Calculate what a tenant owes for breaking a lease early — and your obligations as a landlord
Important
Florida requires landlords to make a good-faith effort to re-rent. You cannot collect both the ETF and full remaining rent — only actual damages.
When a tenant breaks a lease early, landlords are entitled to recover their actual financial damages — but the extent of that recovery depends heavily on your state's law and whether you have an early termination clause (ETF) in your lease.
Without an ETF clause, landlords can generally recover: (1) rent lost during the vacancy period, (2) reasonable costs to re-lease the property (advertising, cleaning, agent commissions), and (3) any difference in rent if the new tenant pays less. What landlords generally cannot collect is the full remaining rent on the lease if the property is re-rented quickly — that would result in a windfall.
Most states (approximately 38 of 50) require landlords to make a reasonable effort to find a new tenant after a lease break. This is called the duty to mitigate damages. If you refuse to try to re-rent, a court will typically reduce the damages you can collect — even if your state doesn't technically require mitigation. Documenting your mitigation efforts (listings, showings, applications received) is essential if you plan to pursue the tenant for damages.
The cleaner solution is to include a well-drafted early termination fee clause in your lease. An ETF clause sets a specific amount the tenant owes if they break the lease, regardless of how quickly you re-rent. This provides certainty for both parties and avoids costly litigation over actual damages. Most courts enforce ETF clauses as long as they represent a genuine pre-estimate of damages — typically 1–3 months' rent is considered reasonable. Setting the ETF at the full remaining rent is likely to be voided as a penalty clause.
Certain circumstances allow tenants to terminate early without penalty: active military deployment (SCRA), uninhabitable conditions, domestic violence (most states), landlord harassment, or landlord's material breach of the lease. These are exceptions — a tenant moving for a new job or buying a house still owes damages.
Can I keep the security deposit if a tenant breaks the lease?
You can apply the security deposit toward unpaid rent and damages from the lease break, but you must follow your state's security deposit return laws — typically returning any unused portion within 14–30 days with an itemized statement. You cannot simply keep the entire deposit as a lease-break penalty.
What if the tenant just stops paying and abandons the unit?
Abandonment is different from a formal lease break. You must first determine the unit is actually abandoned (most states have a specific process), secure the property, document its condition, then pursue the tenant for damages. Do not enter and re-lease without following abandonment procedures — you could face liability.
Does an early termination fee count toward the security deposit cap?
In most states, an ETF is separate from the security deposit and does not count toward security deposit caps. However, it is a distinct contractual obligation, not a deposit. California, for example, prohibits collecting an ETF that is more than the actual damages suffered.
What is the strongest language for an ETF clause?
A solid ETF clause specifies the exact amount (or formula, e.g., two months' rent), states it covers both the administrative costs of re-leasing and anticipated vacancy, requires written notice from the tenant, and confirms that payment does not release the tenant from the duty to continue paying rent until a new tenant is found.
Can I sue a tenant who breaks a lease in small claims court?
Yes — lease break damages are a common small claims case. Most states have small claims limits of $5,000–$10,000. If damages exceed that, you would need to file in civil court. Document everything: the signed lease, the break notice, your re-leasing efforts, advertising costs, and the new lease (showing the gap in income).
