2 cents worth - I'd guess there's more chance of instructing than charter flying coming along....when things return to "normal".... with your travels you should have a better feeling regards the charter market.
Spending more $$ on this and that without a job offer, just can't see the point IMHO.
Instructing may not be your preferred option Vs charter work but if willing to travel may provide a start before a charter position comes along.
Good luck.
