Long-term rental Given the significant gap of 55.2% between the listing price of €430,000 and the fair value of €192,519, this penthouse is overpriced and not aligned with long-term rental expectations. The gross yield of 3.5% is below the typical return needed for sustainable investment in the current market. Family rental The property’s considerable overpricing at €430,000 compared to a fair value of €192,519 makes it unsuitable for family rental, as potential rental income does not support such a high acquisition cost. Though it has a decent condition rating of 81/100, the yield of 3.5% does not justify the investment. Buy-and-hold At a listing price of €430,000, substantially above the fair value of €192,519, the buy-and-hold strategy fails to present a compelling case, as the property is overpriced. The anticipated return is insufficient against the gap in value and yields, undermining potential long-term appreciation. Not ideal for Engaging in the luxury market is unwarranted for this property, given its overpriced nature and the lack of alignment with luxury buyer expectations. Additionally, short-term vacation rentals and student housing are not suitable given the market conditions and the yield being significantly restrained due to the high purchase price.
Tenant turnover risk High tenant turnover is a possibility due to a tenant stability score of 70/100, potentially leading to increased vacancy and re-letting costs.
