> For your leveraged investments, pay yourself in refinanced cash when your investments appreciate and/or credit rates drop.

In other words: Gamble that (1) your investments appreciate, or (2) that you will find credit rates drop when convenient.

In 1 word: Gamble.

So, either you are rich and have spare money to gamble, which sure, might be beneficial against taxes. But you could also gamble against any other sector (stocks, housing, startups...)

Or, if you are not rich, just put it in the 401k (or eq).
