I have been living in Japan with my husband for the past 3 years. We are both British. I work for an IT consulting firm with only a handful of staff where I am the only foreigner. I'll be turning 30 next year and I would like to start a family. Since it's my first child, I'd really like to be at home in the UK, close to my Mum and MIL. I've spoken to my Boss and he's willing to let me work remotely from the UK indefinitely.
I'd like to get a mortgage in the U.K with my husband. How do mortgage lenders validate overseas income and credibility? Can I work remotely from the U.K without paying taxes (N.I, etc?) if I'm already getting taxed here? If not, how does a Japanese company go about this? I'd like to qualify for a mortgage and I'm not sure what the best procedure course of action is due to my salary which essentially will become foreign income.
