Selling Spanish real estate looks to be tricky:

So you have a combination of factors:
Locals don’t have the income to buy a €1.4 million house.
Foreign investment is being told the market will be upside-down next year. :(
You might want to talk to a financial advisor in your country to figure out the best way out.
I guess, worst case, you hold and convert it to a rental property. Wait for the market to re-build, then sell it.
Given how climate change is impacting everything, other seasons are likely more appealing than Summer.

“A new heat record for June of 46C was set on Saturday in the town of El Granado, according to Spain’s national weather service, which also said this month is on track to be the hottest June on record.”
46° (115° F) in JUNE! I don’t even want to contemplate August.
