What is covenant strength in commercial real estate?

Quick answer

Covenant strength is a tenant's financial ability to pay the rent and meet every other obligation in its lease for the full term: a strong covenant makes the income more secure and the property worth more at a lower yield, while a weak one raises the risk of default. It is assessed from the tenant's accounts, credit ratings or scores, rent cover, and any guarantee or deposit behind the lease. Scayled does not rate covenants. It acts when a lease ends or a covenant fails, finding 250 to 350 businesses the building suits and the person who signs at each.

What does covenant strength mean?

In a lease, covenants are the tenant's promises: to pay rent and service charges, repair, insure where required, and comply with the use and alienation terms. Covenant strength is how likely the tenant is to keep those promises until the lease ends. The term is standard in the UK, Australia and New Zealand; in the US the same idea is usually called tenant credit.

It attaches to the legal entity named on the lease. A lease signed by a small subsidiary of a large group is not a group covenant unless the parent guarantees it, so the first question is always who exactly is liable.

How is covenant strength assessed?

For private companies, start with the filed or audited accounts: profitability over several years, net assets, cash, debt and gearing. Rent cover, usually profit before interest, tax, depreciation and amortisation divided by rent, shows how comfortably the business can carry the lease. Commercial credit scores from Creditsafe, Dun & Bradstreet or Experian add payment behaviour, court judgments and filing history.

For larger companies, credit ratings from S&P, Moody's and Fitch are the reference point. Investment grade means BBB minus or above at S&P and Fitch, Baa3 or above at Moody's. Time trading, sector, and the security on the lease (parent guarantee, rent deposit, bank guarantee or letter of credit) complete the picture.

Why does covenant strength affect property value?

Investors price the income stream, and a stronger covenant with a longer unexpired term makes that stream more certain, so buyers accept a lower yield. As an illustration, a rent of 1,000,000 capitalised at 5 percent is worth 20 million; at 6 percent it is worth about 16.7 million. The same building and the same rent can differ in value by millions on covenant alone.

Lenders apply the same logic. Covenant strength and unexpired term affect how much a lender will advance against an asset and on what terms, which is why weak covenants can make a property harder to refinance as well as to sell.

How do funds keep track of covenant strength after buying?

Most funds put material tenants on a credit monitoring service. Creditsafe, Dun & Bradstreet and Experian send alerts when a score, filing, legal event or director changes; CreditRiskMonitor's FRISK score estimates bankruptcy risk for public companies; and MSCI's Income Analytics service scores tenants to quantify real estate income at risk. Arrears in Yardi or MRI are the earliest hard evidence.

Filed accounts lag. A UK private company has nine months after its year end to file accounts at Companies House, so a monitoring alert can arrive long after the business changed. News on the tenant, conversations with its management and site visits fill that gap.

What can weaken a covenant during a lease?

Covenants change over a lease term. Common causes are an acquisition or refinancing that adds debt, the loss of a key customer or contract, a restructuring that moves the operation to another entity, an assignment of the lease to a weaker company, or a sector downturn.

Lease drafting is the main defence: conditions on assignment, guarantees that survive an assignment (in England and Wales, an authorised guarantee agreement from the outgoing tenant), and rights to request financial information. Once a covenant has weakened, the practical question becomes how quickly the unit could be re-let.

What happens when a covenant fails, and where does Scayled fit?

When a tenant fails, the landlord pursues arrears, draws on any deposit or guarantee, and in most cases ends up with the space back. From then on, every month without a new tenant costs rent plus outgoings. Scayled shortens that stretch by assembling, from a brief on size, use and who the unit should suit, the 250 to 350 businesses most likely to take it. It finds the person who signs at each and writes an approach explaining why the building fits them.

That re-let is sold as The Campaign, one payment per vacancy with no subscription and no commission on the new lease. Most fund units suit the Full campaign, US$749 for 250 to 350 businesses in about five working days; a Focused list of the strongest 100 to 150 starts from US$449. A failed covenant often hands the unit back with little notice, which is when finding a tenant for a vacant industrial unit quickly matters most.
