Baking is my passion

Hi all,

I own a small bakery near my home. Baking is my passion and I really enjoy doing it. I always keep trying new recipes and my customers also demand it. My bakery is going in a profitable manner and I have plans to renovate it.
But I do not have all the required funds at the moment. So, I am planning to take up a mortgage and complete the renovation works. After doing a research, I have decided to take up a self-employed mortgage.

What are the risk factors related to this?
And I want to do something different for my new cake shop. I would love to hear some suggestions from you all regarding this.
