Lender Scenario Comparison Agent

Show the client the best qualifying loan options with true costs

Lender Scenario Comparison Agent: what goes in, what the agent does and what you get

What it does

Clients want to know which loan is best for them, not just which has the lowest rate. This agent takes the borrower's profile and goals, pulls each lender's guidelines and current rate sheets, and builds scenarios per lender and product. It checks each scenario against the lender's rules on credit score, loan-to-value, debt-to-income and property type, and drops those the borrower does not qualify for. When debt-to-income is within 2 points of a limit, it tests whether paying off a small debt opens more options. For the remaining scenarios it calculates monthly payment, cash to close and total cost over the client's expected time in the home, showing points and credits clearly. It drafts a plain comparison of the top three. The broker reviews and makes the recommendation. Edge case: a borrower near a DTI limit sees how a small payoff changes options.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

An example run

What happensA borrower at 45.8% debt-to-income failed the rules check for two lenders with a 45% cap. The agent tested paying off a $2,100 card balance, which brought DTI to 44.2% and opened both. Over a seven-year expected stay, the best option saved about $9,400 versus the lowest rate with points. The broker reviewed the comparison and recommended it.
