If you are thinking about starting your own rehab center, never lose sight that it is all about location. Before making any other business decision, you will need to conduct a market study. This means picking the region for your treatment center that offers the best chance for success.
Think about whether there are many rehabs in a certain region and ask yourself if there is really a need for another one. What are the local zoning laws? What are local leasing costs or real estate values? Is there a target market for your services?
