Can I get citizenship in Spain if I buy a house?

Could you please clarify for me, is it possible to acquire Spanish citizenship simply by purchasing a property in the country? I've heard rumors that investing in real estate might lead to citizenship, but I'm not entirely sure how accurate these claims are. Do you know if there are specific criteria or requirements, apart from buying a house, that need to be met in order to become a Spanish citizen? Would this process involve a lengthy application and approval period? And, importantly, does the type or value of the property purchased play a role in the citizenship determination? I'd appreciate any insights you could provide on this matter.
