What is the purpose of the secondary mortgage market (e.g., Fannie Mae and Freddie Mac)?

SECONDARY MORTGAGE MARKET: Where existing mortgages are BOUGHT and SOLD (as opposed to the PRIMARY market where lenders originate loans to borrowers). KEY PLAYERS: FANNIE MAE (FNMA), FREDDIE MAC (FHLMC), GINNIE MAE (GNMA — government-backed loans like FHA/VA); PURPOSE: They PURCHASE mortgages from primary lenders (banks, mortgage companies), which: gives lenders fresh capital (liquidity) to make more loans; spreads risk; standardizes loan requirements (conforming loans meet their guidelines); keeps mortgage money flowing and available; MORTGAGE-BACKED SECURITIES (MBS): Pools of mortgages are packaged and sold to investors; CONFORMING LOANS: Meet Fannie/Freddie guidelines (loan limits, underwriting standards); JUMBO LOANS exceed conforming limits; IMPACT: The secondary market makes more mortgage credit available and at lower rates by providing lenders liquidity; without it, lenders would run out of money to lend; this is important finance knowledge for brokers — the secondary market's role in providing liquidity and standardizing lending is a key national exam concept.
