I bought a condo nearly 5 years ago on without a retirement visa. I’m from the U.K.. I transferred my funds to my lawyer who held it in an escrow account. Very easy process. Lawyer then distributes the funds. I also didn’t have a bank account but opened one straight away as soon as I was the owner. Good luck
I’ve never had a problem leaving on time from any country but this forum seems to have a lot of people who don’t understand the concept of leaving on time
