6k monthly, wether you are single or coming with a partner should suffice and let you have a nice living standard, even if you have to rent an apt/house. You should do your homework regarding health insurance though as I believe most companies don´t get new affiliates past a certain age. A family´s friend is retired and earns 6k usd monthly and he travels a couple of times a year, eats out twice a day, has a live in maid etc.
