How Does 24-Hour Exchange Work?

"Exchange" is the point at which a property sale becomes legally binding — both sides sign contracts, the buyer pays a deposit, and neither party can pull out without financial penalty. "Completion" is when the money moves and you hand over the keys. In a conventional sale, exchange and completion happen weeks apart; with a genuine cash buyer, they can happen on the same day, or within hours of each other.

Exchanging within 24 hours of an offer being accepted requires several things to already be true, which is why most conventional sales can never get close to it: a mortgage-backed buyer must have their lender's formal offer in place (typically 2–6 weeks), searches and surveys must be complete, and everyone in the chain above and below must be ready simultaneously. A single slow link — a delayed search, a buyer further down the chain still waiting on their own sale — holds up everyone.

A direct cash buyer removes most of these dependencies. There is no mortgage lender to wait on, no chain above or below, and the survey is arranged and paid for by the buyer rather than negotiated between two sets of solicitors. With title documents available and solicitors already instructed, exchange and completion can be compressed into the same day — genuinely useful when a repossession hearing, a probate deadline, or a relocation date is fixed and cannot move.

It is worth being cautious of anyone offering 24-hour exchange as a blanket promise regardless of circumstances — title complications, probate not yet granted, or unresolved leasehold issues can still add time even for a cash buyer. A reputable buyer will tell you honestly whether your specific situation can move that fast rather than promising a timeline they can't deliver.
