This will greatly depend on the online real estate school you are enrolled in, as well as how quickly you are able to complete coursework. On average, completion of online real estate education can take students anywhere from six weeks to three months. How long it will take also depends on the amount of time you can give to the online classes. If you need to work during your studies, keep in mind that it may take the full three months or longer. It's also important to remember that once you finish real estate school, you'll still need to pass the licensing exam and complete any further state requirements before fully beginning your real estate career. This may take some time as well and should be accounted for in your timeline.
