Doubt it, you can hire an agent, who actually writes the contracts on the properties you buy. To be sure, check with your state’s Real Estate Commission.
It may make you look more creditable. I don’t know if you NEED it, but it may look better to clients if you did….. or just hook up with someone who has one!! Good Luck.
You may not have to have a real estate license but it would probably be an advantage for you if you have one.
