I have worked in this small business and others like it, so I know how to work the store itself and I know the potential it has to grow. I have bad credit and I have no capital, I don't own a home or have any investments, so Im not sure if buying it is even possible. I worked for a man who owned a chain who also had nothing and he told me he worked the store and gave a percentage of the profits, is that an option for small business or is that only applicable for franchise/corporate?
You would probably either need a bank loan or find an investor who will provide you with the money to buy the place. You can find out if the banks offer a small business loan to you first. You could also find out if you could get a start-up grant from a local bank or organization- maybe approach (become a member in) the Chamber of Commerce. There might also be the option of crowd-funding.
Either way, you will need to present a good business plan and strategy.
