Property Records You Must Keep (and for How Long)

Part of the Property Documentation pillar guide. This article handles retention; the pillar covers the broader record system retention applies to.

A former tenant emails you in March 2027 about a 2024 deposit deduction. They claim they never got an itemized statement. You shrug, that was three years ago, you’ve turned over the unit twice since, and the file is gone.

Two months later, you’re answering a small-claims summons. The judge wants to see the itemization. You don’t have it.

This is how most landlords learn about retention periods: in hindsight, holding a notice they can’t respond to.

Why retention matters more than it sounds like it should

Records retention isn’t filing cabinet hygiene. It’s the difference between defending yourself and writing a check.

The records you throw away too early are the ones you needed. The records you keep forever in a chaotic Dropbox folder are the ones you can’t find when it counts. Both failures look the same in court: you can’t produce the document, so the other side’s version wins.

Four scenarios will come for your records, sooner or later:

• Tax audits. The IRS can generally go back three years, six years if there’s a substantial understatement, and indefinitely for fraud. State tax authorities have their own windows.
• Tenant disputes. Statutes of limitations on written contracts vary by state but commonly run 4-6 years after the breach. Some states allow longer.
• Fair Housing complaints. HUD and state agencies can investigate complaints filed within a year (sometimes longer for litigation).
• Eviction defense. A tenant fighting an eviction may demand records going back the entire tenancy.

None of these will give you a polite heads-up. The records have to already exist when the demand arrives.

What “keep” actually means

Before we get to specific categories, define what retention means for you.

A photo on a phone you replaced last year is not retained. A PDF in an email account you stopped using is not retained. A lease in a banker’s box in a storage unit you visit twice a year is technically retained but not usable.

Retained means three things:

1. Findable. You can produce it within an hour of someone asking for it.
2. Readable. It opens, displays correctly, and isn’t a screenshot of a screenshot.
3. Verifiable. The document carries enough metadata (date, signatures, file integrity) that the other side can’t easily argue it was made up after the fact.

A box of crumpled receipts technically meets retention. A searchable PDF archive with timestamps actually does.

Lease agreements and addendums

Keep at least: 7 years past the end of tenancy. Many attorneys recommend 10.

Lease agreements are the foundational document of every relationship you have with a tenant. The lease is what makes a deduction enforceable, a violation prosecutable, and an eviction legitimate.

Retention should outlive the tenancy by years. The tenant who moved out in 2023 can sue you in 2027 in many states. They can also call you as a witness or counterclaim against you in an unrelated case. You want the lease.

What to keep, specifically:

• The signed lease itself, with all initials and signatures legible
• Every addendum, pet, smoking, parking, lead-based paint, mold, anything signed separately
• Move-in inspection reports and signed acknowledgments
• Renewal documents, even if they’re just “extended by email”
• Notices of rent increases and tenant acknowledgments

If you’re using paper, scan everything. If you’re using email-only signing, save the full signed PDF, not just the email confirmation. A clean move-in record with photos and signature belongs in the same folder as the lease, not in a separate phone roll.

Security deposit documentation

Keep at least: the statute of limitations in your state, plus 2 years for safety. Often 4-8 years.

The deposit file is the one tenants come back for. They forget how much they paid. They forget what they signed. They remember being charged $400 for cleaning and they want to argue about it.

Your file needs to defensibly answer four questions:

1. How much did the tenant pay, and when? Receipts, bank deposit slips, or PMS records.
2. Where was it held? Many states require deposits in a separate or interest-bearing account.
3. What was deducted, and why? Itemized statement with photo evidence and receipts.
4. When and how was the balance returned? Check copy, certified mail receipt, or signed acknowledgment.

If a deduction is contested, you need the deduction letter, the move-in photos, the move-out photos, and the receipts for repairs, all linked, all dated. Walking into court with a folder where the photos are on one device and the receipts are in your email and the letter is on a thumb drive is a way to lose a winnable case.

Maintenance records and receipts

Keep at least: 7 years for tax purposes. Longer for warranty and habitability defense.

Maintenance records pull double duty. They’re tax documentation (repairs are deductible, improvements are capitalized), and they’re habitability documentation (proof you fixed things when tenants reported them).

For each repair or maintenance event, you want:

• The request. When the tenant first reported it. Email, text, or work order, preserve the timestamp.
• The response. When you acknowledged it and what you said.
• The work. Vendor invoice, scope of work, parts list.
• The completion. Date the work was finished, ideally photos of the result.
• The payment. Receipt or paid invoice with method of payment.

Receipts for repairs under a certain dollar amount may seem disposable. They aren’t, especially when a tenant later claims the unit was uninhabitable for six months. Your defense is the paper trail showing you responded promptly each time something broke. If you’re not already tracking this consistently, the maintenance documentation guide is a reasonable starting point.

For tax purposes, the IRS generally recommends keeping records that support an income or deduction on a return until the period of limitations runs out, which is typically three years from filing, but six years if you underreport income by more than 25%, and indefinitely if you don’t file or file a fraudulent return. Most accountants say seven years to be safe. Consult yours.

Tenant communications

Keep at least: the duration of the tenancy plus 3-5 years.

The texts, emails, and notes from a tenancy are often the deciding evidence in a dispute. The tenant who says “I told you about the leak in October” loses if your email archive shows the first mention was January. They win if you have nothing.

Most landlords lose communication trails three ways:

• Switching phones without preserving texts
• Using a personal email account that gets cluttered or deleted
• Verbal-only conversations with no follow-up email

Fix one thing at a time. Start by confirming verbal conversations in writing: a short email after a phone call summarizing what was said. Keep texts in a single dedicated number if possible. Archive emails by tenant or property in folders you actually use.

For lease violations specifically, the conversation log is everything. A first noise complaint that goes nowhere is fine. A first noise complaint that you can’t produce, when you’re trying to evict on the basis of the fifth one, is a problem. Document each one when it happens, the lease violation record approach builds this trail without much extra work.

Tax records

Keep at least: 7 years. Some categories longer.

Tax records for rental properties are their own category. The IRS generally has three years to audit a return, but the window extends to six years under certain circumstances and is unlimited in cases of fraud or unfiled returns. Most accountants recommend seven years as a default.

Specific tax-relevant items:

• Annual income and expense statements
• 1099s issued to contractors
• Property tax bills and payments
• Depreciation schedules, keep these for the life of the property plus seven years after sale
• Mortgage interest statements
• Closing documents from property purchase, keep until you sell, then keep for at least seven more years
• Capital improvement records, same as closing docs, since they adjust your cost basis

The depreciation schedule is the one people lose. It tracks years of basis adjustments. Lose it and you may struggle to calculate gain or loss accurately when you sell.

Consult your accountant for what applies to your specific situation. Tax retention is general guidance that varies by entity type, state, and circumstance.

Insurance and claims records

Keep at least: the policy period plus 7 years. Longer for any claim.

Insurance policies, especially for properties, can become relevant years after they expire. A water-damage claim from a 2022 incident may surface in 2026 if there’s downstream damage. The original policy documents, claim correspondence, and adjuster reports should outlive the immediate event.

For any claim, keep:

• The original claim filing and date
• All correspondence with the insurer
• Photos and damage documentation
• Adjuster reports and estimates
• Final settlement documents and payments
• Receipts for any covered repairs

Move-in and move-out documentation

Keep at least: 7 years past the end of tenancy.

This category overlaps with leases and deposits, but it deserves its own paragraph because the photos are usually where retention fails.

Move-in photos on a phone you’ve since replaced are gone. Move-out photos saved “to your camera roll” are buried under three years of family pictures. Photos taken by an employee who no longer works for you may have left with them.

A defensible move-in/move-out record needs photos that are dated at capture, organized by unit and by event (move-in vs. move-out), and stored somewhere durable. The point of linking move-in and move-out photos is so they can be produced side-by-side at the moment of dispute, not pieced together from three devices weeks later.

A working retention schedule

If you want a single-page version of all of the above:

These are starting points. Your state’s statute of limitations on contract claims, deposit-return requirements, and habitability standards may extend any of these. An attorney in your jurisdiction is the right person to set hard floors.

The retention problem solves itself when records are born digital

Most retention failures aren’t decisions. They’re accidents. The photo got deleted because you needed phone storage. The receipt got tossed because the receipt pile got too big. The lease got lost in an office move.

The records that survive are the ones that were generated in a durable format from the start, a signed PDF instead of a paper signature, a timestamped photo set instead of a phone roll, an emailed receipt instead of a paper one. Born-digital records don’t need a filing system to survive seven years; they need a folder and a backup.

DiscoveryMark generates each move-in, move-out, maintenance, and violation record as a single PDF with photos, timestamps, and signatures baked in. Retention becomes a matter of where you save it, not whether the pieces still exist when you need them.
