The lease, from first draft to signed.
TenantBinder is an app for iPhone and Android where a landlord writes a rental agreement, the tenant reads it and asks for changes, and both sides sign it electronically. The rules of the state the property is in are checked while the lease is being written, not after.
Writing a lease is free. A tenant is never asked to pay for anything.
Three moves, and the lease is done.
Write it
Pick the terms you want from a catalog — rent, deposit, pets, utilities, repairs. Each one is a small form, not a blank page. Your state's caps and required disclosures are applied as you go.
Agree on it
Send the tenant an invite link. They read every term, ask for changes in plain words, and give their OK. Nothing moves on until they do.
Sign it
Each signer confirms a code by email and then one by text, draws their signature, and signs in turn. Everyone gets the finished PDF and its certificate.
The state rule appears while the term is still being written.
Deposit caps, entry-notice periods, late-fee limits and rent caps are checked against the place the property is in, and the statute is named on the same line. Disclosures the state requires attach themselves — California's rent-cap addendum, the bed-bug notice, the domestic-violence rights notice, Megan's Law.
The rules are data, not code. When a state changes a cap, the change reaches you without waiting for an app release.
51 places carry their own rulebook: all 50 states and the District of Columbia.
A tenant can ask for a change in plain language.
The tenant writes what they want changed in their own words, on the term itself. You answer by changing the term or by saying no, and the request stands on the record as open, applied or declined.
An OK is given against one version of the lease. Edit a term afterwards and that OK stops counting — the tenant is asked again, and the app can show them exactly what moved.
"We agreed $1,850 at the viewing, the listing said $1,850 too. Can we go back to that?"
A finished lease comes with its own proof.
Before anyone can sign, a code goes to their email and then a second one to their phone by text. They draw their signature, and it is stamped into the page they are looking at. Finished pages are flattened to an image, so nobody can lift a signature back out of the file.
Four independent timestamp authorities are asked to stamp every finished document, and the completion certificate names each one that answered — along with who signed what, when, and from where.
The signed lease is the beginning, not the filing cabinet.
Documents stay with the agreement.
The signed lease and its disclosures file themselves the moment signing finishes. Everything the tenancy collects afterwards goes to the same place, under headings that already exist, where both sides can reach it.
- Move-in photos, meter readings and the deposit receipt.
- Monthly bills, notices and repair records, filed by month.
- Either side can ask the other for a document, and see whether it arrived.
Rent follows the lease.
Signing draws the rent schedule from the lease's own terms. The tenant marks a payment as made, the landlord confirms it, and the running total is only ever the confirmed one.
Every change stays in history.
Versions, approvals, change requests and signatures are written to a history the database keeps itself. A push and an email say when something needs you.
Built for residential leases, and honest about the money.
- Rent stays between you and your tenant. TenantBinder keeps the schedule and the record of what was paid, and does not hold, move or take a cut of the money — which is why there is nothing to reconcile at the end of a tenancy.
- It is tooling you drive yourself: it applies your state's caps, names the statute it applied, and attaches the disclosures the state requires. It is document tooling rather than a law firm, and a lawyer is still a lawyer.
A lease both sides can follow.
If a landlord sent you an invite link, open it — the portal does the rest, in your browser, with nothing to install. If you already have an account, the portal is where your documents are. Landlords write leases in the app: the store listings are still on their way, so write to us and we will get you started today.
Coming soon — neither listing is live yet.
