I am a non-EU citizen. I have no criminal records and have clearance report from my country. I want to know how difficult or easy it is if I just open a bank account in Spain and deposit 100k in the account. I already have worldwide medical insurance which covers me all over Europe. Do I need to keep showing proof of property rental despite keeping 100k deposited in Spain? Also, if I keep the money deposited in the Bank then how SECURE and easy is it to get renewals? Most likely within 2 years I would buy a property in Spain too but right now I need to keep my options open - I can deposit 100k in a bank account before even applying the visa as long as it makes the process faster, easier and secure!!!

Also I am already resident in France, since 1 year now - do I still need to provide police clearance certificates? Or do they have all that information sharing in a common Schengen database?
