Medical Office DST 1031 Properties
Medical office is one of the most recession-resistant categories of commercial real estate. Healthcare demand grows with the population, doesn't move online, and rarely contracts during downturns. Medical office DSTs hold buildings leased to physician groups, health systems, and outpatient providers under long-term agreements. This page covers how medical office DSTs work, why investors choose them, and what a typical medical office DST 1031 offering looks like.
What Is a Medical Office DST 1031?
A medical office DST 1031 is a Delaware statutory trust that holds one or more medical office buildings (often abbreviated MOBs) leased to healthcare tenants. Per Revenue Ruling 2004-86, beneficial interests in the trust are treated by the IRS as direct interests in real estate, which is what allows them to qualify as 1031 replacement property.
Medical office breaks down into two main categories. “On-campus” buildings sit on or adjacent to a hospital campus and are typically leased to physician groups affiliated with the hospital. “Off-campus” buildings are freestanding outpatient facilities in retail or suburban locations, often anchored by a major health system or a multi-specialty physician practice. Both qualify for DST treatment, but they have different demand drivers and lease structures.
Most medical office DSTs are structured as long-term leases to creditworthy tenants. Hospital systems, large physician groups, and national outpatient operators sign 10 to 15 year leases on these properties. Tenant stickiness is a defining feature: specialized build-outs (imaging equipment, surgical suites, lab plumbing) make relocation expensive and disruptive.
Why Investors Choose Medical Office for a DST 1031
Medical office is often described as the most defensive category of commercial real estate. Four reasons it shows up regularly in DST 1031 allocations, particularly for investors prioritizing income stability over growth.
Recession-resistant tenant demand
Healthcare spending grows steadily through economic cycles. People don’t postpone necessary medical care when the economy weakens, and an aging population is driving sustained increases in outpatient visit volumes. That stability flows through to medical office occupancy, which historically holds in the low to mid 90s through recessions when office and retail soften.
Sticky tenants with high relocation costs
Medical practices invest heavily in their space. Imaging equipment, surgical suites, lab plumbing, specialized HVAC, and the patient base built around a specific location all make relocation expensive and disruptive. As a result, medical office tenants renew at higher rates than tenants in conventional office or retail. That stickiness translates into predictable income for the DST.
Long lease terms with built-in escalators
Medical office leases typically run 10 to 15 years at signing, often with multiple 5-year renewal options. Most include scheduled rent escalators (fixed annual increases or CPI-linked bumps). The combination gives medical office DSTs a long-dated, contractually growing income stream.
Demographic tailwind
The U.S. population over age 65 is growing significantly faster than the broader population. Older patients use roughly three times the healthcare services of younger patients. That demographic shift is creating sustained demand for outpatient facilities, particularly in growing metros. The tailwind isn’t speculative. It’s a function of population data already in place.
What a Typical Medical Office DST 1031 Looks Like
| Property type | On-campus medical office building (adjacent to a hospital) or off-campus outpatient facility. Single-tenant or multi-tenant medical. |
|---|---|
| Building size | 30,000 to 150,000 square feet typical. Larger campuses or medical office portfolios exist. |
| Tenants | Hospital systems, large physician practice groups, ambulatory surgery centers, urgent care operators, imaging providers, and specialty clinics. |
| Geography | Sun Belt metros and growing suburban markets are most common. Demand follows population growth and aging demographics. |
| Lease term | 10 to 15 years initial term, often with multiple 5-year renewal options. Triple-net or modified-net structure with built-in rent escalators. |
| Typical hold period | 5 to 10 years. |
| Debt structure | Non-recourse senior debt at the trust level. Loan-to-value generally 50% to 60%. |
| Cash flow | Monthly distributions paid from net rent. Projected, not guaranteed. |
| Minimum investment | Around $100,000 for 1031 exchange investors. |
| Exit | Sale of the underlying property. Investors receive their share of net proceeds and may 1031 exchange again. |
Risks Specific to Medical Office DST 1031s
Every DST investment carries the general risks of illiquidity, sponsor dependency, and loss of principal. Those are covered in detail on the main risks page. Medical office adds a few asset-class-specific risks worth understanding.
Tenant credit varies widely
Medical office tenant credit ranges from large investment-grade health systems to small independent physician practices. A 5-doctor specialty group does not carry the same financial profile as a national hospital chain. Tenant financial review is essential on every medical office DST, particularly for properties leased to smaller practice groups.
Healthcare reimbursement and regulatory change
Medical office tenants depend on revenue from insurance reimbursement, Medicare, Medicaid, and direct patient payment. Changes to reimbursement rates, regulatory requirements, or healthcare policy can affect tenant profitability and ability to pay rent. The risk is rarely catastrophic, but it’s a unique exposure that doesn’t exist in other asset classes.
Specialized space limits backup tenant options
The same specialized build-outs that make medical tenants sticky also make spaces harder to re-tenant. A surgical suite or imaging center can’t easily convert to general office space without significant capital. If a medical tenant does leave at lease end without renewing, finding a replacement medical user typically takes longer than re-leasing a comparable conventional office property.
These are medical office specific considerations. See our main risks page for the full picture of DST 1031 risks.
How Medical Office Fits in a Multi-DST Allocation
For exchanges over roughly $500,000 in equity, our advisors often recommend splitting the proceeds across two or three DSTs rather than placing everything in one. Medical office is most commonly used as the income-stability leg in those allocations, paired with growth-oriented asset classes.
A common pairing is multifamily plus medical office. Multifamily provides diversification across many tenants and inflation-responsive income. Medical office provides long-duration leases to creditworthy healthcare tenants whose demand doesn’t move with the broader economy. The two combine into a portfolio that captures rent growth in good years and holds income in weak ones.
Investors prioritizing income stability above all else sometimes pair medical office with net-lease retail or industrial. All three share the long-lease, single-tenant or low-tenant-count profile, but they spread risk across different tenant industries: healthcare, consumer retail, and supply chain. Our advisors walk through which combinations match an investor’s debt requirement, income needs, and risk tolerance during the consultation.
