Real estate is, and always will be, a relationship-driven business. Your database is packed with past vendors, buyers and appraisal leads, as well as people who clicked, enquired or transacted years ago, yet most agents are only speaking to a fraction of them. But each of these people trusts you and could be a solid way to generate appraisals, listings, referrals and repeat business.
It’s all down to understanding your sphere of influence.
Sphere of influence in real estate matters. Sometimes called a real estate SOI, it’s the network of people who already have some connection to your agents or brand.
Managed properly, your SOI is a huge asset. Managed badly, your influence fades, and your database becomes thousands of ageing records sitting untouched in your CRM.
For leaders of enterprise real estate organisations, the opportunity is bigger than helping individual agents remember to follow up. It is about building a repeatable system that keeps every office visible, gives agents useful reasons to call and protects the value of the database you have already paid to build.
We’ll explore how to do just that.

What is a Sphere of Influence in Real Estate?
SOI stands for sphere of influence. The SOI meaning in real estate is the network of people an agent or agency can reach through an existing relationship.
Think of your SOI as your very own VIP club. These are the folks who already know you, trust you and like you. This group isn’t just your immediate family and best friends (though they’re definitely included); it’s everyone you’ve ever interacted with.
It can include:
- Past vendors and buyers
- Current clients
- Landlords and investors
- Previous appraisal leads
- Open-home attendees
- Referrals
- Friends, family and former colleagues
- Local business and community contacts
- People who have enquired about a property or subscribed to updates
Some relationships will be strong. Others may amount to one enquiry made two years ago.
Both can hold future value.
The mistake is assuming that anyone who is not ready to transact now is irrelevant. Property decisions can take months or years. If your agents disappear between the first enquiry and the eventual decision, another brand gets the opportunity.
Build Consent Into Your SOI Strategy
Your sphere is a relationship network. It is not permission to contact everyone indiscriminately, even if they are your friends and family!
In Australia, the Spam Act 2003 applies to commercial electronic messages. As a general rule, these messages require consent, accurate sender information and a working unsubscribe facility.
In New Zealand, the Unsolicited Electronic Messages Act 2007 prohibits unsolicited commercial electronic messages with a New Zealand link. Businesses must have an appropriate form of consent, identify the sender accurately and provide a functional unsubscribe facility. New Zealand’s Department of Internal Affairs provides a useful business compliance overview.
Your systems and processes should record:
- How and when consent was obtained
- Which brand or organisation the person agreed to hear from
- Communication preferences
- Unsubscribe requests
- Suppressed contacts
- The source of imported data
Why Your Sphere of Influence Matters
Most agents and brokerages do not have a contact problem. They have a consistency problem. While new marketing approaches are existing to chase, the real contacts are likely waiting patiently to be contacted.
Your business spends money attracting leads through portals, advertising, content, events and prospecting. Then follow-up slows down. The database goes quiet. Marketing teams are pushed to generate more leads. Agents complain about lead quality. Acquisition spend rises while existing relationships are left untouched.
Statistics show that leads from your SOI are far more likely to convert than cold leads. According to a study by Buffini & Company, 82% of all real estate transactions come from referrals, repeat business, or personal contacts. This is in stark contrast to the much lower conversion rates seen with cold leads, where the average conversion rate is just 1% to 3%.
Better sphere of influence marketing helps you get more value from the contacts already in your systems before you pay to acquire another audience.
There’s another issue too: timing.
Storing data is not the same as using it. Property interests, previous transactions, campaign engagement, and appraisal activity are all rich insights, but ignore them and that relationship starts to decay.
According to a consumer panel reported by Inman, only around 17% of homeowners use the same agent again, with a forgotten name cited as one of the main reasons agents aren’t rehired. In other words, roughly 83% of agents lose the relationship after handing over the keys, largely because they go quiet once the deal is done.

Who Belongs in Your Sphere of Influence?
Your agents’ closest contacts are only the beginning. At the enterprise level, it helps to think about the sphere in four groups.
- Active relationships: Current vendors, buyers, landlords and tenants. Communication is already happening, but the future relationship still needs attention.
- Previous clients: They may transact again, own other property or know someone who needs an agent.
- Known prospects: Includes appraisal leads, property enquirers, open-home attendees and people who have requested market information. They have shown an interest and coild be moving towards getting in touch, or going cold.
- Wider personal and community contacts: Friends, relatives, tradespeople, local business owners, school contacts and sporting-club connections can all sit within an agent’s sphere.
These relationships require care and nurturing, alongside a proper lead generation strategy.
How to Nurture Your Sphere of Influence
Staying visible does not mean sending more emails to everyone. It means matching useful communication to the relationship and giving agents clear follow-up opportunities.
Use a system
Important relationship data should not live only in personal phones, inboxes or notebooks. You need to ensure that it’s in the open. Use your system to make it clear how each contact is connected. Sections like relationship type or freeform text will help you see relevant notes. This is essential to maintain knowledge that seems obvious now, but will be lost by the next big move in seven to ten years.

Keep data clean
Data hygiene is the process of keeping records accurate and usable, and this is really important for all your contacts. While you might have a great system now for all incoming leads, what about previous contacts and legacy leads? Not fixing these issues affects deliverability, reporting and agent confidence in the system.
Segment your contacts
Segmentation means dividing contacts into groups so they receive more relevant communication. Avoid creating dozens of segments your team cannot maintain. Start with differences that should genuinely change the message or follow-up — think past vendor, landlord, investor or first-home buyer, rather than a dozen micro-segments nobody has time to manage. Our guide on building a high-converting real estate agent mailing list walks through this in more detail.
Engaging with a SOI contact is all about trust. Your data should be able to tell you at a glance what their relationship with you is. This allows you to tailor messages. A past vendor is a very different check-in from a landlord or investor, and not everyone needs to see your first-home buyer content.
Use local information people can act on
Listings alone are rarely enough. Contacts may also value:
- Suburb-level market movements
- Guides for preparing a property for sale
- Practical buying information
- Local infrastructure and development updates
You can answer questions and focus on the issues that matter most to your audience. Consider:
- Seasonal Maintenance
- Upgrades and Additions that Up the Value of your Home
- Upgrades and Additions that Lower the Value of your Home
- When is a Good Time to Sell?
- When is a Bad Time to Sell?
- When Should I Repaint My House?
- Good vs Bad Landscaping
Our real estate newsletter templates are a good starting point if you need a format for this kind of content.
Combine automated communication with personal contact
Automated journeys are pre-planned sequences triggered by a contact’s stage, activity or data. For example, a potential vendor planning to sell within six months might receive:
- Recent results from the relevant suburb
- A local market update
- A later prompt to discuss timing or request an appraisal
If you need a starting point, these real estate email templates cover most of the common scenarios.
Use behaviour as a prompt, not a verdict
Behavioural data shows how a known contact interacts with your communications, such as viewing properties, clicking suburb reports or responding to a survey.
A contact repeatedly viewing similar properties may be researching a move. They may also be browsing on behalf of a relative or watching the market with no immediate plan. Present behavioural signals as reasons to investigate, not guaranteed intent. This is the idea behind lead scoring: gauging the temperature of your database rather than guessing.
Ask for a referral
“Do you know anyone looking to buy or sell?” puts all the work on the client, and the end result is you don’t get a referral.
It’s key to mention what you need. Are you working with buyers at a specific price point or helping local owners understand recent sales? Specific information is easier to remember and pass on.
SOI Marketing Tools and Automation
Engagement data has limited value if nobody acts on it. Define who receives alerts, how quickly they should respond and how the outcome will be recorded.

The Next Steps To A Better SOI
ActivePipe is an email marketing automation platform built for real estate organisations in Australia and New Zealand.
It helps teams maintain consistent communication through property-focused campaigns, behavioural insights and relevant property content. Its Intent Engine combines contact responses with engagement signals to help agents identify possible opportunities within their existing database.
Smart Property Matching uses known preferences and behaviour to send contacts more relevant listings. Pre-built campaigns and market content also reduce the amount of material agents and marketing teams need to create manually.
For brokers and enterprise groups, that means:
- More consistent communication across agents and offices
- Central campaign management with room for agent and office personalisation
- Better use of property, contact and engagement data
- Clearer prompts for agent follow-up
- Greater visibility into campaign and contact engagement
- More opportunities to start conversations with existing relationships
Your database is already full of relationships you spent years and marketing dollars building. The next appraisal, listing or referral may already be there.
