I have a real estate salesperson license in Maryland that is expired but I could reinstate it. I have no plans to invest in MD and I live in California.
Can I access the MLS nationwide with my Maryland license or should I get the license in California/ whatever state I would plan on investing in?
no, and no, and I think you should really evaluate your end goals because it seems like you are all over the place. You need clarity and focus more than a real estate license
