NAV in a REIT (Net Asset Value): How to Read a Singapore REIT’s Book Value Per Unit
Net Asset Value (NAV) in a REIT is the total value of a REIT’s properties and other assets, minus its liabilities (debt and other obligations), divided by the number of units outstanding — expressed as NAV per unit. It represents the theoretical ‘book value’ of one REIT unit if all assets were sold and liabilities settled.

Key Takeaways
- NAV per unit = (Total Assets − Total Liabilities) ÷ Units Outstanding, revealing the underlying value backing each REIT unit you own.
- REITs trading below their NAV per unit (a ‘discount to NAV’) may be undervalued by the market relative to their property portfolio’s assessed value — or reflect genuine risk concerns.
- REITs trading above NAV (‘premium to NAV’) suggest the market expects future growth, quality, or scarcity value beyond current book value.
- NAV is updated based on periodic independent property valuations, typically at least once a year, not continuously like share prices.
- The Price-to-NAV (P/NAV) ratio, calculated as unit price divided by NAV per unit, is the standard metric investors use to compare REITs.
What Is NAV in a REIT (Net Asset Value)?
Every S-REIT publishes its NAV per unit in quarterly and annual financial statements, based on independent valuations of its property portfolio (conducted by licensed valuers, typically annually) alongside its outstanding borrowings and other liabilities. NAV differs fundamentally from a REIT’s unit price, which is set by market supply and demand on the Singapore Exchange (SGX) and can diverge significantly from NAV depending on investor sentiment, interest rate expectations, sector outlook, and REIT-specific factors like gearing or DPU growth trajectory.
How Does NAV in a REIT (Net Asset Value) Work in Singapore?
To calculate NAV per unit: sum the fair value of all investment properties plus cash and other assets, subtract total borrowings and other liabilities, then divide by total units in issue. For example, a REIT with S$8 billion in property assets, S$500 million in other assets, S$3.2 billion in total liabilities, and 4 billion units outstanding would have a NAV of (8,000M + 500M − 3,200M) ÷ 4,000M = S$1.325 per unit. If the REIT trades at S$1.10 on SGX, it is trading at roughly a 17% discount to NAV; if it trades at S$1.50, it is trading at a roughly 13% premium.
NAV in a REIT Example
CapitaLand Ascendas REIT reports a NAV per unit of approximately S$2.10 in its latest financial statements. If the REIT’s unit price on SGX is trading at S$2.45, it is trading at roughly a 17% premium to NAV, reflecting market confidence in its industrial and logistics portfolio’s growth prospects. By contrast, if a hospitality or office REIT with NAV of S$1.20 per unit trades at S$0.95, that roughly 21% discount to NAV might signal market concerns about sector headwinds, gearing levels, or DPU sustainability — worth investigating further, not automatically assuming it’s a ‘bargain’.
Advantages of NAV in a REIT (Net Asset Value)
- Provides an asset-backed valuation anchor — unlike pure earnings multiples, NAV ties a REIT’s valuation to tangible, independently assessed property values.
- Useful for identifying potential mispricing — a persistent, unexplained deep discount to NAV can flag value opportunities (or hidden risk) worth researching.
- Standardised across the S-REIT sector — all SGX-listed REITs must disclose NAV per unit, enabling like-for-like comparison.
- Complements yield-based analysis — combining P/NAV with distribution yield gives a fuller valuation picture than yield alone.
Risks and Limitations
- Valuations are periodic, not real-time — NAV reflects the last independent valuation date, which can lag fast-moving property market conditions.
- A discount to NAV isn’t automatically a buy signal — REITs can trade below NAV for structurally justified reasons (weak sector outlook, high gearing, asset quality concerns).
- Valuer assumptions vary — cap rates and valuation methodologies differ by asset class and valuer, making cross-REIT NAV comparisons imperfect.
- NAV doesn’t capture income quality — two REITs with identical NAV per unit can have very different distribution sustainability, tenant quality, and lease structures.
NAV vs DPU (Distribution Per Unit)
NAV and DPU answer different investor questions — one is about asset value, the other about income received.
| Aspect | NAV (Net Asset Value) | DPU (Distribution Per Unit) |
|---|---|---|
| What it measures | Underlying asset value per unit | Cash income distributed per unit |
| Update frequency | Typically annually (independent valuation) | Quarterly or semi-annually, per REIT’s distribution policy |
| Used to assess | Whether unit price is over/undervalued vs assets | Income return and distribution sustainability |
| Common ratio derived | Price-to-NAV (P/NAV) | Distribution yield (DPU ÷ unit price) |
| Best used alongside | Gearing ratio, occupancy, WALE | DPU growth trend, payout ratio, tenant concentration |
The Bottom Line
NAV per unit gives Singapore REIT investors an asset-based reference point for whether a unit is trading rich or cheap relative to its underlying property portfolio — but it should always be read together with gearing, DPU trends, and sector outlook rather than used alone to time an entry or exit.
