    Description, as the server wrote it
    Compute the standard NWMLS transaction deadline set from a mutual-acceptance date: earnest money (Form 21), seller disclosure delivery + buyer rescission (Form 17, RCW 64.06), title contingency (Form 22T), inspection (Form 35), financing (Form 22A), and FIRPTA certification (Form 22E). Business-day counts exclude weekends and Washington state holidays per RCW 1.16.050 — never plain calendar arithmetic. Washington/NWMLS transactions only. Dates are the standard form DEFAULTS computed from public rules (no NWMLS data or form text); the result flags dates landing on non-business days and includes a verify-against-the-executed-contract disclaimer that must accompany any advice built on these dates. The result includes an 'attributions' array (upstream source lines and the NWMLS/DOR/county non-affiliation line) and a professional-advice disclaimer — pass both through to end users.

    Description, as the server wrote it
    Estimate a Washington home seller's net proceeds: commission, graduated REET, title/escrow/closing costs, mortgage payoff, and optional HOA/tax prorations — every line item computed deterministically by the same engine SENTINEL's product uses. Use for 'what will the seller walk away with' questions on WA sales; WA counties only. The result is an itemized dict. Uses no third-party data. The result includes an 'attributions' array (upstream source lines and the NWMLS/DOR/county non-affiliation line) and a professional-advice disclaimer — pass both through to end users.

    Description, as the server wrote it
    Calculate Washington State Real Estate Excise Tax (REET, RCW 82.45) for one sale: graduated state brackets plus the county's local rate, computed deterministically by SENTINEL's production engine — never estimated. Use when you need the exact excise tax owed on a WA home sale (seller-paid by default). Washington State counties only. The result includes the per-bracket breakdown, the $5 DOR technology fee, and rate-assumption caveats (verify the DOR location code for city-level exceptions). Uses no third-party data. The result includes an 'attributions' array (upstream source lines and the NWMLS/DOR/county non-affiliation line) and a professional-advice disclaimer — pass both through to end users.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
