Most people sign a lease without reading every clause — because who has a lawyer on call? TheLeaseCheck reads it for you in 60 seconds: a 0–100 tenant-friendliness score, every red flag ranked by severity with the exact clause quoted, a chat that answers "can my rent go up mid-lease?" in plain English, and — new — a ready-to-send negotiation letter that turns what it finds into something you can actually act on. First lease free, no card required. All 50 states.
