Nope, I'm not comfortable with leverage, as it can be applied in both directions.
I follow the Heckler Maneuver (previously patented and implemented by the better half). Pay off the mortgage in 12 years and then start investing your payments aggressively. Granted, there is an amount of could have/should have, but no one started this thread for me in 2003, so I knew squat about FI. Luckily, my employers helped me squirrel away 10%, which also adds up!
hmmm, the Heckler Maneuver seems a lot more sound than the Smith Maneuver. you should write a book or go on forums with rabid SM acolytes and 'splain them the technique and wisdom of the HM… on the other hand nevermind. they've got themselves so twisted up in broken logic and bs that they can't see the forest for the trees and you can't convince them otherwise that's it's simply leveraged investing with the end being a lot of debt that you still pay (deductable or not) and a big question mark as to the value of your portfolio. ah well.
