Stop high interest mortgage loans forever by capping rates at 2% and sell the bond created from the mortgages to the homeowner, not some foreign investor looking for a higher investment rate.
Why is this important?
Housing is all about the monthly payment, no matter if you call it rent, a lease, or mortgage. The higher the interest rate the higher the monthly payment. Investors jack up that rate. If the bonds from those rates were sold to homeowners, the pressure would be to lower interest rates. Homeowners would fund their fellow homeowners and get a modest retirement income at the same time.
