Real estate investing is a contract business. Every interaction between landlord and tenant, owner and manager, applicant and property is governed by written agreements. Get these contracts right and you protect your investment, your tenants, and your time. Get them wrong and you expose yourself to lawsuits, lost rent, and regulatory penalties.
Here are the essential contracts every landlord and property manager needs — what each one must include, where the legal risks hide, and how to create them properly.
1. Residential lease agreement
The lease is the foundation of every landlord-tenant relationship. It is the single most important document in real estate management because it defines every right and obligation for both parties.
What it must include
Core terms:
- Full legal names of all tenants (every adult occupant should be on the lease)
- Property address and description (unit number, parking space, storage unit)
- Lease term — start date, end date, renewal terms
- Rent amount, due date, accepted payment methods
- Late fees and grace period
- Security deposit amount and conditions for return
Required clauses:
- Maintenance responsibilities — who handles what. Typically the landlord covers structural repairs, plumbing, electrical, and HVAC, while tenants handle minor maintenance like changing light bulbs and air filters
- Entry and access — most states require 24–48 hours written notice before landlord entry, except in emergencies
- Termination and renewal — notice period requirements (30, 60, or 90 days depending on jurisdiction), automatic renewal terms, early termination penalties
- Subletting policy — whether tenants can sublet, under what conditions, and whether landlord approval is required
- Pet policy — allowed species, weight limits, pet deposits, monthly pet rent
- Governing law — which state's laws apply, venue for disputes
Common mistakes
The most expensive lease mistakes are omissions, not errors. Landlords consistently fail to include:
- Lead paint disclosure — federally required for properties built before 1978. Missing this disclosure can result in penalties up to $19,507 per violation
- Mold disclosure — required in California, Indiana, Maryland, New Jersey, and other states
- Bed bug policy — increasingly required in states like New York and Maine
- Rent increase terms — rent-controlled jurisdictions limit annual increases; your lease cannot override local caps
A well-drafted lease handles all of these before they become disputes. Create a lease agreement → with jurisdiction-specific clauses built in.
2. Property management agreement
If you own more than a few units — or you own rental property in a different city — you likely need a property manager. The property management agreement defines exactly what that manager can and cannot do with your property and your money.
What it must include
Scope of authority:
- Rent collection and deposit handling
- Tenant screening and lease execution — can the manager sign leases on your behalf?
- Maintenance and repair authority — what is the spending threshold before the manager needs owner approval? ($200? $500? $1,000?)
- Eviction authority — can the manager initiate evictions, or must the owner approve?
Compensation:
- Management fee structure — typically 8–12% of collected rent for residential, 4–8% for commercial
- Leasing fee — typically 50–100% of one month's rent for placing a new tenant
- Maintenance markup — some managers charge 10–20% above contractor costs
- Early termination fee — what happens if you fire the manager mid-contract
Reporting and accountability:
- Monthly financial statements (income, expenses, net operating income)
- Annual property inspection reports
- Tenant communication logs
- Maintenance records and receipts
Key risk: authority creep
The most common dispute in property management is authority creep — managers making decisions they are not authorized to make. Without clear spending limits and decision boundaries, a manager might approve a $15,000 roof repair, sign a below-market lease to fill a vacancy quickly, or waive late fees without owner approval.
Define every boundary in writing. If it is not in the agreement, the manager will eventually make the decision for you.
3. Rental application
The rental application is both a screening tool and a legal document. It collects the information you need to evaluate prospective tenants while complying with fair housing laws.
What it must include
Applicant information:
- Full legal name, date of birth, Social Security number (for credit checks)
- Current and previous addresses (last 3–5 years)
- Employment history and income verification
- References — current landlord, previous landlord, personal references
Required disclosures:
- Application fee amount and whether it is refundable (California caps application fees and requires receipts)
- Screening criteria — what will cause a denial (credit score threshold, income-to-rent ratio, criminal history policy)
- Fair housing notice — you cannot discriminate based on race, color, religion, sex, national origin, familial status, or disability (federal) plus additional protected classes in many states
Authorization:
- Consent to run credit and background checks
- Consent to contact current and previous landlords
- Consent to verify employment and income
Fair housing compliance
The rental application is where fair housing violations most commonly begin. Apply the same screening criteria to every applicant. Document your criteria before you start screening, not after. If your threshold is a 650 credit score and 3x rent income, apply it uniformly.
Criminal history screening is evolving rapidly. Several jurisdictions have "ban the box" laws that prohibit asking about criminal history on the initial application. Others require individualized assessments rather than blanket policies. Check your local requirements before designing your application.
4. Move-in/move-out checklist
This is the document most landlords skip and most landlords regret skipping. The move-in/move-out checklist documents the condition of the property at the start and end of a tenancy. Without it, security deposit disputes are nearly impossible to win.
What it must include
Room-by-room documentation:
- Walls — paint condition, holes, marks, stains
- Floors — scratches, stains, carpet wear, tile damage
- Windows — cracks, screen condition, lock functionality
- Fixtures — light switches, outlets, faucets, cabinet hardware
- Appliances — operational condition, existing damage, cleanliness
- Exterior — landscaping condition, driveway, patio, fencing
Best practices:
- Complete the checklist with the tenant present at move-in
- Both parties sign and date the document
- Include photographs with timestamps
- Complete the same checklist at move-out with the tenant present (or with documented notice)
- Compare move-in and move-out checklists to determine legitimate deductions
Why it matters legally
In most states, landlords bear the burden of proving that damage occurred during the tenancy. Without a move-in checklist, the tenant can claim any damage was pre-existing. With a signed checklist and photos, the landlord has contemporaneous evidence that the property was in a specific condition at move-in.
Some states — including Arizona, Georgia, and Washington — explicitly require landlords to provide a move-in condition statement. Failing to provide one can result in forfeiting the right to retain any portion of the security deposit.
Beyond the basics: additional documents
Depending on your property and jurisdiction, you may also need:
- Pet addendum — species, breed, weight, vaccination requirements, pet deposit, additional rent
- Parking agreement — assigned spaces, guest parking, towing policy, additional fees
- Lead paint disclosure — federally required for pre-1978 properties (EPA Form)
- Mold disclosure — required in several states, recommended everywhere
- HOA rules acknowledgment — when the rental property is in a homeowners association
- Lease renewal or extension — modified terms for a new lease period
Each of these should be a signed addendum attached to the primary lease agreement, not informal verbal arrangements.
