Is my niche too big?

Hello there gorgeous! Thank you for your help 🙂

I’m wanting to launch my coaching business and wrap it up with all my passions: home, mind & body. Creating a beautiful lifestyle which for me includes the home you live in and the body you live in.

I love renovating, flipping homes, and thought I could integrate this into my business.

Suggestions please re niche and this idea? Is it too big a scope for marketing?
