One important question that a buyer is likely to have is, are you willing to finance at least part of the deal? This is a very fair question — during periods of tight bank credit like we've been experiencing since 2008, seller financing is common in many, many business sales. Even as the credit crunch eases, sellers are likely to provide at least some of the financing in a majority of business sales.
Sellers are often willing to do this because they can usually postpone some of the capital gains tax on the sale if they comply with IRS requirements regarding installment sales. Buyers are relieved because business acquisition loans from banks are still rather hard to come by.
