The right order depends on your equity, financing, timing, risk tolerance, and available temporary housing. Selling first provides greater certainty about your proceeds, but it may require a flexible closing date, temporary move, or post-closing occupancy agreement. Buying first gives you more control over where you move, but it can create additional financial and timing pressure.
I compare both scenarios, including estimated proceeds, carrying costs, market conditions, and contingency options, to develop a coordinated plan for moving up, downsizing, or relocating.
