Where Should Your Next Practice Go?

Before you tour a single suite we map the trade area around every location you are considering: who lives there, how fast it is growing, what they can pay, and how many providers in your specialty already sit inside a realistic drive time. It costs nothing and you keep the analysis whether or not you ever hire us.

What This Costs Your Practice

Nothing Out Of Pocket, In Almost Every Case

The landlord is already paying a leasing fee.

It is written into the listing agreement before you ever walk in. In a typical lease that fee is split between the broker representing the building and the broker representing the tenant.

If you negotiate alone, the other side keeps all of it.

You do not save that money by going without representation. It simply stays with the broker sitting across the table from you, whose job is the landlord's outcome, not yours.

Hiring us moves that money to your side.

Our share comes out of the fee the landlord was already going to pay. For most practices that means no separate fee out of pocket, and no invoice from us.

A handful of situations work differently: space offered directly by an owner, physician-owned buildings, sublease space, and some institutional landlords may offer a reduced fee to a tenant's broker or none at all. We confirm the arrangement in writing on every building before you tour it, and if one is an exception you hear it from us first. Brokerage fees are not set by law and are fully negotiable.

Practice counts are our own tally of distinct practice addresses drawn from public federal registries for San Antonio and South Texas, current September 2026.

What We Actually Calculate

Saturation, Then The Gaps

Most site advice stops at population and median income. Those two numbers tell you a place has people with money in it, which is true of almost every corridor anyone would consider. They do not tell you whether those people already have a dentist, an orthopedist, or a veterinarian, which is the part that decides whether a new office fills its schedule.

Saturation

Providers in your specialty per ten thousand residents inside a real drive time, measured against the same ratio for the metro and for comparable corridors. A corridor is not saturated because the traffic feels heavy. It is saturated when that ratio sits well above what the population underneath it supports.

Gap analysis

The inverse question, and the more useful one. Where do population, growth and payer mix support more of your specialty than are currently there? Those are the corridors where a new office opens into demand rather than into a fight with three incumbents.

Drive time, not circles

A three-mile radius drawn on a map crosses 1604, Loop 410 and the Medical Center's parking, and pretends none of that slows a patient down. We use drive times at the hours your patients actually travel, which routinely reshapes a trade area past recognition.

Referral geography

For a specialist the question is not rooftops. It is which primary care practices and which hospitals feed you, where they sit, and how far a referring physician will realistically send someone. A specialist can be right about the demographics and still land on the wrong side of the referral map.

Cannibalization

For a second or third location, how much of the new trade area your existing office already serves. Adding a site that quietly eats your own patients is the most expensive way there is to grow, and it is invisible until the second year.

What is actually leasable there

A corridor that scores beautifully and has nothing available in your size range is not an answer. Every recommendation gets checked against the space that actually exists, including suites that have not been marketed yet and sublease space that is not on any listing site.

Where The Numbers Come From

Every Source, Named

You should be able to ask where any figure came from and get an answer. Here is the whole list.

  • NPPES, the federal provider registry. Every enumerated provider and organization in the country, with a practice address and a taxonomy code. This is how we count competitors by actual specialty instead of by business name.
  • CMS clinician and enrollment files. Who is genuinely billing from an address, which is how a registry entry that has gone stale gets caught.
  • CLIA laboratory registrations. Finds operating practices that never surface in a physician list at all.
  • Census and the American Community Survey. Population, growth, age distribution, household income, and health insurance coverage, at the block-group level rather than the ZIP code.
  • County appraisal and deed records. Who owns the building, what it last traded for, and whether your prospective landlord is a competing physician group.
  • Our own medical office building dataset. 1,300+ buildings across San Antonio and South Texas, which is what lets us say whether a quoted rate is reasonable for that building type in that corridor.
  • Calling and driving. We verify the short list ourselves. Data gets you to five corridors. It does not get you to the right suite.

The Honest Part

What This Analysis Cannot Tell You

Anyone who hands you a single location score with no sources behind it is selling you confidence rather than analysis. Here is what the data genuinely cannot see, so you know which part of the answer is measured and which part is reported.

  • Whether a competitor's panel is already full, or closed to new patients. Two practices at the same address can be in completely different positions.
  • Whether a physician two blocks away is retiring in eighteen months, which can change a corridor more than any demographic trend will.
  • Whether a group has already signed a lease on a building that has not opened yet. Nothing public shows that. It comes from knowing the brokers who did the deal.
  • How good a competitor actually is. Providers per capita counts doors, not quality, and a well-run practice in a crowded corridor still beats a poor one in an empty corridor.
  • Registry lag. An address stays in the federal data after a practice has closed or moved, so a raw count is always slightly stale. We verify before we count, and we tell you what we could not verify.

Where we cannot answer something from data, we write it down as a question rather than filling the gap with a guess. That list of open questions is usually the most useful page in the report.

What You Get

A Written Brief, Not A Dashboard

  • A trade-area map for every location under consideration, built on drive times rather than circles.
  • Population, growth, median age, household income and insurance coverage inside each one.
  • Every competing practice in your specialty inside that area, by name and address, so you can check the list against what you already know.
  • Providers per capita against a metro benchmark, so you can see at a glance whether the corridor is thin or crowded for your specialty.
  • A ranked short list of corridors, and the space actually available in each with a realistic view of what it will cost to occupy, not just the asking rate.
  • The questions we could not answer from data, written out as questions.

Turnaround depends on the scope. A look at one corridor is quick. A metro-wide search for a specialty with a long referral tail takes longer. Tell us the deadline and we will tell you honestly whether we can meet it.

By Corridor

Start With The Market You Are Considering

Each of these is a real submarket with its own rents, parking, landlords and build-out realities. The analysis goes deeper than these pages, but they are a fair place to start.

South Texas Medical Center

The densest concentration of medical real estate in South Texas, and the hardest submarket to lease well. Here is what actually drives a deal on this campus.

The Medical Center ›

Stone Oak and US 281 North

Where San Antonio's elective and cash-pay specialties look first, and where the hardest thing to find is a small second-generation suite.

Stone Oak ›

Westover Hills and Highway 151

The clearest cause and effect story in San Antonio medical real estate: beds left the Medical Center and reappeared out here.

Westover Hills ›

The South Side and the University Health Palo Alto campus

A half million people, one hospital, and a new 166-bed campus landing in 2027. The timing question here is real and it is not far away.

The South Side ›

Northwest 1604, Huebner and La Cantera

For physicians who want Medical Center referral proximity without Medical Center rent, parking or campus politics.

Northwest 1604 ›

Alamo Ranch and far west San Antonio

Rooftops well ahead of medical supply, three freestanding emergency rooms, and no hospital. The absence is the whole story.

Alamo Ranch ›

Downtown San Antonio

The only San Antonio submarket where a practice bids against law firms for the same floor plate, and where parking cost decides the deal.

Downtown ›

Alamo Heights, Broadway and North Central

Where cash-pay and referral-light practices go: older buildings, small suites, surface parking that works, and the good space never hits the market.

North Central ›

The I-35 northeast corridor

Two systems adding inpatient capacity on the same eight miles of I-35, and about 100,000 square feet of attached medical office that has to be leased.

The I-35 northeast corridor ›

New Braunfels and Comal County

Two competing hospital systems in one of the fastest growing counties in the country, and a leasing market tight enough that waiting has a real cost.

New Braunfels ›

Boerne and Kendall County

A county that has never had a hospital is getting one, with medical office attached. The pre-leasing window is open right now.

Boerne ›

Common Questions

Demographics and competition analysis

How do you decide whether an area is saturated?

We count the providers in your specialty inside a realistic drive time, using the federal provider registry rather than a business directory, and divide by the population actually inside that drive time. Then we compare that ratio against the metro as a whole and against corridors with similar demographics. A single number means nothing on its own. The comparison is the whole point, and we show you the comparison set rather than just the verdict.

Is the analysis really free?

Yes, and you keep it whether or not you hire us. We do this work before an engagement because it is how we earn one, and because a practice that opens in the wrong corridor is not a client we keep. If you take the report and use another broker, that is a fair outcome and it happens. When you do hire us, the landlord typically pays the leasing fee and our side is paid from it, so most practices never write us a check at all. We confirm that arrangement in writing on every building before you tour it.

I already have an address in mind. Can you just tell me if it is good?

Yes, and that is the fastest version of this. We will run the trade area around that address, show you the competing practices inside it, and tell you where it sits against the alternatives you have not looked at. Sometimes the answer is that the address is right and you should go. Sometimes it is that a corridor four minutes away has half the competition for the same rent.

How is this different from the demographic report a listing broker gave me?

The person who gave it to you is paid by the landlord of the building it recommends. That does not make the numbers wrong, but it does decide which numbers appear and which corridors are missing from the comparison. We do not take a fee from any building in the analysis, so the comparison set includes the buildings that are bad for us and good for you.

Do you do this outside San Antonio?

Yes. The federal and census data is national, so the method travels. San Antonio and South Texas is where we also know the buildings, the landlords and the brokers personally. Elsewhere in Texas and across the Southeast we run it with Partners Healthcare Services, and in a market where none of us sit we bring in the best local broker to check the ground truth.

Will you tell me not to open?

If that is what the numbers say, yes. We have more to gain from being right than from one lease. Telling a practice that a corridor will not carry a second location, or that renewing where they are beats every alternative, is a normal outcome of this work.

Part Of A National Healthcare Practice

Partners Healthcare Services

In July 2026 Partners Real Estate acquired Crown Tenant Advisors, an Atlanta-based firm specializing in tenant and buyer representation for healthcare practices, and launched Partners Healthcare Services, serving clients in the medical, dental, and veterinary sectors. Crown was founded in 2009 by Andrew Riepe and built its practice on the tenant and buyer side rather than taking landlord listings. We are the San Antonio and South Texas arm of the practice.

That matters when your practice grows past one market. Partners was founded in 1997 and reports more than 300 professionals, with offices in San Antonio, Austin, Houston, Dallas-Fort Worth, and Atlanta. The healthcare practice has people on the ground in Georgia, North Carolina, South Carolina, Indiana, and Florida, and Partners is expanding across the Carolinas, Nashville, and the Florida markets.

And where we do not have an office, we do not hand you to a junior broker in a branch. We bring in the best broker in that market, whatever firm they work for, and run the assignment with them. One relationship covers your second location, whether it is across 1604 or across the country.
