The more I read about this, the more it plays out like Game of Thrones. This is about to get bloody. RealPage froze all new EliseAI activations. No new communities, no in-flight rollouts, even with a signed order. Existing properties keep running. RealPage says it's reviewing whether Elise broke its API terms. Elise says it didn't. RealPage is House Lannister, the richest family in the story and the one holding the throne. Here, that means 20 million units of operational data, plus its own leasing agent, Knock. EliseAI is Daenerys, the outsider who shows up with ambition and dragons. Elise has a $4 billion valuation and a dragon named Apollo. Yardi is the Wall, the giant ice wall every traveler has to cross. A vendor needs two years in business, three mutual clients, and a license fee per interface, cited near $25,000 a year. Entrata runs the toll bridge. One integration vendor's docs list $25,000 for a sandbox and $60,000 for webhooks. It's crazy, I know. AppFolio is the Tyrells, the friendly house that opens its gates and feeds you at its own table. Its Claude connector hands jobs to AppFolio's own agent instead of handing raw data to yours. Governed, which is fair. Also the vendors menu. CoStar is the Iron Bank, the lender that guards its vault and always collects. It has sued over alleged scraping. We are the smallfolk, the regular people who pay for every war. Propertyware, RealPages single-family platform, charges the customer $1 per unit per month to turn on API access, per Supergood. On 10,000 units, that's $120,000 a year. These new invaders don't need the old gates. A property manager with a few thousand units told Brad Hargreaves he built his own Claude Code tooling that pulls data out of AppFolio and takes actions the vendor wouldn't allow. Companies already sell unofficial Entrata and Propertyware APIs built by driving the login screen as a person would. Even Daenerys has a wall. Apollo only works inside Elise. An agent that drives a screen works for whoever pays the bill. Before your next renewal, get three things in writing: who owns your data, what it costs to connect a tool you already pay for, and whether the vendor can block that tool at a new property. In the show, the houses fight over the throne while the real threat marches in from the north. The warning line is Winter is coming. I wonder if all these PMS companies realize winter's coming for them all.
