Full Waiting Rooms, Tight Cap Rates
A cardiology practice in Weston signs a new ten-year lease. A dermatology group in Boca Raton outgrows its space and needs 6,000 square feet within eighteen months. An orthopedic surgery center in Aventura wants to be within walking distance of a hospital campus but cannot find a building with the parking ratio or backup power its equipment requires. These are not hypothetical scenarios. They are the conversations playing out across South Florida’s medical office market right now, and they explain why cap rates on well-leased medical buildings in the region have compressed to a range most commercial investors have not seen in years.
Medical office buildings, often shortened to MOBs in commercial real estate circles, occupy a different category than the office towers and strip retail most investors think of first. Occupancy nationally is running near its highest level in more than a decade, and new construction has slowed even as demand from healthcare providers keeps climbing. For an investor who understands the asset class, that combination, tight supply and durable tenant demand, is the setup worth paying attention to.
This guide covers how medical office real estate works as an investment, why Florida’s demographics make it a market to watch, which South Florida submarkets are seeing the most activity, and what a serious buyer checks before signing a contract.
Why Florida’s Demographics Are Reshaping Healthcare Real Estate
Florida’s population skews older than almost every other state in the country. More than one in five Florida residents is age 65 or older, according to U.S. Census Bureau data on the aging population, and South Florida counties consistently rank among the highest concentrations of older residents nationwide. That population does not shrink its use of healthcare services as it ages. It grows.
Two forces are stacking on top of each other. First, tens of thousands of retirees relocate to Florida every year, many of them from Northeast and Midwest states with higher taxes, and they bring their healthcare needs with them. Second, the healthcare industry itself has been shifting procedures out of hospitals and into outpatient settings for years, a trend regulators have accelerated by expanding the list of procedures Medicare will cover outside a hospital stay. Cardiac catheterization, joint replacement, and a growing list of surgical procedures that once required an inpatient stay now happen in outpatient surgery centers, many of them housed in medical office buildings.
For an investor, that means demand for medical office space is not tied to a single economic cycle the way retail or hotel demand can be. It is tied to a demographic curve that is not reversing anytime soon, and to a regulatory trend that keeps pushing more procedures into exactly the kind of building this asset class provides.
What Makes a Medical Office Building Different
A medical office building looks like standard commercial space from the parking lot, but the inside tells a different story. Physician tenants build out plumbing for exam rooms, dedicated electrical circuits for imaging equipment, lead-lined walls for radiology, and backup generator capacity that a law firm or insurance office never needs. That buildout is expensive, often $75 to $150 per square foot depending on the specialty, and it is a major reason medical tenants sign longer leases and renew at higher rates than typical office tenants. A practice that just spent seven figures fitting out an ambulatory surgery center is not moving buildings every five years.
Lease structure matters as much as the tenant. Most medical office leases in Florida are triple net, meaning the tenant pays a proportional share of property taxes, insurance, and common area maintenance on top of base rent. That shifts most operating expense risk off the owner’s balance sheet, which is part of why medical office has become a favored asset class for investors coming out of 1031 exchanges who want predictable income without hands-on management.
Tenant credit quality varies widely and should never be assumed. A building leased to a hospital system or a large multi-specialty group carries different risk than one leased to a solo practitioner. Before underwriting a purchase, an investor should know exactly who is on the lease, how long the practice has operated, and whether the tenant’s revenue depends on a single insurance contract or referral relationship that could change.
South Florida Submarkets Investors Are Watching
Medical office demand is not uniform across South Florida. Certain corridors have pulled ahead because of hospital proximity, population density, and physician group concentration.
Broward County’s Weston Corridor
Weston and the surrounding western Broward corridor have become one of the most active medical office markets in South Florida, driven by proximity to Cleveland Clinic Florida’s Weston campus and a dense concentration of specialty practices. Well-leased buildings in this corridor have traded at cap rates roughly between 5.75 percent and 7 percent, depending on tenant credit and remaining lease term, tighter than general commercial office pricing in the same county. Investors researching specific parcels can pull ownership, assessed value, and sales history directly through the Broward County Property Appraiser.
Palm Beach and Miami-Dade Corridors
Palm Beach County’s medical office activity clusters around the West Palm Beach and Boca Raton hospital corridors, where an aging, affluent resident base supports specialty practices in cardiology, orthopedics, and dermatology. In Miami-Dade, Aventura and Kendall have both seen new medical office development tied to hospital campus expansions. Across all three counties, buildings within a short drive of a hospital or major health system campus consistently command tighter cap rates and faster lease-up than standalone buildings without that proximity.
- Weston (Broward): specialty-heavy, strong hospital anchor, most competitive pricing
- Boca Raton and West Palm Beach (Palm Beach County): dense senior population, high specialty demand
- Aventura and Kendall (Miami-Dade): growth tied to hospital campus expansion
None of this means every medical office building in these corridors is a sound purchase. Location narrows the field. Underwriting decides whether a specific building belongs in a portfolio.
Underwriting a Medical Office Acquisition
Cap rate alone tells an investor almost nothing without context. A 6.5 percent cap rate on a building leased to a hospital system with twelve years remaining on the lease is a fundamentally different risk than the same cap rate on a building leased to three solo practitioners with three years left, no renewal options exercised, and below-market rent that will jump sharply at renewal.
A disciplined underwriting process works through several layers. Start with the rent roll and read every lease, not a summary. Confirm whether expenses are truly triple net or whether the landlord retains responsibility for roof, structure, or HVAC replacement, which can be a meaningful capital obligation on a building with aging mechanical systems. Check the parking ratio against the tenant mix. Medical tenants generally require more parking per square foot than office tenants because patients arrive and leave throughout the day rather than commuting once. A building with 4 spaces per 1,000 square feet may work for a law firm and fail a physician group’s requirements entirely.
Hurricane resilience deserves its own line item in South Florida. Backup generator capacity, impact windows, and flood elevation all affect a medical tenant’s ability to keep operating after a storm, which affects lease renewal risk and insurance cost. A building that lost power for a week after a hurricane and could not run refrigeration for vaccines or medications is a building physicians remember when their lease comes up for renewal.
Financing and Tax Structuring
Medical office real estate is a common landing spot for investors completing a 1031 exchange out of another commercial property, because the durable lease income and lower management burden fit well with an investor rotating out of an asset that required more active involvement. The exchange mechanics themselves do not differ from any other commercial 1031, but the compressed timeline, 45 days to identify a replacement property and 180 days to close, means investors should have a target submarket and a relationship with a broker who tracks medical office inventory before the exchange clock starts.
Depreciation is where medical office ownership gets more technical than a typical office purchase. The extensive tenant improvements inside these buildings, plumbing, specialized electrical, imaging shielding, often qualify for shorter depreciation schedules than the building shell itself under a cost segregation study, which can meaningfully accelerate deductions in the early years of ownership. The framework for how commercial property owners depreciate real and personal property components is laid out in IRS Publication 946, How to Depreciate Property, and any cost segregation study should be prepared by a qualified engineer or CPA familiar with the standard, not estimated informally.
Financing a medical office purchase in Florida also carries the state’s documentary stamp tax on the note and, in most counties, an intangible tax on the mortgage, both due at closing and calculated off the loan amount. Current rates and calculation methods are published by the Florida Department of Revenue, and they should be built into a deal’s closing cost estimate from the first offer, not discovered at the closing table.
Due Diligence Before You Buy
Older medical office inventory faces a real obsolescence problem. Buildings constructed in the 1990s and early 2000s were not designed around today’s parking ratios, imaging equipment power loads, or patient flow expectations, and retrofitting them can cost more than the difference in purchase price versus newer stock. Walk the building with a contractor before closing, not just a property inspector, and ask specifically whether the electrical service and structural floor loading can support a future tenant’s imaging or surgical equipment.
Confirm zoning and any local approvals tied to the specific medical use in place. An urgent care clinic, an ambulatory surgery center, and a general practitioner’s office can carry different local permitting requirements, and a change in tenant type at renewal could require new approvals the current use never needed. Review title and survey the way any commercial purchase requires, and verify the seller’s disclosed rent roll against actual lease documents and tenant estoppel certificates before the contingency period closes.
- Full lease abstract review, not a rent roll summary
- Parking ratio and patient flow fit for current and likely future tenants
- Generator, flood elevation, and hurricane resilience specific to the building
- Cost segregation feasibility reviewed with a qualified professional before closing
- Zoning and use approvals confirmed for the specific medical use, current and anticipated
None of this diligence is optional simply because the tenant wears a white coat instead of a suit. Medical office is a specialized asset class, and it rewards buyers who treat it that way.
Working With a Team That Understands Both Sides
Medical office real estate sits at an intersection most brokerages are not built to serve well. It requires the underwriting discipline of a commercial team and, often, a buyer who is simultaneously searching for a personal residence in the same South Florida market. At MJI Realty Group, we work with investors moving between both worlds, a physician group partner buying a building for their practice while also relocating a family to Palm Beach or Broward County, or a commercial investor building a healthcare real estate portfolio alongside a primary residence purchase. Our market expertise across residential and commercial transactions sets us apart, and we bring the same discretion to a nine-figure commercial acquisition that we bring to a waterfront estate sale.
If you are evaluating a medical office acquisition in South Florida, or weighing how it fits alongside other commercial holdings, MJI Realty Group can walk through the submarket data and underwriting with you before you make an offer. Real estate investment decisions depend on individual financial circumstances, tax position, and risk tolerance; this article is general information, not legal, tax, or investment advice for your specific situation, and any cost segregation study, 1031 exchange, or financing structure should be reviewed with a qualified CPA or attorney before you commit capital.
