Selling an occupied rental comes with one detail that trips up more landlords than almost anything else: the tenant’s security deposit. Handling the security deposit when selling a rental property is not optional paperwork you can skip or handle informally with a handshake between buyer and seller.
Illinois law spells out exactly what has to happen, and getting it wrong can leave both the outgoing and incoming landlord financially exposed long after closing.
This guide walks through the mechanics of transferring a security deposit when selling a rental property in Illinois, the documentation you should keep, and the mistakes that most often turn a routine closing into a dispute months later.
The Short Answer: The Deposit Transfers With The Property

When you handle a security deposit when selling a rental property, the deposit does not stay with you as the seller. It transfers to the new owner at closing, along with any interest that has accrued on it.
Under the Security Deposit Return Act, 765 ILCS 710, both the outgoing landlord and the incoming landlord share responsibility for making sure the tenant’s money is handled correctly through the transition.
According to Illinois Legal Aid Online, when a rental property is sold, both the old and new landlord are responsible for the tenant’s security deposit. The tenant does not lose their deposit simply because ownership changed, and the new owner does not get to treat the property as a blank slate with no obligation to that money.
Why This Matters More Than Sellers Expect
Landlords selling an owner-occupied home rarely think twice about closing paperwork beyond the standard disclosures. A security deposit when selling a rental property is different because it involves a third party’s money, held in trust, governed by a specific statute with real penalties attached for getting it wrong.
If the deposit is not properly documented and transferred, the tenant has legal recourse against either landlord, and sometimes both. This is precisely why handling the security deposit when selling a rental property correctly protects you even after you no longer own the home.
A seller who walks away from closing without documenting the deposit transfer can still be pulled into a dispute the tenant files against the new owner months later.
What Exactly Has to Transfer?
Properly handling a security deposit when selling a rental property means transferring more than just the dollar amount. Here is what a complete transfer should include.
#1. The full deposit amount. This should match exactly what the lease states the tenant paid, not an estimated or rounded figure.
#2. Any accrued interest owed. Illinois requires landlords of buildings with 25 or more units to pay interest on deposits held longer than six months under the Security Deposit Interest Act, 765 ILCS 715. If interest applies to your property, it needs to be calculated and included in the transfer, not left for the new owner to sort out later.
#3. A written record of the deposit amount and date received. This protects both landlords if a dispute arises about what was actually collected.
#4. Documentation of any deductions already made. If a portion of the deposit was previously withheld for a documented reason, that record should transfer along with the remaining balance.
#5. The tenant’s original lease terms regarding the deposit. Some leases specify conditions for deductions, and the new owner needs to know those terms to remain compliant.
Every one of these pieces matters because a security deposit when selling a rental property is treated by Illinois law as the tenant’s money held in trust, not a line item the seller can simply keep or ignore.
How the Transfer Actually Happens at Closing
In practice, the transfer of a security deposit when selling a rental property is handled through the closing paperwork, typically as a credit to the buyer at the closing table. The seller does not write a separate check to the tenant.
Instead, the amount of the deposit, along with any interest owed, is deducted from the seller’s proceeds and credited toward the buyer, who then formally holds it on the tenant’s behalf going forward.
This structure only works cleanly if the deposit amount is documented accurately before closing. A title company or closing attorney handling the transaction should be told the exact deposit figure early in the process so it can be built into the settlement statement.
Sellers who wait until the final days before closing to mention a security deposit when selling a rental property often create last-minute confusion that can delay the transaction.

Documentation Every Seller Should Keep
Because a security deposit when selling a rental property can become the subject of a dispute even after you have sold the home, keeping clear records protects you long after you have moved on. At minimum, sellers should retain the following.
#1. The signed lease showing the original deposit amount. This is the baseline document that proves what the tenant actually paid.
#2. Bank records or receipts showing the deposit was received and held. This demonstrates the deposit was not commingled improperly or spent.
#3. A copy of the closing statement showing the deposit credit to the buyer. This is the single most important document proving the transfer actually happened.
#4. Any written communication with the tenant about the transfer. A short notice informing the tenant that the deposit has been transferred to the new owner, along with the new owner’s contact information, creates a paper trail that protects everyone involved.
#5. Records of any prior deductions from the deposit. If money was withheld before the sale for damage or unpaid rent, keeping the itemized statement and receipts protects the seller if the tenant later disputes the remaining balance.
Sellers who keep this documentation rarely run into problems. Sellers who treat a security deposit when selling a rental property as an informal handoff are the ones who end up fielding calls from a tenant’s attorney after the sale is long closed.
What Happens If the Deposit Isn’t Transferred Correctly?
This is one of the most commonly searched questions tied to the topic, and the honest answer is that both landlords can be exposed.
Under 765 ILCS 710, a landlord who fails to comply with the statutory deposit requirements can face liability for double the deposit amount, plus court costs and attorney fees, if a court finds bad faith involved.
If a security deposit when selling a rental property is never actually transferred, or if the amount transferred does not match what the tenant is owed, the tenant can pursue either the old landlord, the new landlord, or both once the lease ends and the deposit is due back.
This is precisely why documentation at the time of sale matters so much. A seller who can point to a clear closing statement showing the transfer occurred is in a far stronger position than one relying on a verbal agreement with the buyer.
Does Chicago Have Additional Rules?
If your rental property sits within Chicago city limits, the Chicago Residential Landlord and Tenant Ordinance imposes stricter requirements around deposit handling than state law alone.
The RLTO requires itemized accounting for any deductions and specific timelines for returning deposits, and Chicago landlords face heightened liability for noncompliance compared to the baseline state statute.
This means a security deposit when selling a rental property located inside Chicago needs to account for both the statewide Security Deposit Return Act and the additional local ordinance.
A seller working with a knowledgeable title company or attorney should confirm which rules apply based on the property’s exact location before finalizing the closing paperwork.
What If the Tenant Already Owes Money Against the Deposit?
Sometimes a landlord selling an occupied rental has already documented damage or unpaid rent that would justify a deduction from the deposit. In this situation, a security deposit when selling a rental property should still transfer in full to the new owner, along with the documentation supporting the planned deduction.
The seller should not unilaterally deduct the amount and hand over only a reduced balance without clear, itemized proof, since doing so can trigger a dispute if the new owner or the tenant disagrees with the deduction later.
The cleanest approach is full transparency. Transfer the complete deposit amount, hand over every piece of supporting documentation, and let the new owner make the final determination about deductions once they take over as landlord of record.
Why This Process Looks Different With a Cash Buyer
Retail buyers purchasing a home to live in are often unfamiliar with the mechanics of a security deposit when selling a rental property, since most residential purchases do not involve an existing tenant at all.
This unfamiliarity can slow down a transaction, since the buyer’s lender and title company may not be accustomed to structuring a deposit credit into a standard purchase agreement.
An experienced cash buyer who regularly purchases occupied rentals handles this differently. At Sell To Dynasty, we account for the security deposit when selling a rental property as a standard part of our evaluation and closing process, since we buy tenant-occupied rental properties throughout the Chicago Southland on a regular basis.
We know exactly how the deposit credit needs to appear on the closing statement, and we work with a title company familiar with these transactions, which removes one more point of friction for landlords who simply want a clean, documented handoff.

Common Questions Landlords Ask
Do I get to keep the security deposit if I sell the property?
No. The deposit belongs to the tenant, not the landlord, and it must transfer to the new owner at closing along with any interest owed.
What if I already returned the deposit before selling?
If the tenant has already moved out and the deposit was properly returned or applied to damages before you list the property, there is nothing left to transfer. This situation only applies to a security deposit when selling a rental property that still has an active tenant in place.
Can the buyer refuse to accept the deposit transfer?
Not really, if they intend to purchase an occupied property with an active lease. The lease and the associated deposit obligations transfer together under Illinois law, and a buyer purchasing a tenant-occupied rental is agreeing to step into that role.
Who is liable if the deposit is mishandled after the sale?
Both the old and new landlord can potentially be held liable, depending on when the mishandling occurred and whether proper documentation exists showing the transfer took place correctly.
Does the tenant need to be told the deposit was transferred?
Yes, as a best practice. While the exact notification requirements can vary, informing the tenant in writing of the new owner’s identity and confirming the deposit transfer protects both landlords and gives the tenant a clear point of contact going forward.
Getting the Deposit Transfer Right Protects Everyone
Handling a security deposit when selling a rental property correctly is a small piece of a larger transaction, but it is one of the pieces most likely to cause a dispute if it is overlooked.
Documenting the amount, transferring it properly at closing, and keeping clear records afterward protects the seller from liability long after the sale is complete, protects the buyer from inheriting an undocumented obligation, and protects the tenant’s right to their own money.
