- 5:00 PM is literal. The due diligence period expires at 5:00 PM on the stated date, not at midnight, and not at the end of business.
- The length is negotiated, not standard. There is no default due diligence period in North Carolina — the number in the contract is whatever the parties agreed.
- The deadline does not move for a weekend or holiday. Unlike some deadlines elsewhere, it lands where it lands.
- The fee is not refundable once the period has begun, whether or not you terminate.
- Extensions require a written, signed agreement. A verbal extension is not an extension.

How long is the due diligence period in North Carolina?
There is no standard length. It is negotiated on every contract, and the number in yours is whatever the parties agreed. Anyone quoting a default is describing a local habit, not a rule. What sets the length in practice is how much work the buyer needs to complete — inspections, appraisal, loan conditions, well and septic where they apply — weighed against how much uncertainty the seller will accept.
What does 5:00 PM actually mean here?
It means 5:00 PM. A termination notice delivered at 5:01 PM on the expiry date is late, and the right to terminate for any reason is gone. The deadline also does not shift because it falls on a weekend or a holiday — unlike some deadlines elsewhere, it lands where the arithmetic puts it. That is the single most expensive detail on this page.
What happens if the period expires?
The unrestricted right to walk away ends. The earnest money, which was refundable during due diligence, is now at risk if the buyer fails to close without a contractual basis. The due diligence fee was never refundable — it went to the seller when the contract became effective and stays there regardless of outcome. The due diligence fee explains how that differs from earnest money.
Can the period be extended?
Only in writing, signed by both parties. A text message agreeing in principle, a verbal yes from the listing agent, or an email that was never countersigned are not extensions. Sellers commonly ask for an additional fee in exchange, and they are entitled to refuse entirely. Ask early — a request made two days out is weaker than one made a week out.
Is the settlement date the same as closing?
No. Settlement is when the parties have signed and funds are in the attorney's hands. Closing happens when the deed and deed of trust are recorded, which is usually the same day but can be the next. You do not own the house, and you should not move in, until recording. North Carolina requires a licensed attorney for the legal work — what the closing attorney does sets out the rest.
Check these dates against your contract
This calculator works forward from an effective date you supply. The effective date itself is a defined term and is not always the day you signed — it is when the last party's acceptance was communicated. If that date is wrong, every date below it is wrong. Confirm it with your agent and your closing attorney before relying on anything here. Informational only, not legal advice.
