Good to know

Holiday rental needs a tourist licence in the Comunitat Valenciana. Check that this property has one, or can get one, before you count on this income.
In some years the rental income does not cover the mortgage and costs. Keep a cash reserve for those years.
VAT of 10% on stays of 30 nights or less is in a decree that still needs approval by the Spanish Congress. You can switch it off under Rental income.
