Why Low REIT Vacancy Can Still Mean Weak Rental Cash Flow
Distinguish area-based and property-count vacancy measures from actual rent collection. Examine rent-free periods, lease expirations, tenant concentration, and interest costs to assess rental income stability.
Low vacancy indicates that space is occupied, but does not guarantee that all rent is received in cash. Check how occupancy is measured, rent-free periods, arrears, and lease expirations, then examine how operating and financing costs reduce rental income.
Align the vacancy denominator with the share of rent at risk
REITs may report occupancy based on floor area, property count, or other measures. Realty Income's annual report describes occupancy by property count, which cannot be compared directly with area-based vacancy in large offices. Several vacant small properties and the loss of one high-rent tenant have different cash effects even if the property count is the same. Look at the rent previously generated by vacant space and its re-leasing prospects alongside vacant area. Also check whether assets under construction and assets held for sale are included in the calculation.
The difference between contractual rent and cash receipts
Attracting new tenants may involve rent-free periods or fit-out contributions. Even a high headline contractual rent can produce lower effective cash returns after these incentives. Rental income recognized on a straight-line basis over the lease term can also differ from cash received in the current period, so read accounting policies and relevant adjustments. Responsibility for service charges, repairs, taxes, and insurance varies by lease structure. When comparing property operating income metrics, failing to align included costs can produce different profitability judgments even with the same rent growth.
Put concentrated lease expirations and refinancing on the same calendar
Even high current occupancy may come with different renewal bargaining power if many leases expire the following year. Check tenant credit quality and industry and regional concentration, and read rent-free periods and capital expenditure alongside rent increases on renewal. If debt maturities overlap with lease expirations, vacancies and rising interest costs can pressure cash simultaneously. Supplementary measures such as FFO and AFFO for US REITs also use company-specific adjustments, so do not treat them as identical to net income or cash available for distribution. Follow the connection between cash flow and dividend funding through each REIT's disclosures.
Worked example
Hypothetical example: If 9,000 m² out of 10,000 m² of leasable area is under lease, area-based occupancy is 90%. At monthly rent of KRW 20,000 per m² of leased space, nominal monthly rent is KRW 180 million. If 1,000 m² of that space is in a rent-free period, simple cash receipts are KRW 160 million. This calculation excludes arrears, service charges, and accounting straight-lining. Occupancy of 90% does not mean a cash rent collection rate of 90%.
What to check
- Have you checked whether occupancy is based on area or property count?
- Have you accounted for rent-free periods and tenant incentives?
- Have you examined major tenants' lease expirations and credit quality?
- Have you connected debt maturities and interest costs with rental cash flow?
