What documents do foreigners need to buy a house in Turkey

I’ve been seriously looking into buying a small house in Turkey, but I’m getting lost in all the legal requirements. Some sources say foreigners only need a passport, while others mention tax numbers, translated copies, and something called a TAPU. It’s confusing because every website seems to list different steps and required papers. Before I even start looking at specific homes, I want to make sure I understand what documents are actually necessary. Has anyone here completed the purchase process and can share a clear list of what’s needed from start to finish?
