Mortgage lending standards are tightening to the point that many homebuyers need “pristine” credit histories, according to a new study cited by Fortune and Yahoo News. The report says changes in underwriting practices reduce delinquencies and defaults, but also make mortgage qualification more difficult for a broader range of borrowers.

Both outlets note that this stricter environment coincides with a slowdown in housing transactions. Yahoo News highlights that home sales are heading toward a 31-year low, reflecting how harder-to-qualify borrowers can contribute to weaker demand. Fortune similarly frames the issue as a trade-off: lower credit risk for lenders and fewer approvals for potential buyers.

While the outlets focus on different implications—Fortune emphasizes the credit-standards shift and its effects on delinquencies, and Yahoo News underscores the impact on market activity—both describe the same overall trend: lending criteria have become more restrictive as home sales decline.
