Long-term rental The property, priced at €4,000,000, is significantly above the estimated fair value of €2,817,937, indicating a 29.6% premium that detracts from its potential as a long-term rental investment. With a gross yield of 0% and condition rating of 68/100, the investment prospects appear unappealing for generating consistent rental income.

While the neighborhood has a decent rating of 72/100, the excessive price diminishes the attractiveness for families seeking affordable long-term housing.
