Transactional funding on a 12,000 spread is almost never worth it, but the cutoff is not where most people put it
Take a property under contract at 95k and a confirmed end buyer at 107k. The spread is 12k. Transactional funding on a two-day hold typically runs 1 to 2 percent of the acquisition price plus a flat fee, so call it 1,100 to 2,000 depending on the funder and the state. Two closing cost sets on a cash-to-cash transaction add another 1,800 to 3,200 combined, depending on title rates in that county. At the wide end of both figures you are net 6,800 on a 12k spread, which is a 43 percent haircut before you have paid for any of your own time or errors. An assignment on the same deal costs one closing and no funding fee, so net closer to 10,500 if the seller and end buyer will both sign the paperwork showing what they are each paying. The double close wins exactly when the seller or the end buyer refuses to proceed knowing the other side's number, and the spread is wide enough that two closing costs plus funding still leave a number you would show up for. The real threshold in my experience reading these files is closer to 20k spread before the double close math becomes comfortable rather than survivable. Below that, the question is whether the privacy is worth the cost, and that is a preference, not a calculation. The clause that matters is in the transactional funding agreement, specifically whether the funder's fee resets if the end buyer's closing slips a day, because a 1-day extension on some term sheets triggers a second flat fee that turns a thin deal into a loss. What is the spread you are actually looking at, and do you have a funding quote in hand yet?
