When a payment is “late” vs. when it’s reported
-
Your mortgage payment is technically late as soon as it’s not paid by the due date (usually the 1st of the month).
-
Most lenders give a grace period (often 15 days), so if you pay by the end of that grace period, you avoid a late fee, but the payment is still considered late by the servicer after the due date.
-
However, that late payment does not show up on your credit report unless it reaches 30 days past due.
When credit bureaus see the late mark
-
Creditors (mortgage servicers) generally cannot report a payment as “late” to the credit bureaus until it is at least 30 days past the due date.
-
For example, if your payment is due on the 1st, it usually won’t be reported as late until around the 31st (or 30th in a 30‑day month).
-
Once reported, a 30‑day late mortgage payment can stay on your credit report for up to 7 years and may significantly lower your credit score, especially if your score was high to begin with.
What happens before 30 days
-
A few days or even 1–2 weeks late usually only triggers a late fee (if outside the grace period), but not a credit report ding.
-
The servicer may send late notices and may start calling or emailing to collect the payment, but they won’t report it to the bureaus until the 30‑day mark.
-
If you bring the payment current before 30 days past due, you can often avoid any negative impact on your credit.
After 30 days late
-
At 30 days late, the servicer reports the delinquency to the credit bureaus, and a “30 days late” status appears on your credit report.
-
The damage to your credit score increases as the delinquency grows: 60 days late is worse than 30 days, and 90 days late is worse still.
-
Around 36 days late, federal rules require the servicer to try to contact you about the missed payment; if it continues, they may send a Notice of Default and eventually start foreclosure proceedings.
Bottom line
-
A mortgage payment is late as soon as it’s past the due date (and possibly after the grace period), but it only hurts your credit once it’s 30 days past due.
-
If you can get the payment to the servicer before the 30‑day mark, you can usually avoid a negative credit report entry, though late fees may still apply.
