Long-term rental The property's rapidly rising gap from its fair value suggests that it may not appeal to long-term tenants seeking value, with a yield of only 1.9% indicating limited return potential. Additionally, the condition and neighbourhood ratings do not sufficiently compensate for the high purchase price, making it a less attractive investment option. Family rental With a notable 43.4% gap between the listing price and fair value, this 3-bed duplex is likely overvalued for families looking for a reasonable rental opportunity. The modest yield alongside the neighbourhood's average quality implies that securing tenants may be challenging, further validating its overpriced status. Buy-and-hold Given the current listing price significantly exceeds its fair value, holding this property for future appreciation poses considerable risk due to its 1.9% yield and mediocre condition. Investors seeking steadfast returns should approach this asset cautiously, as its high price could hinder long-term profitability.
Economic Vulnerability The economic stability score of 80/100 indicates a relatively strong economy, but the tenant stability score of 75/100 suggests that there may be fluctuations in tenant demand that could impact rental income.
