Speed without preparation just produces a rushed offer, so the work happens before the search does. That means a full pre-approval on file, a lawyer already chosen for the file, and a clear number in the buyer's head for what a specific type of house on a specific type of street has actually sold for, so an offer reflects the real market rather than nerves.
Where buyers most often lose ground is condition wording. A condition of financing can be shortened without being waived, and an inspection condition can run in parallel with other steps instead of stacking on top of them, both of which shave real days off a closing timeline without leaving a buyer unprotected.
