Real Estate Development Business Plan
Let the government know about you. Unless the government recognizes you, you're not officially a business. It's time to register your new company with the government by filing an article of incorporation. This document lists the name of your business, its purpose, its corporate structure, any details about stocks and similar information. If you're not registering as a corporation, you simply need to register the name of your business. That could even be your legal name "Doing Business As." Depending on your branding, you also might want to seek a trademark.
But don't confuse simple wording and formats with simple thinking. The reason you're keeping it simple isn't because you haven't developed your idea fully. You're keeping it simple so you can get your point across quickly and easily to whoever's reading it.
