It depends almost entirely on what the seller is looking for and how realistic that search is. Price point, bedroom and bathroom count, and neighborhood all factor in, along with whether the seller has actually been out seeing suitable properties or is starting from zero. A good buyer's agent asks the listing side directly what the seller is searching for. If the criteria are unrealistic for their budget or area, the deal may never close, and you want to know that before you tie up your own timeline. More often than not, though, sellers who accept a contingent offer have already been looking and have seen homes they like, sometimes one already picked out. In that case the contingency generally adds little time. The real requirement is a seller who is genuinely willing to work through the contingency and has a reasonable plan for their own move. Get a professional on both sides who knows how to structure this, with clear timelines and a defined exit if the seller can't perform, and the deal stays manageable rather than open-ended.
