What Redline catches
The traps in your lease,flagged in plain English.
Auto-renewal with a notice-window trap
Many leases auto-renew for another 12 months unless you give written notice 60–90 days before expiration. Miss the window by a day, you're locked in. Some states (Minnesota, New York) now require explicit disclosure of auto-renewal language — Redline flags whether your lease meets it.
Holdover rent at 150–200% of normal
Stay one day past the lease end without a renewal signed and the landlord can charge a holdover premium — typically 150% of monthly rent, sometimes 200%. The clause is usually two paragraphs deep in the term section.
Early-termination fees that double or triple
Move out for a job, a divorce, or a roommate change and the lease bills you 2–3 months' rent as a 'liquidated damages' fee. State law caps some of these. The clause is usually buried near the end and looks like boilerplate.
Repair-cost language that bluffs you
The implied warranty of habitability prevents a landlord from shifting HVAC, plumbing, heat, or pest repairs to you in most states. But many leases include the clause anyway — and most renters pay because they don't know it's unenforceable.
Security-deposit deductions you can't dispute
Some leases waive itemized deduction lists or set flat 'cleaning fees' regardless of condition. State law usually overrides — California (AB 2801) now requires before/after photos for damage claims — but the clause is designed to make you give up first.
Joint-and-several with roommates
If your roommate stops paying, the landlord can pursue you for the full rent — not just your half. The clause is one sentence in a 30-page document.
Landlord entry without proper notice
Most states require 24-48 hours' written notice before a landlord enters. Lease language saying the landlord can enter 'at reasonable times' or 'with no notice for inspection' usually conflicts with state statute, but the clause is in the document anyway.
Arbitration + class-action waivers
Modern corporate leases route disputes into binding arbitration and waive class-action rights. Most clauses preserve small-claims access — the real harm is being unable to join a tenant class action when a landlord overcharges 800 units the same way.
How to use Redline on a lease
Before. After. When something goes wrong.
Before signing
Photograph or paste the lease. Redline returns a risk score and a list of clauses to push back on. Bring it to the leasing office — most pushback works because landlords expect renters not to ask.
After signing
Scan it anyway. Knowing what's actually in your lease helps with repair requests, deposit timing, and the renewal conversation a year later. The clauses don't change — your awareness does.
When something goes wrong
Landlord shows up unannounced, charges a fee that wasn't in the original lease, refuses a repair. Re-scan the relevant section to know whether the clause is enforceable or whether they're bluffing.
At renewal
Landlords change terms at renewal. Auto-renewal language, fee schedules, and carve-outs often shift. Re-scan the renewal before you initial it.

Common lease-scan questions.
Is Redline a substitute for a real estate attorney?+
No. Redline is an AI tool that flags risky clauses and explains lease language in plain English. For high-stakes decisions — disputes, eviction notices, or anything involving more than one month's rent on the line — talk to a tenants' rights attorney or your local housing aid office.
Can I scan a lease I've already signed?+
Yes. Most renters do. Knowing what's in the lease is useful even after you sign — for repair-request strategy, security-deposit timing, renewal negotiation, and knowing when the landlord is actually allowed to charge a fee versus when they're bluffing.
What lease clauses does Redline flag?+
Auto-renewal notice windows, holdover rent multipliers, early-termination fees, security-deposit deductions, repair-cost language that conflicts with the implied warranty of habitability, late-fee stacks, attorney-fee provisions, arbitration and class-action waivers, joint-and-several language for roommates, landlord entry-notice provisions, and the custom clauses landlords add that don't appear in standard form leases.
Does Redline work on PDF leases from my landlord's portal?+
Yes. Upload the PDF directly, paste the text from a portal, or photograph a printed copy at the leasing office. Redline auto-detects the document type and runs the same scan on all three.
How much does it cost?+
$1 per scan on the Pack tier (5 scans for $9.99). Plus is $29.99/year for 30 scans. Pro is $89.99/year unlimited. Most renters review one lease per year and pay $1 once.
Is my lease private?+
