Key takeaways
- Review the signed lease, amendments and notices together; a rent summary is not the complete agreement.
- Separate the right to take over the premises from any release of the seller’s ongoing obligations.
- Use the buyer’s full occupancy cost in the earnings model, including later rent changes and assigned expenses.
- Coordinate landlord contact with the seller’s confidentiality plan and the deal’s actual deadlines.
Why does the lease belong near the start of diligence?
The value of an operating practice depends in part on where care takes place. Patients know the address. The equipment, utilities and room layout support the current services. If the buyer cannot secure workable rights to stay, the purchase model needs a different plan. A lower price alone does not create a usable location.
The ADA's sale-preparation resource identifies the lease as a matter to address before a sale. Its buyer guidance also calls attention to lease terms and renewal options. These are reasons to review the documents early, not promises that the landlord must accept a buyer.

Treat this guide as a commercial review worksheet. Your attorney must interpret the actual documents and applicable law. Legal requirements vary by place, agreement and deal structure. No national consent rule or required lease term is asserted here. The review framework was checked in September 2026.
Which documents should the seller provide?
Request the complete signed lease and each amendment. Ask for renewal notices, assignments, consents and any side agreements that affect occupancy. Confirm the current tenant's legal name and the premises covered. An agreement for extra storage or parking may sit outside the main office lease.
Ask whether there are unresolved notices, rent disputes or promised repairs. A current rent bill can help check the amounts being charged, but it does not replace the contract. Where documents conflict, identify the conflict for counsel. Do not select the more favorable version and assume it governs.
| Document or evidence | Question it helps resolve | Review owner |
|---|---|---|
| Signed lease and amendments | What rights and duties currently exist? | Buyer’s attorney |
| Renewal and option notices | Were relevant deadlines met? | Attorney with seller’s records |
| Rent bills and annual reconciliations | What has the tenant actually paid? | Buyer’s CPA and attorney |
| Consent and assignment history | Were earlier transfers documented? | Attorney |
| Repair records and inspections | What work may be needed after purchase? | Qualified property and equipment reviewers |
| Lender lease conditions | What evidence is required for funding? | Lender and attorney |
| Proposed assignment or new lease | What will change for the buyer? | Buyer’s attorney |
Maintain a missing-document list with a responsible person and response date. An unanswered request should remain visible in the diligence log. If the closing plan relies on a right that no one can document, the team needs to resolve that gap before treating it as available.
Is the buyer taking an assignment or signing a new lease?
An assignment transfers specified lease rights and obligations under the governing documents. A new lease creates a new agreement. The economic result may differ even when the buyer occupies the same rooms. Ask counsel to explain which path is being proposed and what approvals it requires.
Do not assume that an entity purchase avoids review. A change-of-control clause may address ownership changes even when the named tenant remains. Counsel should compare the transaction structure with the lease language. The asset versus stock sale guide explains why the legal form affects several diligence workstreams.
Separate three questions: can the buyer take over, what must the buyer agree to, and is the seller released? Consent to a transfer does not by itself answer every question about past or future obligations. Ask for a clear summary of what the signed documents would leave with each party.
How do remaining term and renewal options affect the plan?
List the current end date and each stated option period. Then ask who may exercise the options, what notice is required and how rent is set. A potential renewal is not the same as a fully reviewed right to renew. Conditions and missed deadlines may matter.
Ask the lender to state its own lease requirements in writing. Do not rely on a general claim that every practice loan needs the same number of years. The relevant question is whether the proposed rights meet the requirements of this financing and support the buyer's operating plan.
The AAE hosts a practice-planning guide revised in May 2014 that includes lease review topics. It is useful as a historical question list. Its examples and sample provisions are not a substitute for current advice or terms to copy into your agreement. (Source: AAE-hosted PBS Endo practice guide (revised May 2014), revised May 2014; retrieved September 2026.)
For your own decision, compare the period of secure occupancy with planned spending. Major new equipment or room work may take time to justify economically. If the location could be lost before that plan is practical, show the exposure in the decision model instead of assuming that an extension will be granted.
What is the full cost of staying in the premises?
Base rent is only one input. Read the agreement for additional charges, utilities, insurance, repairs and other assigned costs. A lease may describe common-area maintenance, often shortened to CAM. Ask what enters that charge, how it is allocated and whether estimates are reconciled later.
Build the cost schedule from documents, current bills and qualified estimates. Show what is known, what is estimated and what remains open. Avoid filling an unknown repair cost with zero. A zero is a financial assumption that can make the purchase look more affordable than the evidence supports.
The next table is an invented annual cost example. It is not local rent data, a typical dental lease, or a recommendation about cost levels. Both columns exclude loan payments and use the stated monthly amounts for a full year.
| Illustrative occupancy item | Seller’s current monthly cost | Buyer’s proposed monthly cost |
|---|---|---|
| Base rent | $3,300 | $4,200 |
| Additional premises charges | $600 | $750 |
| Utilities and premises insurance in this example | $400 | $500 |
| Budgeted repairs in this example | $200 | $450 |
| Total monthly occupancy budget | $4,500 | $5,900 |
| Total annual occupancy budget | $54,000 | $70,800 |
The modeled increase is $16,800 a year. If all other revenue and expenses stay the same, that amount reduces available earnings before financing and taxes. It is larger than the base-rent increase alone. Make sure the model removes the seller's old cost before adding the buyer's new cost; adding the entire new budget twice would overstate the expense.
How should step-ups, deposits and repairs enter the model?
A rent step-up is a scheduled change in rent. Show it in the period when it takes effect rather than spreading the first month's rent across the whole forecast. If rent depends on a later calculation, record the formula and test a reasonable range with the CPA. Do not label a chosen scenario as a forecast from the landlord.
A deposit can require cash at closing without being the same as a recurring rent expense. Ask the CPA how to classify it and the attorney whether it is transferred, replaced or returned to the seller. Fees, prepaid rent and repair reserves also need distinct treatment. The sources-and-uses schedule should show the cash needed to complete the deal.
For an invented timing example, suppose a buyer must place a $10,000 new deposit and fund $15,000 of immediate repairs. That creates $25,000 of cash needs under the stated assumptions. It does not mean annual occupancy expense rises by $25,000. The accounting treatment and timing need separate review.
If the seller owns the building, use the actual lease proposed for the buyer. Related-party rent in past accounts may not match it. Do not carry a low historical rent into the acquisition model simply because it improved the seller's reported earnings. Value the business and any real estate transaction with consistent assumptions.
Which operating rights should the buyer investigate?
Ask whether the permitted use fits the planned services. Check access hours, signage, parking, utilities and the ability to maintain or replace installed equipment. Ask qualified reviewers about the physical premises and applicable approvals. A history of dental use does not by itself answer every question about a buyer's proposed changes.
Read the repair and alteration provisions with the operating plan beside them. If the buyer intends to add rooms, move equipment or change utility demands, identify whose approval is needed. Establish who owns improvements and what may have to be removed when occupancy ends. These are questions for the documents and advisors, not assumptions to infer from a walkthrough.
Review any rights concerning relocation, demolition, damage, interruption or early termination. The point is to understand what could interrupt the business and what response the agreement provides. Ask counsel to explain consequential terms in plain language before deciding whether the remaining risk is acceptable.
How do guarantees affect the buyer and seller?
A guarantee is a separate promise to answer for specified obligations. Read who gives it, what it covers, when it ends and whether proposed changes affect it. Do not assume that forming an entity resolves every personal obligation created by a signed guarantee.
For the seller, ask what remains after the transfer and what evidence would establish a release. For the buyer, ask whether a new guarantee has a limit or conditions and how it relates to other deal obligations. Counsel should assess the actual wording. The broker can keep the issue on the closing list but cannot create a release through a commercial summary.
Use a clear issue entry such as “seller release unresolved; attorney reviewing proposed consent.” That is more useful than “lease okay.” The latter hides which parts have been reviewed and which still require a decision.
When should the landlord and lender be involved?
Agree with the seller on who will contact the landlord and what can be disclosed. A consent request can reveal the proposed sale. Coordinate it with the confidential sale process, while allowing time to obtain the rights on which closing depends.
Ask for the landlord's document requirements and expected review steps. Avoid promising a response date that the landlord has not accepted. Give the lender the same current lease package the attorney is reviewing. A loan model based on old rent and a contract based on new rent can create a late financing problem.
Bank of America describes financing for dental practice needs including acquisitions and commercial real estate. Program availability does not establish approval for this purchase or acceptance of its lease. Obtain the actual conditions from the lender handling the application.

| Milestone | Evidence to seek | If still unresolved |
|---|---|---|
| Early offer review | Complete lease package and proposed transfer path | Reflect the uncertainty in offer conditions |
| Diligence review | Attorney issues list and buyer occupancy budget | Assign answers and model changes |
| Funding preparation | Lender’s written lease-related conditions | Coordinate needed documents and timing |
| Closing preparation | Required executed consent, lease or other evidence | Follow counsel’s advice on unmet conditions |
| Operating handover | Keys, access, contacts and service arrangements | Assign responsibility for continuity |
Tie deadlines to the signed purchase documents. If an extension or other change is needed, ask counsel to document it. A casual email that everyone is “working on the lease” should not be treated as proof that contractual dates changed.
Common mistakes in a dental practice lease review
Do not treat a verbal willingness to consider assignment as executed consent. Do not count an option period without reviewing its conditions. Do not assume a stock sale removes a consent issue or that a consent automatically releases the seller. Each shortcut skips a separate question.
Do not compare rent alone while omitting repairs and additional charges. Do not assume all patients would follow a move to a cheaper office. If relocation is a serious alternative, price the work, downtime and operating changes as a separate plan. The choice needs more than a comparison of monthly rent.
Finally, do not let the lease review become an isolated legal exercise. Feed changed costs into the financial model and changed rights into the closing plan. The buyer's attorney, CPA and lender should be working from the same proposal.
Summary
A sound lease review connects the documents with the buyer's right to operate and full cost of occupancy. It keeps consent, renewal rights, guarantees and seller release as separate questions. The lender and advisors need the same current terms before closing. Bring the open issues and revised budget to the deal team before relying on the premises in your offer.
Frequently asked questions
Can the seller promise that the landlord will approve assignment?
A seller’s promise is not a substitute for the rights and required approvals under the lease and applicable law. Have counsel confirm the transfer path and the documents needed for this purchase.
Is base rent the complete occupancy cost?
Not necessarily. Additional charges, utilities, insurance, repairs and other assigned duties may affect cost. Use the proposed agreement and supporting bills to build the buyer’s complete budget.
Does a stock sale avoid lease consent?
Do not assume it does. Change-of-control language may matter even if the named tenant stays the same. Ask counsel to review the actual structure and lease together.
Does an assignment release the seller from the lease?
Treat release as a separate question. The effect depends on the agreements and applicable law. Ask counsel what obligations remain and what signed evidence would establish the intended release.
How many lease years does a dental lender require?
Obtain the requirements for your specific financing. This guide does not state a universal term. Ask how the lender treats options, conditions, assignments and proposed changes.
What if the seller also owns the building?
Review the lease proposed for you or the separate property purchase terms. Use a consistent rent assumption when valuing practice earnings. Past related-party rent may differ from your future cost.
Should a security deposit be treated as annual rent?
Keep the cash requirement separate from recurring occupancy expense. The CPA should determine accounting treatment, and counsel should confirm who holds the deposit and what happens to it at transfer.
What if the location cannot be secured on workable terms?
Evaluate a documented extension, new lease, property purchase or relocation plan where available. Each has different costs and risks. Ask counsel about the purchase agreement before pausing, changing or ending the transaction.
