Rental Review: How to Determine Fair Market Rent

Setting or reviewing rental income is not something you should guess. If the rent is too high, vacancy risk increases. If it is too low, income is lost over time. In both cases, poor decisions compound financially. A structured rental review ensures that the income generated by a property aligns with current market conditions.

Rental markets shift based on supply, demand, location and economic factors. What was considered market rent twelve months ago may now be outdated. This is why periodic review is essential, particularly for investment properties and commercial leases.

Engaging a professional rental review ensures that rental levels are supported by real market evidence rather than assumptions.

What Is a Rental Review?

A rental review is the process of assessing the current market rent of a property. It determines whether the existing rent reflects what tenants are willing to pay under current conditions.

This applies to both residential and commercial properties, although the approach may differ depending on lease structures and market dynamics.

Why Rental Reviews Are Important

Failing to review rent regularly leads to misaligned income. In a rising market, landlords may be undercharging. In a declining market, overpriced rent can lead to extended vacancies.

Rental reviews are essential for:

  • Ensuring rental income reflects current market conditions
  • Supporting lease renewals and negotiations
  • Maximising return on investment
  • Reducing vacancy risk
  • Maintaining competitive positioning in the market

Without a proper review, rental decisions are based on outdated or incomplete information.

The Rental Review Process

A professional rental review follows a structured approach to ensure accuracy.

Market Analysis

Comparable rental properties are analysed to determine current market rates. This includes similar properties in the same location with comparable features.

Property Assessment

The property is evaluated based on condition, size, layout and overall appeal. These factors influence tenant demand and achievable rent.

Adjustment

Rental data is adjusted to account for differences between properties, ensuring a realistic estimate.

Conclusion

A recommended rental range is provided based on market evidence and property characteristics.

Factors That Influence Rental Value

Rental value is determined by multiple factors that must be considered together.

  • Location and proximity to amenities
  • Property size and layout
  • Condition and presentation
  • Market demand and vacancy rates
  • Economic conditions and interest rates
  • Local competition and available supply

Ignoring these factors leads to inaccurate rental pricing.

Residential vs Commercial Rental Reviews

Residential rental reviews typically focus on comparable listings and tenant demand. Leases are usually shorter, and rent adjustments are more frequent.

Commercial rental reviews are more complex. They often involve lease clauses, fixed increases, market reviews and considerations such as tenant covenant strength and property income performance.

Because of this, commercial rental reviews require more detailed analysis and professional input.

Benefits of Professional Rental Review

Using a structured, professional approach provides clear advantages.

  • Accurate market-based rental assessment
  • Improved income optimisation
  • Reduced vacancy risk
  • Stronger negotiation position
  • Better long-term investment performance

This ensures that rental decisions are based on evidence rather than guesswork.

When to Conduct a Rental Review

Rental reviews should be carried out regularly to keep income aligned with the market.

  • At lease renewal
  • During rent review clauses in commercial leases
  • After significant market changes
  • When vacancy occurs

Waiting too long to review rent often results in lost income or extended vacancy periods.

Conclusion

A rental review is a critical part of managing property income effectively. Without it, landlords risk underperformance or unnecessary vacancy.

By analysing market data and property-specific factors, a professional rental review provides a clear and defensible rental figure. This ensures that income decisions are based on current market conditions, not outdated assumptions.
