A double close where a 35k spread underwrote to 9,800, and every dollar of the gap is traceable

Even careful underwriting can miss the mechanics of a structure it hasn't run before. Take a double close: A-B at 224k, B-C at 259k, same day, cash on both ends, 35k in the spread column building the plan for the month. Here's where a spread like that tends to erode. Two sets of closing costs, because a double close is two real purchases and each has its own settlement fees, title work and recording, often totaling somewhere near 9,600 combined when only one set was budgeted out of habit. Funding at 3 points plus a flat fee can run 8,000 or more if the funder is engaged eleven days out instead of a month out and the first quote is taken without shopping it. A comparable file can price closer to 2 points with more lead time. Deed transfer tax gets charged on each conveyance in many states, meaning it's paid going in and collected again going out, easily 4,000 or more total on a deal this size. A rush fee to get a payoff cut same day, plus miscellaneous costs that don't get itemized carefully enough to explain later, can add another 1,500 to 2,000. 35,000 minus roughly 24,000 in real costs leaves closer to 11,000, and a small credit to the end buyer for a repair item can bring it down further still. None of this is hidden information, closing cost duplication on a double close is well documented. The mistake is carrying an assignment mindset into a structure that has two of everything, and not building a line-item sheet for the second closing until the numbers are already fixed. The fix: build the funding quote and both settlement estimates before the seller contract is signed, not after, and get at least two funding quotes in writing. If the spread doesn't survive that sheet, it isn't a double close worth doing.
