rua Engenheiro Adelino Amaro da Costa, 28
Area baseline €109,200 + condition +€6,459 + location +€8,299 = modelled fair value of €123,959 (€1,589/m²), a €106,041 (46.1%) gap versus the €230,000 asking price.
Long-term rental This property is not an ideal candidate for long-term rental due to its overpriced nature, with a fair value gap of 41.8%. The gross yield of 3.5% suggests that rental income may not sufficiently cover the elevated acquisition cost. Family rental While the apartment's size could appeal to families, the current pricing renders it less attractive, with a fair value of €133,778 compared to a listing price of €230,000. Additionally, the neighbourhood score of 69/100 indicates some potential drawbacks that may limit its appeal to family renters. Buy-and-hold Investing in this property as a buy-and-hold strategy carries risk, given that it is overpriced and lacks sufficient value appreciation potential. The 3.5% gross yield does not justify the investment, particularly in light of the significant fair value gap and the moderately rated neighbourhood. Not ideal for: Short-term vacation rental, Luxury market, Student housing
Economic and Tenant Volatility Risk: With both economic and tenant stability scores at 70/100, there is a moderate risk of fluctuations in rental income due to potential instability in the local economy and tenant turnover.
