Now, imagine that $100,000 being in your AIO.
Let’s say the interest rate is 5%.
Now it’s in an appreciating asset, as well as saving you significant interest costs on your mortgage. Say you owed $200,000 on your mortgage, and it’s an AIO. By transferring that $100,000 into your AIO, it remains as liquid as it was in that savings account, but it’s now dropped your balance to $100,000.
5% interest on a $200,000 loan will cost you $10,000 / year. That’s $27.40 per day.
5% interest on a $100,000 loan will cost you $5,000 / year. That’s $13.70 per day.
You’re now saving $416 per month—that’s a car payment--while remaining liquid the whole time. And remember: this is money that you simply moved from one account to another.
