A due diligence fee is a non-refundable payment a homebuyer makes directly to the seller when signing the purchase contract, in exchange for the right to investigate the property and cancel the deal for any reason during a set window. The money becomes the seller’s immediately. If the sale closes, the fee is credited back to the buyer at settlement. If the buyer walks away during the investigation window, the seller keeps it. The arrangement is standard in North Carolina, where the state’s Offer to Purchase and Contract formally defines it, and similar structures exist in South Carolina and Texas (where it’s called an option period fee).1NC REALTORS®.

Due Diligence Fee vs. Earnest Money
Buyers in these states usually pay both a due diligence fee and an earnest money deposit, and mixing them up is the most common first-time buyer mistake. They do different jobs.
The due diligence fee goes straight to the seller and is the seller’s property from the effective date of the contract.1NC REALTORS®. Offer to Purchase and Contract Form 2-T (Revised 7/2025) Earnest money sits in an escrow account held by a third party, typically the closing attorney or a brokerage. The due diligence fee is non-refundable except when the seller materially breaches the contract. Earnest money is refundable if the buyer terminates during the due diligence period or under other conditions the contract allows.
The practical rule to remember: if you terminate during the due diligence period, you lose the fee but get your earnest money back. If you terminate after the period ends, you can lose both. At a successful closing, both amounts are credited toward the purchase price.
What the Fee Buys: The Due Diligence Period
The fee pays for a window of time, negotiated between buyer and seller, that starts on the contract’s effective date. Residential windows commonly run two to four weeks, though the length is entirely up to the parties. The deadline is strict. The standard form uses the phrase “TIME IS OF THE ESSENCE,” meaning that missing the cutoff by even a day ends the buyer’s right to terminate freely.1NC REALTORS®.

During the window, the buyer investigates. Home inspection. Radon and pest testing. Appraisal. Financing approval. HOA document review. Title search. Insurance quotes. Anything else that might change the decision. The point of the structure is that the buyer doesn’t have to justify a cancellation. A failed inspection, a lender problem, a lowball appraisal, or plain cold feet all work. The buyer walks, loses the fee, and gets the earnest money back.
When You Lose the Fee and When You Don’t
Every termination during the due diligence period lets the seller keep the fee. The reason doesn’t matter. A crumbling foundation, financing that collapses, a job move, or a change of heart all produce the same result. The fee compensates the seller for taking the property off the market and turning away other buyers while you investigated. As NC REALTORS puts it in its legal guidance, “the buyer has been able to exercise the right they paid for to inspect the property and terminate if they wish.”2NC REALTORS®. What Is a Due Diligence Fee and How Does It Work?
There is one meaningful exception. If the seller materially breaches the contract, by failing to deliver clear title, refusing agreed repairs, or materially misrepresenting the property’s condition, the buyer may have grounds to recover the fee.1NC REALTORS®. Offer to Purchase and Contract Form 2-T (Revised 7/2025) Recovering it in practice often requires legal action. Document everything, review the contract for refund language, and talk to a real estate attorney. Actual refunds are uncommon.
At a successful closing, the fee appears on the settlement statement as a buyer credit against the purchase price. On a $300,000 home with a $2,000 due diligence fee, the buyer brings $2,000 less to closing. The seller already has the money, so it’s an accounting adjustment.3NC Real Estate Commission. Due Diligence Fees: When Are They Refunded?
What Happens If You Back Out After the Period Ends
This is where buyers get into real financial trouble. Once the due diligence window closes, the free termination right is gone. A buyer who walks away after that point is considered in default. The seller can keep the due diligence fee and the earnest money, and may also have the right to sue for breach of contract or seek specific performance, which is a court order requiring the buyer to complete the purchase.
Most sellers in this situation don’t litigate. They keep the earnest money and relist. But the exposure is real, which is why experienced agents push buyers to finish inspections, appraisals, and financing approvals well before the deadline. If a problem surfaces late, you want time left on the clock to terminate while your only loss is the fee.
How Much and How It’s Paid
The amount is fully negotiable, and market conditions drive what counts as reasonable. In a balanced market, fees on a typical residential purchase run from a few hundred dollars up to around $2,000. In a competitive seller’s market, buyers routinely offer more to make their offers stand out, and some sources report fees reaching 1% to as much as 3% to 5% of the offer price in the most heated situations.
A larger fee signals seriousness and gives the seller more assurance, but it also raises what you lose if you walk. Calibrate the amount against your confidence in the property and your ability to absorb the loss. Sellers weighing multiple offers often look at the due diligence fee alongside the price, the earnest money, and the closing timeline. A slightly lower offer with a substantially higher due diligence fee can sometimes beat a higher headline price, because the seller sees real commitment behind it.
Payment happens when the contract is executed. Buyers typically write a check made out to the seller, and certified checks or wire transfers work as well. Once the seller has it, it’s their money to spend, not funds held aside in escrow.
Where Due Diligence Fees Apply
Due diligence fees are not a nationwide standard. They come out of North Carolina’s Form 2-T, South Carolina uses a similar structure, and Texas has the comparable option period fee. If you’re buying in a state that doesn’t use them, your right to cancel without penalty depends on the contingencies written into your purchase agreement, such as financing, appraisal, or inspection contingencies, rather than a separate up-front payment for that right.
