    As a dual citizenship single person, with no income this year, selling house for roughly half million, and wishing to expat. I understand I would not owe capital gains when I have no income this year, correct? Should I sell and deposit money in US banks, then move to foreign country and renounce US citizenship? Or buy foreign house first, then renounce? I don’t understand mark to market tax implications. Or should I renounce before buying foreign house? Will I be able to move money out of US banks after renouncing, having no travel possibility back to US? Should I open foreign account before renouncing, and move money there? Or should I buy foreign house, then do US income taxes next year, declare all foreign accounts, then renounce? Thanks for your input.
