Ancient Chinese wisdom says a Snake in the house is a good omen because it means your family will not starve. This could be taken metaphorically to mean that a Snake could never have a problem with his family starving because he is such a great mediator, making him good at business. Or it could mean that a Snake would be willing to sacrifice his possessions, something the Snake has a lot of, in order to pay for his family's food. Any way it is interpreted is representative of the Snake's character and is a measure of the value he puts on his material wealth. The Snake is keen and cunning, quite intelligent and wise.
