As government tries to grapple with the economic crises the FHA loan limits have changes 3 times in recent months.  Once they were decreased and twice they were increased.  At the present time the FHA Mortgage Limits in Denver are at $406,250 and the new 1-family limit for Boulder County is $460,000.  Limits are higher for 2, 3, and 4-family properties.

FHA provides a website with the current Mortgage Loan limits for each county in the country.  You can find it here.
