A foreign owner comparing agencies for a Rome property cannot walk into the office and read the room, so the criteria that actually decide a good choice have to work from a distance: a registration number, an insurance certificate, a stated process for discretion, rather than an impression formed in a meeting. Every real-estate intermediary in Italy operates under the same regulatory floor, which means the real work of choosing is verifying that floor was met, then judging what sits above it: market specialization, discretion practice, and a track record you can actually ask to see.
What Separates a Luxury Agency from a Generalist Office in Rome
The legal regime is identical for both: every intermediary registered to practise real-estate mediation in Italy, whether the office lists a two-bedroom apartment or a historic palazzo, sits under the same rules. What separates a prime specialist from a generalist office is scope of practice, not licensing status. A firm working exclusively in the top segment of Rome’s market builds narrower expertise: which OMI zones carry the highest quotations, which buyers actually transact at that level, and the paperwork specific to protected or listed buildings. That is a reasonable thing to probe for in a first conversation, and the compliance checks below are worth running with the same rigor whatever the size of the office.
What Documents Should You Ask an Agency to Show You?
Four things, and each one is verifiable rather than a matter of taking the agency’s word. First, registration: practising real-estate mediation in Italy requires a SCIA (Segnalazione Certificata di Inizio Attivita) filed with the Registro delle Imprese at the Chamber of Commerce. The old Ruolo degli agenti d’affari in mediazione was abolished by decree in 2010 and replaced by registration in the Registro delle Imprese and the REA under the decrees of 26 October 2011, though the underlying professional requirements of Legge 39/1989 were left unchanged, according to the Camera di Commercio di Modena. As the law currently stands, the owner, every legal representative, and every preposto of the firm must hold an upper-secondary diploma, have attended a specific training course, and have passed an examination at the Chamber of Commerce testing capability in the branch of mediation practised.
Second, insurance. Article 3, paragraph 5-bis of Legge 39/1989 requires every mediatore to carry professional indemnity insurance covering professional risk and protecting clients, extending to everyone within the firm who carries out mediation in any capacity. Since 1 January 2018, practising in breach of that obligation has carried an administrative fine of 3,000 to 5,000 euro under the 2018 Budget Law. Ask to see the certificate; it is not confidential information.
Third, the personal identification card. Anyone practising mediation on a non-occasional basis is entitled to a tessera personale di riconoscimento from the Chamber of Commerce, valid four years, showing the registration date and the expiry date. If a firm uses standard forms for its mandates, those forms must show the firm’s REA number and codice fiscale, and copies must be deposited with the Registro delle Imprese before use.
Fourth, conflict of interest. Article 5, paragraph 3 of Legge 39/1989, in the text updated to 12 August 2022, makes mediation incompatible with running a business that produces, sells, represents or promotes goods in the same merchandise sector, and incompatible with any situation of conflict of interest. An agency holding an undisclosed stake in a related business in the same sector sits outside that rule, so asking whether any such holding exists is a fair question to put directly.

How Long Should an Exclusive Mandate Last?
Italian law sets no standard duration for an exclusive mandate: the length is a negotiated contractual term, not a statutory default, so there is no fixed period to check an agency’s proposal against. What the law does constrain is how that term gets agreed. Where an exclusivity, irrevocability, or tacit-renewal clause is drafted unilaterally by the agency and not individually negotiated with a consumer seller, it can be assessed as unfair (vessatoria) under article 33 of the Codice del Consumo. In practice, that means the duration should be something you discussed and adjusted, not boilerplate you signed because it was already in the draft. If an agency will not move on the term at all, that refusal itself is worth raising, and it sits close to the errors covered in mistakes to avoid when selling a luxury property in Rome.
How Commission Works Under Italian Law
Commission follows result: under article 1755 of the Italian Civil Code, a mediatore is entitled to a commission from each party if the deal is concluded as a result of the mediatore’s intervention. The law sets neither the amount nor the rate, so any figure quoted to you is a commercial term to be agreed rather than a fixed cost. What is worth settling before you sign is what the agency’s intervention will actually consist of, and whether the party proposing it has any competing stake in the transaction under the incompatibility rule above.
Why Discretion Belongs in the Selection Criteria
Discretion is a working requirement for a certain type of transaction, not a marketing adjective, and it is the one criterion here that cannot be checked against a public register. A high-value Rome property often needs to move off the open portals: no address in the listing, photography that avoids identifying features, a buyer list that is qualified before a viewing is arranged. None of that can be verified from a certificate the way a REA number or an insurance policy can. What you can do is ask the agency to describe its actual process before you sign anything: how a property is kept off public search results, how buyers are pre-qualified, who inside the firm sees the file. An agency that answers with a concrete workflow is telling you something different from one that answers with the word discreet and stops there. Put that question in the mandate discussion alongside the documentary checks above, not as an afterthought once the paperwork is settled.

What the Data Says About Rome’s Prime Market
Two public data sources give an owner a starting reference, though neither substitutes for an individual valuation. The Osservatorio del Mercato Immobiliare (OMI) of the Agenzia delle Entrate publishes, twice a year and for every OMI zone of a municipality, a minimum-to-maximum quotation range in euro per square metre, free to consult online. The figures currently in force cover the second half of 2025 and were updated on 16 March 2026. The Agenzia delle Entrate is explicit that these quotations do not replace a valuation of the individual property and give only broad indications, so treat them as an indicative range, not a price.
For the prime segment specifically, the Market Report Italia 2026 by Engel & Volkers, produced with scientific support from Nomisma and presented on 8 April 2026, put Rome’s historic centre prime segment between 6,000 and 10,000 euro per square metre, reaching 12,000 euro per square metre for new or fully renovated stock, with prime prices growing between 1% and 3% between 2024 and 2025. An agency working the prime segment day to day should be able to place your property within that range and explain why, rather than quoting a single number without context. For a fuller look at how that number gets built, see how a luxury property in Rome is actually valued.
Generalist Office vs Prime Specialist: What to Probe For
The regulatory baseline is identical for both, so the table below is not a scorecard but a list of what to ask each of them, and where a specialist should be able to answer more precisely.
| What to ask about | Generalist office | Prime specialist |
|---|---|---|
| Registration and insurance | Same legal minimum applies | Same legal minimum applies |
| Market focus | Ask which price bands and areas the office actually transacts in | Expect a narrow segment and named OMI zones |
| Buyer pool | Ask how buyers reach the listing | Expect buyers pre-qualified at the relevant price point |
| Discretion | Ask what happens if the property must stay off the portals | Expect a describable workflow, not a reassurance |
| Market data | Ask which sources the price is based on | Expect OMI zone data plus prime-segment reporting |
How Trevi Elite Works With International Owners
For an owner outside Italy weighing a mandate, Trevi Elite puts a specific offer on the table: a documentary compliance check on request, a written valuation grounded in OMI zone data and prime-segment benchmarks rather than a single asking-price guess, and a discretion process built around qualified buyers before a listing goes anywhere public. Behind that sit, on the firm’s own figures, independent strategic counsel to property owners since 2006, more than 200 clients across the US, EU and CIS, more than 100 investment and hospitality assets, and over 150 million euro in total transacted property value. The firm is affiliated with FIMAA. If you are comparing agencies before granting a mandate on a Rome property, write to Trevi Elite for that compliance check and valuation, or read how the process runs from first conversation to closing on the seller service page; the guide on selling a luxury home in Rome covers timeline, paperwork and discretion in more detail.
