Can you explain why this is? Is it because I am somehow at a greater risk if the market really drops? If I can pay the line off at any time doesn't this give me more flexibility? I would be really eager to understand the reasons why this is a bad strategy. What is the general downside of the strategy and what is the worst-case down side?
TBH he would probably need to know a lot more about your overall financial picture to begin to accurately assess what you should do. This is obviously info that your financial advisor is privy to that none of us ITT are.
In general though what he is saying is that taking out a 2M+ loan is risky when you aren't remotely guaranteed to be able to use your assets to throw off the income to do that. The more conservative approach would be to wipe the 2M out with your 6.4 and have 4.4 and no debt.
Worst-case downside tough to predict but if your assets greatly deplete while in the market, it is gonna make paying the loan tougher and may effect other parts of your life/finances. Again though, like I said we just have a slice and your advisor does have more info.
Advisors sometimes make decisions for individuals as if they have no emotion and are soulless profit seeking corporations looking for the best EV possible, but with a 2.5 million dollar loan outstanding and no income to speak of since you just cashed out then it might be tougher to sleep at night. Especially if things start to go south with the market, think Chop was mainly saying if it were him he would lockup the peace of mind.
