On 26 October 2026, 771 apartments were for sale in Uccle. The median asking price is €440,000 and the median estimated rent €1,601 a month, a median gross yield of 4.4%. After registration duty (12.5%), notary fees, 5% vacancy and yearly running costs, the median net yield is 3.1%.
Half of the apartments have a net yield between 2.6% and 3.6%. For 54% of them the rent is estimated from rentals on the same street or within walking distance; 2% had to be approximated with our model. 13 listings are left out of the medians: prices that aren't comparable (life annuity, public sale, bundles without a unit count) or an implausibly high gross yield (above 8%).

For every listing we estimate the rent from comparable rental listings: first on the same street, then nearby, then city-wide, and only when that is not enough with a model. Gross yield is the annual rent divided by the asking price. Net yield accounts for registration duty, notary fees including VAT, 5% vacancy, property tax, insurance, service charges and maintenance, for a cash purchase. The median error of the rent estimate for apartments is 13.0%. Read the full methodology.
