 600 households is impractical and reads as intrusive. The campaign relied entirely on inbound: QR scans, direct callbacks, and the longer-arc effect of consistent presence in the farm. Total: 1,800 pieces over 4 weeks. Maria's per-piece cost ran $0.66 because she elected the agent-branded high-gloss option: defensible in real estate where the postcard IS part of the brand.

Campaign timeline

Day 1
Westshore listing hits MLS. Wave 1 (just-listed) drops to 600-home farm.
Day 4-6
Inbound buyer inquiries: 3 QR scans → 2 tour requests.
Day 7
Wave 2 (open-house invite) drops.
Day 14
Open house: 11 walk-throughs from the farm. 1 immediate offer (different agent, but the activity drove farm awareness).
Day 21
Property under contract.
Day 28
Wave 3 (just-sold/under-contract) drops. 2 "what's our home worth?" callbacks within 72 hours.

on $1,485 cost

Five direct responses across the 600-household farm: 4 buyer-side inquiries (2 of which became tour requests, 1 of which became an active buyer Maria represented on a different property within 60 days) and 2 listing-side callbacks ('what's our home worth?'). Total: ~0.8% response rate, in the middle of the 0.5-1.5% real-estate just-listed range. Of the 2 listing conversations, 1 progressed to a signed listing agreement on a $385K Westshore home that closed in Q2.

Campaign cost ran $1,485: $1,188 in postcards (1,800 at $0.66, including agent-branded gloss), and $297 in PostKnock Pro for 3 months. Net commission on the converted listing: $11,550 (3% gross, 60% net split). First-attributable ROI: 7.8x on a single listing, but the honest math credits the listing only partially to the campaign (Maria had farmed the neighborhood for 18 months prior; the just-listed sequence was a catalyst, not the sole cause). Conservative attribution at 30% credit gives a real ROI of 2.3x. The campaign also surfaced 4 buyer leads worth roughly $1,200 in expected commission tail, bringing combined attributed value closer to $4,665 and ROI to 3.4x. The bigger story is brand deposit. The farm is now actively engaged, and Maria's next listing campaign will start from a warmer audience.

“I'd been told just-listed mailers were a brand investment, not a lead generator. The brand investment is real, but the listing call I got 30 days later was very much a lead. Both can be true.”

What we’d do differently

  • Honest attribution matters in this category. We'd recommend agents avoid claiming "the postcard caused the listing": the truth is the postcard was one of 8-10 touches, and crediting it appropriately keeps your channel-mix honest.
  • The just-sold/under-contract Wave 3 was the highest-impact piece for surfacing seller-side conversations. Buyers respond to Wave 1; sellers respond to Wave 3 (proof the market is moving in their pocket).
  • Agent-branded gloss-finish at $0.66/piece vs. standard at $0.60 added $108 to the campaign cost. We'd default to standard for the buyer-side waves and reserve gloss for the seller-targeted Wave 3: the only piece where the brand affordance materially changes outcomes.
