Because if you buy a house, it’s just you and the bank, so you need to cover the banks risk for you as an individual, meaning higher interest rates. Larger purchases, or a group of houses are covered by different loan types, flexible rates at for example international rated plus half a point… and that is mich cheaper. The rate might fluctuate… but if the government strongarms the fed to keep the loans practically free, companies borrow for free plus half a point. And that is a lot of difference.
