What it’s good for

Several deals at once

Put a few deals in one message. The assistant checks each deal and lines up the results.

“Check these three: a CA purchase, a TX DSCR cash-out and a FL 2-unit.”

What-ifs without retyping

Change one number. It checks again and keeps everything else.

“What if the loan amount was $390,000?”

It asks what's missing

If a detail is missing or unclear, the assistant asks you or checks each option and shows both.

“Are the 12-month bank statements personal or business?”

Check the numbers your assistant used before you rely on an answer.
