Unfortunately, construction delays are very common in Spain. The handover of properties in Spain is often delayed as construction companies do not usually comply with the deadline agreed in the sale contract. These delays lead to a delayed completion that might be a reason for cancelling the contract.
If the developer or builder has missed the established deadline in the sale contract, you can cancel it. In that case, the vendor will have to refund the whole amount of money you paid so far plus interests. Otherwise, if the vendor does not do that, you can demand compensation for the damages caused by the delayed completion.
