Pre-approval FAQ

How long does a pre-approval last?
Most letters are valid around 60–90 days. Lenders can refresh with updated pay stubs/bank statements; big changes may require re-underwriting.
Does shopping multiple lenders hurt my credit?
Rate-shopping within a short window is typically treated as one inquiry. Group your applications to minimize impact.
What DTI should I target?
Lower is better. Many approvals fall under common caps for back-end DTI; improving your debt or increasing down payment can help.
