Long-term rental The 3-bed apartment in Cascais e Estoril is fairly priced at €1,390,000, with a fair value of €1,439,196, resulting in a narrow 3.4% gap. With a gross yield of 3.7% and solid family amenities nearby, this property can offer steady rental income in a stable economic context. Family rental Priced at €1,390,000 and with a fair value of €1,439,196, this apartment is a reasonable option for families seeking quality living space in Cascais e Estoril. The gross yield of 3.7% reflects its appeal in a neighbourhood rated 70/100, supporting a demand for family rentals. Buy-and-hold The property stands at a fair price of €1,390,000, slightly below its fair value of €1,439,196, indicating a sound investment for long-term holding. A gross yield of 3.7% suggests potential for stable returns while benefiting from Cascais e Estoril's proximity to Lisbon and high tenant quality. Short-term rental Although marketed in a suburban area with family amenities, this 3-bed apartment is not ideal for short-term rentals due to its relatively high price of €1,390,000 and a fair value just slightly above. The expectation of lower turnover and fluctuating demand in this setting makes it a less viable option for generating rapid rental income. Luxury market The apartment, listed at €1,390,000, is not positioned as a favorable luxury investment given its fair value slightly hinges at €1,439,196. With its gross yield of 3.7% and more modest condition rating of 78/100, it does not align with high-end market expectations.
Tenant turnover risk Tenant stability at 70/100 indicates potential for increased turnover, which can lead to higher vacancy rates and costs associated with re-letting the property.
