Well, I have all the answers you need. I have been looking to purchase an existing bar/tavern and finally after 2 years, located one that actually has verifiable positve cash flow. Basically, you can employ (for free) the help of some business brokers to send you daily emails with new listings for bars/taverns. At this point, you should know what city, location, size, type of bar you want. (ie, drinking/dive bar, lounge, etc). You should already have extensive experience in the bar industry. Experience as in bartending/serving, managing...not experience as a bar patron. Owning a bar is heavy duty work long hours involved.
Once you locate a bar, you should begin preparing a business plan. There are just so many things you will need to do. If you make an offer an it was accepted, make sure the purchase agreement covers you. By this I mean, make sure the offer is contingent upon you having the business professionally valuated(to ensure the business is even worth the purchase price) and contingent upon you receivng business financing to fund the acquisition.
Business funding for a bar/tavern is a story in itself. Even if you have great credit, banks will rarely offer you a significant amount of financing, if any. As a result, your options are really limited. You can always request the seller to finance a portion of the price and you put down the rest. Or, look for private investors. This can be structured by using debt-financing or equity financing. From my experience, it is very difficult to secure a private investor. To this day, I have not found any to risk their money on me and a bar busines.
It is not impossible, you just have to be persistent. More than likely, you will have to offer some equity share to the private investor. Your best bet, is to get the seller to finance as much as you can get him to finance and get a small microloan and then put some of your own money. There are many creative ways but it's like putting a puzzle together. Good luck and hope this helped.
