I got into the coffee business by buying a very busy shop with a SBA guaranteed loan. I was turned down by three banks but the fourth one okayed the loan. Even though the first three banks were looking to get SBA guarantee, they required substantial collaterals, which I didn't have. However the fourth bank's lending officer took a look at the shop's tax returns, ran the numbers, visited the shop and okayed the loan in less than two weeks. The presentation, paper works and business plan were exactly the same for all four banks. The first bank that I applied with is the bank that the shop does business with, they knew the business was raking money hand over fist, and the purchasing price was way low, plus I knew the lending officer pretty well, but they still turned down the loan. The other two were all local banks, where as the fourth bank that took a chance on me, is an out of town bank. You just never know.
By the way borrow on the high side, and ask for a 5 to 7 year loan, and be conservative but realistic with your numbers.
Good luck.
