Savings accounts . . .
interest rates are most determined by the state of
the national economy.
Mutual funds . . .
Treasury bills . . .
traded on nationwide exchanges; prices and returns
are pretty uniform nationwide.
Real estate . . .
rests directly on local conditions in each city, and sometimes even in
different parts of the same city;
affected by things like local unemployment, local bad weather,
local price of gas, local tourism, local special events, etc.
