What is an ISA in real estate? A guide to inside sales agents
An ISA in real estate is an inside sales agent: the person on a team who answers new buyer and seller leads, qualifies them and books the appointment, so licensed agents spend their time with clients who are ready to move.
This guide covers what an ISA does day to day, how the role differs from the others on a team, the questions an ISA asks, what one earns and costs, the numbers to track, and where an AI ISA fits. If you already know the role and want the leads answered tonight, see our AI ISA for real estate agents and teams.

What an ISA does day to day
An ISA owns the first conversation with every lead. On a busy team that means a steady stream of portal inquiries, website forms, sign calls, open house sign-ins and old database contacts, all landing at different hours and all expecting a quick answer. The ISA's job is to turn that stream into booked appointments and clean notes.
A typical day runs like this:
Answer new leads first
New inquiries come before everything else, because a lead is most likely to answer in the first few minutes after asking. The ISA calls, texts or emails back while the buyer is still on the listing page.
Qualify
Buying or selling, timeline, price range, financing, whether there is a home to sell first, and whether they already have an agent. The same questions on every call, so the agent gets a decision rather than a name and a phone number.
Book the appointment
A buyer consultation, a showing, or a listing appointment, straight into the agent's calendar, with a confirmation to the client.
Hand over with notes
The ISA writes up what the client said in the CRM and, on many teams, briefs the agent directly. A warm handoff is the difference between "Dana from Quillfern Realty asked me to call" and starting over.
Follow up and nurture
Most leads are not ready this week. The ISA works a follow-up plan by phone, text and email for months, and calls back through the database to find past clients and old leads who are ready now.
Confirm and track
Reminders the day before, a check that the appointment happened, and the numbers logged: leads contacted, appointments set, appointments kept.
What an ISA does not do matters just as much. An ISA does not show homes, write offers, negotiate, or give opinions that need a license. Those go to the agent.
ISA vs buyer's agent vs transaction coordinator vs showing assistant
Teams use these titles loosely, so it helps to sort them by where each one sits in the life of a deal. The ISA works before there is an appointment. Everyone else works after.
| Role | Where it sits | What it does | License |
|---|---|---|---|
| Inside sales agent (ISA) | Before the appointment | Answers, qualifies, books and follows up with new and old leads. | Depends on the state and the tasks; see the licensing section below. |
| Buyer's agent | From the first meeting to closing | Consults with buyers, shows homes, writes and negotiates offers. | Licensed. |
| Showing assistant | During the home search | Opens homes and walks buyers through them for the lead agent. | Usually licensed, because showing property is licensed work in most states. |
| Transaction coordinator | From contract to closing | Tracks deadlines, paperwork, inspections and the closing file. | Varies by state and by the tasks. |
The common mistake is asking one person to do two of these. A buyer's agent who also has to answer every new lead ends up doing neither well: leads wait while the agent is at a showing, and showings suffer while the agent works the phone.
Inbound vs outbound ISA
Larger teams split the role in two, because the work and the temperament are different.
Inbound ISA
Works leads that came to you: portal and website inquiries, sign calls, ad responses and callbacks. The whole game is speed and consistency. These people asked to hear from you, so the ISA's job is to reach them fast, qualify them and book the appointment before another team does.
Outbound ISA
Works leads the team goes looking for: past clients, the sphere, expired and withdrawn listings, old leads in the CRM, and other prospecting lists. Outbound takes more resilience and much tighter compliance. Sales calls to people who have not given you consent bring Do Not Call screening, calling hours and consent rules into play, AI-voice sales calls need prior express written consent even for leads who inquired, and in some states it is work only a licensed agent may do.
If you can only fund one, most teams start inbound. Leads you already paid for are the cheapest appointments you will ever get, and they are the ones most likely to go cold while nobody answers.
Qualifying a lead: the question set for buyers and sellers
A good ISA works from a short, fixed set of questions and writes the answers where the agent will see them. The exact wording is yours; the point is that every lead gets the same questions, so leads can be compared and routed.
Buyer questions
- Where are you looking, and what kind of home?
- When would you like to move?
- What price range are you comfortable with?
- Have you spoken with a lender, or would you like an introduction?
- Do you need to sell a home before you buy?
- Are you already working with an agent?
- Would you like to see this home, or talk through the search first?
Seller questions
- What is the property, and where is it?
- When would you like to sell, and what is prompting the move?
- Where are you moving to, and do you need to buy there?
- Do you have a price in mind?
- Has the home been listed before?
- Who else is involved in the decision?
- When can an agent walk through the home with you?
Two rules keep this clean. First, the ISA asks about the client's plans, never about who the client is: no questions or comments on race, color, religion, sex, disability, familial status, national origin or the makeup of a neighborhood. The federal Fair Housing Act bars steering on protected characteristics, so anyone who asks is pointed to public, objective sources. Second, the ISA does not offer a price opinion or advice on terms. That is the agent's conversation.
Skills and tools of a good ISA
The best ISAs are not the best talkers. They are the most consistent. A good ISA:
- Calls back in minutes, every time, including the lead that came in during lunch.
- Asks the same questions on every call and writes the answers down where the agent will read them.
- Listens more than talks, and hears the timeline behind "just looking."
- Handles "I already have an agent" and "not yet" without pushing.
- Follows a follow-up plan for months without letting leads slip.
- Knows the market well enough to sound credible, and knows where the line is on licensed advice.
- Knows the calling rules: consent, calling hours and Do Not Call.
The tools are simple: a CRM that holds every lead and every note, a calendar the ISA can book into, a phone and texting setup tied to the CRM, a dialer for outbound work, and recorded calls so a manager can coach. Recorded calls are worth more than most teams use them for. Reviewing a sample each week against your script is how you find the lead the ISA lost and the question nobody asked. If your team already records its calls, our call quality monitoring reviews them against a checklist written from your script, from $95 per agent per month.
What an ISA earns and what one costs a team
Pay for the role varies widely by market, experience and how much of it is tied to results. Industry research gives a working range:
- Annual pay. Industry research puts a salaried real estate ISA at about $55,000 to $65,000 a year.
- Incentive pay. Many plans tie part of the pay to results: a bonus per appointment set or kept, a share of closed commissions, or both.
- First-year cost. Once recruiting, training and ramp are counted, industry research puts an in-house ISA at about $75,000 to $85,000 in the first year.
- Turnover. Industry research estimates replacing an ISA who leaves at about $18,000 to $22,000 per departure, before the leads lost while the seat is empty.
- Virtual ISA services. Industry research puts virtual ISA services at about $720 to $3,000 or more a month, from part time to full time.
The salary is only part of the cost. A new ISA takes weeks to recruit and train before they book well, covers one shift, and can only work one lead at a time. The number that matters is cost per kept appointment, which the metrics section below helps you measure.

Four ways to fill the ISA seat
There are four ways to fill the seat. Most teams end up with a mix.
| Option | Hours covered | Strengths | Watch for | Cost |
|---|---|---|---|---|
| In-house ISA | One shift | Knows your market and your agents; builds long relationships. | Hiring, ramp, turnover; nights and weekends uncovered. | About $75,000 to $85,000 in the first year, per industry research |
| Outsourced ISA service | Set by contract | No hiring; a trained caller from day one. | Shared callers who learn your market slowly; script drift. | Varies by provider and hours |
| Virtual ISA service | Part time to one full shift | Lower cost per seat. | Time zones, call quality, management time. | About $720 to $3,000 or more a month, per industry research |
| AI ISA from Ad Nomina | Inbound 24/7; outbound within permitted calling hours | Answers in seconds, works every lead at once, the same questions every time. | Does not close or negotiate; hands those to your agents. | Quoted after scoping |
The AI ISA is priced as a one-time setup fee plus a monthly fee, quoted once we have scoped the work with you. Third-party figures above are industry research and not a quote.
Metrics: how to measure an ISA
Five numbers tell you whether the seat is working. Track them weekly, by lead source.
Speed to lead
Minutes from a lead arriving to the first real contact attempt. This is the number most teams are shocked by when they first measure it, especially for leads that land after hours.
Contact rate
The share of new leads the ISA actually speaks with. Low contact rates usually mean slow first attempts or too few follow-ups.
Appointment set rate
Appointments booked as a share of leads contacted. This shows whether the qualifying conversation turns into a next step.
Appointment kept rate
Appointments that actually happen as a share of those set. A low kept rate points at weak qualification or missing reminders, not at the agents.
Lead to close
Closed deals as a share of all leads, by source. It takes months to read, but it is the number that pays for the seat.
Pay attention to the handoff too. If kept appointments are high but agents say the notes are thin, fix the question set before you fix the ISA.
When a team should hire an ISA
You probably need an ISA when one or more of these is true:
- You pay for leads, and nobody can tell you how fast each one was answered.
- Leads that arrive in the evening or at the weekend wait until the next business day.
- Your agents spend more hours chasing new leads than meeting clients.
- Your CRM holds thousands of old leads and past clients that nobody calls.
- Two agents on the team have both called the same lead, or neither has.
- Your top producer is booked solid and is still answering every inquiry personally.
You probably do not need one yet if a single agent answers a handful of leads a week and can reach each of them in minutes. For everyone in between, the question is less whether to fill the seat and more how: a hire, a service, an AI ISA, or a mix, such as an AI ISA for speed and nights with a human ISA for your database.
Do real estate ISAs need a license?
It depends on your state and on what the ISA does. There is no single national rule. Each state real estate commission decides which activities need a license, and the line usually falls between administrative work and soliciting or advising clients.
Texas is a useful example of how strict that line can be. Guidance from the Texas Real Estate Commission says: "An unlicensed assistant cannot make calls to determine whether a person is interested in buying, selling, or leasing property, even if it is to schedule a follow-up appointment with a license holder to discuss details." The same guidance says: "An unlicensed assistant may arrange a showing appointment on behalf of the license holder who will show the property." In Texas, then, much of what an outbound ISA does is licensed work.
Other states draw the line in other places. Before you hire, outsource or automate the role, check with your state real estate commission and your broker, and write down which tasks your ISA may do. The same question applies to an AI ISA: where your state treats outbound lead qualification as licensed activity, keep that work with licensed people.

Where an AI ISA fits
An AI ISA does the first part of the job, the part that depends on speed and consistency. An inquiry lands at 9:40 on a Sunday night. Your agents are with their families. Our AI ISA picks up a call to your line in seconds, or replies to a form inquiry by email, or by WhatsApp where the lead opted in, and asks whether the person is buying or selling, their timeline, price range, financing and whether there is a home to sell first, books the showing into your calendar, and leaves the notes in your CRM. An AI call back to a form lead happens only when the lead has given prior express written consent, and only within permitted calling hours. It does not close. It books, and it hands over. See the AI ISA for real estate agents and teams.
Every call opens with the same disclosure: "You are speaking with an automated AI assistant, and this call may be recorded." It stays neutral on fair housing and passes anything that needs a license to your agents. Outbound AI calls run only with the lead's prior express written consent, within permitted calling hours and after Do Not Call screening. We connect it to your CRM and calendar during setup, where an integration is available, so nobody on your team logs into a new system. For setup and the handoff in detail, see how the AI ISA handles speed to lead.
It is one of our AI voice agents. For the conversations that need a person, we can introduce you to a partner call center that provides nearshore live call center agents, with licensed conversations staying with your own agents. And when your own ISAs take the calls, we review the recordings against your script.
The best way to judge an AI ISA is to hear one. Talk to an agent and put it through the questions your leads ask, or tell us how your leads come in today.
Real estate ISA questions
What does an ISA do in real estate?
An ISA answers new buyer and seller leads, asks the qualifying questions, and books appointments for the licensed agents on the team. The ISA also follows up with leads who are not ready yet and keeps notes in the CRM, so agents spend their time with clients who are ready to move rather than chasing every inquiry.
What does ISA stand for in real estate?
ISA stands for inside sales agent. "Inside" means the work happens on the phone, by text and by email rather than in the field. The ISA works the leads from the office or from home, while the licensed agents go out to showings, listing appointments and closings with the clients the ISA has qualified.
What is an ISA team in real estate?
An ISA team is a real estate team that splits the work: one or more inside sales agents answer and qualify every lead, and the licensed agents take the appointments the ISAs set. The split lets each person do one job well. Larger teams often run several ISAs, sometimes with separate inbound and outbound roles.
How much does a real estate ISA make?
Industry research puts a salaried real estate ISA at about $55,000 to $65,000 a year. Many plans also tie part of the pay to results, such as a bonus per appointment set or kept, or a share of closed commissions. Pay varies widely by market, experience and lead volume, so treat these figures as a starting point, not a benchmark.
Do real estate ISAs need a license?
It depends on the state and on the work. In Texas, for example, the real estate commission says an unlicensed assistant cannot make calls to find out whether someone wants to buy, sell or lease, but can arrange a showing appointment. Check with your own state real estate commission before you hire or assign the work.
What is the difference between an ISA and a showing assistant?
An ISA works leads before an appointment exists: answering, qualifying and booking. A showing assistant works after that, opening the door and walking buyers through homes on behalf of the lead agent. Showing assistants are usually licensed agents themselves, while what an ISA may do without a license depends on your state.
Where does an AI ISA fit on a team?
They are good at different things. An AI ISA answers every inbound lead in seconds, at any hour, and asks the same questions every time. A human ISA handles nuance, long relationships and conversations that need a license. Many teams use an AI ISA for speed and coverage and keep people for the conversations that matter most.
How do I set up an ISA on my team?
Start with your lead sources and response time today. Write the qualifying questions for buyers and sellers, decide what counts as an appointment, and set the handoff to your agents. Then choose a hire, an outsourced ISA or an AI ISA, connect it to your CRM and calendar, and track speed to lead and appointments kept.
