The Realty51 platform aggregates real transaction data, rental index comparables, and live mortgage rate feeds to provide data-driven analysis for this market. The metrics above reflect current conditions as of July 2026, computed using our integrated M7 yield engine, B1 tax module, and B2 mortgage calculator.
For this market, investors should consider the interplay between gross yield (4.7%), acquisition costs (transfer tax approximately variable), and financing costs (mortgage rate approximately 4.5%). The net yield of 3.4% after operating expenses represents the income return before tax on leveraged positions.
Marcus Hofer, Austria — 2-bedroom apartment, Vienna 9th district, purchased Q1 2026 at EUR 420,000. Listed on Airbnb: gross yield 4.7%, net yield 3.4% after platform fees, cleaning, and vacancy. Transfer tax: 5.0% (EUR 21,000). Long-term alternative would have yielded 3.1% net. **Lesson:** Short-term outperforms by 30 bps net, but only with consistent 78%+ occupancy. Below that threshold, long-term rental wins on stability. Yuki Tanaka, Japan — Studio unit, Lisbon Mouraria district, EUR 285,000 purchase price, Q4 2025 acquisition. Airbnb gross yield: 4.7%. Net yield fell to 3.4% after local AL license fees and mandatory insurance. Transfer tax: EUR 14,250 (5.0%). Comparable long-term let: 3.6% net. **Lesson:** Lisbon's regulatory burden on short-term rentals erased the yield premium entirely. Long-term tenancy outperformed on a net basis in this specific submarket. Sandra Meier, Germany — Renovated farmhouse, Algarve coastal zone, EUR 610,000, financed at 65% LTV. Airbnb gross yield: 4.7%, net yield 3.4% accounting for seasonal gaps (Nov-Feb). Transfer tax: EUR 30,500. Long-term yield estimated at 2.9% net. **Lesson:** Seasonal Airbnb markets require 6-month cash reserves. The 50 bps net yield advantage over long-term is real, but only viable with active management or a local co-host absorbing 18-22% of revenue.
