alameda Fonte Velha
Area baseline €405,594 + condition +€6,202 + location +€37,315 = modelled fair value of €449,110 (€2,376/m²), a €340,890 (43.2%) gap versus the €790,000 asking price.
Long-term rental The property is currently overpriced at €790,000, with a fair value assessment indicating it should be valued at only €449,110, creating a significant gap of 43.2%. The current yield of 4.4% gross does not compensate for the inflated price, making it a less attractive long-term rental option. Family rental This 4-bed apartment in Sintra is priced at €790,000, which is considerably above its fair value of €449,110, a 43.2% disparity. While the property has decent schooling access, the overall price does not align with the local family's rental budget expectations, rendering it overpriced. Buy-and-hold With a listing price so far above fair value at €790,000 versus €449,110, or 43.2% overpriced, the investment potential is severely compromised. The current market conditions and property yield of 4.4% gross suggest that holding onto this investment may not yield satisfactory returns over time.
Tenant default risk With a tenant stability score of 65/100, there is a notable risk of tenant default that could affect rental income.
