Hi,
Can someone tell me the cost of living in Port-of-Spain? I would like to rent a 2 bedroom house near Mt.Hope hospital.Also what would be the monthly instalment for a used car in TT?
Would a salary of 28000TT pm ( before taxation) be sufficient for a family of two?
What are the overhead expenses like medical insurance, electricity bills,internet ,landline connection etc?
I hope somebody would give me some suggestions.
Thanks in advance.
