What's the difference between an ISA and a buyer's agent?

A buyer's agent is a licensed agent who shows properties, writes offers, and represents clients in transactions. An ISA does the work that comes before that: calling new leads, qualifying intent, and booking appointments. The ISA hands the qualified appointment to the buyer's agent who then takes over.

How fast does an ISA need to call new leads?

Industry data is consistent across 20+ years of studies: leads contacted within 5 minutes of arrival convert at roughly 9x the rate of leads contacted at 30+ minutes. A great ISA calls within 1–3 minutes of lead arrival. A mediocre ISA calls within an hour. The gap is the difference between converting 8% of inbound leads and 1%.

How many leads can one ISA handle?

A full-time ISA can manage 200–400 active leads in nurture cadences and handle 30–60 fresh inbound leads per week. Past 60/week, response times degrade. Past 80, you need a second ISA or you're leaving conversions on the table.

How much does an ISA cost?

A US-based ISA typically runs $36K–$60K base salary plus appointment-set bonuses ($25–$75 per booked appointment). A full-time Philippines-based ISA through PHVA runs $1,000–$1,400/month all-in. Many teams add an appointment-set bonus to either model to align incentives.

What CRM does an ISA need?

The most common ISA CRMs in 2026 are Follow Up Boss, KvCORE, Sierra Interactive, BoomTown, and Lofty. The CRM matters less than the cadence discipline — an ISA running diligent 14-day touch sequences in any CRM will outperform an ISA running sloppy sequences in the most expensive one.

What is an ISA in Real Estate?

Last updated April 27, 2026

An ISA (Inside Sales Agent) is the person on a real estate team who calls and texts inbound leads within minutes, qualifies them, and books the appointment-ready ones onto a licensed agent's calendar.

The plain-English definition

An ISA — Inside Sales Agent — is a non-licensed (or sometimes licensed) team member whose entire job is the top of the funnel: catching inbound leads fast, qualifying them through a structured conversation, and converting the qualified ones into appointments on a licensed agent's calendar.

The role exists because licensed agents are the team's most expensive resource. An agent's hour is best spent in front of a client who's ready to buy or list — not on the phone with a Zillow lead who isn't sure if they want to move this year. An ISA is the filter that ensures only appointment-ready leads make it to the agent.

Done well, an ISA program turns a flat lead pipeline into a predictable appointment volume. Done poorly, it's just a person making calls who fails to convert. The difference is almost entirely about speed-to-lead, cadence discipline, and script quality — not about the ISA's personality.

The two ISA archetypes

1. Inbound ISA

Catches and qualifies leads that come in from your marketing — Zillow, Google PPC, Facebook lead ads, IDX-website forms, Open House sign-ins. The work is reactive but high-leverage: a 1-minute response time vs. a 30-minute response time can 5–10x conversion. Inbound ISAs typically work 200–400 active leads at a time and book 8–15 appointments per week.

2. Outbound ISA

Prospects from cold lists — expired listings, FSBOs, geographic farms, just-listed/just-sold neighborhoods. The work is proactive and harder; conversion rates are lower (1–3% to appointment), but volume can be massive. Outbound ISAs typically make 100–200 dials per day and book 3–6 appointments per week.

Most teams start with an inbound ISA because the leads are already warm and the ROI is fastest to prove. Outbound is usually a later expansion when inbound is consistently optimized.

What an ISA does in a typical day

First-touch dials (1–3 hours): every fresh inbound lead gets a call within 5 minutes of arrival, ideally within 1–2 minutes. If no answer, immediate text + voicemail. This is the single highest-leverage activity an ISA does all day.
Cadence follow-up (2–3 hours): working through the day's queued cadence touches — day-2 calls, day-5 texts, day-10 calls, day-14 emails. The cadence is the program; missing days breaks it.
Appointment confirmations (30–45 min): confirming tomorrow's appointments via text/call, sending the agent a brief summary of each lead before the meeting.
Long-term nurture review (45–60 min): weekly review of the 6–18 month nurture pile (people who'll buy/sell eventually but not now), light-touch follow-up to keep them in your orbit.
CRM hygiene (30–45 min): tagging leads correctly, logging notes, scheduling next touches, archiving dead leads. Without this, the cadence breaks down within 30 days.
Reporting (15–30 min): end-of-day update to the team lead with dials made, contacts reached, appointments set, no-shows.

The three KPIs that actually matter for ISAs

1. Speed to lead

Median time from lead arrival to first dial. Good: under 5 minutes. Great: under 2 minutes. Bad: anything over 30 minutes — you've already lost most of the conversion lift available.

2. Contact rate

Percentage of leads where the ISA reaches a live human within the first 14 days of cadence. Good: 35–45%. Great: 50–60%. Below 25%: cadence isn't being run. The cadence has to include calls, texts, and email at varied times of day.

3. Set rate (appointments / contacts)

Of the leads where contact is made, what percentage book an appointment. Good: 25–35%. Great: 40%+. This is where script quality and listening skill show up — you can train a 25% setter into a 40% setter with structured coaching, but only if the volume is there.

Common mistake: measuring an ISA on dials made instead of contacts reached. Dials are an input metric, not an output. An ISA who makes 200 dials/day to bad numbers and never reaches anyone is making no progress. The conversation count is the leading indicator that matters.

What separates a great ISA from a mediocre one

They make the first dial within 90 seconds. A great ISA has a workflow that gets them on the phone with a fresh lead before the lead has clicked away from your website.
They listen for two minutes before pitching anything. The qualifying conversation is the ISA's actual product. A mediocre ISA reads a script. A great ISA asks open questions and adapts.
They run the full 14-day cadence on every lead. No exceptions. The leads who convert often convert on touch 8 or 11 — not touch 1 or 2. Patience is the ISA's superpower.
They text in plain English. No emoji storms. No "Hi {first_name}!" tells. The text reads like a colleague, not a marketing system.
They confirm the appointment 18 hours before. Reduces no-show rate from ~30% to ~10%. A 10-second text saves the agent an hour of wasted time.

How ISAs are typically hired and paid

US-based hourly ISA: $20–$30/hour + $25–$50 per appointment-set bonus. Annual all-in: $50K–$80K.
US-based salaried ISA: $40K–$55K base + appointment bonuses. Annual all-in: $55K–$80K.
Philippines-based managed ISA (PHVA): $1,000–$1,400/month full-time. Annual all-in: $12K–$17K. Many teams add a per-appointment bonus on top to align incentives.
Per-appointment outsourced ISA service: $50–$150 per booked appointment, no monthly retainer. Useful for testing the model without the ongoing commitment, expensive at scale.

Frequently asked questions

Does an ISA need a real estate license?

In most states, no — if the ISA's role is limited to qualifying interest and booking appointments. The moment the conversation drifts into advising on offer terms, market value, or contract specifics, you're in licensed territory. Many teams structure scripts to keep the ISA inside the qualifying boundary and hand off to a licensed agent for everything else.

Can a Philippines-based ISA work US business hours?

Yes — most PHVA ISA placements work either US Central or US Eastern time, which means a 9–5 evening shift in their local Philippines time. This is normal and expected; the VAs we place have explicitly opted in to US-hours work.

Will US leads accept calls from a Philippines-based ISA?

If the ISA is using a US-based phone number (via your CRM, RingCentral, OpenPhone, etc.) and has clear English fluency, the lead has no way to know where the ISA is physically located. The accent is rarely an issue when the ISA has been pre-screened for English fluency, which Academy graduates have.

How long does it take to ramp a new ISA?

2–4 weeks to working productivity with a structured onboarding (script, cadence templates, role-play practice, supervised first 50 calls). Past month one, performance climbs steadily through month three as the ISA learns your specific market vocabulary, your product nuances, and the no-objection patterns of your specific lead sources.

Need an ISA dialing leads in 11 days?

PHVA places Academy-certified ISAs into US real estate teams. $1,000–$1,400/month full-time. Trained on Follow Up Boss / KvCORE cadences, the “5-minute rule” speed-to-lead, and US-style qualifying conversations.
