Landlord's right to demand all future rent immediately upon a lease default.
By Angel Campa, Founder · Updated March 2026
An acceleration clause converts a monthly rent obligation into an immediate lump-sum demand upon default. On a lease with 60 months remaining at $25,000/month, acceleration creates a $1.5 million demand. While courts in many jurisdictions require landlords to mitigate damages by re-leasing, the clause shifts the burden to the tenant to prove mitigation. This is one of the most punitive remedies available to landlords.
Found in the "Remedies" or "Landlord's Remedies" section. Look for language about the landlord's right to "accelerate" rent or demand "the present value of all rent for the balance of the Term." May also reference a discount rate for present value calculations.
Lextract uses a combination of AWS Textract OCR and Claude AI to identify and extract the acceleration clause from your lease PDF. The AI searches for 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.
Monetary Cure Period
The number of days allowed to remedy missed financial payments after notice.
Non-Monetary Cure
The number of days allowed to remedy operational or physical breaches after notice.
Liquidated Damages
A predetermined penalty fee assessed for specific breaches of the contract.
Late Fee %
The penalty percentage applied to overdue rent payments.
Holdover Rate
The multiplier applied to base rent if the tenant remains post-expiration.
Enforceability varies by state. Many jurisdictions require the landlord to reduce the accelerated amount to present value and credit the tenant for any mitigation (re-leasing). Some states limit acceleration to actual damages. Courts generally disfavor double recovery, so the landlord cannot both accelerate rent and re-lease the space without providing a credit.
Typically, accelerated rent equals the present value of all remaining rent payments, discounted at a specified rate (often the Federal Reserve discount rate or a contractual rate). Some leases use a simpler formula: total remaining rent minus a fixed discount. The present value approach is more favorable to tenants.
