What money though?I think the whole point is that’s not true. If you’d have kept those mortgages, assuming you refi around 2.5-3%, and put that extra money in investments, you’d have more money.
In the end it might not matter, and it sounds like you’re happy with your financial situation, but to say “you can really start using your salary to my money” isn’t accurate because you gave up a lot of money over the past X years.
You’re talking about a second mortgage? The money is tied up in the value of the house. They aren’t giving you a check for that money to invest is what I’m saying. Unless you take out a large second mortgage or have substantial funds to put towards the investment portfolios, this “plan” doesn’t work at all.
