This skill is platform-agnostic. The qualification logic, document requirements, and output formats apply equally across:
Tell the assistant which platform and jurisdiction you are working in if you want platform-specific field names or submission format.
"Salaried borrower, $95K income, $450 car payment, $700 student loan,
buying at $580K with 10% down in Ontario. Rate 5.49% 5yr fixed at TD."
"Self-employed borrower, 2yr NOA average $87K, no consumer debt,
purchase at $750K with 20% down in BC. Which A-lenders will look at this?"
"Draft a conditional approval email. Client got approved with 3 conditions:
employment letter, updated bank statements, and appraisal."
"Flag any expired or missing documents in this file:
pay stub from 45 days ago, employment letter from 60 days ago,
NOA 2022 only (missing 2023), bank statements 95 days old."
