I came here at 43 and it was the best thing I did. You're still young and energetic enough to enjoy it, and have the maturity to appreciate the unique circumstances you find yourself in. Nothing better than being freed from the shackles of being an employee. To the Op, invest your 600k into two high yielding buy to lets in London and then come here. The fact you already have an elite visa, means you’re already a step ahead from some of the other 40-ish entrepreneurs who moved here.
