Koh Phangan property returns — FAQ
Every listing passes our Listing-Vetting due diligence before we publish it. See what we check →- What return can I expect from a Koh Phangan property?
- It depends on the price you pay, how long you hold, and whether you rent it out — so this calculator lets you set your own growth outlook and horizon instead of quoting a single number. The capital-growth presets are anchored to market data, and you can adjust every input.
- How is the projection calculated?
- Projected value compounds your annual growth rate over the holding period. ROI is total profit divided by the cash you invested; CAGR is that return annualised. In rental mode it adds net rental income; for leasehold it reflects the value falling as the lease runs down. Entry, exit and holding costs are included.
- Does it handle off-plan and leasehold?
- Yes. Switch to Full mode: off-plan models the construction payment plan and handover, and leasehold reflects the lease shortening over time. Freehold resale is the default.
- Can I model buying several units or plots?
- Yes. On a project or a land collection, tick the units or plots you would buy and the calculator combines their cost and projection. Percentage returns (ROI, CAGR) are per unit and do not change with quantity.
- Are these numbers guaranteed?
- No — every figure is illustrative and follows your assumptions. We list only personally vetted properties and show honest numbers, but markets vary. Use it to compare scenarios, then talk to us before you decide.
Figures and projections shown here are illustrative estimates based on public and our own market data, for general information only. They are not financial, investment, legal or tax advice, not an offer, and not a guarantee of any return. Property values and rental income can fall as well as rise.
