Decide who handles which part of the move
Family or paid helpers may pack, transport, or meet visitors. Make those roles clear without assuming they can decide sale terms. Keep the owner's approval separate from day-to-day help with the property.
Use the next address to guide the belongings plan
Identify what will fit, what needs storage, and what requires another decision. This is more useful than a general promise that the house will be empty soon. Explain unresolved items before agreeing to the buyer's possession expectations.
Keep an up-to-date transition list
Moving arrangements can change quickly. Track what has been completed and what remains before the house could be handed over. If a possible purchase progresses, review the written terms against the current list rather than the original moving plan.
Raise distance and timing constraints together
If the smaller home is elsewhere, discuss who could deal with the property after you leave. Confirm any signing or travel requirements before finalizing arrangements that depend on the sale.
