It is important to note that most of the online experiences you will come across are net-negative. Forums and other venues give the ability for those that are dissatisfied a way to vent. It should be obvious, but you should not be following any influencers when looking for tax advice, citizenship by investment programs, or any other form of life planning.
On the topic of Turkey, I've found local law firms, banks, and real estate professionals to be just that, consummate professionals. Furthermore, registering in the government address registration system (e-Devlet)︀ does absolutely not make you a tax resident. Judging by that comment, the OP appears︁ to have received very poor advice and has no real boots on the ground in︂ Turkey. Also, Turkish banks are not known to have issues with bank cards outside of︃ Turkey; it would be nice to know which bank and location this was an issue.︄ Turkish bank Garanti BBVA for example is one of the best known ways to acquire︅ Amex charge cards (Platinum, Centurion). There is a less cumbersome process than dealing with Amex︆ directly and annual membership fees are cheaper, while retaining most of the important benefits. The︇ bigger question is why are you dealing with local Turkish banks? There are many better︈ jurisdictions in to bank, invest in, and be a tax resident in. Acquiring citizenship does︉ not force one into any of the aforementioned things.
As for real estate, real estate︊ is a "bad investment" in most cases for most people. This is of course not︋ black and white and is highly dependent on your net worth and investment strategy, and︌ obviously your need for citizenship in the country you're investing in, but usually the overheads︍ of maintenance, property taxes, interest on loans, and cost of opportunity with having large amounts︎ (relative to most peoples portfolios) locked up in real estate while they can be earning️ more with similar risk elsewhere are all factors. Trophy real estate is often times desired by the wealthy as a store of value because unlike most asset classes real estate is not as volatile and has a low maximum draw down. Unless you're operating a for profit real estate business with a large number of rental units in highly stable economies and earning in very stable currencies real estate is in most cases a bad investment if you're looking for stable cash flows. Even so given that most of the world's developed countries are running perpetual deficits or are endlessly printing there are real estate︀ bubbles all over in US, China, Turkey, and Russia to name a few.
