Underwrite any listing in under a minute.

A serious underwrite takes a competent analyst four to eight hours per deal. Most agents skip it, and most first-time investor clients never ask for one. They read the listing sheet, drive by the block, and make an offer on gut feel.

That worked when rates sat near zero and prices only moved one direction. It stopped working the day the Fed started hiking, and it has not started working again since. The agents who win investor clients now are the ones who can hand over a real model, not just a listing link.

Before this generation of AI agents, the alternative was a half day building the model yourself, or paying an analyst a few hundred dollars per deal. Now one prompt produces the model, the debt schedule, the ten-year cash flow, and the sensitivities in about sixty seconds, with your name on the work.

Open a new Co-Work chat and use the prompt below on the next listing you or your client are seriously considering. The Model Builder agent asks four or five clarifying questions before it starts. Answer them; the ones you can't answer yet are the ones worth researching before an offer goes in.

The first listing run through this stack was a four-unit multifamily asking $1.85M, roughly nine percent under the block's recent comps. Standard conventional financing, seventy-five percent LTV, five-year hold.

The first model came back fast: an 18% Year 1 cash-on-cash return. That number looked too good to hand to a client. Before it could be flagged, Claude caught the inconsistency itself, mid-output.

That sequence, an agent catching its own bug and re-verifying before handing off the answer, is the difference between a tool and something you can actually put your name behind in front of a client.
