Sometimes knowing what not to buy may be just as important as what to buy.
From BlueMauMau you should see this list of the 25 worst franchises to buy in 2011. The list is based upon failure rates of SBA loans only (with 50 or more disbursements). Eight franchises have over a 50 percent failure rate on getting the SBA loan repaid. It would appear you definitely need to think twice if you are looking at franchises on this dubious list.
