The valuation. The asking price of €550,000 is significantly above the fair value of €314,594, representing an excess of €235,406, or 42.8%. This property is therefore considered overpriced.

A strategy focused on aesthetic upgrades could elevate interest and yield a positive return. Buy-to-let angle. The estimated rental income stands at €2,108/month, yielding approximately 4.6%. This makes the property suitable for long-term family rental, particularly appealing in its semi-rural location near urban amenities.

Ericeira, Mafra, Lisbon
Area baseline €672,786 + condition -€6,328 + location +€0 = modelled fair value of €314,594 (€1,942/m²), a €235,406 (42.8%) gap versus the €550,000 asking price.
Long-term rental The property is not suitable for long-term rental due to its overpriced nature, with a valuation gap of 42.8%. Additionally, the gross yield of 4.6% does not compensate for the high purchase price relative to fair market value. Family rental Given the property's listing price of €550,000, it stands out as overpriced, exceeding its fair value by 42.8%. The lack of adequate neighborhood amenities and lower tenant quality may further deter family rentals at this price point. Buy-and-hold This property is overpriced and does not present a sound buy-and-hold investment given the substantial gap of 42.8% from fair value. The combination of poor condition ratings and a less desirable neighborhood diminishes its long-term appreciation potential.
Economic Vulnerability With an economic stability score of 50/100, the property is exposed to potential fluctuations in local economic conditions that may negatively impact rental income.**
