The transactional funder's fee is flat whether the loan lives two hours or two days, but most term sheets treat a failed B-to-C closing as a separate problem.
What I want to understand is how funders actually price the failure scenario relative to the success scenario, because the risk profile is completely different. In the success case, the funder collects the flat fee, the deed chains record in order, and the loan is repaid the same session. In the failure case, the funder holds a demand note, possibly no recorded security instrument, and a middleman who may not have the cash to repay without the C buyer's wire. The flat fee was priced on a two-hour loan, not an indefinite workout. Some term sheets I've seen address this with a default rate that kicks in after closing day, but the rate is almost never high enough to compensate for the collection exposure if the wholesaler is now illiquid.
The more interesting question is what the term sheet says about the funder's recourse when the A-to-B deed recorded but the B-to-C leg collapsed. The funder has a grantee in the chain, the wholesaler owns the property, and the end buyer walked. The funder's demand note is now an unsecured claim against someone who holds a property they can't flip. That is a different asset than what the fee priced. A funder who understood that risk at the outset would either require a recorded deed of trust on the A-to-B leg as a condition of funding, or price the flat fee to include a failure reserve, and almost none of them do either.
When your term sheet failed to close on the B-to-C side, did the funder's default language treat the wholesaler as a borrower in default, or did the instructions describe it as an escrow failure with the funder as a party to the escrow rather than a lender?
