A conventional conforming loan is any loan that has terms and conditions that have established guidelines established. Fannie and Freddie Mac (the two leading loan agencies) decide what the minimum and maxium will be for each year. You can obtain a maximum loan amount that is 50% higher in Guam, Alaska, Hawaii, and the virgin islands.  A conventional conforming loan is smaller than a jumbo loan since the max you can take out is $417,000. These Loans are much more common than jumbo loans, so are generally easier to obtain.
