Is it better to have an Independent insurance advisor ?
Do they also have an agenda to promote certain products?
The advantage of IFA over tied is that IFA are supposedly more fair towards products from all insurer since they do not have have extra incentive to sell products from specific insurer. However, this is assuming the IFA is a brand neutral person, to not have any personal inclination towards any brand. IMO, a brand neutral person is someone who is indifferent between sharp and toshiba TV, or Dell and Lenovo laptop. The products are chosen based on specs.
IFA are coloured by the same bias a tied agent has in choosing product type. Selling ILP/unit trust is more profitable to ETF for both IFA and tied agents.
hence, the person whose agenda is aligned to your own financial health is yourself. You might perhaps also consider financially savvy friends who are not agents. Note that people who major in finance for their degree do not count as financially savvy. Financially savvy is not only knowing the financial computation, but also actively applying it to present instruments to evaluate their relative value.
Insurance agents offer their 'experience' and time spent learning personal finance in exchange for hundreds of thousand of your future money.
Your hourly wage is likely to be below the savings you can achieve by learning about personal finance, and hence the time spent on learning personal should be financially justified.
As for the inexperience, it can be covered by consulting in open forums, and hopefully, there are people to highlight any potential pitfall in your tentative plan.
