I  want  to  know  that  what  is  the  difference  between  "Joint 
Venture  loan  and  Venture  Capital  loan"?

A loan is a loan is a loan. Joint ventures are a type of business
organisation involving 2 or more partners. Venture capital firms are a
type of business. But a loan is what the NOTE says it is. Any
differences should be apparent by comparing the disclosure statements
that are required with such transactions. If you have 2 organisations
willing and able to provide money, the terms should be the most
important thing effecting your decision. Additionally, the character
of the people you do business with should mirror the standards that
you set for yourself or your company.
