First I think you have to figure out exactly what it is you're after. You mentioned being a good instructor, then you mentioned a career change. Are you wanting to figure out how to become a good martial arts instructor (difficult) or are you wanting to figure out how to make a living as a martial arts instructor (even more difficult)? While the two are in no way mutually exclusive, they do have different goals and so require a bit of a different mind and skill set.
That is incorrect. I've run my own dojo for close to 15 years without any collateral and without much business sense. How long have you been running your dojo, or are you just guessing?
Well if you want to start your own place you need collateral in addition to all the stuff you mentioned. You also have to have a business sense.
