You say that you will charge to record bands. A studio or office for your own use is one thing, but receiving clients is a business of a different sort, at least from your neighbors’ and town perspective. I suggest you (quietly) check local laws, history and sentiment before you invest much. Even if the sound doesn’t travel beyond your lot (and it had better not!), neighbors might object to strangers parking, loading/ unloading, “musicians” in general, anything. Localities and neighbors vary greatly in their laws, prejudices and tolerance. So might your experience. Then there’s the matter of insurance, including liability, in a business environment. Check with your provider.
