The Lease Problems That Most Often Disrupt Dental Practice Sales
Several recurring lease issues can surface at any stage of a transaction and can delay closing, reduce price, or collapse the deal entirely.
- Landlord consent and assignment, which control whether the landlord must approve the transfer and on what standard.
- A personal guaranty that survives the sale, which can leave the seller responsible for rent years after retirement.
- Too little remaining term for buyer financing, because a short lease can prevent a buyer from obtaining an acquisition loan.
- Restrictive use and exclusivity clauses, which limit what the buyer can do with the space and cap growth.
- Change-of-control provisions triggered by a corporate or private-equity buyer, which can require fresh landlord approval or enable recapture.
- Demolition, relocation, or recapture rights, which can give the landlord the ability to terminate the lease rather than consent to a transfer.
- Assignment versus new lease friction, because a new lease lets the landlord reset rent to market rates and impose new guaranty terms.
These issues often surface late during the buyer’s lender diligence or when the landlord is formally contacted, which usually occurs well after the LOI is signed. The seller, not the buyer, benefits from driving resolution early while competition among buyers still exists and the seller retains negotiating leverage. McLerran & Associates audits the lease before the practice is listed, so these issues are identified and addressed while the seller still controls the narrative.

Landlord Consent And Assignment Standards In Dental Office Leases
Most commercial leases require the landlord’s written consent before the tenant’s interest can be assigned to a new entity. In a dental practice sale, the landlord must formally approve the transfer of the lease to the buyer before closing can occur. In commercial leases, the two most common landlord consent standards are the unqualified “sole and absolute discretion” clause and the qualified “shall not be unreasonably withheld, conditioned, or delayed” clause, with the reasonableness standard being the most common restriction. Sole and absolute discretion gives the landlord an effective veto, while the reasonableness standard limits refusal to concerns such as the buyer’s creditworthiness or intended use.
The distinction can be significant. A lease permitting consent to be withheld in the landlord’s sole and absolute discretion is, in practical terms, a lease the tenant may not be able to transfer. Even under a reasonableness standard, state law varies. California courts have held that where a commercial lease requires consent but states no standard, consent may be withheld only on commercially reasonable grounds, while a majority of jurisdictions, including Indiana, still allow a landlord to refuse consent without explanation absent limiting lease language.
The economic consequence of a stalled landlord can extend beyond inconvenience. Landlord lease assignment disputes are among the most common causes of timeline extensions on dental practice acquisitions, adding weeks to a closing process that already runs 60 to 120 days. A delayed closing can trigger lender deadlines, cause a buyer to re-trade the price, or prompt the buyer to walk away.
The practical step is to review the lease and any consent language before listing. Make closing expressly conditional on written landlord consent in both the LOI and the purchase agreement, and agree upfront on who pays the landlord’s review fees, which can run several thousand dollars. McLerran & Associates builds landlord consent into the deal timeline and LOI protections rather than treating it as an afterthought. For a deeper look at how LOI terms can protect the seller, see Dental Practice Letter of Intent: Key Terms to Know.
Personal Guaranty Release And Post-Sale Risk
A personal guaranty is a separate contract from the lease in which the practice owner personally promises to cover the tenant’s obligations if the tenant defaults. It can be the seller’s sharpest post-sale exposure. A landlord’s consent to assignment is not, by itself, a release of the original tenant, so the seller remains liable unless the landlord expressly releases that party in writing.
Without an express release, a selling dentist can remain responsible for the buyer’s rent years after retirement. That exposure can include base rent, additional rent such as tax and operating expense escalations, repair and restoration obligations, and the landlord’s legal fees. A seller’s guaranty exposure can extend past a buyer assignment to cover renewals, extensions, and amendments the seller never signed, because many guaranty forms state the guaranty applies to the lease “as it may be amended, extended or renewed.”
Three primary negotiation asks often make sense, listed in order of preference.
- Express release at closing, where the landlord signs a written release, ideally conditioned on the buyer or its owners providing a replacement guaranty.
- Burn-off or declining guaranty, where the seller’s liability terminates after a defined period of on-time buyer payments, commonly 24 to 36 months, with no uncured defaults at the time of release.
- New lease in the buyer’s name, where the landlord accepts a surrender of the seller’s lease and signs a new lease directly with the buyer, which extinguishes the seller’s obligation entirely.
An unreleased guaranty functions as a contingent liability that follows the seller into retirement and can complicate personal financing and estate planning. The guaranty should be addressed in the letter of intent, which at minimum should identify the guarantor and state whether the guaranty will be unlimited, capped, or reduced or released over time, because a disagreement over whether a personal guaranty is expected can kill a deal.
The practical step is to demand release language in the LOI rather than waiting until closing. If the landlord refuses an outright release, negotiate a burn-off tied to buyer performance. McLerran & Associates negotiates this on the seller’s behalf as part of the LOI and deal-structuring work. Sellers should consult their attorney on jurisdiction-specific requirements, because state law governs guaranty enforceability and release mechanics.
Remaining Term, Renewal Options, And Lender Expectations
The buyer’s lender treats the office lease as part of the collateral for the practice acquisition loan. A practice’s goodwill, which can represent the majority of the purchase price in a dental acquisition, often ties to a physical address because patients return to a location, not only to a dentist’s name. A dental office lease with about 2 years remaining and no assignable renewal options can prevent financing outright rather than merely worsening pricing or terms.
For SBA 7(a) loans, which are the most common financing vehicle for dental practice acquisitions, the lease term, including renewal options exercisable only by the borrower, generally must equal or exceed the loan term. A 10-year SBA 7(a) acquisition loan usually requires 10 years of combined remaining term and buyer-exercisable options at closing. Renewal options count toward this requirement only if they transfer to the buyer, because options that are “personal to the seller” terminate upon assignment and do not satisfy the lender. Under SBA SOP 50 10 8.1, which takes effect October 1, 2026, these requirements are codified in the updated SBA rulebook.
The economic consequence can be direct. A short remaining term shrinks the qualified buyer pool, reduces competitive tension, and can put downward pressure on price. When a dental practice’s lease has only 2 years left with no extension option at the time of sale, the practice sale price can drop measurably. The lease term effectively becomes part of what the seller is selling.
The practical step is to confirm remaining term and renewal options before listing and verify whether those options are genuinely buyer-exercisable. If the term is short, negotiate an extension with the landlord before going to market or build the extension into the deal timeline. Attribute lender expectations to financing sources generally and confirm the specific calculation with the buyer’s lender in writing. For context on how real estate and lease decisions interact, see Selling a Dental Practice With Real Estate: What to Know.
Restrictive Use, Exclusivity, And Change-Of-Control Clauses
Restrictive use clauses limit what the buyer can do with the leased space. A clause stating “general dentistry only” can prevent the buyer from adding orthodontics, oral surgery, or other services, which can limit growth and reduce what a buyer will pay. A permitted use clause limited to “general dentistry only” can also prohibit a dentist from adding services such as orthodontics or oral surgery as the practice evolves. Exclusivity clauses, which prevent the landlord from leasing to a competing dental tenant, must be negotiated explicitly because they are not implied by the lease.
Change-of-control provisions add a separate layer of risk in corporate and private-equity transactions. Many commercial leases define a change in ownership of the tenant entity as an assignment, sometimes any transfer of a controlling interest, which means that selling the business via a stock or membership-interest transfer can still trigger the landlord’s consent requirement. In a corporate deal, the entity holding the lease may change hands as part of the management services organization acquisition, even when the clinical professional entity nominally remains in place. The lease’s change-of-control language may treat the structure as a transfer requiring landlord consent even when the parties assume the lease is undisturbed.
The practical step is to identify change-of-control language during the pre-listing audit. If a corporate buyer is likely, negotiate a consent or waiver path with the landlord before signing an LOI with that buyer. McLerran & Associates works both private-buyer and corporate or private-equity transitions in roughly equal measure, so the team reads these clauses through both lenses and structures the approach accordingly.

Seller Pre-Listing Lease Audit And State-Law Triggers
A pre-listing lease audit can cover several core items before the practice goes to market.
- Full lease and all amendments.
- Remaining firm term and renewal options, including whether options are buyer-exercisable.
- Assignment and consent language, including the consent standard.
- Personal guaranty terms, scope, cap, and burn-off provisions.
- Restrictive use and exclusivity clauses.
- Change-of-control triggers.
- Demolition, relocation, and recapture rights.
- Responsibility for landlord review costs and administrative fees.
State law and local market conditions can vary significantly. In California, Civil Code § 1995.260 provides that when a commercial lease signed on or after September 23, 1983 requires landlord consent to assignment but states no standard, the law reads in an implied standard that consent may not be unreasonably withheld. California sellers must also notify the Dental Board of California within 30 days of any change in practice ownership, and California SB 351, effective January 1, 2026, restricts private equity and hedge fund involvement in dental practices, including prohibitions on interference with clinical judgment and voiding of noncompete clauses in investor contracts. In Washington, HB 2548, signed March 25, 2026 and effective June 11, 2026, expanded the state’s healthcare transaction notice rule to include changes in majority ownership or control and transfers of a majority of assets, which can add a potential standstill period that pushes a seller past the purchase agreement’s outside closing date. Sellers should confirm jurisdiction-specific requirements with their attorney and CPA before listing.
The practical step is to complete the audit before the practice goes to market and pair it with a CPA-led valuation so lease risk is priced into the asking price rather than discovered in diligence. McLerran & Associates builds a diligence-grade, CPA-led EBITDA valuation, the kind that can hold up under buyer scrutiny and tends not to get re-traded, and reviews the lease alongside it. The firm’s roughly 85–90% transaction rate, versus an industry norm closer to 35–40%, reflects the difference that preparation can make. For context on deal structure, see Dental Practice Asset Sale vs. Stock Sale: A Seller’s Guide.
Purchase-Agreement Protections When Consent Is At Risk
Even a well-prepared seller can encounter a slow or difficult landlord, so the purchase agreement benefits from protections that keep the deal alive if consent is delayed or refused. Several provisions often play a central role.
- Closing condition, which makes landlord consent an express condition of closing so neither party is obligated to close without it.
- Defined timeline with deadlines, which provides a cure or extension period if consent is delayed, with clear consequences if the deadline passes.
- Allocation of landlord fees, which clarifies who pays the landlord’s review costs and any pre-closing obligations.
- Fallback provisions, which define a path if consent is refused, such as a new lease in the buyer’s name, buyer assumption with a new guaranty, or a price adjustment reflecting the added risk.
The practical step is to address these protections in the LOI rather than waiting for the purchase agreement. Lease assignment failure is one of the top reasons dental deals collapse after a purchase agreement is executed, and the seller often has the most leverage to request protections while competition among buyers still exists, before exclusivity is granted to a single buyer.
Protecting Price And Achieving A Clean Exit
Dental practice sale lease issues create a valuation challenge as well as a legal one. The seller who audits the lease before listing and requests protections in the LOI can protect both price and the likelihood of a clean exit. Every clause discussed in this article can have a dollar consequence. A short remaining term can shrink the buyer pool, an unreleased guaranty can follow the seller into retirement, and a stalled landlord can collapse a deal that took months to assemble.

Frequently Asked Questions
Can a Landlord Block the Sale of My Dental Practice?
A landlord can delay or complicate a dental practice sale if the lease requires consent to assignment and grants the landlord broad discretion to withhold it. Whether a landlord can block the sale depends on the consent standard in the lease and the governing state law. Some states imply a reasonableness requirement even when the lease is silent, while others allow a landlord to refuse without explanation if the lease contains no limiting language. Dental practice sale lease issues related to landlord consent are best addressed before listing, when the seller still has leverage to negotiate the consent standard and build protections into the LOI.
What Happens to My Personal Guaranty When I Sell My Practice?
Assigning the office lease to a buyer does not automatically release the seller from a personal guaranty because the landlord’s consent to the assignment is not, by itself, a release. Without an express written release from the landlord, the selling dentist can remain personally liable for the buyer’s rent, additional charges, and even the landlord’s legal fees through the remaining lease term. Sellers can negotiate a release, a burn-off provision, or a new lease in the buyer’s name, and benefit from raising this issue in the LOI rather than waiting until closing.
How Many Years Should Be Left on the Lease for a Buyer to Get Financing?
For SBA 7(a) loans, which are the most common financing vehicle for dental practice acquisitions, the combined remaining firm term plus buyer-exercisable renewal options generally must equal or exceed the loan term, which is typically 10 years for a goodwill-heavy acquisition without real estate. Renewal options count toward this requirement only if they transfer to the buyer, because options personal to the seller do not satisfy the lender. Conventional dental practice lenders typically require at least 5 to 7 years of combined term. Sellers should confirm the specific calculation with the buyer’s lender in writing, because requirements can vary by lender and loan structure.
Should the Buyer Assume My Lease or Sign a New One?
Assuming the existing lease often works better for the seller because it preserves the existing rent, term, and renewal options and avoids giving the landlord an opportunity to reset rent to current market rates or impose new guaranty terms. A new lease may be the better path when the existing lease has very little remaining term, unfavorable escalation clauses, or no renewal options, provided the buyer has time and leverage to negotiate favorable terms. The choice between assignment and a new lease is best evaluated as part of the pre-listing lease audit rather than left to the buyer’s attorney at closing.
Do Change-of-Control Clauses Matter If I Sell to a DSO?
Change-of-control clauses can be especially significant in DSO and private-equity transactions. Many commercial leases define a change in the controlling ownership of the tenant entity as an assignment requiring landlord consent, even when the practice stays in the same location. In a DSO deal, the entity holding or benefiting from the lease may change hands as part of the transaction structure, which can trigger the clause even when the parties assume the lease is undisturbed. Sellers benefit from identifying change-of-control language during the pre-listing audit and negotiating a consent or waiver path with the landlord before signing an LOI with a corporate buyer.
