Wholesaling real estate provides an opportunity for someone to build income with little capital or credit. All it requires is ambition and some specialized knowledge. The more ambition you have, the more money you will make. Wholesaling does not require a real estate license. A license is not required to buy or sell any property that you have an equitable interest in. That interest can be a contractual interest (you have the property under contract) or you actually own or have title to the property.
