Seller wants to close in nine days and my best buyer needs twelve

The move most people miss is that the extension ask and the assignment are not sequentially locked, you can get the assignment signed first and frame the three-day extension to the seller as a title company scheduling issue rather than a buyer problem. Title companies genuinely do need extra runway sometimes, and sellers who hear "my buyer needs more time" read that as cold feet, while sellers who hear "the title company has a backlog" read it as administrative. Same three days, different conversation.

The risk nobody has touched here is what happens to your assignment fee if the buyer uses the timeline friction as a reprice lever. At 119k with a 9k fee baked in, a buyer running a credit line at even modest carrying costs has a real number to point to when they say the deal changed. If they come back and say they will do it at 116k because of the uncertainty, you are now deciding whether to eat 3k of the fee, go back to the seller for a 3k price reduction, or let the deal die, and you are making that call with nine days already on the board. The cleaner protection is a non-refundable earnest deposit from the buyer at assignment signing, large enough that walking costs them something real, because a buyer who has put up 2k or 3k in non-refundable money does not reprice over a scheduling hiccup. What does your current assignment agreement say about buyer default and whether you keep the deposit if they reprice and you reject it?

The assumption doing the most work here is that the seller's nine-day deadline is fixed. In a motivated seller situation, that date usually comes from somewhere, a move date, a probate calendar, a servicer's timeline, and if you know the source you know how hard the wall actually is. Before you negotiate timing, find out what is driving the nine days.

On sequencing: getting the assignment signed before you go back to the seller gives you one thing, proof of a real buyer, but it costs you flexibility, because now the buyer knows you need the extension and has a reason to reprice. Going back to the seller first keeps the buyer's position cleaner but signals that your deal is not wrapped. Neither sequence is clean. The question is which party has more ability to move, and that usually comes down to the seller's actual situation, not the contract date.

The repricing risk you named is real. A cash buyer running a credit line or a rate-locked bridge product treats a three-day slip as a line-item cost. Some will absorb it, some will shave it from the assignment fee, and some will use it as an exit. If your buyer is the type who reprices on timeline slippage, you want to know that before you go back to the seller, because a 12 to 15-day extension request that causes the buyer to drop the purchase price $2,000 to $3,000 has just eaten a third of your fee.

On the default question: this is where a licensed attorney needs to look at the specific language, not a forum. What I can say mechanically is that modification request clauses and earnest money forfeiture triggers vary significantly by contract and by state, and in a nine-day window you do not have time to find out you read that clause wrong.

What is the source of the seller's nine-day number, and have you asked directly whether it has any flexibility?

The person who posted this knows the mechanics well, so I want to make sure a newer reader following along can actually use this thread too.

A few terms first. The "close date" is the calendar day the property legally changes hands. "Earnest money" is a deposit the wholesaler puts down when signing the contract with the seller, typically a few hundred to a few thousand dollars, and it signals good faith. A "default clause" is the contract language that spells out what happens if either side fails to perform, sometimes the seller keeps the earnest money, sometimes either party can walk with no penalty, depending on how the contract was written.

On the actual question: the order matters, and the contract language is what decides which order is safer. If your contract with the seller has a modification or extension clause, you can request more time without it reading as a default. If it does not, asking for an extension can look like you are unable to perform, which hands the seller a reason to back out and potentially keep your deposit.

One thing you may not have considered: some wholesalers build a short extension option directly into the original seller contract, something like a five-day right to extend for an additional $100 added to the earnest money. That clause costs almost nothing to negotiate in at signing and removes the awkward conversation entirely when a buyer's timeline does not match.

On the buyer repricing: that is real, and it is worth calling your buyer before you approach the seller, not to ask permission, but to confirm whether twelve days is a hard limit or a preference. Sometimes it is soft.

What does your current seller contract say about modification, and who drafted it?
