Real Estate Due Diligence Checklist: Essential Steps, Red Flags & Who to Involve Before Closing
The goal is simple: confirm that the property matches representations, identify liabilities, and quantify repair or compliance costs before closing.
What to check first
– Title and ownership: Obtain a title search to confirm legal ownership, identify liens, easements, covenants, or unresolved judgments that could affect use or transferability.
– Zoning and land use: Verify zoning classification, allowable uses, setback requirements, and any pending zoning changes or variances. For redevelopment projects, confirm density, height limits, and parking requirements.
– Surveys and boundaries: Commission a boundary or ALTA/NSPS survey to identify encroachments, boundary discrepancies, and accurate parcel dimensions—critical for development and financing.
– Building condition: Schedule a comprehensive building inspection plus specialized inspections (roof, HVAC, plumbing, electrical, pest, and structural) to estimate immediate and deferred maintenance costs.
– Environmental assessments: For commercial or land-sensitive sites, order Phase I environmental site assessment; follow up with Phase II testing if there are red flags like underground storage tanks, industrial use history, or soil staining.
– Financials and leases: Review rent rolls, operating statements, service contracts, security deposits, and existing leases. Confirm tenant payment history, lease expirations, and any common area maintenance reconciliations.
– Permits and code compliance: Check building permits, certificates of occupancy, and any outstanding code violations. Unpermitted work can lead to costly remediation or denial of occupancy.
– Insurance and risk exposure: Review current insurance policies, claims history, and replacement cost estimates.
Confirm insurability for hazards such as flood, earthquake, or wildfire in high-risk areas.
– Utilities and infrastructure: Confirm utility service availability and capacity, sewer and stormwater connections, and any shared access or maintenance agreements.
– Tax and assessment status: Verify property tax bills, special assessments, and any tax abatements or incentives that affect cash flow or future liabilities.
Common red flags
– Clouded title or unresolved liens
– Major undocumented structural defects
– Environmental contamination or history of industrial use
– Significant unpaid taxes or assessments
– Large lease rollovers or tenant concentration risk
– Unpermitted additions or ongoing code violations
Efficiency tips that preserve leverage
– Start due diligence early and align contingency deadlines with your financing approval timeline.
– Use a checklist template to ensure nothing is missed and to standardize review across multiple properties.
– Order time-sensitive reports like surveys, environmental assessments, and building inspections immediately after entering contract.
– Negotiate access for contractors and engineers upfront to avoid scheduling delays.
– Keep communication transparent with sellers—many issues can be resolved through credit adjustments, escrow reserves, or agreed remediation plans.
Who to involve
A robust due diligence team typically includes a real estate attorney, licensed surveyor, certified inspector, environmental consultant, structural engineer, and an accountant familiar with real estate financials.
For commercial assets, a broker or property manager adds useful market and operational insight.
Thorough due diligence turns uncertainty into actionable knowledge. By following a structured checklist, prioritizing high-risk items, and involving the right specialists, buyers and investors can protect capital, uncover upside, and close with confidence.
