A practical guide to real estate due diligence — how PE, corporate buyers, and M&A teams size commercial property risk, lease economics, zoning, and physical condition before specialists run full CRE packages.
Real estate due diligence is the property and occupancy workstream inside a broader deal. It is not only a title search. For PE and strategic buyers, CRE diligence answers: Do we own what we think we own? Will the cash flows (or cost basis) survive close? Can we use, finance, insure, and operate the asset as underwritten?
Scope expands when the target is real-estate heavy (retail, industrial, multi-family, hospitality, healthcare, logistics) or when the operating company owns or long-leases material facilities. Light office leases still matter: change-of-control clauses, remaining term, and landlord consent can block integration plans.
| Pillar | What you prove | Typical owners |
|---|---|---|
| 1. Title & ownership | Chain of title, exceptions, easements, liens, access rights | RE counsel + title company |
| 2. Survey & boundaries | ALTA/NSPS survey, encroachments, legal description match | Surveyor + counsel |
| 3. Leases & occupancy | Rent roll fidelity, options, defaults, estoppels, SNDAs | RE counsel + asset team |
| 4. Zoning & entitlements | Permitted use, nonconformity, permits, parking, expansion | Land-use counsel / planner |
| 5. Physical & capex | Structure, MEP, roof, life safety, deferred maintenance | PCA engineer |
| 6. Economics & risk overlays | NOI quality, taxes, insurance, env/flood, ground leases | Underwriting + specialists |
| Stage | Typical work | Access needed | Decision use |
|---|---|---|---|
| Pre-LOI screen | Public ownership, tax assessor, tenancy signals, zoning district, flood maps, news/litigation | Public only | Kill or price property risk early |
| Post-LOI / PSA | Title commitment, survey order, lease abstract, PCA, insurance review | Access agreement / data room | Confirm underwriting; plan cures |
| Estoppel / SNDA window | Tenant estoppels, landlord estoppels on ground leases, lender forms | Tenant / landlord outreach | Freeze lease economics |
| Pre-close / 100 days | Cure list, escrow, COIs, transfer taxes, integration of facilities | Ownership transition | Fund path + ops continuity |
Traditional CRE packages (counsel, title, survey, PCA) often start in the mid-five figures for a single commercial asset and scale with portfolios and ground leases. A structured public-information pack at $49 (or $39.20 with DI20-WELCOME) helps deal teams triage property-heavy targets before funding full specialty scopes.
| Severity | Signal | Why it matters |
|---|---|---|
| Deal-killer | Uncurable title defect or missing access / easement | Cannot convey clean title or operate site |
| Deal-killer | Anchor tenant with free termination / default + no credit path | NOI collapses; financing fails |
| Deal-killer | Zoning nonconformity that blocks current use or required parking | Illegal use risk; forced relocation |
| High | Material ground lease with short remaining term or hostile landlord | Hold-period risk; refinance friction |
| High | Deferred roof/MEP/life-safety with large unfunded capex | Day-one cash drain |
| High | Flood / seismic / insurance non-renewal signals | Underwriting and hold-period failure |
| Watch | Rent roll vs financials small variances | Ops discipline; usually reconcilable |
| Watch | Expired certificates of occupancy with open applications | Administrative risk; track cures |
| Approach | Typical cost | Timeline | Best use |
|---|---|---|---|
| Public first-pass pack | $49 / target | Minutes to same day | Screen many names before LOI |
| Title + survey package | ~$2K–$15K+ (market-dependent) | 1–4 weeks | Single commercial asset |
| PCA / engineering | $3K–$25K+ | 1–3 weeks | Physical condition & capex |
| Full CRE counsel + specialists | $15K–$75K+ per complex asset | 30–60+ day diligence window | Portfolio, ground lease, multi-use |
Use as a buyer workplan. Tag items Deal-Killer / High / Watch as evidence arrives. Groups below mirror how deal teams staff the CRE workstream.
Before LOI, buyers often need a fast view of whether a target is light-lease ops or a property-heavy story with concentration risk, ground leases, or multi-site industrial footprints. A structured first-pass using public ownership records, tax assessor data, news/litigation, sector rent trends, and known site patterns helps allocate scarce title, survey, and PCA budget.
After LOI, CRE counsel, title companies, surveyors, and engineers own formal opinions. Your IC memo should still connect property findings to valuation, leverage, insurance, and integration — not park them in an appendix nobody prices.
Order a structured public-information diligence pack for your target — useful for pre-LOI triage alongside specialist title, survey, and PCA work, not a replacement for legal opinions or appraisals.
