Amortisation Before Tenant Breaks

Why commercial lenders insist on full repayment ahead of lease events

Overview

When a commercial lender requires a loan to be fully amortised before key tenant breaks or lease expiries, they are not trying to increase yield or restrict the borrower. They are removing refinance and exit risk.

This requirement typically appears on income-producing commercial property where rental security is time-limited, concentrated, or subject to material change. Understanding this lender logic is critical when structuring commercial mortgages for assets with upcoming lease events.

What “full amortisation” actually means

A fully amortising commercial loan is structured so that:

Capital and interest are repaid over the loan term
The loan balance reduces steadily
The loan is fully repaid by maturity, with no reliance on refinance or sale

This contrasts with interest-only lending, where the loan balance remains unchanged and repayment depends on a future exit.

Why tenant breaks change lender behaviour

Commercial lenders underwrite future income certainty, not just today’s rent roll.

Where a property has:

Tenant break options within the loan term
Lease expiries clustered within a short period
Income concentration from a small number of tenants

The lender must assume a downside scenario where income falls materially before loan maturity.

At that point, refinance risk becomes real, so amortisation removes that risk entirely.

The lender’s internal logic

From a credit committee perspective, the question is simple

If the tenant leaves and the value falls, how do we get repaid?

If the answer relies on:

Re-letting risk
Market timing
Yield assumptions
Or borrower support

The lender will typically require structural protection instead.

Full amortisation converts the loan into a self-liquidating facility.

Why lenders prefer structure over pricing

Borrowers often assume lenders will price lease risk through higher interest rates.

In practice, lenders prefer:

Lower leverage
Shorter exposure
Accelerated capital repayment

This is because:

Margin does not reduce loss-given-default
Structure does

Amortisation reduces exposure before lease risk materialises, which pricing alone cannot achieve.

Amortisation vs interest-only: when each applies

Interest-only lending is more likely where:

Income is diversified
Lease lengths exceed loan term
Vacant possession value broadly aligns with market value
Refinance liquidity is strong

Amortisation is typically required where:

Tenant breaks fall within 3–7 years
Income is concentrated
Rent concessions or stepped rents exist
Vacant possession value is materially below market value

In these scenarios, interest-only lending simply defers risk.

Non-recourse lending and amortisation

Where lenders offer non-recourse or limited-recourse structures, amortisation is often non-negotiable.

This is because:

Recovery relies solely on the asset
There is no personal balance sheet support
Capital certainty becomes critical

Amortisation ensures exposure reduces regardless of future leasing outcomes.

Can amortisation be negotiated?

Sometimes — but only within limits.

Potential mitigants include:

Partial amortisation rather than full
Short interest-only periods
Cash sweeps as an alternative
Reduced amortisation after income stabilisation

However, where tenant breaks are the primary concern, full amortisation is often a firm credit requirement.

Why this matters when structuring commercial mortgages

Misunderstanding amortisation requirements is a common reason deals fail late in the process.

Correct structuring means:

Selecting the right lender from the outset
Aligning loan term with lease risk
Avoiding unrealistic interest-only assumptions
Presenting a credible exit strategy

This is a structural decision, not a pricing one.

How Wellspring Capital approaches this

Wellspring Capital structures commercial mortgages around lender credit logic, not headline rates.

Where tenant breaks or lease events drive risk, we advise on:

Whether amortisation is likely
How lenders will assess exposure
Which structures are realistic
When alternative approaches may apply

This avoids late-stage surprises and ensures funding aligns with asset risk.
