Selling and buying together

In short: Most movers sell and buy at the same time, aiming to exchange contracts on both on the same day and complete on the same day. Getting your sale agreed before offering makes you a stronger buyer. Use one solicitor for both if possible, keep your mortgage offer and porting on track, and agree a realistic completion date across the chain. If timings don't line up, options include renting in between, delayed completion or short-term bridging finance.
