I don't agree. Anyone with equity can use it to leverage into more equity over time. Someone living in a rented apartment with no significant savings and no significant assets certainly can't do it. Someone part-way through a mortgage on a house/condo, who hasn't absolutely maxed out what the bank would give them to buy it in the first place (it's insane what they'll give you, we never went beyond 1/3 of what the bank said we qualified for), has the ability. The interest rate isn't important either, really, as long as it's lower than you can get with other investments.Those days are gone Rob. It worked for you and that’s great.
Not at all the same thing. I made a targeted attack on *one* asset, the airplane. Rolled it into my mortgage the first chance I got. From then on, I had only one debt, the house, and we were far enough into the mortgage that if everything went sideways we'd be able to sell the house and have enough to live off for a while or for a down-payment on something smaller. As it turns out, my wife and I both had unemployed sections during the mortgage. I was laid off twice. It still worked out.This was a common strategy at the time. I had a neighbor do the same, not with airplanes, but other stuff. He had a great job, leveraged his house for cars, boats, pool, etc…. lived large.
Lost his job, had no liquidity in any assets, and lost everything.
tl;DR - There are good and bad ways to leverage assets, it comes down to having a plan (including an exit plan) and planning for contingencies.
