There are so many aspects to look into when purchasing a business:  Location, Price, Condition, History of the business, Expansion potential, etc.  No matter what, it will likely be a headache for most.  Each step, from financing to agreement upon every small detail can be monotonous and even frustrating.

Keep in mind that most sellers will work closely with you, so be sure to keep an open line of communication with them during this entire process.  Seek reputable legal counsel from the area in which you are buying.  Be certain to have a CPA look at your numbers.  Many times, there will be some tiny detail that threatens or even kills the deal.  Try to work through each of these issues slowly and logically.  Remember, this purchase is your future!  So make it worthwhile by acquiring all the necessary information to succeed.
