The largest financial risk in your life has never been diversified.

70% of household net worth. One property. One ZIP code. Harry Markowitz solved this in 1952 for equities. Home Diversification solves it for the home you live in.

THE GAP

Every other financial risk in your life is diversified. Your home is not.

  • Your Pension
Diversified across thousands of holdings.
  • Your savings
Diversified across thousands of holdings.
  • Your home
Diversified across thousands of holdings.

Markowitz showed in 1952 that this is inefficient. Home Diversification is how you fix it.across thousands of holdings.
