Which tool should I start with?
If you are still comparing properties, start with Real Deal Price so you know whether two offers are genuinely comparable. Once a unit is selected, move to Total Purchase Cost. Add the Instalment Planner early for off-plan property because payment timing can matter as much as the headline total.
What should I use if I only have the listing price?
Begin with Real Deal Price rather than treating the advertisement as your final purchase figure. Then use Total Purchase Cost and add the transaction items you can verify. If a cost is still unknown, keep it visible as an unknown instead of filling the gap with a convenient market average.
How accurate are the calculators?
They are only as accurate as the inputs. A calculator cannot automatically know the rate your bank will apply, a unit-specific contractual charge or the final official registration calculation. Treat the result as a planning and comparison tool, then confirm the live figures before payment.
Which tools matter most for an off-plan purchase?
The core chain is Real Deal Price, Total Purchase Cost and the Instalment Planner. Together they show what the purchase costs and when the money must be available. Use Off-plan or Ready Property earlier if you have not yet decided whether construction-stage risk fits your timing and priorities.
Which tool should I use for an investment property?
Do not start with the advertised yield. First establish a credible entry price and total cash cost, then use Rental Break-even to test the operating assumptions. If the model only works with near-perfect occupancy or an unusually high rent, the assumptions deserve another pass.
Why use a currency converter if my bank will give me the actual rate?
The converter is for planning before the transfer. It lets you see how a different exchange rate changes the purchase budget in the currency you actually hold. Your bank still controls the live rate, spread, fees and payment route, so its quote is the number to confirm before sending funds.
How are these tools different from guides on taxes, prices or yield?
A guide explains the subject; a tool works with the facts and assumptions of your property. This parent page deliberately does not rewrite Thailand's tax, pricing or return guides. Use the specialist guide to understand the topic, then come back to the relevant tool to test your own deal.
Do I need to use all seven tools for every purchase?
No. A home bought for personal use may not need rental break-even, while a cash purchase has no reason to use an instalment planner. The point of this hub is to route you to the checks that match the stage and type of transaction you actually have.
