Deal Auditor

Pull key listing numbers, quote the source text, and score the deal.

What you give it
A property link or pasted text with your loan rate and down payment
What you get back
A structured property audit table with quoted proofs and a deal verdict
Cost
6 credits a run. Partly answered: 1 credit. Nothing found: free. (~$0.35 a run)

How it works

  1. 1.Crawl the property URL or read the submitted listing text
  2. 2.Extract asking price, beds, baths, sq ft, lot, year, and taxes
  3. 3.Match every extracted figure to an exact line quote from the page
  4. 4.Mark any unlisted fee, tax, or spec explicitly as not listed
  5. 5.Compute monthly payment and grade value against your target price
  6. 6.Log extraction misses to improve future listing parsing checks

Rules it follows

  • Never invent missing numbers, taxes, HOA fees, or links; label missing items as not listed.
  • State plainly and immediately whenever a listing link is unreadable, blocked, or broken.
  • Require an exact verbatim line quote for every extracted statistic and price.
  • Use remembered patterns only to guide searches; freshly crawled facts always take priority.
  • Use memory as a guide, never as proof; fresh retrieved facts beat remembered facts.
  • Do not store secrets, private contact details, payment data, or login material in memory.
