Due Diligence
The investigation and verification process buyers conduct before committing to a real estate purchase.
Definition
Due diligence is the process of investigating and verifying all material facts about a property and transaction before closing. It's the period during which you confirm that the property is what the seller represented it to be — and that your underwriting assumptions are valid.
Key components of investor due diligence: property inspection (structural, mechanical, roof, plumbing, electrical), title search (confirming clear title and no hidden liens), review of financial documents (rent rolls, leases, expense statements for income-producing properties), environmental assessments (Phase 1 for commercial), zoning verification, and permit history.
Due diligence periods are contractually defined — typically 10–30 days for residential, 30–60 days for commercial. If you discover material issues during due diligence, you can negotiate a price reduction, request repairs, or walk away and reclaim your earnest money (depending on contract terms).
Skipping or rushing due diligence is one of the biggest mistakes investors make, especially in competitive markets. Never let FOMO pressure you into waiving due diligence on a property you haven't properly inspected.
