What Is the Due Diligence Period?
The due diligence period—often called the "inspection period" or "option period" depending on state—is a window of time after contract execution during which a buyer can investigate the property thoroughly and, in most contracts, terminate without penalty if unsatisfied. This is the buyer's maximum leverage point: before the due diligence period expires, you have significant freedom to walk away; after it expires, you are committed (subject to other remaining contingencies).
Due diligence periods vary significantly by state and contract: 7–10 days is common in competitive markets; 14–21 days is more typical in slower markets or for complex properties. In some states (notably Georgia), the "due diligence period" gives the buyer an absolute right to terminate for any reason before expiration, making it essentially an option to purchase.
What to Complete During Due Diligence
Use every day of your due diligence period productively. Essential due diligence items for residential properties include: general home inspection; specialized inspections (sewer scope, radon, HVAC service, chimney, roof); review of HOA documents (CC&Rs, bylaws, meeting minutes, budget, reserve study, pending assessments); title search preliminary findings; review of seller disclosure statement; survey review; confirmation of flood zone status and flood insurance availability; zoning verification; and permit research for prior improvements.
Each inspection finding informs your negotiation or termination decision. Comprehensive due diligence before the deadline puts you in the strongest position to either negotiate repairs/credits or walk away with full knowledge of what you're getting.
Extending the Due Diligence Period
If you need more time—inspection scheduling delays, review of complex HOA documents, follow-up specialist inspections—request an extension from the seller before the deadline expires. Extensions must be agreed to in writing. Sellers often grant reasonable extension requests, particularly if you are otherwise performing under the contract. A $100–$500 option payment is sometimes requested in exchange for an extension. Never let the deadline pass while waiting for an inspector or document—send the extension request in writing even before the documentation arrives.
The Cost of a Rushed Due Diligence
Competitive markets create pressure to shorten or waive due diligence to make offers more attractive. Buyers who rush due diligence or waive it entirely are accepting unknown risk. Post-closing discovery of a major defect (failed sewer line, foundation movement, HOA financial distress) when due diligence was rushed is a costly and frustrating experience that independent investigation would have avoided or priced into the purchase.

Frequently asked questions
Can I terminate the contract for any reason during due diligence?
In states where the contract grants an absolute termination right during the due diligence period (like Georgia's standard contract), yes—you can terminate for any reason and recover your earnest money. In states where the inspection contingency requires a defect-based reason, you technically need an inspection finding to support termination. Practically, buyers in the latter states often frame cold-feet terminations around inspection results, and sellers often don't dispute the termination to avoid litigation.
What HOA documents should I review during due diligence?
Essential HOA documents include: Declaration of CC&Rs (what you can and cannot do); bylaws (how the HOA is governed); recent meeting minutes (uncover disputes, pending litigation, discussed assessments); current year operating budget; reserve study (are reserves adequately funded for future capital repairs?); insurance certificate; and any pending or recent special assessments. Reviewing these typically takes 2–5 hours but can reveal major financial or governance problems that affect property value.
Is there a difference between a "due diligence period" and an "inspection contingency"?
Yes, though they overlap. An inspection contingency ties your termination right to inspection findings—you must base your termination on what an inspector discovered. A due diligence period typically grants a broader, unconditional right to terminate (for any reason) within the period. Some contracts have both. In a contract with only an inspection contingency and no general due diligence period, your termination rights are narrower.
