I hope to get there one day.
There's no secret that you did all that grinding to get to where you are at, maybe, prior to 40. That grind is essential to who you are, and hopefully, who you continue to be. Would you want your partner to have that similar trait?
The rich people use real estate to depreciate their earnings and bring down their taxable income. Example, Let's say you earn 250k a year. Your fed tax bracket is 24% (approx). 250k 24% = 60,000.00. The standard deduction is 12,950, so you are down to $47050. You purchase a 2million dollar investment property and you get to depreciate the building, land is not depreciate. 2m divided by 27.5 years (depreciation) is approx. $72,727k a year. There you go. You now pay no taxes aside from FICA. The additional $25,677k "loss" is carried over to subsequent years. This is how the rich minimize or eliminate most taxes.
Others, who have massive securities (bonds/stocks/preferreds/UITs/etc) can actually "borrow" from their holdings via margin; assuming the interest rate is low enough, and their gains/dividends pay the margin off and they have legal tax free money. This is what Mark Zuckerberg, Elon Musk, Larry Page and others do. One doesn't need a few billion to do this. You can do this with a couple of million; but it may be a fruitless endeavor.
Example. One has $2,000,000 in securities. Their margin rate is 2%, in theory, they can "borrow" on margin $1,600,000 at 2% margin. Their annual maintenance on the 1.6m; assuming a person "borrowed" all of it would be $32,000 a year in margin interest. However, if they have dividends and bonds paying 4%, they are earning $64,000 a year in interest. So, they can legally "write-off" the $32,000 in interest, while borrowing $1,600,000 and still earning in dividends an additional $32,000 a year. Their personal tax liability would be only on the $32,000, not the $64,000 in earned dividends nor the $1,600,000 they used on margin. If the dividends are mutual bonds in their state, the dividends would be federal and state free.
Not accounting advice, just hypothetically how it works.
