New Mexico Late Rent Fee Rules: Limit, Grace Period and Notice
New Mexico caps late rent fees — ≤10% — with the grace period set by the lease under NMSA §§ 47-8-15, 47-8-37. Set the rule once on the lease and the fee posts itself the day it is allowed.
The cap, the grace period and the wording all matter. The rule on each card is New Mexico's statutory position — your lease can be more lenient, never harsher.

The amount, within the New Mexico limit10% of the rent per rental period.NMSA §§ 47-8-15, 47-8-37
✓
The grace periodNone required by New Mexico statute; state the one you give (3–5 days is customary) so the tenant knows the date.
✓
When it is assessedThe day after the grace period ends, once, for that rent period.
✓
How it is chargedAdded to the ledger as a separate line, never folded into rent — it stays visible and cannot be disputed as a rent increase.
✓
No fee on feesA late fee never accrues interest or a second fee; returned-payment charges are separate and must also be in the lease.
✓
Same rule for every tenantApply the lease rule uniformly; waiving it for one tenant and not another invites a fair-housing complaint.auto-applied
How it works
1 · Set the rule on the leaseLease → late fee: amount or percentage, and the grace period. The New Mexico limit above is the ceiling.
2 · Rent goes lateThe day after the grace period the fee posts to the tenant's ledger as its own line, with the date.
3 · Collect or waiveThe tenant pays it with rent (autopay picks it up); you can waive any fee from the ledger and it is logged.
New Mexico late fee FAQ
How much can a New Mexico landlord charge for late rent?
10% of the rent per rental period (NMSA §§ 47-8-15, 47-8-37).
Is there a grace period in New Mexico?
None set by statute — the lease controls.
Can I charge a daily late fee?
Daily fees are struck or capped in most states because they read as a penalty rather than a cost; one fee per rent period, stated in the lease, is the enforceable form — and the total must stay within the New Mexico cap.
Does the late fee count toward an eviction notice?
The pay-or-quit notice can include late fees the lease allows; the in-app notice lists rent and fees as separate lines with the total.
What if the lease says nothing about late fees?
Then you cannot charge one. Add the clause at renewal — a mid-term notice does not create the right.
