A practical valuation guide for medical property owners in the Greater Phoenix Arizona region
A Phoenix medical office building is worth what a qualified buyer can support based on its income, leases, physical condition, and realistic alternatives for the space. A reliable estimate starts with the property’s actual records and relevant closed sales, then considers how value changes if tenants leave, expenses rise, or leasing takes longer. A citywide price per square foot alone cannot answer those questions.
For an occupied investment property, the starting point is usually sustainable net operating income and the risk attached to it. For a vacant building or an owner-user acquisition, functional suitability, comparable sales, and the cost of achieving occupancy can matter more. Establishing a well-supported range is recommended before deciding whether to sell, refinance, renew leases, or pursue a sale-leaseback.
Define the Property Interest and the Valuation Date
An estimate should state what is being valued and when. A leased building is sold subject to its existing leases. A physician-owned property offered with a new leaseback creates a different income stream. A vacant building available for immediate occupancy competes for another buyer pool. The medical practice, equipment, and real estate also need to be separated; a sale price that includes operating assets is not automatically a real estate comparable.
Ask for today’s value in the property’s current condition, along with any separately labeled stabilized scenario. Stabilized value assumes a specified level of occupancy and income. Reaching that position may require downtime, tenant improvements, leasing commissions, and capital work. Those costs, along with the time and risk involved, should be considered before treating the future scenario as an indication of current value. The OCC’s lending handbook describes income, sales comparison, and cost approaches, and the appropriate approach depends on the property and the purpose of the analysis.1
Build an Income Figure a Buyer Can Verify
Net operating income, or NOI, is property operating revenue less property operating expenses under a stated convention, generally measured before financing costs, income taxes, and depreciation. Capital projects, tenant improvements, and leasing commissions must also be modeled, even when presented below NOI. Lenders and market participants may treat replacement reserves differently, so the NOI used in a comparison must be consistent.1
Reconcile the trailing 12 months of operations with the rent roll, executed leases, amendments, and actual collections, then compare those results with the next 12 months. Explain contractual increases, free rent, vacancies, bad debt, expense reimbursements, and unusual repairs. A signed lease is not the same as rent already being collected, and a tenant’s reimbursement obligation is not proof that every expense is recoverable.
A meaningful reconciliation also recognizes expenses an owner has absorbed informally. Management, repairs, and recurring building services do not disappear because the current owner performs them. Equally, an isolated capital replacement should not be treated as an ordinary annual expense without explanation. Each adjustment should have a clear reason and supporting information, since overly optimistic add-backs can overstate sustainable income.
Understand How the Cap Rate Changes the Answer
Direct capitalization divides annual stabilized NOI by a market-supported capitalization rate to indicate value, and works best when the income stream is reasonably stable. A discounted cash flow model is more useful when material lease expirations, lease-up, changing expenses, or major capital work make the timing of cash flows important. Neither method removes the need for market evidence.1
A cap rate reflects more than the property’s address. Remaining firm lease term, rent relative to market, the actual tenant and guarantor, termination rights, capital obligations, and future leasing prospects all affect the income’s risk. A health-system name on the sign does not establish a parent guaranty — the executed documents and the party legally responsible for payment should be reviewed directly.
Hypothetical Value Sensitivity
The following example uses an assumed $700,000 of annual stabilized NOI. The cap rates shown are for illustration only and are not intended to represent current Phoenix market guidance or the value of any particular property.
| Assumed Cap Rate | Illustrative Value | Calculation |
|---|---|---|
| 6.5% | $10.77 million | $700,000 ÷ 0.065 |
| 7.0% | $10.00 million | $700,000 ÷ 0.070 |
| 7.5% | $9.33 million | $700,000 ÷ 0.075 |
Illustrative only — not current Phoenix market guidance or the value of any particular property. Based on an assumed $700,000 of annual stabilized NOI.
At the illustrative 7.0% rate, a recurring $35,000 reduction in NOI reduces the indicated value by $500,000. That explains why an expense-recovery gap or an unsupported rent assumption deserves attention before a property is marketed. A one-time $35,000 repair has a different effect, since its amount and timing should be considered rather than treating it as a permanent annual loss — the same issue should not be counted twice, in both cash flow and as a separate deduction.
Choose Comparable Sales That Answer the Same Question
Relevant comparisons share the characteristics that most directly influence the property’s value: location, size, age, condition, tenancy, lease duration, rental basis, parking, medical buildout, and the purchaser’s intended use. Confirm that the reported price is for the real estate being compared, and investigate portfolio allocations, unusual financing, related-party transactions, or distressed circumstances.
Price per square foot is a useful cross-check once those differences are understood. A fully leased surgery center and a vacant medical shell may have similar areas and very different economics. Asking prices show seller expectations; closed transactions provide a stronger starting point for understanding what buyers have actually paid, subject to verification and appropriate adjustments. The OCC’s appraisal-review framework asks whether the selected comparable properties and their adjustments support the conclusion.1
Read Phoenix Market Data in Context
Kidder Mathews’ Phoenix medical office update for Q2 2026 reported 15.1% direct vacancy and an average direct rental rate of $34.39 per square foot on a full-service basis.2 Those figures describe a market sample and period — they do not establish the rent, vacancy allowance, or cap rate for any single building. A full-service asking rent should not be compared directly with a triple-net rent without accounting for the expenses each includes.
The same update reported $151.8 million in quarterly sales, with three transactions accounting for approximately 79% of the total.2 That concentration is a reason to inspect the underlying deals before interpreting higher sales volume as a universal increase in building values. The reporting period, property universe, and transaction mix should all be checked before applying a market statistic to one building.
Within Greater Phoenix, it is important to look at a property’s actual competitive set. An owner-user in the West Valley may value available occupancy, access, and a workable layout, while an investor evaluating a Scottsdale or East Valley asset may focus on the rent roll and future rollover. These are questions for the subject’s buyer pool, rather than reasons to assume that one submarket will always command a premium.
Inspect the Building and the Next Use
Review roof and HVAC condition, parking and access, electrical capacity, plumbing, elevators where present, accessibility, and the suitability of the clinical layout. Identify who owns specialized equipment and who pays for its removal or replacement. Existing improvements may be valuable to one specialty and expensive to adapt for another.
For a vacant or partially occupied asset, consider legal use, realistic tenant demand, construction scope, and the time to start collecting rent. Confirm restrictions in zoning, condominium documents, and other recorded agreements with the relevant professionals. A conceptual conversion plan or nearby hospital does not, by itself, establish an approved use or a committed tenant.
Prepare for a Property Pricing Review
- Property address, parcel information, floor plans, building area, and current occupancy.
- A current rent roll and all leases, amendments, guarantees, and notices affecting the tenancy.
- Trailing 12-month operating statements, recent year-end results, collection records, and reimbursement reconciliations.
- Known repairs, capital history, service contracts, property tax bills, insurance, and association charges.
- Your objective, timing, ownership approvals, and any occupancy you intend to retain after a sale.
The resulting broker opinion of value should include an effective date, property interest, range, relevant comparables, income assumptions, and material unresolved items, and should explain what would change the conclusion. A broker opinion of value supports brokerage decision-making; it is not a formal appraisal or a substitute where an appraisal is required.
Frequently Asked Questions
Can I use the county assessor value as my Phoenix medical office building’s sale price?
Use the county assessor value as context, not as a prediction of what a buyer will pay today. Maricopa County describes Full Cash Value as a market-value estimate subject to mass-appraisal conditions for the stated tax year, and Limited Property Value serves a separate tax purpose. Neither figure replaces a property-specific analysis as of your intended transaction date.3
Does a fully occupied medical office building always sell for a higher price?
Occupancy only commands a premium when the leases produce dependable income. Below-market rent, early termination rights, weak payment support, or near-term rollover can reduce that benefit, while vacant possession may be attractive to an owner-user who needs the space. Identifying the likely purchaser gives a more accurate read on value than assuming occupancy is an automatic premium.
Should I renew tenant leases before selling my medical office building?
Consider the renewal economics alongside the likely buyer strategy rather than renewing automatically. A renewal can improve income visibility, but concessions, landlord work, options, or restrictive terms can offset that benefit, so the proposed lease and sale scenarios should be evaluated together before committing.
What is a broker opinion of value and how does it differ from an appraisal?
A broker opinion of value is a pricing analysis that states an effective date, the property interest being valued, a supported value range, relevant comparables, income assumptions, and any material unresolved items. It supports brokerage decision-making, but it is not a formal appraisal and does not substitute for one where an appraisal is required.
How does the capitalization rate affect my Phoenix medical office building’s value?
The capitalization rate converts stabilized net operating income into an indicated value, so small changes in the rate produce large swings in price. For example, $700,000 of annual NOI indicates roughly $10.77 million at a 6.5% cap rate versus $9.33 million at 7.5%, a $1.44 million difference driven entirely by the rate used. The appropriate rate reflects lease term, tenant credit, capital obligations, and leasing risk rather than the property’s address alone.
