What Is Inside Sales Agent (ISA)?

The ISA role became standard on larger real estate teams as a way to separate lead conversion from lead generation. Instead of an outside agent chasing every inbound sign call, portal lead, or past-client referral personally, the ISA works the phones, texts, and CRM to qualify interest and set the appointment, then hands a ready buyer or seller conversation to the agent who closes it.

Compensation for the role typically runs a base salary plus a smaller commission share, rather than commission only, since ISAs spend most of the day on structured inbound and outbound follow-up rather than closing deals themselves. Industry salary data collected by ZipRecruiter puts the national average in-house ISA base salary at roughly $44,000 a year, before commission. Virtual or outsourced ISA services are commonly priced differently: REVAS.us, a company that provides virtual ISA services, prices its offering at $18 to $25 an hour, or roughly $800 to $3,000 or more a month depending on lead volume and hours covered.

The ISA role and VA Horizon's model solve different problems. An ISA works leads a team already generated: portal inquiries, sign calls, past clients, sphere referrals. VA Horizon runs the opposite direction: outbound cold calling to property owners who have not raised a hand yet, built specifically for wholesalers and investors sourcing off-market deals rather than listing agents converting inbound buyer and seller leads.
