Algorithmic rent recommendations are built from market and portfolio data. The advertised range and vacancy pattern are the parts a tenant can actually observe and capture.
Several cities have restricted algorithmic rent-setting and litigation continues; in all cases a dated record of the offers is the starting point.
The protocol
- Photograph the current renewal offer and note its date.
- Record the building's advertised rents for comparable units each week while you decide.
- Note vacancy patterns — units that stay listed, price drops, and incentives offered.
- Ask the manager, in writing, how the increase was determined and whether pricing software was used.
- Keep everything, then decide whether to negotiate, complain, or move.
What the tool does
Build a rent offer-history record It runs locally in this browser and sends nothing.
Limit first: This is a record-keeping and comparison aid, not legal or financial advice. It cannot prove that a price was personalised, and it does not know what a company's pricing model does internally.

Cost: Free: one complete run in this browser, no account. Optional $4 one-time unlock allows unlimited runs of this tool on this browser. The free path and safety guidance never require payment.
Rule status (mixed route): Status, 2026-10-03: New York's algorithmic rent-setting ban is stayed by a federal injunction (S.D.N.Y., 2026-09-30); city and state rules differ and DOJ–RealPage litigation continues, so confirm the rule where the unit sits.
