Real estate ISAhuman, AI or both
What a real estate ISA does, what one costs, how an AI ISA compares, and how teams split the work between them.
Your team gets 300 new leads a month. Your agents are out at site visits and listing appointments all day, so most of those leads wait until the evening, and some never get a call at all.
That's the moment most team leads start asking whether they need a real estate ISA.
This guide explains what an inside sales agent actually does, what goes into the cost of hiring one, and how an AI ISA compares, including the places where a person is still clearly better.
- What is a real estate ISA? A real estate ISA, or inside sales agent, is the person on a team who contacts new leads, qualifies them and books appointments for the agents, so the agents can spend their time with clients.
- What does an ISA cost? There's no official salary figure for real estate ISAs. Expect a base wage, commission or a bonus per appointment, payroll costs, a dialer and CRM seats, and the time it takes to train and manage them.
- What is an AI ISA? An AI ISA is software that does the first part of the ISA job: it answers new leads in seconds, asks qualifying questions, books site visits and follows up, at any hour.
- Which should you choose? Often both. Let AI answer every lead instantly and handle the repetitive follow-up, and keep people for phone conversations, nurturing long-term sellers and handing warm leads to agents.
What a real estate ISA is
An inside sales agent, or ISA, is the person on a real estate team whose job is to talk to leads, not to sell homes. They call, text and email new buyers and sellers, find out who is serious and book appointments for the agents who do the selling.
The role exists because agents are bad at speed. Not because they don't care, but because they're in a car, at a site visit or at a listing appointment when a lead comes in. An ISA sits at a desk with the CRM open and makes sure somebody answers.
Speed matters more than most teams think. In a 2011 Harvard Business Review study of 2,241 US companies, firms that tried to reach a lead within an hour were nearly seven times as likely to qualify it as firms that waited longer.
The average response time among companies that responded at all was 42 hours.
And Zillow's 2026 buyers report found that 54% of buyers who contacted an agent contacted only one before hiring them. For about half of buyers, the first agent they talk to is the one they hire.
Inbound ISAs and outbound ISAs
Teams usually split the role in two. Inbound ISAs work new leads from your website, portals, ads and sign calls, where speed is everything.
Outbound ISAs call old leads, past clients, expired listings and sphere contacts, where persistence and phone skills matter more. Some teams hire one person to do both. Bigger teams separate them.
What a real estate ISA does all day
Most ISAs work out of a CRM such as Follow Up Boss, which sells features built for this role: a dialer, lead routing rules, live transfer to an agent's cell phone and booking straight onto agents' calendars. A typical day looks like this:
- New lead response. Call or text every new lead as it arrives, ideally within minutes.
- Qualification. Find out whether they're buying or selling, their timeline, price range, location, financing and whether they already have an agent.
- Booking. Set a site visit, a buyer consultation or a listing appointment on the right agent's calendar.
- Live transfers. Pass a hot lead straight to an agent's phone while they're still on the line.
- Follow-up. Work the long list of leads who aren't ready yet, sometimes for months.
- Database calls. Reconnect with past clients and old leads to find new business.
- CRM hygiene. Log every call and note so agents walk in knowing the story.
Volume is the job. One Follow Up Boss customer says its ISA team makes 200 to 300 calls a day using the dialer. It's demanding, repetitive work, and when an ISA leaves, the training and scripts walk out with them.
What a real estate ISA costs
There's no government salary figure for real estate ISAs. The Bureau of Labor Statistics doesn't track "inside sales agent" as its own occupation, and the big salary sites mostly report generic inside sales or real estate agent pay.
What BLS does publish is pay for the closest occupations, from its May 2025 wage survey:
| BLS occupation (closest to an ISA) | Median hourly wage | Median annual wage |
|---|---|---|
| Customer service representatives (in real estate) | $21.02 | $43,720 |
| Telemarketers (all industries) | $17.04 | $35,450 |
| Real estate sales agents (all industries) | $25.40 | $52,830 |
| Sales reps of services (in real estate) | $35.19 | $73,200 |
Read these as a range, not a price tag. An ISA who mostly dials and books sits closer to the first two rows.
An experienced ISA who converts well, or a licensed one who can talk about contracts, sits closer to the bottom two. Pay plans vary too, for example a base plus a bonus per kept appointment or a share of closed deals.
The full cost of an ISA
Wages are only part of it. When you budget for an ISA, add up:
- Base pay and any guaranteed hours.
- Variable pay, such as a bonus per appointment, per kept appointment or per closing.
- Payroll costs, such as employer taxes and any benefits, if they're an employee.
- Software: a CRM seat, a dialer, phone numbers and texting.
- Hiring and training: scripts, role-play, call reviews and the weeks before they're productive.
- Management time: someone has to coach them, check the numbers and keep agents honest about following up.
- Coverage gaps: an ISA works one shift. Nights, weekends, holidays and sick days need a plan too.
Calling rules every ISA needs to know
ISAs make a lot of calls and texts, so the rules apply to them every day. This is a quick summary, not legal advice:
- Calling hours. The FCC's rules ban telephone solicitations to residential numbers before 8am or after 9pm, local time where the person is.
- Do Not Call. You can't make sales calls to numbers on the National Do Not Call Registry without an exemption. The FTC says telemarketers must sync their lists with the registry at least every 31 days.
- Inquiries. When someone asks about a property, the FTC treats that as a business relationship for three months from the inquiry. After that, the registry applies again.
- Opt-outs. If someone asks you to stop calling, stop. Calling them again breaks the FTC's Telemarketing Sales Rule.
- Autodialers and prerecorded or artificial voices. Telemarketing calls to cell phones made this way need the person's prior express written consent.
Check with your broker or a lawyer on how these apply to your team, especially for outbound calls to old leads and expired listings.
What an AI ISA is, and what it does
An AI ISA is software that does the first part of the ISA job, the part that's mostly speed and repetition.
When a new lead comes in, it replies within seconds, answers questions about the listing, asks your qualifying questions and books a site visit on the right agent's calendar. Then it keeps following up with leads who aren't ready yet.
Several real estate vendors now sell this. Ylopo, for example, describes its AI text as "your always on automated ISA".
The products differ a lot in which channels they cover (text, website chat, WhatsApp, voice), whether they book on real calendars and how they hand a lead to a person.
Where an AI ISA does well is the part people find hardest to keep up:
- It answers at 10pm on a Saturday, and on holidays, without overtime.
- It replies in seconds, every time, even when 40 leads arrive at once after a new listing goes live.
- It follows up without forgetting. Day 3, day 10 and day 30 happen whether anyone is in the office or not.
- It's consistent. Every lead gets the same qualifying questions, and every answer lands in the CRM.
- It works where buyers write. Zillow's 2026 report found text was buyers' most preferred way to talk to their agent (43%), and an AI ISA can work text, website chat and WhatsApp at the same time.

On a real estate site, the same agent answers buyers about your listings, asks your qualifying questions and books the site visit, at 10pm or 10am.
Human ISA vs AI ISA: an honest comparison
| Compare | Human ISA | AI ISA |
|---|---|---|
| First reply | Minutes during their shift, hours outside it | Seconds, at any hour |
| Hours covered | One shift, unless you hire more | Around the clock |
| Lead volume | Limited by how many calls one person can make | Handles spikes without waiting |
| Phone conversations | Strong, especially with hesitant sellers | Depends on the product. Many are text first |
| Reading people | Picks up on tone, hesitation and family dynamics | Follows what the lead says, less of what they don't |
| Long-term nurture | Builds real relationships over months | Consistent reminders, lighter relationship |
| Outbound calling to old leads | A core strength | Limited, and tightly regulated for automated calls |
| Consistency | Varies by day and by person | Same questions every time |
| Cost shape | Wages, payroll, software, management | A monthly subscription |
| Turnover risk | Real, and you lose the training when they leave | None, though someone still owns the setup |
Where a human ISA is still better
Be honest about this before you replace anyone.
A good human ISA is better at the conversations that decide big deals: a seller who's nervous about pricing, a divorcing couple who need to sell, a past client who wants to talk through whether now is the right time.
They're also better at outbound work, calling old leads and expired listings and turning a cold "no" into a meeting six months later. And they can tell an agent things about a lead that never show up in a transcript.
Where an AI ISA is better
AI wins on everything that depends on speed, hours and patience: the first reply, the 11pm Zillow inquiry, the 40 messages after an open house, the tenth polite follow-up. Those are exactly the tasks that burn out human ISAs and the ones agents skip when they're busy.
How teams combine an AI ISA with people
Most teams don't need to pick one. A setup that works well:
- AI answers every new lead first
Website, portal, ad and WhatsApp leads get a reply in seconds, day or night, with answers about the listing.
- AI qualifies and books the easy ones
Buyers who know what they want get a site visit booked on the right agent's calendar straight away.
- People take the conversations that need judgment
Sellers, high-value buyers and anyone who asks for a person get handed to your ISA or agent, with the full conversation attached.
- AI keeps the long tail warm
Leads who aren't ready get regular, useful follow-up, so your ISA's time goes to the ones who are.
- Your ISA focuses on outbound and nurture
Past clients, sphere and old leads, where a real phone conversation makes the difference.
This turns one ISA into a much bigger operation. It's also a good way to start if you can't hire yet: let AI cover speed and after-hours now, and hire a person when the booked appointments justify it.
The real estate lead generation guide covers where those leads come from in the first place.
How to decide what your team needs
Start with an AI ISA so every lead gets a reply in seconds. It's the quickest fix for speed to lead.
Cover the hours no one is working, and book site visits overnight with an AI appointment setter.
Outbound calling and relationship nurture still work best with a person on the phone.
AI handles the first reply and follow-up, and your ISA handles calls that need judgment.

Real estate ISA questions
ISA stands for inside sales agent. A real estate ISA contacts and qualifies new leads and books appointments for the team's agents.
A real estate ISA calls, texts and emails new leads, qualifies them by timeline, budget and needs, books site visits and listing appointments for agents, and follows up with leads who aren't ready yet.
There's no official salary figure for real estate ISAs, because BLS doesn't track the role separately. The closest BLS occupations had median wages from about $35,000 to $73,000 a year in May 2025, and some pay plans add a bonus per appointment or per closing.
It depends on your state and what the ISA does. Rules on what unlicensed assistants can discuss vary, so check with your state's real estate commission and your broker.
An AI ISA is software that replies to new real estate leads in seconds, asks qualifying questions, books site visits and follows up automatically, at any hour.
An AI ISA can replace part of the job, mainly the first reply, after-hours coverage and routine follow-up. A human ISA is still better at outbound calling, nervous sellers and long-term relationships, so many teams use both.
A real estate ISA is usually worth it when your agents can't answer leads quickly enough to keep up with volume. If most of the problem is after-hours leads or response time, an AI ISA may solve it for less.
Many real estate ISAs work in Follow Up Boss, which includes a dialer, lead routing and booking on agents' calendars. Other teams use the CRM their brokerage provides.
