You could fly to London on Monday morning and work until Thursday afternoon (4 x 10 hours/day or 4 x 8 hours/day). You would sleep in a hotel for 3 nights/week in London and most probably pay less than for a monthly rent. Then you could build your home almost everywhere (the only limitations are good flight connections to London). Maybe you could even negotiate partly remote work. During work you would sleep 4 nights at home and 3 nights in London. During holidays you would be at home all the time. If you manage, you can even retire early. Since homes one hour flight from London can be much cheaper you would be able to pay for them faster...
