Two properties with the same asking rent can leave their owners with very different income. This worksheet separates full-year rent from vacancy and operating costs. It is a comparison tool, not a forecast of Phnom Penh market returns.
Build your own scenario
Enter a purchase price and your estimated costs. Use documented rent evidence for the unit or a genuinely comparable property. The prefilled example is fictional and is not a J-Tower 3 rental projection.
Illustrative example: $12,000 scheduled annual rent; $9,000 net operating income; 6.00% gross yield; 4.29% net operating yield.
What the two percentages mean
Monthly rent × 12 ÷ purchase price × 100.
[Monthly rent × (12 − vacant months) − annual operating costs] ÷ [price + purchase costs + fit-out] × 100.
The net operating result is before financing, personal income tax and resale costs. It does not include future price appreciation. Include owner-paid building fees, management, maintenance, insurance and recurring property charges in operating costs as applicable. Avoid counting the same cost twice.
Stress-test vacancy before you shortlist
| Vacancy | Collected rent | Net operating income | Net operating yield |
|---|---|---|---|
| 0 months | $12,000 | $10,000 | 4.76% |
| 1 month | $11,000 | $9,000 | 4.29% |
| 3 months | $9,000 | $7,000 | 3.33% |
Use evidence that matches the property
Compare buildings, bedrooms, size, condition, furnishings and lease inclusions. An advertised rent is not proof that a tenant agreed to it. Ask for recent signed lease evidence where it can be shared appropriately. Keep projected rent for an unfinished development separate from existing rental records.
Start with sale listings and rental listings, then ask us for a unit-specific comparison. For J-Tower 3 Anna Suite, request the purchase cost and delivery assumptions before modelling future income.
Does the calculator include loan payments?
No. Subtract financing cash flows separately. A property yield and a return on your cash equity are different measures.
What is a good rental yield in Phnom Penh?
There is no universal number that makes a purchase suitable. Compare evidence, vacancy exposure, ongoing costs, liquidity and your own objectives. This page does not claim a citywide benchmark.
