An ISA, or inside sales agent, is the person on a real estate team whose whole job is contacting new leads, following up with old ones, and booking appointments on the agent's calendar. The agent sells. The ISA makes sure there's someone to sell to.
If you've been told to "hire an ISA" and you're a solo agent looking at the price, this page is the honest version: what the role covers, what it costs at market rate, and the point at which the maths stops working.
ISA meaning, in one line
Inside sales agent. "Inside" because the work happens on the phone and by text rather than in the field. On a large team the ISA sits between the marketing spend and the licensed agents: leads arrive, the ISA reaches them fast, finds out what they're looking for and when, and puts the ones who are ready onto an agent's calendar.
Two things worth being precise about, because they decide what an ISA is legally allowed to do:
- An ISA may or may not be licensed. Many are unlicensed administrative staff.
- Advice is licensed activity. Anything touching price, terms, property condition or negotiation belongs to a licensed agent. Setting appointments and gathering timeline generally does not. Rules vary by state. Check yours before you write a job description.
What an ISA does all day
- Answers new leads as they land: portal enquiries, website forms, missed calls
- Works the follow-up list: the leads from three weeks ago who went quiet
- Confirms interest, area and timeline, and notes what the person actually asked for
- Books showings and calls onto the agent's calendar
- Keeps the CRM honest so nothing sits untouched
- Routes anything about price, terms or condition straight to the licensed agent
It is unglamorous, repetitive work, and it is the difference between a lead and a client.
What an ISA costs
This is where most solo agents stop reading job boards.
| Cost | Monthly |
|---|---|
| Base pay | $4,000 – $5,000 |
| Fully loaded: payroll taxes, dialler, CRM seat, training, management time | $4,600 – $7,100 |
| Hours covered | Business hours. Not weekends, not 9pm. |
Team leads generally pay the loaded number and know it. And loaded cost is only half the story: an ISA needs recruiting, scripts, onboarding, and someone to manage them, which is usually you, in the hours you were going to spend selling.
When hiring an ISA makes sense, and when it doesn't
It makes sense when you have more lead volume than you can personally answer, a predictable source feeding it, and enough transaction volume that one extra closing a month covers the salary. That is a real situation and plenty of teams are in it.
It doesn't make sense for most agents, and the membership data says why. 86% of REALTORS are independent contractors at their firm and only 21% work on a team (NAR membership data). The median agent closes 9 sides a year on about $9,530 of total business expenses (NAR). A $4,000-a-month hire is not a line item that fits in that budget. It is several times the entire budget.
So the question for most agents was never "which ISA should I hire". It was "how do I get leads answered when I'm the only one here".
Virtual ISAs and real estate ISA companies
The market's answer has been to make the hire cheaper rather than smaller. Broadly there are three routes:
- In-house ISA. Most control, highest cost, and you own the management.
- Virtual ISA / offshore ISA. Lower hourly cost. You still own scripts, quality and turnover, and the person is on their timezone, not your leads'.
- ISA call centres. Someone else manages the staff. You give up voice and context, and you're usually buying a block of hours whether leads arrive in them or not.
All three share the same shape: you are paying for availability by the hour, and leads don't arrive by the hour. They arrive while you're mid-showing, on the other line, at dinner, or asleep.
The AI ISA: same job, different cost base
An AI ISA does the first slice of the ISA's work, the part that has to happen in the first minute, and hands the rest to you.
That's what Apanto is. A new lead texts or calls, and Apanto answers by text in under 60 seconds, in your voice, day or night. It confirms interest, asks about area and timeline, and keeps the conversation warm until you can take it. You approve every message before it sends, until you've read enough of them to trust it on autopilot, and you can switch it off from your phone with one text.
What it deliberately does not do: negotiate, put a value on a property, advise on terms, or answer financing questions. Those escalate to you. It never claims to be a person, either. If a lead asks, the question goes to you.
Why the first minute is the whole game
Most clients never run a second interview. 67% of first-time buyers and 76% of repeat buyers interviewed only one agent before choosing. 74% of sellers contacted only one agent before listing (NAR 2025 Profile of Home Buyers and Sellers).
Three out of four sellers only ever talk to one agent. Being the one who answers is being the one they hire.
And the cost of not answering is not abstract. A single Zillow lead connection runs $223 in major metros and $139 outside them (Zillow published rates). A lead you paid for and didn't reach is that much money, gone, plus the commission behind it.
What it costs
| Monthly | |
|---|---|
| ISA, fully loaded | $4,600 – $7,100 |
| Apanto, solo agent | $149 founding rate $89, locked 12 months |
| Apanto, brokerage seats | $99 per agent, 3-seat minimum |
For context on whether that's a normal spend: 34% of REALTORS spend $50–250 a month out of pocket on technology, 20% spend $251–500, and 24% spend over $500 (2025 REALTORS Technology Survey, NAR). It's a real decision at a median agent's expense level. It is not, however, an unusual one.
Founding solo signups carry a 30-day money-back guarantee. If it isn't earning its place in the first month, you ask and it's refunded.
An ISA costs $4,000 a month and sleeps. Apanto answers in 60 seconds.
Questions agents ask
Is an ISA the same as a transaction coordinator?
No. A transaction coordinator manages a deal that already exists: paperwork, deadlines, closing. An ISA works the front of the funnel, before there's a deal at all.
Does an ISA need a real estate licence?
Often not, but it depends on the state and on what you ask them to do. Setting appointments and gathering timeline is generally permitted for unlicensed staff; advising on price, terms, condition or negotiation is licensed activity and the exposure lands on your licence. Check your state's rules before writing the role.
What does an ISA earn?
Market rate is roughly $4,000–5,000 a month in base pay, and $4,600–7,100 a month fully loaded once you count payroll costs, tools, training and the time you spend managing them.
Can an AI ISA replace a human one?
Not the whole role. It replaces the first minute (answering, staying in the conversation, keeping the lead warm), which is the part that has to happen instantly and the part that most often doesn't. Nurture calls, deep follow-up and every licensed conversation stay human.
Will my leads know it's automated?
Apanto writes in your voice and most leads read it as a normal text. It will never claim to be a person: if someone asks whether they're talking to a bot, that conversation goes straight to you to answer. And until you turn on autopilot, nothing sends without your approval.
