The useful answer

There is no universal sequence. Compare both plans against your financing, the availability of suitable homes, your ability to carry two properties, and your tolerance for temporary accommodation.

Map four dates, not one moving day

Put the sale completion, sale possession, purchase completion, and purchase possession on one calendar. Add the actual time needed for funds, movers, access, and cleaning. A same-day transfer can look neat on paper while leaving little room for delays.

The sale-first scenario

Selling first can clarify the available proceeds, but it may require temporary accommodation or a narrower buying window. Price the fallback before choosing the sequence. Identify where you would stay, what you would store, and how long you could comfortably continue searching.

The purchase-first scenario

Buying first can secure a suitable next home, but it creates exposure if your sale takes longer or achieves a different price. Ask your lender to assess the scenario with conservative assumptions, including any bridging arrangement. Do not rely on an unapproved financing option.

The coordinated scenario

Conditions and negotiated dates may help coordinate transactions, but their availability and acceptability depend on the other parties. Understand the consequences of each condition and how one agreement affects the other. Your agent, lender, and lawyer or notary should work from the same timeline.

Write a fallback you would actually use

Define the trigger for temporary housing, a revised search, or a pricing review. Assign responsibility for each decision. A fallback is valuable only if it is affordable, available, and acceptable to the people moving with you.

Your next-step checklist

  • Align all four contractual dates.
  • Ask the lender to test both sequences.
  • Price temporary housing and storage.
  • Stress-test a lower sale price or delay.
  • Agree a realistic fallback.
