I have watched a hundred Southern Utah sellers try to sell and buy in the same window. The breakdowns almost never happen at the kitchen-table level. They happen in the white space between desks. The buyer's lender wants tax returns on Wednesday. The listing agent did not know the appraisal got rescheduled. The title company is waiting on a payoff statement nobody asked for yet. By Friday, two clean transactions are wobbling.
I built the coordinator model to close that white space. On your sale, I am the listing agent. On your next purchase, I am the lender, and I bring in a buyer's agent I trust to represent you on the buy side. Same phone number, same person watching both calendars, both timelines, both appraisals. If your sale shifts a week, your purchase knows it the same hour.
This page walks the three real paths through a simultaneous move, the financing tools behind each one, and the honest math. No theatrical pitch. If your situation does not fit the coordinator model, I will tell you. There are moves where two separate offices is the right answer.
