To become licensed in Michigan as a real estate salesperson you must be 18 years old, complete a 40-hour state approved Prelicensing course on real estate fundamentals, and pass the state exam. You do not need to be a Michigan resident so long as you plan to work under a broker who is licensed in Michigan.You must complete the Prelicensing course before applying for your license. Your school will issue you a certificate of completion and submit the certificate to the State of Michigan. You have 36 months from the date of completion to apply for your license. After that, you will need to take the course again.
