A sharp improvement in the availability of jumbo loans helped drive overall credit conditions in home financing to the loosest levels in nearly a decade.

As of March 2017, the Mortgage Credit Availability Index, a standardized quantitative index that is focused only on mortgage credit, came in at 183.4.

The latest index — which is based on several eligibility factors like credit score, loan type and loan-to-value ratio — was the highest since roughly mid-2008.
