Conforming loan limits for 2007 will remain the same as 2006 which is currently $417,000 for single family homes according to the Office of Federal Housing Enterprise Oversight.

The 2007 Fannie Mae loan limit for two-family loans is $533,850. Loans above this loan amount for duplex is considered "Jumbo loans" and have higher interest rates.

However, even if your mortgage requirements fall outside of Fannie Mae's limits, there are now dozens of innovative new mortgage products which allow you to keep payments low even if you are in "jumbo" territory.
