Rent Review Clauses That Actually Protect Your Bottom Line

You know what's more expensive than a bad tenant?

A bad rent review clause.

Too many landlords sign leases thinking rent reviews are standard.

Spoiler: they’re not.

If your rent review clause isn’t strategically structured with ratchet and collar protections, you’re exposed.

We’re talking thousands in potential losses - every year.

Done right, a rent review ensures your income grows predictably, stays fair, and protects your asset's value even during a downturn.

Done wrong? It hands power to the tenant, invites disputes and slowly erodes your returns.

What Is a Rent Review?

A rent review is a clause in your commercial lease that determines how and when rent is adjusted - usually annually or at set intervals. It’s often tied to:

  • CPI (Consumer Price Index)
  • Market rent
  • Fixed annual increases

or a combination of all three.

But here’s the thing most landlords and sadly, many property managers miss:

The real power of a rent review isn’t in the review itself - it’s in the limits you place around it.

Enter: Collar Clauses and Ratchet Clauses.

Collar Clauses: The Rental Safety Net Most Leases Are Missing

A collar clause sets a floor and a ceiling for rent changes during a review.

It protects:

  1. Landlords from rent crashing in soft markets
  2. Tenants from price shocks in high-inflation periods

✅ Example (CPI-linked with collar):

CPI = -1% → Rent holds at 2% minimum

CPI = +8% → Rent capped at 5%

This stops your rent from swinging like a yo-yo when the economy moves.

Types of Collar Clauses:

  1. Fixed % Collar: Rent adjusts between two fixed points (e.g. 2%-5%)
  2. CPI-Linked Collar: Tied to inflation, but capped top and bottom
  3. Market Rent Collar: Applies a ceiling/floor even during market reviews
  4. Hybrid Collars: Mix CPI, market and fixed with tailored caps

Smart? Absolutely. Used by most landlords? Nope.

We make sure it’s baked into every lease we manage and structured right.

Ratchet Clauses: The Most Underrated Weapon in Lease Protection

Let’s say the market takes a hit. Without a ratchet clause, your tenant could renegotiate your rent down.

Now you’re losing income, dropping yield, and hurting the valuation of your property.

A ratchet clause stops that by ensuring rent can’t go backwards or only so far.

Types of Ratchet Clauses:

1.  Hard Ratchet

Rent never goes down. Period.

✅ Strong for landlords

❌ Not enforceable in retail leases in QLD & NSW

❌ Can scare off quality tenants

2.  Soft Ratchet

Rent can drop but only to a minimum (usually the original lease rent).

✅ Fair

✅ Often Retail Act compliant

✅ Retains income stability

3.  CPI Ratchet

Rent can only go up or stay flat, based on CPI.

✅ Great for long-term leases

✅ Less tenant pushback

✅ Predictable

If your lease is in QLD or NSW and includes a hard ratchet for a retail property, you might be relying on a clause that’s not even legal.

That’s not a minor oversight - that’s income at risk.

Soft Ratchet Clauses: The Middle Ground That Works

If you’re trying to balance fairness with financial protection, soft ratchets are your best friend.

They let the rent adjust with the market but not fall through the floor.

5 Smart Ways to Use a Soft Ratchet Clause:

  1. Market Rent Review with a Soft FloorRent can't fall below the original rent
  2. CPI - Linked ReviewRent never drops below a base, even if CPI is negative
  3. Hybrid Review with Fallback IncreasesIf market suggests a drop, fall back to a fixed increase
  4. "No More Than X% Drop" RuleRent can decrease, but only to a capped % (e.g. max 10%)
  5. Sector - Specific AdjustmentsCustom soft floors for seasonal or turnover-based leases

Bottom line? These clauses protect income, tenants and keep your lease compliant.

No Clause = No Protection

If your lease doesn’t have a collar or ratchet clause or worse, has one that’s illegal, unclear, or badly structured - you’re exposed. Full stop.

  • Rent could drop 15% in a downturn
  • Tenants could walk during renegotiation
  • Your property valuation could sink with your rental yield

And here's the worst part:

Most people in the industry, leasing agents and property managers too, don’t check these clauses until it’s too late.

We do it up front. Every lease, every review, every client.

Rent Review Strategy That Works

A powerful rent review clause is about more than indexing rent. It’s about protecting long-term yield, staying legally compliant, and building trust between landlords and tenants.

Whether you own a portfolio or a single site, your lease should be a tool for growth - not a gamble.
