Where Does the Money Come From for Mortgage Loans?
Mortgage Backed Securities
Once Freddie Mac, Ginnie Mae, and Fannie purchase the pools, they break them down into smaller ownership parcels. These are called "mortgage backed securities." Each security represents a small ownership interest, not in your specific loan, but in the pool of which your loan is only one part. The risk is therefore diversified and it is a very safe investment.
The mortgage backed securities are sold on Wall Street to institutions or individuals looking for a safe investment, but one that earns a higher interest rate than treasury bonds. You may even own some as part of your retirement fund or investment portfolio. Perhaps you have heard of Ginnie Mae bonds? Those are securities backed by the mortgages on FHA and VA loans.
By selling the bonds, Ginnie Mae, Freddie Mac, and Fannie Mae obtain new funds to buy new pools so lenders can get more money to lend to new borrowers.
