Meet Shannon. She runs a boutique real estate agency in a mid-market pocket of Sydney where the average sale sits between $1.2m and $2m. The kind of suburb where the agent who knows the street, the schools, and the strata politics gets the listing.
For the last 18 months, Shannon's prospecting was outsourced to two overseas telemarketers. Over $1,500 AUD a month, every month. The vendors hung up a lot.
In January 2026 she switched.
Marrickville. Drummoyne. Five Dock. Streets that are not making the front page of the property pages, but where Shannon's vendors live. Houses that look something like this. Federation brick. Sandstone footings. A frangipani out front older than the current owners.
Vendors here have specific questions. What is the ICSEA at the local primary? How long is the bus to Wynyard at 8am in peak traffic? Has the strata finalised the cladding works? What did the comparable terrace on the next street go for last month?
The agent who can answer those questions wins the listing. Two telemarketers reading from a generic script could not.
The Funnel
What 10,000 dialled phones produced
8 campaigns ran from January through March. Just under 10,000 distinct phones dialled. 10,713 total dial attempts (1.08 per phone, no aggressive retry pattern, one ring then move on).
Of those 10,713 calls:
| Outcome | Count | % of all calls |
|---|---|---|
| Any human pickup | 3,609 | 33.7% |
| ↳ Real conversation (≥30s) | 1,997 | 18.6% |
| ↳ Very short connect (<30s, hung up) | 1,612 | 15.0% |
| Voicemail | 3,618 | 33.8% |
| Rang out / dead line | 3,486 | 32.5% |
The bit that mattered: the 1,997 real conversations. Anything under 30 seconds is usually someone who hung up before the agent got a chance, even on a witty agent that breaks the ice fast and slips the key qualifying question in early ("are you looking to buy or sell your property?"). Anything that hits voicemail does not get a script played at it. The platform only counts the calls where a human and the agent actually had a back-and-forth long enough to learn something.
The Sellers
The 141 sellers (and what 7.1% means)
Of those 1,997 real conversations, the agent identified 141 prospects who were genuinely thinking about selling, qualified them, and live-transferred them to Shannon while still on the line.
Another 26 prospects asked Shannon to call them back personally. 26 more asked for a six-month check-in (a tag the platform queues automatically into the next quarterly campaign, so the warm pipeline keeps compounding).
| Outcome | Count | % of real conversations |
|---|---|---|
| Live transferred to Shannon | 141 | 7.1% |
| Asked Shannon to call back | 26 | 1.3% |
| Asked for 6-month callback | 26 | 1.3% |
| ANY interest signal | 193 | 9.7% |
The Spend
What it cost
50+ hours of real conversation
In 90 days, the agent racked up 50.9 hours of pure talk time with potential vendors. Just the conversations. Not the dial time, not the voicemails, not the dead lines underneath. To produce that talk volume manually, Shannon would be on the phone for hours every working day, never mind all the dialling it takes to get those conversations to happen. The agent does it in the background while she lists houses.
- Total spend across all 8 campaigns$4,617.03 NZD
- Total talk time50.9 hours (3,054 min)
- Average cost per call$0.43
- Average cost per real conversation$2.31
- Cost per warm-transferred seller$32.74
$32.74 to put a qualified vendor in front of Shannon, on the phone, ready to talk. $23.92 if you widen the lens to any interest signal (warm transfer plus callback request plus 6-month re-engagement).
For comparison: Shannon was paying her two overseas telemarketers more than $1,500 AUD per month, every month. Roughly the same in NZD as the AI agent has cost across the entire 3-month window. With far fewer dials, far fewer leads, and zero ability to follow up at midnight on a Wednesday.
Why The Switch
Why offshore stopped working
Two reasons.
When a vendor says "we are looking at maybe selling once strata sorts the cladding", the agent knows what cladding remediation means for this building cycle and what it does to a vendor's timing. When they say "the bus is a nightmare from here", the agent knows whether they are right or whether the new metro changed it.
That is the layer two telemarketers reading from a generic script in another country do not have. Not because they are not competent. Because nobody hands a contract worker overseas the My School ICSEA scores for inner west Sydney before each shift.
Honest Framing
The honest math (and the caveats)
Three caveats so nobody buys with the wrong expectation.
The Pipeline
141 vendor leads is a waterfall, not a wall
Shannon is not listing 141 houses next month. That is not how this works.
What 141 means for her business: a multi-year waterfall of warm vendors at different stages of selling. Some are listing in 6 weeks. Some in 6 months. Some in 18 months once strata sorts the cladding or the kids finish at the local primary. The agent flagged all 141 as serious enough to talk to and warm enough to transfer to Shannon live. She now owns the relationship.
Meanwhile the rest of the database keeps growing. Shannon adds new contacts from her own social media posts, auction sign-ins, open home walk-ins. Every 90 days the agent re-runs the campaign on the full database, the new additions and the original 141.
Here is where it compounds. The agent does not call the 141 again from a fresh script. It opens with the context from the last conversation: "Hi, last time we spoke you mentioned you were waiting on the strata cladding works to wrap before listing. I wanted to check where that landed."
That opener does not happen with two telemarketers in another country reading from a fresh template every quarter. It is the difference between a one-off campaign and a pipeline that compounds.
Where Shannon is now
90 days in, the agent is on its 9th campaign. She has stopped paying offshore. Her CPA on warm vendor transfers is sitting in the low $30s. The portfolio is filling.
If you are running a boutique real estate practice in NZ or Australia and you are paying for prospecting that does not understand your market, the maths above are now a known quantity rather than a guess.
