01 / THE SITUATION
A house can be perfect while the owner is still waiting for their next home to be ready. If the parties assume they can “work it out later,” the buyer may end up paying mortgage installments while still renting elsewhere.
✳ THE IDEA TO REMEMBERClosing and physical possession are not always the same event.
02 / A BETTER WAY TO HANDLE IT
The practical approach
Before arras, confirm whether the home will be delivered vacant at the notary or subject to a separate agreed occupancy period. Have counsel draft explicit possession, utilities, insurance, condition and delay provisions, including how keys and an inventory will be handed over.
03 / THE EXPENSIVE TRAP
What to watch for
Never assume an informal statement that the seller’s new house will be ready “by spring” is enforceable. Delay arrangements can have significant legal and financial consequences.
04 / YOUR NEXT MOVE
Do this before you move on
Calculate the cost of every extra month of overlapping rent and mortgage, then decide how much certainty you need in the agreement.
✳ FIELD NOTEIf an offer, contract or rule sounds too simple, save the original document and check the current written conditions.
✳ MORE DETAIL / STEP BY STEP
Go deeper: details worth checking
Give yourself a paper trail before the situation becomes urgent. For a Spanish administration, a landlord, a car dealer or a school, the most persuasive file usually contains a dated request, the correct identity information, and a short explanation of the action you need. If somebody says the rules have changed, ask which office, document or contract clause they are relying on. Keep the official reference and your evidence together so that the next person can understand the case without starting from zero.
An extra practical step
Put possession date, keys, condition of handover, utilities, costs during continued occupation and any agreed security arrangements in the deed or a lawyer-reviewed annex.
A costly pitfall to avoid
Ownership at the notary and physical possession are different questions. A vague “we'll leave soon” can create expensive uncertainty.
Three questions to settle first
Which document proves this?
Who is responsible for the next action?
What is the deadline or response route?
Write down the answers, the name of the person or office who confirmed them, and the date. Save PDFs or screenshots where the conditions could change. That small habit makes it much easier to challenge an error, compare alternatives, or continue the process weeks later.
