Final answer:
Existing mortgages and servicing rights can be bought and sold in the financial market through securitization. This process played a significant role in the 2008-2009 financial crisis.
Step-by-step explanation:
True. Existing mortgages and servicing rights can be bought and sold in the financial market. This process is known as securitization, where mortgage loans are bundled together into a financial security and sold to investors. Investors receive a rate of return based on the level of payments made on the mortgages that stand behind the security. Securitization became more prevalent in the mid-2000s and played a significant role in the 2008-2009 financial crisis.
