For example: I would love to know exactly how this is possible... this is an example of a benefit of insurance I found online..
You can easily make other businesses such as real estate part of the life insurance policy.
Since any funds inside life insurance policy are exempt from taxation for life, the wealthy are leveraging on this and now are combining their real estates with a life insurance policy to avoid taxes.
My only guess is to re-finance an amount of loan from your real estate then use that capital to buy life insurance. So that the interest from the re-financed amount can be used for tax deduction, plus property depreciation, maintenance expenses to be used for more tax benefits. Like others said, there are too many ways for the wealth to properly deduct tax, and yet if you do not have EA license, I'd recommend you not to make suggestions on taxation or such, just to CYA.
