Financials

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.

No Airbnb match on file

We have not confirmed this exact property on Airbnb, so it carries no operating history here. The figures above rest on the comparable set — a launch scenario, not a track record.

Revenue assumptions

Derived from the comparable Airbnb listings below. The headline ADR and revenue are the expected BOOKED figures — nearby asking prices corrected by our measured asking-to-booked factor (Portugal's calendar dataset is young, so this is a conservative estimate). Occupancy is the seasonality-adjusted full-year rate. The comp cards below show raw asking prices.

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.

Modelled from live Airbnb calendar data around this property · operating costs per line, editable in the P&L · estimates, not financial advice.Data sources & methodology ›

ROI calculations use Brixfox Intelligence rental data from live Airbnb calendar tracking — the Silver Coast dataset has been live since June 2026, seasonality-adjusted to a full-year estimate with a conservative calibration while it matures. Operating costs are modelled per line (management, channel fees, cleaning, utilities, IMI, maintenance, insurance). After-tax yields deduct non-resident IRS on AL income under the simplified regime (~8.75% of gross); buyer-side IMT and stamp duty are included in the all-in cost basis. Market factors in Portugal may impact actual yields.
