Listing Analyzer.

Paste a Zillow, Redfin, or Realtor URL. The Listing Analyzer pulls the home's details, runs a Reality Check, and explains the gap between the advertised payment and what you'll actually pay.

What it does.

The Listing Analyzer automates the input step on the Listing Reality Check. Today, the Reality Check requires you to enter the home price, the listing's payment estimate, and a few other details by hand. The Analyzer extracts those from a URL and runs the math in one step.

The output is identical to running the Reality Check manually — the AI doesn't generate numbers, it pulls inputs and runs the calculator.

Pulled the listing. 2,140 sq ft single-family in Frisco, listed at $525,000, listing-estimated payment $2,950. HOA $385/mo. Built 2014. Last sold 2018 for $385,000.
Reality Check at 20% down, 6.75% rate: True monthly cost lands around $3,890 — about $940 above the listing's estimate. The big drivers: post-purchase tax reassessment adds ~$210/mo (the prior owner was assessed at $385K), maintenance reserve adds $437/mo (1% of value), and HOA at $385 wasn't in the listing estimate.
Want me to (a) run this at 10% down with PMI, (b) compare it to a $475K listing 0.4 miles away, or (c) show the underlying line items in detail?
Underlying tool

The math runs in the Listing Reality Check.

This AI tool sits on top of a real calculator. The numbers it shows you come from deterministic math, not from a language model's pattern matching. While the AI version is in development, the underlying calculator is fully live — you can run the same math today by clicking through.
