Installment Leverage and 5-Year Returns: How Real Is 30% ROI on Cambodia Property?

TL;DR: The advertised "30% ROI" on Cambodian real estate is a cash-on-cash return on the invested portion under an interest-free installment plan — not the asset's own yield. Net rental income delivers ~8% per year. With full equity financing over 5 years, a realistic return is 9–13% annually, depending on price appreciation assumptions.

Why "30% ROI" and "8% Rental Yield" Describe the Same Property

Seeing both figures in one pitch deck isn't a mistake — they measure entirely different things.

Asset yield = net rental income ÷ full purchase price. For a TS5 1BR unit at $72,000: $5,677 / $72,000 ≈ 7.9% per year.

Cash-on-cash return = the same income ÷ actual cash invested. Under an interest-free developer installment plan (typically 30/40/30 over 36–54 months), a buyer may have deployed only $36,000 at the time of calculation, while price appreciation accrues on the full $72,000. This is financial leverage — the same mechanism as margin investing, with the developer acting as the lender.

Breakdown with $36,000 deployed and 10%/year price growth:

Component Calculation Cash-on-Cash
Net rental income $5,677 / $36,000 15.8%
Price appreciation $7,200 / $36,000 +20.0%
Total — ≈ 35.8%

At 5%/year growth the total drops to ~25.8%. The leverage ratio doesn't change — only the price growth assumption does.

Four Conditions That Must Hold for 30%+ to Be Real

The figure is mathematically correct only when all of the following are true simultaneously:

  • The installment plan is genuinely interest-free. Verify in the contract — "0%" financing is sometimes offset by an inflated presale price.
  • Price appreciation actually materialised. This is a forecast, not a fact. BKK1 (Phnom Penh) carries documented oversupply risk.
  • The second tranche has not yet been paid. Once you've paid in full, your cash-on-cash converges with the asset yield.
  • Exit taxes and sales commissions are excluded. CGT (~4% effective after 2027) + sales commission (~4%) together consume up to 8% of the exit price.

The property itself generates ~8% from rent. Everything above that is leverage and a price appreciation assumption.

5-Year Total Return: Full Equity Scenarios

Purchase in 2026, sale approximately in 2031. Full equity financing of $72,000.

Net rental income over 5 years: ~$5,677 × 5 = $28,385 (no rent escalation, conservative; 85% occupancy, 10% management fee).

Metric Conservative (5%/yr growth) Optimistic (10%/yr growth)
Asset value in 5 years $91,900 $115,950
Price appreciation +$19,900 +$43,950
Net rental income (5 yrs) +$28,385 +$28,385
Sales commission (~4%) −$3,676 −$4,638
CGT ~4% eff. (post-2027) −$3,676 −$4,638
Total profit ≈ $40,900 ≈ $63,100
Return on $72k ~57% / ~9.4%/yr ~88% / ~13.4%/yr

Key note: Exit before 01 January 2027 means CGT = 0 (Prakas 346), adding $3,700–4,600 to net profit and meaningfully improving IRR.

With a 50% installment structure, the annualised cash-on-cash return rises to 18–27%/year — but downside risk scales proportionally: a price decline also doubles the loss on invested capital.

Key Risks in the BKK1 Market

Any investment model is a set of assumptions, not a promise. For BKK1 condos, the following risks are material:

Oversupply. BKK1 is one of the most supply-saturated districts in Phnom Penh for new condo projects. This suppresses rental rates and complicates resale at projected prices.

Zero or negative price growth. If prices stagnate, the leveraged return drops to ~15–16% (rental only). If prices fall, losses on the leveraged position double.

CGT from 2027. Capital gains tax (20%; effectively ~4% of asset value after standard deductions under Prakas 346) applies to disposals after 01 January 2027.

Vacancy. The model assumes 85% occupancy. At 70% occupancy, net income drops by roughly 18%, materially affecting total return.

Exit costs. Sales commission (~4%) plus legal costs must be modelled upfront; they are often omitted from advertised ROI figures.

How to Read Advertised ROI Figures as a Foreign Buyer

When evaluating any Cambodia real estate offer, ask three questions:

  1. Is ROI calculated on invested capital or on asset value? If on invested capital — clarify the down payment size and installment terms.
  2. What price growth rate is assumed? 10%/year is aggressive for the current Cambodian market. Ask for a zero-growth scenario.
  3. Are CGT and sales commissions included? A model that omits these overstates the outcome by 6–8% of asset value.

A credible developer or agent will present all three scenarios (pessimistic, base, optimistic) with full disclosure of assumptions. Absence of this transparency is a red flag.

FAQ

Q: What is the difference between cash-on-cash ROI and asset yield for Cambodia real estate? A: Asset yield is net rental income divided by the full purchase price — for a $72,000 unit with $5,677 annual net rent, that's ~7.9%. Cash-on-cash ROI divides the same income by actual cash invested. Under a 50% installment plan, cash-on-cash is roughly double the asset yield, which explains the gap between "8%" and "30%" in the same pitch.

Q: When does Cambodia's capital gains tax (CGT) take effect, and what is the rate? A: CGT at 20% has been deferred to 01 January 2027 under Prakas 346. Transactions closed before that date are exempt. After 2027, the effective tax burden is approximately 4% of the asset's sale value after standard deductions. For a sale in 2031, CGT would reduce total profit by roughly $3,700–4,600 depending on the exit price.

Q: Is 9–13% annual return realistic for a condo in Phnom Penh over 5 years? A: Yes — with full equity financing and moderate price appreciation (5–10%/year), the 5-year model produces 9–13% annualised returns after all costs. This requires occupancy above 80% and positive price movement. In a flat-price scenario, the return drops to approximately 6–7%/year (rental only, net of costs).

Q: What does BKK1 oversupply risk mean for an investor? A: BKK1 has seen a significant increase in new condo supply over the past several years. Excess inventory tends to suppress rental rates (lower occupancy, lower achievable rents) and make resale more competitive, potentially limiting or reversing the price appreciation that the optimistic ROI scenario depends on. Conservative underwriting should assume 0–5% annual price growth rather than 10%.
