Payment frequency determines cash flow timing and late fee trigger dates. While monthly payments are standard, some leases require quarterly or annual prepayment, which dramatically changes the tenant's working capital requirements. A $300,000 annual rent paid quarterly means $75,000 due at once instead of $25,000 monthly -- a threefold increase in single-payment exposure.
Specified in the "Rent" or "Payment" section, usually stating "due and payable in equal monthly installments on the first day of each calendar month." Some industrial leases specify quarterly payments.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the payment frequency from your lease PDF. The AI searches for the field name and common aliases like "Installment Period" across all pages of the document, then assigns a confidence score based on OCR quality and extraction certainty. Fields with lower confidence are flagged for human review.

Escalation Type

Fixed Escalation %
The static percentage by which rent increases annually, if applicable.

Yes, the vast majority of commercial leases require monthly rent payments due on the first of each month. Some shorter-term or industrial leases may use quarterly payments. Annual prepayment is rare but does exist in certain international markets.
Rent is almost always due on the first calendar day of each month. Most leases include a grace period of 3 to 5 days before late fees apply, though some landlords charge late fees immediately after the due date.
