These MBS trade in units of several million dollars. You can’t invest $10,000.

Also, it requires a significant amount of back office support to track each individual mortgage in the portfolio and account for payments, prepayments, pay offs, etc.

They are sold in ‘packages’ of (at least) a few million $$’s at a time ….. there MAY be some specialist Funds that invest in this type of security .. however you might do better to simply buy Bank shares or property funds direct

go to any commercial bank or brokerage house…open a account///////////// tell them what you want to buy and do it………..
