The stacking model is a practical system for agents who refuse to be out-marketed by platforms with billion-dollar budgets, Zac Kennedy writes.

In Part 1, I argued that the Rocket-Redfin consolidation and The Real Brokerage’s acquisition of REMAX are a preview of the competitive environment every agent will be operating in for the next decade.

Rocket’s 97 percent client retention rate in 2025 is not a coincidence. It is what happens when a company builds an ecosystem so consistently present that clients never feel the need to look elsewhere. Every touchpoint feeds the next. 

The flywheel spins faster with every transaction.

The question Part 1 left on the table: how does an individual agent build their own version of that?

The answer is not to scale. It is to stack.

Why scaling fails and stacking works

The real estate industry is obsessed with scale. More calls, more mailers, more ads. Volume does not solve the problem. 

Scaling a weak marketing strategy just produces more of the same weak results at a higher cost.

The agents who are genuinely difficult to compete with are not doing more. They are layering multiple types of marketing into single, high-leverage campaigns that work across every channel at once.

Every agent has access to five types of marketing:

  • Traditional
  • Relationship
  • Content
  • Digital
  • Direct

Most agents use one or two in isolation. A stacked agent deploys all five in a single campaign. 

The stacking score measures how efficiently a campaign is built: one point for each marketing type present. A five means all five are active. Anything below that shows you exactly where the gaps are.

The 4 content pillars

Every campaign should also draw from four content pillars.

  • Listings: Your active inventory and market activity. Your most direct signal that you are working.
  • Community: What is happening in the neighborhoods you serve. This positions you as someone who actually lives in this market, not just someone who sells in it.
  • Expertise: Your analysis of market conditions translated into what it means for a buyer or seller in a specific zip code. This is where you earn the right to be trusted.
  • Branding: The most underused pillar and the most powerful.

Real branding is not logo and colors. It is positioning yourself as the agent who understands that real estate transactions are almost never about real estate. They are about what is happening in someone’s life that requires a move: death, divorce, diapers, diamonds, diplomas. 

The agents who speak directly to these life events are the ones whose names surface first when those moments arrive.

2 stacked campaigns, scored

Campaign 1: The neighbors-only open house (Score: 5/5)

A new agent with a small database was hosting an open house on a colleague’s listing. Rather than simply showing up and hoping for walk-ins, she built a campaign around it.

She mailed an 8.5 x 11 letter to homeowners in the surrounding neighborhood, inviting them to a neighbors-only open house the Sunday before the public showing. The letter included her price analysis for the area and a QR code linking to the online listing. 

Six parties attended the private hour. Several brought family members considering a move to the area, and all six signed in with full contact information. 

A new agent with a small database walked away with a list of warm, qualified leads in the exact neighborhood she wants to build her business in.

The stacking score:

  • The physical letter is Traditional.
  • The neighborhood targeting is Relationship.
  • The letter itself is Content.
  • The QR code is Digital.
  • The deliberate outbound mail to a specific list is Direct

Five for five. 

All four content pillars hit: listing, community, expertise demonstrated at the open house, and a branding statement by targeting prospects in a specific area who have specific desires.

Campaign 2: The consistent email (Score: 5/5)

If the open house campaign is a sprint, this is the engine that keeps everything running between events.

A consistent, well-structured email sent to your database on a regular cadence is one of the most underrated tools in real estate marketing. No print vendor, no ad spend. It goes directly to people who already know you and keeps you present between transactions. Four sections, one for each content pillar. 

The first features active listings or recent sales. The second covers something happening in the community. The third is your read on market conditions or a question you keep getting asked. The fourth is your branding section — where you speak directly to the life events that drive real estate decisions. Death, divorce, diapers, diamonds, diplomas. 

Write to those moments consistently, and you become the agent people call before they arrive.

The stacking score:

  • Traditional channel
  • Relationship database
  • Content across four sections
  • Digital through links and calls to action
  • Direct because you choose exactly who receives it

Five for five.

This is your retention mechanism. It is your version of the 97 percent.

The agent flywheel

The stacking model sits in the middle layer of a three-part business structure that every agent needs to build deliberately. Operations is the foundation; your brokerage’s job is to support this so completely that you never have to think about the back office.

Marketing is what you build on top of that. The goal of every stacked campaign is the same: Create the conditions for a conversation. Sales is where the flywheel pays off. 

  • A conversation becomes an appointment.
  • An appointment becomes a client.
  • A client becomes a contract.
  • A contract becomes a closing.
  • A closing funds better operations, a stronger database and more marketing capacity. 

The flywheel spins faster with every revolution.

The platforms being built at the national level are spending billions to construct this at scale. You do not need a billion dollars. You need five marketing types, four content pillars and the discipline to stack them consistently.

Stop worrying about being the biggest agent in the room. Just make sure you are not the slowest one.
