AI answers the new lead in 90 seconds, or a human answers it in three hours. Which do you build?

Running about 260 to 310 inbound seller leads a month across paid search and direct mail, two acquisitions people, no dedicated ISA. Measured speed to lead over six weeks and the median was 2 hours 50 minutes, with the tail going overnight on anything after 6pm. Roughly a third of leads never got a first response inside 24 hours.

Quote in front of me builds an AI first-touch layer. Inbound lead gets a conversational text inside 90 seconds, qualifies on motivation, timeline and condition, books straight into a calendar, hands off to a human on any answer it can't classify. Build is mid five figures plus per-message cost and a monthly.

The case against isn't cost. It's that the first ninety seconds is the only moment a seller is actually paying attention, and spending it on a bot that opens with something generic burns the one good touch you get. My better acquisitions person closes sellers on the first call by sounding like a person who has bought houses. An AI that books an appointment with a seller who then feels handled by a robot may be a worse appointment.

There's also a real compliance layer here. Consent and messaging rules for automated texting vary and change, and that's a conversation for counsel, not a forum.

So the assumption the whole build rests on: is a 90 second generic response worth more than a 3 hour good one? I have no idea, and my gut is unreliable here because it keeps arguing for the human I like.
