Trying Out A Business First

I am thinking of running an online business (a subscription service) as an individual initially to gauge its viability. If it works, I plan to then do it as a proper 'full-fledged' registered business entity. If I take this route, will I then be able to sell the business to myself and also give a loan to the business? Are there any pitfalls?



Hope to get some directions in this regard. Many thanks in advance
