Hi . Your essay has some good arguments and you have been very effective at using rich vocabulary as well. However, I would suggest the following for you to look at:
The First and foremost reason to start a new business is that businesses generate profits.
You should consider using an alternative phrase instead of repeatedly stating "thus it is better to own a business than a home", as it is already implied.
Another worth mentioning point is that running a business gives you an experience which is not achievable through other means. You get to look at things from a very different perspective than you used to before.
This is a very vague statement, which you could back up and support more concretely through examples.
Other than that, you have done a great job. Unfortunately, I am unable to provide you with an indication as to where your essay would lie in terms of "bands" as I am not too familiar with the IELTS. But I wish you the best of luck!
