Your own Lawyer: in Spain, the Notary Public only executes the deed, so all preparatory work needs to be done by the buyer’s (and seller’s) lawyers. They draw up the private sale agreement and perform all the due diligence concerning the property, (building) permits, or debts encumbering the property (related to a mortgage or arrears).Your lawyer will charge +/- 1,21% of the purchase price for this service.
