Invest in Gibraltar
Don’t. Invest in yourself first. You have worked hard to earn your money, so be careful and don’t just hand it over to anyone in a suit.
Do your research. Come and live in Gibraltar for at least two years before you can get a handle on what is going on. You don’t want to end up with all your eggs stuck on the rock and unable to get back out.
If you have enough cash to be thinking of investing, then even if you are exploring the property market for investment, you need to be careful and be sure of what you are getting into.
There is no harm in exploring and making enquiries into the abundance of local investment companies, but do it as a paperwork exercise first.
