You need to factor in medical insurance cover, travel expenses.

This plan won't work as the UK immigration authorities don't distinguish between local and remote working. All work of any kind is forbidden on a tourist visa. However, perhaps you are too pessimistic about getting a work visa. It doesn't depend on income level but on supply and demand. If you have a skill that is in short supply you are in with a chance of finding a UK company to sponsor you. Check out the list below - it varies from year to year. https://www.gov.uk/government/publicati … april-2013

with £50,000 pretty confortable, the only thing is how you're planning to make that amount as at the moment the tax rate is 40% of your income if you earn more than £33,000 a year, you might be able to get some benefits for the kits but that's all really, London's rents are quite expensive, although the other cost of living are quite cheap

well id technically be living there but on a tourist visa.  As i said my work is based in the states but i can work virtually.  So i wouldnt actually be paying British taxes.

Yes, but you can't live there on a tourist visa. The limit is 6 months in any 12-month period. You may get away with it once but if you try to do more you will be denied entry to the UK and sent back home on the next flight.
