Renting keeps you flexible and free of Thailand’s hefty property transaction taxes; buying builds equity and captures any appreciation. This calculator nets out both paths over your chosen horizon — including the transfer fee, holding costs, and the opportunity cost of your deposit — and tells you which is cheaper.
How it works
Both paths are projected year by year and compared on net cost:
BUY:
upfront = deposit + transferFee(2%) + buying costs
mortgage P&I = standard amortising payment over term
holding = annual fees, tax, maintenance (% of value)
end equity = future value − remaining loan − selling SBT/stamp duty
net cost = total cash out − end equity
RENT:
rent grows each year by rent inflation
invest the would-be deposit at investment return
net cost = total rent paid − investment growth on deposit
The decisive levers are appreciation (which builds buy-side equity) and the investment return on your deposit (which rewards renting). Because Thailand layers a 2 percent transfer fee and possible 3.3 percent SBT on a sale within five years, short horizons are penalised on the buy side.
Example and tips
For a 4,000,000 baht condo with a 10 percent deposit at 6 percent over a 10-year horizon, renting an equivalent unit at 18,000 baht/month, buying tends to win only if appreciation comfortably exceeds the investment return you could get on the deposit. Run the numbers twice — once with optimistic appreciation, once near zero — and notice how far apart the answers swing. If you might leave Thailand within a few years, the transaction taxes almost always make renting cheaper.
