Bankruptcy, foreclosure & major derogatory credit
A prior major credit event does not mean “no conventional loan.” The event type, completion date and agency rule determine the waiting period.
Fannie DU examples
Fannie's current DU analysis generally treats a non-Chapter 13 bankruptcy inside four years as ineligible. A Chapter 13 discharged within two years or dismissed within four years is generally ineligible. Foreclosure generally carries a seven-year period, with a documented extenuating-circumstance path that can reduce the foreclosure period to three years when all applicable requirements are met.
Short sale / deed-in-lieu / mortgage charge-off
These events have their own agency waiting-period rules and should not automatically be labeled “foreclosure.” Correct classification matters because the waiting period can differ.
