Why real estate agencies need a custom GPT
Public ChatGPT can't see your CRM. It doesn't know which suburbs you specialise in, what's currently on RP Data, or how your principal worded the last 50 contracts of sale. That's why a generic AI tool always feels like a junior agent on day one.
A custom GPT for your agency is trained on your actual listings, your contract templates, your suburb reports, and your team's playbook. It answers in your voice, knows your stock, and follows your compliance rules — including NSW Fair Trading, Consumer Affairs Victoria, and the new Queensland tenant law changes.
What we typically build for real estate offices
Property Description Writer
Turn 6 photo URLs and a feature list into a 180-word REA-style description in 12 seconds. Trained on your top-performing past listings.
Buyer FAQ Assistant
Embedded on your website. Answers strata fees, council rates, school catchments, and recent comparable sales — without sending a human until intent is qualified.
Contract Q&A Bot
Lets sales agents ask 'is this vendor liable for the holdover period?' and gets a citation-backed answer from your standard cooling-off and special conditions library.
Tenant Maintenance Triage
Categorises tenant requests (urgent / non-urgent / not landlord), drafts the response, and routes to the right tradie. Used by property managers handling 200+ tenancies.
Data sources we connect
- REA & Domain feeds — pulls live listings via your portal API
- RP Data / CoreLogic — comparable sales, suburb medians, days-on-market
- Your CRM — Box+Dice, Vault RE, Eagle Software, AgentBox, Rex
- Trust accounting — PropertyMe, Console, MRI
- Contract & disclosure templates — your firm's signed precedents
What changes for your agents
Most agencies we work with see four shifts in the first 60 days: response time on portal enquiries drops from 4 hours to under 5 minutes, agents reclaim 6–9 hours per week from listing-description and contract-question work, principal involvement on routine compliance questions falls by half, and after-hours buyer enquiries are captured instead of lost to a competitor's faster reply.
Compliance built in. We harden the system prompt against giving legal or financial advice, log every conversation for audit, and make sure responses include 'verify with your conveyancer' language where required. Your custom GPT acts as an admin assistant, not a licensed agent.
Frequently asked questions
Can the GPT write listing descriptions in our agency's voice?
Yes. We fine-tune on 30–60 of your highest-performing past descriptions so the output matches the cadence, length, and feature ordering your principal already approved. Most agencies don't need to edit the output before publishing to REA.
Does it integrate with our CRM (Box+Dice, Rex, AgentBox)?
Yes. We support read-only integrations with all major Australian real estate CRMs via their REST APIs or webhook feeds. Write-back into the CRM is also possible but requires your CRM admin to issue an API key with the relevant scopes.
Is RP Data and CoreLogic data licensed properly when used inside the GPT?
Your CoreLogic licence agreement determines what can be passed to a third-party model. We deploy in 'private retrieval' mode — comparable sales data stays in your tenant and is only used to compose the answer, never sent to OpenAI for training. We can show you the data flow on request.
How long does it take to deploy?
A single-agency Property Description Writer takes about 5–7 working days. A full Buyer FAQ + Contract Q&A + tenant triage suite takes 3–4 weeks including data ingestion, testing on your top 200 historical questions, and team training.
