Citizenship/Residency by Investment to Grenada vs Turkey vs Portugal

Hey

Has anyone here researched the CBI route to Turvey vs Grenada?

There are increasing reports saying countries are now heavily scrutinizing the CBI at Grenada. Also, how is the real estate market at Grenada? Research suggests it's a tepid 1.5%-4% pa.

Turkey, being a part of islamic spheres, is also coming under some pressure for issuing inaccurate CBI passports.

What would this crack down mean for current applicants?

I personally still prefer Grenada because of the global access and minimum to none stay requirements for passport.

All suggestions are welcome.
