I've owned a small pizzeria restaurant for over 15 years now, and before I bought it I put a lot of research into it. There's a lot of factors involved. What kind of restaurant, is there any good locations available, do you even need a "good" location (if it was 90% delivery for example, maybe location isn't a huge factor), what is the market like and is it already saturated, what is the competition like, do you want to have full service with alcohol sales? Who are your target market and are they living in high density around your local neighborhood? Those are good questions to ask yourself and research on where to start. Also what's the employment rate in your local neighborhood/state currently? Another option, if you do a bit of research and know kind of answers to the above questions, is "is there a place similar to what I want already for sale." This can be a big opportunity to either take an existing business that isn't doing well, getting a good price on it, and turning it around, or even to completely re-brand an existing place and turn it into your own. Hopefully those help you get started on your journey. If you have any further questions, of course, don't hesitate to let me know.
