These loans are for those borrowers who wish to borrow more funds than a Conforming loan limit allows (greater than $484,350 for a single-family property).  Jumbo loans are offered for both Fixed Rates and Adjustable rate mortgages.  Generally, the underwriting is stricter and requires more documentation.  The qualifying total debt to income ratio typically cannot exceed 43%.  In some cases, two appraisals are required.
