There is no standard amount, because the due diligence fee is negotiated and the standard North Carolina contract does not require one at all. What it should be depends entirely on how much competition a specific listing has, and in New Hanover County this fall, where the typical home takes 61 days to go under contract and two of every five active listings have already cut their price, most buyers are not in a position where a big fee buys them anything.
We will say the uncomfortable part first. Nobody publishes an average due diligence fee for the Cape Fear region. Not Cape Fear REALTORS, not the North Carolina Real Estate Commission, not the MLS. So when an agent tells you the going rate here is some round number, they are telling you about their own last few deals. That is not nothing, but it is not data, and it is a bad reason to hand a stranger money you cannot get back.
What you can do is understand exactly what the fee is, what it buys, and what the market is asking of buyers right now. Then size it on purpose.
What the fee actually is, and what it is not
Under the standard North Carolina Offer to Purchase and Contract, form 2-T, the due diligence fee is defined as a negotiated amount, if any, that the buyer pays the seller for the right to terminate during the due diligence period. Four things follow from that definition, and each one surprises somebody.
It goes to the seller, not into escrow. Paragraph 1(d) requires it to be delivered to the seller by the effective date, which means you write that check at contract acceptance rather than at closing. It becomes the seller’s property on the effective date. It is credited back to you at closing if you buy the house. And it is not your earnest money, which is a separate deposit that does sit in escrow and does come back to you if you terminate during due diligence.
It is also optional. The Real Estate Commission has been explicit that neither state law nor the Commission requires you to use the trade association form or to include a due diligence fee at all. A zero-dollar fee is a legal offer. Whether it is a competitive offer is a different question, and the answer changes listing by listing.
When you get it back, which is almost never
This is the piece buyers most often misunderstand, and it is worth being blunt about. Under paragraph 1(i) of form 2-T, the fee is nonrefundable with narrow exceptions: a material breach by the seller, a termination by the buyer under paragraph 8 or paragraph 12, or an addendum that says otherwise. The Real Estate Commission’s own guidance notes that actual refunds are rare, and NC REALTORS materials add that recovering the fee after a seller’s material breach can be slow and expensive if the seller does not simply hand it back.
So treat the fee the way you would treat a non-refundable deposit on a wedding venue. You are buying an option. If you walk, for any reason or no reason, inside the due diligence window, you keep the right to walk and the seller keeps the fee. That is the whole bargain.
How we actually size it
We look at three things, in this order, and none of them is a percentage of the purchase price.
First, what competition does this specific listing have? Not the county. The listing. A house that went live Thursday in a tight price band in Ogden or Porters Neck with three showings booked is a different negotiation from a house that has sat 90 days with a price cut behind it. The county numbers below tell you which situation is more common right now, but your agent should be able to tell you which one you are in before you write.
- New Hanover County: 61 days on market, up from 34 a year earlier, with 1,251 active listings and two of every five carrying a price cut Our New Hanover County market update, three months ending September 2026
- Brunswick County: 93 days on market against 64 a year earlier, with about 38 percent of active listings already cut Our Brunswick County market update, three months ending September 2026
- Pender County: 83 days on market against 51 a year earlier, and the only county of the three where listings with a price cut fell, down about 19 percent Our Pender County market update, three months ending September 2026

Second, what does walking away actually cost you? Add up what you will spend inside the due diligence window: the inspection, any specialty inspections, a survey if you are getting one, the appraisal if you order it early, and the insurance quotes. If you terminate, you lose all of that plus the fee. A buyer who intends to spend $1,400 on diligence and writes a fee larger than that has more than doubled the cost of changing their mind, which is exactly what the seller wants and exactly what you should decide on purpose rather than by habit.
Third, how does the fee trade against the length of the period? These two are linked. A seller giving you 30 days instead of 14 is taking more risk, and will reasonably expect more fee. If you can run your inspections quickly, a shorter window with a smaller fee is often a better offer for you and reads as stronger to the seller. We cover the seller’s side of that trade in our post on how long to give a buyer for due diligence in NC.
What the fee cannot buy you
A due diligence fee does not extend your rights. It does not give you a longer period unless the contract says so, it does not obligate the seller to make repairs, and it does not protect you if you miss the deadline. On that last one, the deadline is absolute. At 5:00 p.m. on the stated date your right to terminate for any reason ends, and after that your earnest money is at risk too. We wrote about what happens next in our post on whether a buyer can back out after due diligence in NC.
It also does not substitute for doing the work. A large fee with a rushed inspection is the worst version of this contract, and we see it. Plan the actual diligence first and the fee second. Our checklist is in what you should actually do during due diligence, and the current inspector pricing is in what a home inspection costs in Wilmington.
Everything above argues for restraint, and restraint can cost you a house. The county averages do not apply to every price band. Well-priced inventory under $400,000 in New Hanover County still moves quickly, and on those listings a thin due diligence fee is the first thing a seller uses to separate your offer from the one behind it. There are also sellers who read a small fee as a buyer who is not serious, fairly or not. So this is not a case for writing zero. It is a case for knowing which situation you are in, deciding the number deliberately, and being able to explain it to the listing agent. We would also rather you spend the money on a better inspection than on a bigger fee, and we will say so even when a larger fee would make our job easier.
Related questions people also ask
Is the due diligence fee the same as earnest money?
No, and confusing the two is expensive. The due diligence fee goes directly to the seller at contract acceptance and is generally not refundable, while earnest money is held in escrow by a third party and is returned to you if you terminate within the due diligence period. Both are credited toward your purchase at closing if the sale goes through. If you terminate before the deadline you normally lose the fee and keep the earnest money.
Do I have to pay a due diligence fee in North Carolina?
No. The North Carolina Real Estate Commission has stated that neither state law nor the Commission requires the parties to use the trade association contract form or to include a due diligence fee, and the form itself defines the fee as a negotiated amount, if any. An offer with no due diligence fee is a valid offer. Whether a seller accepts it depends on what other offers are in front of them that day.
Can I get my due diligence fee back if the inspection finds something terrible?
Generally no, and that is the hardest sentence in this whole subject. The fee is what you paid for the right to walk away, so discovering a reason to walk is the fee doing its job rather than grounds for a refund. The narrow exceptions in the standard contract involve a material breach by the seller or termination under specific paragraphs, and the Real Estate Commission’s guidance notes that actual refunds are rare. Ask a North Carolina real estate attorney about your particular facts before you assume you have a claim.
Before you write your next offer, ask your agent two questions in writing: how many showings has this listing had in the last seven days, and what has the seller already done on price. Then set your due diligence fee against that answer and against what your inspections will cost you, not against a number somebody quoted as standard. If you want help reading a specific listing’s position before you commit money you cannot get back, that is the work our Buyer Advantage Program exists to do, and our team will walk through the offer with you line by line.
