The Federal National Mortgage Assn. said it had net earnings of $20.5 million during its fourth quarter of 1985. That compared to a loss of $31.2 million in the same period of 1984. The federally chartered corporation, known as Fannie Mae, credited declining interest rates for helping to offset a sharply higher number of foreclosures, especially on mortgages in economically-depressed areas. Fannie Mae is the nation's leading buyer of residential mortgages.
