The Rental Property Due Diligence Checklist

Due diligence is the period between an accepted offer and closing when you confirm that the property is what you think it is. A checklist keeps you organized and reduces the chance of missing something costly.

Red flags to take seriously

• Seller resists inspections or document requests.
• Numbers that change between conversations.
• Unpermitted additions or conversions.
• Title issues that cannot be explained.
• Residents who report problems the seller did not disclose.

Financial review

• Rent roll and leases for every unit.
• Twelve months of income and expense records.
• Bank deposit records to confirm rent collections.
• Utility bills for owner-paid services.
• Property tax bills and assessment history.
• Insurance quotes for your coverage.
• Service contracts.

Resident review

• Lease terms, expiration dates, and renewal options.
• Security deposit amounts.
• Payment history and current balances.
• Any pending disputes or eviction filings.
• For voucher units, HAP contracts and inspection history.

Physical inspection

• General inspection by an inspector you choose.
• Specialist checks as needed: sewer scope, roof, structural, electrical, HVAC, environmental.
• Code compliance and permit history.
• Photos and notes for every unit.

Legal review

• Title commitment and exceptions.
• Survey, if appropriate.
• Zoning and permitted use, including the number of legal units.
• Rental registration or certificate requirements.
• HOA documents, if applicable.
• Any open code violations.

Market check

• Comparable rents and sales.
• Vacancy trends in the area.
• Planned developments or changes nearby.
• Housing authority payment standards, if you plan to accept vouchers.

Other risks

• Flood zone and environmental concerns.
• Insurance availability and cost.
• Property tax changes after sale.
• Local ordinance changes.

Finishing well

Summarize findings, decide what affects price or terms, and negotiate before contingencies expire. If the property no longer meets your criteria, be willing to walk away.
