This strategy makes it more difficult to launder large amounts of money, and that's their goal. Hypothetically, let's say that the overhead to launder a billion dollars is 20%. If this increases it to 25%, then they've effectively taken 50 million dollars out of illegal circulation. That's a heck of a lot more effective than drug busts.
For clarification, I have no idea what the overhead on money laundering is, but I can't imagine it's cheap to move vast sums of money around off the books.
If one does not need a mortgage, this is actually the recommended way to transact on a high-value property. It makes estate planning easier, it somewhat protects privacy, and when it's time to sell, one simply sells the underlying LLC, which ironically is a much simpler business transaction in most states than selling a piece of real estate.
(I seem to recall Zuckerberg doing this for his Palo Alto home with a variable interest rate loan that started with 2% or so)
It's a mortgage in layman's terms as there's some principal and interest, but in reality the financial institution won't send an appraiser, there's no mortgage deed issued to the bank, the balance and interest payments are not sliced and diced into securities to be resold.
With that said, mortgages for LLCs are the preferred financing instruments for real estate investors, so they're actually a significant line of business for some banks and yes, they're very doable.
Or is it that the loan is such a low interest rate that it makes more financial sense to keep making money with his cash through investments, say at ~10% return, to offset the loan interest?
On a macro level, the government penalizes selling of assets at 23.8% (current long-term capital gains + ACA surcharge) and on the other hand encourages borrowing by keeping the rates low and allowing the interest portion to be deducted as an investment expense, so what's a rational person to do?
It’s possible that folks trying to launder money will switch from doing a single $20M transaction to doing 20 $1M transactions instead, and not change their level of overall activity. At the very least it’ll be a pain in the ass for them, though.
This might not be the ideal policy, but it’s easily explainable if you try to look at it from government officials’ perspective. (So I wouldn’t really call it “odd”.)
And the titles companies on whom executing this regulation will fall... It's not like they all have the resources to hunt down shell companies all over the map.
