What it earns, what it costs to own, and the net yield

Financial analysis
· Brixfox Standard · Non-resident · Fully managed
Fully managed is the Brixfox Standard shown on every card: a full-service manager's commission, charged on top of the Airbnb/Booking channel fees (not the cleaning cost — changeovers are funded by guest cleaning fees; you bear the residual). Self-managed drops the commission; the channel fees stay, because the platform is paid whoever manages, and you pay staff/local operations, a higher cleaning residual and your own time directly. Both scenarios divide the SAME gross revenue — the toggle changes the cost stack, not the revenue. That revenue is observed from actively-operated comps, so self-managed assumes you match their performance.Both scenarios share the same projected revenue — the toggle changes who runs the property and what that costs, not what it earns.
Net yieldNet operating income ÷ all-in investment. After local operating taxes; before home-country personal tax and financing costs. Modelled from observed market performance of comparable Airbnb listings.

Income tax is Thai personal income tax on 70% of gross rent (the standard 30% deduction), at the 0–35% rates and before any personal allowance. The 15% a Thai payer withholds from a non-resident's rent is credited against this on the tax return, so it is not an extra cost. Financing is not modelled.

Rental yield + value growth

Your net rental yield plus a yearly rise in the property's market value (land and building) that you choose. Value growth is an assumption, not data — which is why it starts at 0% and is kept out of the yield figures above.
