Who actually signs the lease

Many vet buildings on the market are leased to national practice groups, and the listing tells you so in large type. What it often doesn't tell you is which company actually signed the lease.

That one fact decides what the rent is worth. A lease signed by a group's parent company is backed by hundreds of clinics, while one signed by a company set up to run a single clinic is backed by that clinic alone.

This fall we read twelve sale packages for vet buildings front to back, looking for that answer, and six of them never gave it.

What we looked at

The twelve packages were offering memoranda for single-tenant vet buildings on the market in 2026, leased to ten different practice groups. Brokers send these to buyers who sign a confidentiality agreement, and they're usually the first detailed look anyone gets at a deal.

For each one we wrote down four things: what the tenant field said, what the lease signature line said if there was one, whether a guarantor was named, and how the narrative pages described the tenant. We didn't have the leases themselves. The point was to see what a buyer can learn from the marketing before asking for documents.

What we found

Every package put the group's brand in the tenant field, which on its own doesn't say who signed.

Six of the twelve had no signature line at all. Of the six that did, three named the parent or main operating company, two named a company created to hold a single clinic's lease, and one gave only the brand name, for a lease that starts at closing.

Guaranties were even thinner. One package named a guarantor. Another had a line for the guarantor and filled it with the word "Corporate," which isn't a company. The other ten didn't mention one.

The narrative pages didn't help. In both cases where a one-clinic company signed, the write-up still called the tenant by the national group's name, three times each. One brand profile gave two different location counts on the same page. Another listed a well-known investment firm behind the group, a firm with no connection to the lease.

Why it matters

The company that signs the lease is who owes the rent. If it stops paying, the landlord can go after that company and anyone who guaranteed the lease, and nobody else. A group with hundreds of clinics doesn't help you much if one of its single-clinic companies is the tenant and that clinic closes.

Lenders look at it the same way. A weak signer usually means more questions, a smaller loan or both, and whoever buys the building carries that into the price they're willing to pay.

If you own a building that's already leased, the signer was settled the day the lease was signed, and a careful buyer will find it whether or not the listing says. If you're about to sign a lease, whether after selling your practice to a group or in a sale-leaseback, this is the moment it gets decided. Ask for the parent company to sign, or to guarantee the lease. Groups often push back, but before the lease is signed is when you have the most leverage to ask, and a parent signature or guaranty makes the building easier to finance and sell.

How to check a lease yourself

You don't need a lawyer for a first look. Five things, in this order:

1. Go to the signature page. The company named above the signature is the tenant, whatever the cover page or the marketing says.
2. Read the company's name closely. A town or street in the name, like "Group of Springfield, LLC," usually means a company that exists to hold one clinic.
3. Look the company up in the state's business registry. You'll see when it was formed, where it's registered and whether it's in good standing.
4. Look for a guaranty. It's normally a separate document. Note who signed it, whether it's capped, and whether it falls away after a set number of years.
5. Read the assignment clause. Some leases let the tenant assign the lease to an affiliate and be released from it, which can turn a strong signer into a weak one later on.

If you're selling, do this before a buyer does. If you're buying, ask for the signed lease and any guaranty before you spend money on anything else.

Notes on method

We read twelve offering memoranda for single-tenant veterinary buildings on the market in 2026, covering ten practice groups. Several came from one brokerage's set and used the same template. For each we recorded the tenant field, the lease signature field, any guarantor field and the narrative description of the tenant. A company was classed as single-clinic when its name tied it to one location and nothing in the package said otherwise.

A few caveats. We read marketing packages, not the executed leases or guaranties, so a guaranty could exist that the package didn't mention. Twelve is a small set, and one brokerage's template shaped several of them. We have named no groups, buildings or brokers here.
