How Much Does a Real Estate ISA Cost in 2026?

A real estate ISA (inside sales agent) costs between $44,000 and $65,000 a year in-house once you add bonuses and payroll costs, or $1,800 to $3,000 a month if you outsource to a virtual ISA service. That is the going rate for a person who answers your leads, follows up, and books appointments. Sifta does the answering and the chasing by text for $199 a month, and it already knows your deals because it reads your email and client threads. This page lays out the real numbers so you can decide.

The ISA math looks fine on a spreadsheet and hurts in real life. ZipRecruiter puts the average ISA base salary at $44,158 a year as of August 29, 2026, with most between $39,000 and $49,500. Add commission bonuses, payroll tax, software seats and the two months it takes to train them, and NurtureOS estimates a fully loaded in-house ISA at $4,583 to $5,417 a month, or $6,250 to $7,083 in year one. Outsourced virtual ISA services run $720 to $3,000 a month for part-time hours, and full-time services start around $1,988 a month, often on a 12-month contract. For a solo agent closing the national median of nine sides a year, that is one to two full commissions spent before the ISA books a single appointment. And an ISA works a shift. Your leads come in at 9:40pm on a Sunday.

Sound Familiar?

You are paying $2,000 to $5,000 a month for a person to do the first ten minutes of every lead, and then you take over anyway because they do not know the client.

Training an ISA takes weeks. Turnover in the role is high. Every time one leaves, you start over with someone who has never heard of your lenders, your listings or your past clients.

An ISA works business hours. Zillow, Realtor.com and your website do not. The lead that lands at 9:40pm gets answered at 9:00am, by which time two other agents have called.

Outsourced ISA contracts lock you in for a year and bill the same whether they booked eight appointments or zero.

How Sifta Fixes This

✓

Sifta answers leads within seconds, any hour, with the reply already written in your voice. You say send, or let Sifta send it. There is no shift and no training period, because Sifta reads your email and client texts and knows your deals from the first day.

✓

Sifta does the follow-up an ISA is supposed to do and usually does not: it keeps the list, nudges the lead who went quiet, chases the lender for docs, and tells you when someone answers. Six touches happen because Sifta does not forget the fourth one.

✓

Sifta remembers what every client said, so the handoff problem disappears. There is no handoff. The same worker that answered the lead remembers the budget, the school district and the kid's name when you ask three weeks later.

✓

What Sifta does not do: make phone calls. If your ISA's value is dialing, keep the dialer. Most agents find the texting, the email, the follow-up and the memory were the expensive part.

What You Get
