I just came across the Velocity Banking concept a few days ago. For context, I have a high net worth, high W2 income, and a diversified investment portfolio in real estate, e-commerce, and another sector of industry.
My home is worth $650k and I owe $300,000 on it. If I take an 80% LTV 1st lien HELOC, that's a loan of $520k, which will be reduced by $300k to pay off my first mortgage.
So now I have a "mortgage" of $300k. Then I switch my lifestyle in that all my monthly expenses (around $5k) go against the HELOC. All my W2 and business revenue go against the HELOC as well....I'm estimating it to be somewhere in the $18,000 - $22,0000 a month. Less expenses, that's a net of $13k-$18k principle reduction each month. And that doesn't take into account by using the available $300k in equity to buy more investments which produce more income which goes to more principal pay down.
So again, I'm trying to see the downside here. What am I missing?
