Property Due Diligence Checklist: What to Inspect, Who to Hire, Common Red Flags & Negotiation Tips
What to examine — essentials
– Title and ownership: Obtain an up-to-date title report and commit to title insurance.
Check for liens, judgments, easements, restrictive covenants, and unresolved ownership disputes.
– Survey and boundaries: Secure an ALTA/NSPS or equivalent boundary survey to confirm legal property lines, encroachments, and utility easements.
– Zoning and land use: Verify current zoning, permitted uses, density limits, parking requirements, and any proposed zoning changes using municipal planning records or direct calls to the planning department.
– Environmental risks: Start with a Phase I Environmental Site Assessment to identify recognized environmental conditions.
For properties near industrial sites, wetlands, or floodplains, be ready to order a Phase II assessment and evaluate flood maps and stormwater controls.
– Building condition and inspections: Commission structural, roofing, HVAC, electrical, and plumbing inspections. Add specialized tests—pest, mold, asbestos, and lead-based paint—based on building age and use.
– Permits and code compliance: Confirm building permits, certificates of occupancy, and any outstanding code violations or open permits that could trigger remediation.
– Lease and income verification: For income properties, review all leases, rent rolls, security deposits, expense reimbursements, and tenant estoppels. Verify actual rent receipts and occupancy history.
– Financials and taxes: Audit operating statements, tax assessments, utility histories, service contracts, and pending tax appeals or assessments that could affect cash flow.
– Insurance and claims history: Request claims history and insurance policies to assess insurability and potential premium increases. Check for flood, wind, or other location-driven exposures.
Who to involve
– Real estate attorney for title, contract review, and closing conditions
– Licensed surveyor for boundary verification
– Qualified building inspectors and specialty inspectors (environmental, structural, pest)
– Property manager or leasing advisor for rent and tenant verification
– Title company for closings and title insurance
– Municipal planning or permitting contacts for local compliance questions
Digital tools that speed the process
– County recorder and assessor online databases for title and tax records
– Municipal GIS and permit portals for zoning, floodplain, and permit history
– Digital due diligence data rooms for organizing documents and communications
– Drone and thermal imaging for roof and exterior condition assessments when safe and permissible
Common red flags
– Unclear chain of title or unresolved liens
– Open code violations or missing certificates of occupancy
– Environmental issues flagged on Phase I reports or proximity to high-risk sites
– Significant deferred maintenance beyond disclosed reserves
– Lease discrepancies, unverified tenant income, or high tenant turnover
– Encroachments or easements that limit usable property area
Timing and negotiation tips
– Negotiate a due diligence period and clearly defined contingencies that allow for inspections, contract reviews, and financing approvals.
– Budget appropriate funds for inspections, surveys, and environmental studies early—finding issues late reduces options.
– Use material findings to renegotiate price, require remediation, or include escrows for repairs rather than walking away immediately.
Final steps
Compile findings into a structured report with recommendations and cost estimates.
Clearly document any closing conditions and confirm repair timelines, escrow arrangements, or seller credits before finalizing the transaction. A disciplined due diligence process turns uncertainty into confident decision-making and preserves investment value.
