I follow you but I think this is one of your worst stories.

Home purchases are at a historically high level even with the high prices and a pandemic.

A down payment is not always required to purchase a home. You don't have to get your mortgage from a bank. I have purchased three homes the last one was just 18 months ago.

Not everyone is young and poor. Home mortgage interest is not quite as evil as you make it sound.

The current 30 year fixed rate is less than what a lot of people think is the current rate of inflation and the interest is tax deductible.

I don't currently have a mortgage but was considering getting one and investing the money with rates so low and the interest being tax deductible.

Banks and mortgage brokers rarely hold on to mortgages they are usually quickly sold. Banks and brokers mostly make money from originating the mortgage not from collecting interest.

No bank making mortgages creates new money. They have to borrow it from someplace, either investors or other banks who have to borrow it from somewhere maybe even from the Fed. Their borrowing is limited by reserve requirements.

You said most people don't understand mortgages and you are right and that includes you.

Just a reminder, only the Federal Reserve, the U.S. treasury and counterfeiters can create new dollars. Everyone else is just playing with the money already in existence. Even the U.S. deficit is funded with dollars already in existence.
