In the Portuense zone, on via Prospero Colonna, an ordinary residential home in normal condition sells for between €2,600 and €3,700/m² of gross floor area and rents for between €10.8 and €15.3 per m² per month. These are the OMI property values (quotazioni OMI) of the Italian Revenue Agency (Agenzia delle Entrate), meaning the average values that the Agency publishes every half-year, zone by zone, with a minimum and a maximum for homes in normal condition. The data is from the 1st half of 2026.
Economy-type homes cost a little less: sale between €2,350 and €3,400/m², rent between €10.0 and €14.8 per m² per month. Garages (box) and parking spaces cost much less: a box ranges from €1,400 to €2,000/m², and an uncovered parking space from €600 to €900/m².
Compared with the other zones of Rome, the Portuense is in the upper part. For the maximum price of ordinary residential homes it ranks 85th out of 213 zones in the municipality, ordered from the most expensive. The median of the municipal maximums is €3,300/m², while the maximum for this zone reaches €3,700/m². If you are looking at an auction here, the reference value for an ordinary home in normal condition is therefore between €2,600 and €3,700/m².
As of 5 November 2026, our auction archive, which starts from 15 October 2026, counts 3 lots in this zone, all of them homes. For all three, sale attempts are scheduled that have not yet taken place: at the moment no auction with no bids (asta deserta) or awarded lot is recorded. These numbers will grow, so always check the date before you trust them.
Before deciding, compare the base price (prezzo base) of a lot with the OMI ranges above.
