Doormeter

Returns whether DoorMeter (the Chrome extension) is connected, the pairing code to show the user when it asks for one, the plan, versions and how many deals and profiles are saved. Call this first.

Takes no parameters.

Returns the user's saved deals, newest first, one line each: address, price, latest price drop, score (0–100), monthly cash flow, cash-on-cash and cap rate (fractions), or for live-in the monthly cost and budget gap, plus status and, when numbers can't be computed, why, and the profile they were computed with. "total" counts all matches before the limit.

Returns one saved deal in full: the page's facts, the user's edits, every computed number, price history and notes.

Returns the user's assumption profiles (loan, expenses, targets and per-strategy settings) and which one is active.

Takes no parameters.

Computes a saved deal again with changes (a what-if) and returns the numbers before and after. Nothing is saved.

Computes the numbers for a home that isn't saved, from the inputs given, with DoorMeter's ZIP-based rent, tax and insurance estimates for anything left out. Returns the numbers, or what is missing to compute them.

Opens a Zillow or Redfin search in a new, visible tab in the user's Chrome and waits (up to 20 s) until DoorMeter has read its homes. Give a search "url", or "site" and a five-digit "zip" with optional price and bed limits. Redfin applies the limits to the search itself; Zillow's search opens without them, so pass the same minPrice, maxPrice and minBeds to search_results. Returns the tab id and how many homes it has. Then call search_results. Calling it again opens another tab.

Returns every home on an open Zillow or Redfin search tab (the one open_search opened, else the one the user used last), computed with the user's own profile exactly like DoorMeter's search badges: link, address, price, beds, days on market, whether it's new to the user (never opened or saved), score (0–100), cash flow, cash-on-cash and cap rate, or why it can't be computed from the search page. Best score first; "total" counts all matches before the limit.

Opens a Zillow or Redfin listing in a visible tab, reads it exactly like DoorMeter's card (the listing's own HOA, tax, rent and value estimates), computes its numbers with the user's profile (and their saved edits if they saved it), then closes the tab unless keepOpen. Tabs open one at a time, a few seconds apart, without taking focus. Reading a listing counts it as opened (it no longer shows as new in search_results). Use it for homes search_results couldn't compute.

Computes the highest price that still meets the user's own targets, like the Offer tab on DoorMeter's card: for buy-and-hold per target (cash-on-cash, cash flow, DSCR); house-hack and brrrr likewise; for live-in a suggested range and the most their budget allows. For a saved deal ("key", with optional "changes" like analyze_deal) or a listing "url".

Saves a Zillow or Redfin listing to the user's DoorMeter deals, exactly as the card's Save button does (read from its page in a tab, with the active profile), optionally with a first note. Saving a home that is already saved refreshes its page facts and keeps its notes, status, the user's edits, profile and strategy (unless "strategy" is given).

Changes a saved deal's status (watching, offer = offer made, passed) and/or its notes: "appendNote" adds a line; "notes" replaces all of the user's notes, so prefer appendNote unless they asked to rewrite them. It never deletes a deal.
