How to Write a Lease Agreement: A Practical Guide for New Landlords

This is not legal advice. Landlord-tenant law is set state by state and often city by city, and it changes. Whatever lease you end up using — a template, an association form, one drafted here, or one generated by AI — have a real estate attorney licensed in the property's state read it before you sign it or hand it to a tenant. What follows is how to think about a lease and what belongs in one, not a substitute for that review.

The first lease I ever used was handed to me by another property investor. That's how most landlords get their first one — somebody who's been doing it longer passes along the document they've been using, and you change the names and the numbers. It was a reasonable starting point, and it was written for their property, not mine.

A lease is not paperwork you produce because you're supposed to. It's the document you'll be reading, line by line, on the one day something goes wrong — a deposit you need to withhold from, a tenant who won't leave, a repair bill you don't think is yours. Everything below is written with that day in mind.

Why You Need One, Even for a Room

In most states a verbal tenancy is perfectly legal. You can shake hands, take rent, and have a binding agreement. The problem isn't legality — it's evidence.

Without a written lease you have no agreed rent due date, no enforceable late fee, no deposit terms, no entry notice, no pet policy, and no record of what the property looked like the day the tenant moved in. In a dispute, a court has almost nothing to work with, and ambiguity in a rental agreement is usually resolved against the landlord who drafted it — or who failed to.

Three specific things go wrong without one:

• You can't charge what you never agreed. A late fee is a contract term. If it isn't in a signed lease, you can't impose it, and you can't add it mid-tenancy without the tenant agreeing.
• You can't prove condition. Deposit deductions rest on the difference between move-in and move-out condition. No move-in record, no deduction you can defend.
• You may be non-compliant regardless. Federal lead-paint disclosure applies to most pre-1978 housing whether or not you use a lease, and many states add their own mandatory disclosures.

I've also inherited the opposite problem: a unit that came with an agency-managed tenancy where no deposit had ever been recorded against the lease. Nobody had done anything wrong, exactly — but when that tenancy ended there was no document that said what was held, so there was nothing to return and nothing to withhold. The lease is where that fact is supposed to live.

Fixed Term, Month-to-Month, or Room Rental

Three structures cover nearly everything a small landlord does.

	How it works	Best for
Fixed term	Runs for a set period, usually 12 months. Neither party can end it early without cause or agreement.	Stability. Most single-family and small multifamily lets.
Month-to-month	Rolls monthly until either side gives notice — typically 30 days, but set by state law.	Uncertainty: a property you may sell, a tenant on probation, a seasonal market.
Room rental	One tenant takes a room in a shared property; common areas are shared and defined in the agreement.	House shares, where tenants come and go independently.

The detail most new landlords miss is what happens when a fixed term ends. In most states, if the tenant stays and you keep taking rent, the tenancy automatically converts to month-to-month on the same terms. That's fine if you intended it. It's a problem if you assumed the tenancy simply stopped — because now you need to give statutory notice to end something you thought had already ended.

Say so explicitly in the term clause: what the end date is, whether it converts, and how much notice either party must give.

The Sections That Actually Matter

A complete residential lease runs to a dozen or so numbered sections. These are the ones that earn their place:

1. Parties and premises. Full legal names of every adult tenant, the property address, and — easy to forget — what comes with it. List the appliances, the parking space, the storage. Name any occupants who aren't signing, such as children, and state that nobody else may occupy the property without written consent.

2. Term. Start and end dates, proration for a partial month, and what happens at expiry.

3. Rent. The amount, the due day, and how it's paid. Separate base rent from pet rent if you charge it. State the grace period and the late fee — both the amount and the fact that it's a reasonable estimate of your administrative cost, not a penalty, which is the standard courts apply. Add a returned-payment fee and a rent-increase clause for any renewal period. See our state-by-state guide to rent late fees before you pick a number.

4. Security deposit. The amount, the statutory cap it sits under, what it may be applied to, the return deadline, and the tenant's right to be present at the move-out inspection. Deadlines vary widely — the security deposit return deadlines by state run from 14 to 60 days.

5. Use and occupancy. Residential use only, maximum occupancy, subletting, pets, smoking.

6. Maintenance and repairs. Split it explicitly. Landlord: habitability, structure, systems, supplied appliances. Tenant: cleanliness, prompt written notice of problems, smoke-detector batteries, filters, and — write this down — lawn and snow where applicable. Include the tenant's repair-and-deduct remedy and its preconditions, because your state grants it whether or not your lease mentions it.

7. Entry. The notice period, the permitted reasons, the exception for emergencies, and that locks may not be changed without giving you a key.

8. Default and remedies. What counts as default, the cure period for each type of breach, and the notice you must give. These periods are set by statute — in Missouri, for instance, non-payment and other breaches carry different notice requirements — so get them from your state's landlord-tenant act rather than from a template written for somewhere else.

9. Disclosures. Lead-based paint for pre-1978 buildings, plus whatever your state requires: methamphetamine contamination, bed bugs, mold, flood history, the landlord's name and address for notices.

10. Signatures. A block for you and a separate block for each tenant. Leave real space above the signature line — a surprising number of templates put the date on the line below and leave no room to actually sign.

How a New Investor Actually Produces One

Six realistic routes, in rough order of cost:

1. A lease handed to you by another landlord. Free, and how most people start. It's been used in the real world, which counts for something — but it was written for their property, their state and their situation, and it carries their omissions along with their experience. Read it as a draft, not a document.
2. An attorney drafts it. The gold standard, and the right call for your first lease in a new state. Expect a few hundred dollars, and ask for a version you can reuse.
3. A state landlord or apartment association form. Usually inexpensive, written for your state's law, and widely accepted. Generic about anything specific to your property, but a solid base.
4. A REALTOR® association form — with a catch. Most state REALTOR® associations publish a residential lease, and it's what you'll see agents using. They are generally members-only, and using one you aren't entitled to use can backfire: the Texas form (TXR-2001) is restricted to Texas REALTORS® members, and under its own terms a lease is voidable at will by the tenant if no REALTOR® member or Texas attorney negotiated it. Worth knowing that these are association forms, not state ones — real estate commissions approve sales contracts, and Colorado's commission states outright that there are no commission-approved leases.
5. A generic online template. Cheap and fast, and the most common source of the problems in this article — silent on local ordinances, often written for a different state entirely.
6. Generate a state-aware draft, then have it reviewed. This is what we built into PacRent: you give it the property, the term, the money and the tenants, and it drafts a complete agreement for your state and city — then you take it to an attorney the first time.

Whichever route you take, collect this before you start: every adult tenant's legal name and contact details, any non-signing occupants, the term dates, rent and due day, deposit and pet deposit, late fee and grace period, what's included with the unit, and which disclosures your state requires.

Signing It

Electronic signatures are valid for residential leases across the US under the federal E-SIGN Act and state equivalents. What matters is that each signer is identified, agrees to sign electronically, and gets a copy.

Two practical points. Get the lease signed before move-in, not during — a tenant with the keys has no reason to hurry. And on a joint tenancy, send it to every tenant at once rather than passing it along a chain; co-tenants are jointly liable and the document isn't executed until all of them have signed.

The weak point in any e-signature is identity: a signature block proves somebody clicked, not that the right person did. For a lease you may one day need to enforce against a named individual, that gap matters. In PacRent you can require identity verification through Stripe on a lease — the tenant confirms who they are against a government ID before the document will accept their signature, and the verification is recorded alongside the signing audit trail. It's set per lease — but decide your policy once and apply it to everyone. Requiring ID from some applicants and not others is the pattern fair-housing complaints are built on, and it's a bigger risk than the fraud you were guarding against. Verifying identity is permitted everywhere, including under California's strict rule; what's restricted is asking about immigration or citizenship status, which is a different question and not one you need answered.

New Lease Versus Renewal

This is the part that trips people up, and it's worth being precise about.

A renewal is not a new tenancy. The same people are staying in the same property, and three clauses have to reflect that or the document contradicts itself:

• Rent continues uninterrupted. No new first month's rent is due at signing. The tenant has been paying monthly throughout and simply carries on; the next payment falls due on the first of the month after the renewal starts.
• The deposit carries forward. You already hold it. Say so — the amount, that it was paid under the prior agreement, that it transfers on the same terms, and that no additional deposit is due. Refunding it and re-collecting it achieves nothing except moving money twice and creating a return deadline you then have to meet.
• No new move-in occurs. The checklist completed at the start of the original tenancy remains the agreed record of condition, and the baseline against which damage is assessed when the tenant eventually leaves. A renewal that silently creates a fresh baseline erases every bit of wear you'd documented.

Everything else — the appliance list, the occupants, the maintenance split, the exhibits — should carry across unchanged. The practical test: put the old lease and the renewal side by side, and the only differences should be the dates, the money, and those three clauses.

Attachments carry forward too. If the original lease referenced a certificate of compliance, a lead-paint disclosure and a move-in checklist, the renewal references the same documents and should have copies attached to it.

This is the part PacRent handles differently from a template. Rather than drafting a renewal from scratch, it amends the lease already in force — your own wording, your clause numbering, the appliance list you wrote three years ago — and changes only what a renewal requires. It carries the exhibits across onto the new lease, and then shows you a side-by-side comparison against the old document: what was reworded, what's new, and what was dropped. That last one is the useful part. A clause that quietly disappeared is invisible when you're reading the new lease on its own, and it's exactly the kind of thing that only surfaces years later when you need the clause that isn't there.

State Rules Decide Whether Your Clauses Hold

A lease is a contract, but it sits underneath landlord-tenant law — and where they conflict, the statute wins. A clause that exceeds a statutory cap is void even with the tenant's signature.

The rules that vary most:

What varies	Why it matters
Security deposit cap	Missouri allows two months' rent; several states cap at one or one and a half; some set no limit. Over the cap and the excess is recoverable, sometimes with penalties.
Deposit return deadline	Ranges from 14 to 60 days, often with a mandatory itemised statement. Miss it and you can forfeit the right to withhold anything.
Late fees and grace periods	Some states cap the fee, some mandate a grace period, many do neither and apply a reasonableness test.
Entry notice	Commonly 24 hours, but not universal, and some states specify permitted hours.
Required disclosures	Lead paint is federal. Beyond that, states differ on meth contamination, mold, bed bugs, flood history and more.
Pet fees and deposits	Some states fold pet deposits into the overall cap; assistance animals are not pets and cannot be charged for.

Cities add rules on top, and this is the layer out-of-state investors miss. Columbia, Missouri operates a Rental Unit Conservation Law: a unit must pass inspection and hold a current Certificate of Compliance before it can be let, and the certificate is attached to the lease as an exhibit. Nothing in a generic template would ever tell you that.

If you're buying out of state, the single most expensive assumption you can make is that the lease that works at home will work there.

Where This Leaves You

A good lease is unremarkable for its entire life and then suddenly the most important document you own. Write down the things that feel too obvious to write down — who mows, what appliances came with it, what happens in month thirteen — because those are the ones you'll be arguing about.

If you want the drafting handled, PacRent generates a complete lease for your state and city, carries the right clauses and exhibits across on renewal, and tracks the deposit and the key dates through the tenancy. You can see how that fits together in how PacRent works, and if you're still setting up how money arrives, start with the best way to collect rent from tenants.

And to repeat the point this started with: get an attorney in the property's state to read whatever you end up using. A drafted lease — however thorough, and whoever or whatever produced it — is a starting point for that review, not a replacement for it.
