Real Estate Due Diligence Checklist: Never Miss a Red Flag

Why Due Diligence Matters

Due diligence is the investigation process between getting a property under contract and closing. It's your opportunity to verify everything the seller told you, uncover hidden problems, and confirm that the deal is what you think it is.

Skipping due diligence — or rushing through it — is how investors lose money. A $300 title search can save you from a $50,000 lien surprise. A $400 inspection can reveal a $25,000 foundation problem before you're stuck with it.

The Complete Checklist

Title and Ownership

• Order a full title search from a title company
• Verify the seller is the actual owner
• Check for all liens: mortgage, tax, mechanic's, judgment, HOA, IRS
• Identify any encumbrances: easements, deed restrictions, covenants
• Review the chain of title for gaps or irregularities
• Confirm no pending litigation involving the property
• Verify no pending code violations or demolition orders
• Check for any recorded agreements that affect the property

Physical Inspection

• Schedule a professional home inspection ($300-500)
• Inspect roof: age, condition, remaining life expectancy
• Inspect foundation: cracks, settling, water intrusion
• Inspect electrical: panel brand and age, wiring type, capacity
• Inspect plumbing: pipe material, water pressure, drainage
• Inspect HVAC: age, condition, functionality, capacity
• Check for water damage: stains, mold, musty odors
• Check for pest damage: termites, carpenter ants, rodents
• Assess structural integrity: walls, floors, ceilings, load-bearing elements
• Evaluate all windows and doors: operation, seals, condition
• Test all fixtures and appliances
• Note any safety hazards: missing railings, exposed wiring, trip hazards

Environmental

• Check FEMA flood zone designation (floodmap.gov)
• Assess for asbestos risk (homes built before 1980)
• Assess for lead paint risk (homes built before 1978)
• Check for underground storage tanks (especially former commercial properties)
• Review environmental databases for contamination history
• Check radon levels (especially in basements)

Financial Verification (Rental Properties)

• Request 12-24 months of rent rolls
• Request 12-24 months of operating statements (P&L)
• Verify actual rents collected vs. lease amounts
• Review all current leases for terms, expiration dates, and special provisions
• Verify security deposits on hand
• Review utility costs (request 12 months of utility bills)
• Verify property tax amount with the county assessor
• Get insurance quotes from 2-3 carriers
• Verify HOA fees and any pending special assessments

Market and Location

• Pull comparable sales within 0.5 miles and 6 months
• Drive the neighborhood at different times (day, evening, weekend)
• Check crime statistics for the immediate area
• Research school ratings (affects property values and tenant quality)
• Verify zoning designation and permitted uses
• Check for planned developments nearby that could affect value
• Review days on market for similar properties
• Assess rental demand: vacancy rates, rental listing speed

Legal and Regulatory

• Verify property survey matches the legal description
• Check for any open building permits
• Confirm certificate of occupancy is current
• Review local landlord licensing requirements
• Check rent control or stabilization regulations
• Verify short-term rental regulations (if planning Airbnb/STR)
• Confirm property use is consistent with zoning

Contractor and Repair Verification

• Get 2-3 contractor bids based on your renovation scope
• Verify contractor is licensed, insured, and bonded
• Check contractor references (call previous clients)
• Get detailed written scope of work with timeline
• Confirm permit requirements for planned renovations
• Estimate total rehab cost with 15% contingency

Timeline

Most contracts allow 7-14 days for due diligence (the inspection contingency period). Prioritize:

• Day 1-2: Order title search, schedule inspection
• Day 3-5: Inspection completed, title preliminary report received
• Day 5-7: Contractor bids received, financial documents reviewed
• Day 7-10: All due diligence complete, make go/no-go decision
• Day 10-14: Request repairs, renegotiate, or waive contingency

Red Flags That Kill Deals

1. Foundation issues costing $15K+ unless the discount covers it
2. Environmental contamination with unknown remediation costs
3. Title defects that can't be resolved before closing
4. Liens exceeding the purchase price with no short sale approval
5. Zoning violations that prevent your intended use
6. Fraudulent financials on rental properties (inflated rents, hidden expenses)
7. Structural damage from fire, water, or termites that's more extensive than visible
8. Neighborhood decline that doesn't support your ARV or rental assumptions

The Bottom Line

Due diligence is your safety net. Every dollar you spend on inspections, title searches, and verification can save you thousands in surprises after closing. Use this checklist for every deal — no exceptions. Order the title search on Day 1. Schedule the inspection on Day 1. Get contractor bids by Day 7. Make your go/no-go decision with complete information. The deal that looks great on paper must survive due diligence to become a great deal in reality.
