HKD; monthly averages rounded to the nearest cent. Occupancy cost includes the fees entered, but excludes refundable deposits.
Method and a worked example
Effective monthly rent = rent after concessions ÷ full term months
Illustrative example, not an advertised offer: HK$8,000 a month, a 24-month term and 3 rent-free months gives HK$168,000 of rent over the term and HK$7,000 average monthly rent, before other fees.
What the model includes
A flat monthly rent, whole rent-free months and an unconditional one-off rent discount. Add monthly non-rent charges and non-refundable setup fees separately to compare occupancy cost.
Scope and limits
This simple model does not time cash receipts, include refundable deposits, prorate partial months, model stepped rents or verify conditional incentives. Fees are assumed payable for every term month, including rent-free months. Confirm the actual signed terms.
