What is the starting salary for a house flipper?

Working as a 'house flipper' is generally an entrepreneurial venture, which means that you buy the house, you flip the house.

Whatever you earn -- or lose -- is the difference between what you pay and what someone else pays you for the house.

In other Words, unless you're working with someone else's money, and/ or being paid by someone to flip houses -- rates are apparently negotiable -- there is no standard for what you can expect to earn.
