Firstly welcome to the forum, don't be put off by anything said on the forum, you really need to come to the IOM and see what its actually like for yourself, it's only then you'll know if it'll ever be the right or wrong choice for you.
Personally I can no longer afford to live on the IOM, I've effectively been priced out of the market, but if you've got a well paid job, some savings and enough to buy a house over here then you'll probably find the IOM cheaper to live than many parts of the UK. Steam packets fares (commonly known here as steam racket) are expensive but only if you take a car, a foot passenger return is cheap and many airlines are offering flights to main UK airports for around £50-£100 return
