Every lead answered. Every showing booked. Without the hire.
International ISA is the inside sales and back-office team for real estate agents, teams, and brokerages — lead follow-up, appointment setting, listing admin, and transaction paperwork from $18/hour, so you spend your hours closing, not chasing.
15 minutes, no commitment — we'll tell you honestly if we're not the right fit.
What We Do
International ISA provides inside sales and back-office support built exclusively for real estate — solo agents scaling past their sphere, team leaders feeding a roster of agents, and brokerages that need every lead worked without the overhead of hiring in-house.
Because real estate is all we do, your ISA already speaks the language — listings and lockboxes, CMAs and contingencies, sign calls and sphere follow-up. No translation required.
Lead Follow-Up & Qualification
Online leads, sign calls, open-house lists, and sphere — called, qualified, and nurtured until they're ready to meet you.
Appointment Setting & CRM Care
Showings and listing appointments on your calendar, and your CRM (Follow Up Boss, KW Command, Sierra, or any other) kept clean and current.
Listing Management
Listing details, status changes, photos, and client-facing updates kept accurate from live to closed.
Transaction Support
Contract-to-close paperwork chased and tracked — signatures, deadlines, and documents that never stall a closing.
Documentation & Compliance
Files complete, disclosures collected, and paperwork organized the way your broker wants it.
Client Care
Buyers and sellers get a professional, responsive point of contact at every step — your reviews will show it.
You take the appointments. We take the phones.
Follow-up, scheduling, and admin — off your plate. More conversations, more appointments, more closings, without adding headcount.
Save 15+ Hours a Week
Get back the hours you lose to follow-up calls and paperwork — and spend them at appointments.
Real Estate–Trained ISAs
Professionals who know the difference between a lead and a listing appointment — bilingual (EN/ES) support available if your market needs it.
Scale Without Hiring
Add capacity on demand — no payroll, benefits, or training overhead.
Increase Your GCI
Consistent, professional follow-up means fewer leads — and fewer commissions — slip through the cracks.
Focus on Closing
Spend your time face-to-face with buyers and sellers, not chasing voicemail.

Built for ambitious agents and teams
Whether you're a solo agent scaling past your sphere, a team leader feeding twenty agents, or a brokerage protecting its lead spend, International ISA gives you follow-up capacity to match your ambition.
Simple, Transparent Pricing
An in-house ISA or assistant costs $45,000+ a year once payroll, benefits, and training are counted. An International ISA agent covers the same desk for $18/hour — starting around $1,560/month at 20 hours a week, month-to-month, cancel anytime.
$18/hour, flat
No payroll taxes, no benefits, no equipment, no recruiting fees. The rate on this page is the rate you pay.
Month-to-month
No long contracts. If we're not earning our keep, you walk — that's on us to prevent.
Founder-led service
You deal directly with the founder, not an account queue. Questions get answered within one business day.
Honest by Default
We're a newly launched company, so you won't find fake five-star reviews here. What you'll find instead: transparent pricing, a founder who picks up the phone, and a free consultation where we'll tell you plainly whether we can help. Real client stories will appear here as our first partners see results — and we'll gladly connect you with references as they come.
Frequently Asked Questions
What does an inside sales agent (ISA) do?
An ISA handles the sales conversations that eat your day: calling and qualifying new leads, following up until they're ready, setting appointments on your calendar, and keeping your CRM clean. You show up to booked appointments instead of chasing cold lists.
How much does it cost?
$18/hour with a 20-hour weekly minimum — about $1,560/month. Compare that to $45,000+ a year for an in-house hire doing the same work.
Do you only work with real estate?
Yes — real estate is all we do: agents, teams, brokerages, and property managers. Specializing means your ISA shows up already fluent in listings, showings, contingencies, and closing timelines instead of learning your world on your dime.
Is support available in Spanish?
Yes — our agents work English-first, and bilingual English/Spanish support is included at no extra charge when your market needs it.
How fast can we start?
Days, not months. After the consultation we onboard your ISA on your CRM and scripts, and calls start going out the same week.
