The quickest way would likely be to borrow it from somewhere else. Do you have any shares in an investment portfolio by any chance?

If you transfer those to Interactive Brokers, it's quite easy (and relatively cheap -- 3.7% a year) to borrow money against them (margin debt). Unless markets crash tomorrow that should allow you to bridge things.

The stock market has been falling hard lately. If ever there was a time NOT to take such a risk, now is probably it.

Depends on how much you borrow, and how large your portfolio is.

Unfortunately that isn't an option for me either
