Quick answer: The decision between these two cities is not about yield. It is about whether you are willing to buy a property whose legal status is still being determined by a municipal office. In Rome that is a live possibility on a large share of the stock; in Milan it is rare.
Comparisons of these two cities are usually written about rental yields and prestige. Both are real and both are secondary to a question that decides whether a purchase is safe: does this property have a settled legal status, and can the seller prove it.
The rule, stated plainly
Buy in Milan if you need certainty at completion. The stock is younger, it was built under permits rather than regularised afterwards, and a purchase closes with a documentary position that is either clean or clearly not.
Buy in Rome if you can price and manage an open file. The city offers locations, buildings and a depth of historic stock that Milan does not have, and a share of that stock is discounted precisely because most buyers will not take on the administrative work.
The condition that reverses it: a Rome property whose amnesty was completed and whose permit in amnesty was issued carries none of this. On that specific property, the distinction between the two cities disappears entirely, and the comparison returns to the ordinary ones about yield, liquidity and taste.
What the amnesties were
Italy legislated three general building amnesties: law 47 of 1985, law 724 of 1994 and law 326 of 2003, with Lazio adding its own regional measure in 2004. Each allowed owners of unauthorised works to apply for regularisation, paying a charge and, on approval, receiving a permit in amnesty that made the works lawful.
The application is not the permit. Filing the request, paying the initial sums and receiving a stamped receipt establishes that a process was started. It does not establish that the process ended, what it concluded, or what the office may still require.
| Stage | What it means | What the buyer can rely on |
|---|---|---|
| Application filed | The owner asked to regularise | Very little |
| Documents supplemented | The office asked for more | Progress, not resolution |
| Permit in amnesty issued | The works are lawful | The whole point |
| Application refused or lapsed | The works are not lawful | A problem the buyer would inherit |
Why Rome is the extreme case
Volume. Rome received applications in the order of 600,000 across the amnesty laws, and roughly a third of them are reported as still requiring processing and the issue of the corresponding permit. Thousands have sat unresolved for decades.
Nothing about that is unique to Rome in kind; it is unique in scale. A municipal technical office cannot examine hundreds of thousands of files quickly, and the ones that were straightforward were dealt with first, leaving the complicated ones behind.
The city has responded. Rome Capitale has activated a simplified procedure covering pending applications under all the relevant laws, run through a digital platform at the building services office, which gives an owner or a purchaser a defined route to closure rather than an indefinite wait.
That matters for the decision this page is about, because it converts an open-ended risk into a project with a process behind it. It does not make the risk disappear.
Why Milan looks different
Milan’s residential stock is dominated by post-war construction, by the expansion of the 1960s and 1970s, and by more recent regeneration on former industrial land. That fabric was built under permits, in a period when municipal control was tighter, and there is far less of the accumulated informal alteration that the amnesties were designed to absorb.
Milan has other problems and this comparison should not pretend otherwise. Prices are the highest in Italy, yields on prime residential are thin, and the buyer competes with domestic and institutional capital rather than with other foreigners. What Milan does offer is that a purchase there is generally a question about price rather than a question about status.
How to run the check in Rome
The general Italian file is set out in the due diligence guide. In Rome, five specific steps sit inside it.
- Ask directly whether any amnesty application affects the property, and obtain the protocol number rather than a description
- Instruct a local technician to obtain the file from the building services office and report on its state
- Establish what remains outstanding: documents, payments, works, or a decision
- Price that outstanding work and agree in writing who carries it
- Make production of the permit in amnesty, or the technician’s report, a condition of the offer
Step one is the one buyers skip, because they assume a seller would volunteer it. Sellers with closed files volunteer immediately, since it is a selling point. Silence is information.
What it costs to get it wrong
Three costs, in ascending order.
The mildest is delay. A purchase held up while a file is closed is inconvenient and survivable.
The middle case is money. Outstanding charges, additional works to bring the property into line with what was applied for, and professional fees all fall on whoever owns the property when the office finally reaches the file.
The worst case is that the works cannot be regularised at all, in which case the buyer owns a property with unlawful elements, cannot easily sell it, cannot readily mortgage it, and may face an order to restore. The selling guide sets out what a vendor has to produce, and a vendor who cannot produce it is in a weak position.
What a technician’s report should tell you
Instructing someone to look at the file is only useful if the instruction is specific. A report worth paying for answers five questions in writing.
What was applied for, under which law, and on what date. That establishes which regime governs the file and how long it has been open.
What the office has done since. Requests for documents, partial payments, site inspections and any communications are the record of whether the file is moving or dormant.
What remains outstanding. Documents, charges, works, or simply a decision, and an estimate of each.
Whether the works as they stand match what was applied for. A file that describes an enclosed balcony while the flat contains an enclosed balcony and a converted attic is a file that will not close as it is.
Whether the amnesty is capable of succeeding at all. Some works fall outside what the amnesties could regularise, and that answer changes the purchase from a project into a refusal.
- Insist on a written report, not a verbal reassurance
- Require the protocol number, since a report without one is about nothing in particular
- Ask specifically whether the works as built match the application
- Get the estimate of outstanding cost before agreeing a price
How this shows up in negotiation
Once a buyer can quantify the position, the file becomes a negotiating instrument rather than a hazard.
A seller with a closed file has nothing to negotiate about and will say so. A seller with an open file has a property that a well-advised buyer will value lower, and the discount should reflect the cost of closing it plus the risk that it does not close. Sellers who have never been asked the question often do not realise their position is weaker than the asking price assumes.
The alternative structure, common in practice, is for the seller to undertake to close the file before completion, with the deposit held and the deed conditional. That works where the file is close to resolution and is unrealistic where it has been dormant for twenty years.
What each city is actually for
Set the document question aside for a moment, because the two cities do genuinely different jobs.
- Milan is a working financial and professional centre with year-round corporate rental demand, the deepest resale market in Italy and the least seasonal economy. Its risk is price, not paperwork.
- Rome is a capital city with an administrative economy, an enormous visitor flow and a historic centre of a scale nothing else in Italy approaches. Its risk is that the stock carrying the charm is the stock carrying the history.
For a buyer whose objective is straightforward income, Milan is the simpler proposition and the Milan guide sets out its districts and their pricing. For a buyer who wants the historic centre, the Rome guide covers the city and Rome’s centro storico treats the core in detail; Milan’s Navigli is the nearest Milanese equivalent in character.
The rest of the comparison, briefly
Everything above concerns one document. The two cities differ on much else, and a buyer should know the shape of it before deciding which risk to take.
Demand. Milan’s residential demand is professional and year-round, driven by an economy that employs people from across Italy and abroad. Rome’s is administrative and touristic, with a large public sector and a visitor flow that has no equal in the country but is concentrated in specific districts.
Prices. Milan is the most expensive market in Italy and Rome is cheaper per square metre in most comparable districts, which is the reason many foreign buyers start with Rome.
Yields. Milan’s gross yields on prime residential are thin because prices are high. Rome’s are higher on paper and the difference narrows once the management intensity and the void risk of a tourist-facing property are priced.
Liquidity. Milan is the deepest resale market in Italy, with domestic and institutional buyers competing. Rome’s is deep in absolute terms and shallower per district, since the historic centre and the periphery behave as separate markets.
Time. Milan’s transactions move faster, in part because the documentary position is usually simpler. That is the same point this page has been making, expressed as calendar rather than as risk.
What the amnesty era left behind more broadly
It is worth understanding why so much Italian property carries this history, because it explains why the question is not an accusation against Rome.
Italy urbanised quickly in the decades after 1950, and building control did not keep pace with construction. Extensions, enclosures, conversions of attics and basements, and in some places whole buildings went up without permits. The amnesties were the state’s response: rather than demolish, offer regularisation on payment.
Three rounds of that produced millions of applications nationwide. Cities with the largest stock of older buildings and the fastest post-war growth received the most, and Rome combined both. Milan grew fast too, but its growth was more heavily planned and more of it took the form of large developments rather than incremental private alteration.
The practical inference for a buyer is that this is a question about a specific building rather than a judgement about a city. A 1970s block in Milan built by a single developer under one permit is documentary simple; a Roman palazzo divided and redivided across a century is not, and neither fact says anything about the quality of the property.
Which buyer belongs where
A first-time foreign buyer with no Italian advisers in place is generally better served by Milan, because the failure modes are financial rather than legal and a mistake there costs money rather than years.
A buyer with a good Roman lawyer, a technician they trust and the patience to run an administrative process is better served by Rome, because the discount available on stock with an open file is real and the work required to close it is finite.
A buyer who wants the Roman historic centre and has neither of those should get them before making an offer, not after.
Renovation and the amnesty question together
There is a specific trap worth naming, because it catches buyers who intend to renovate.
A renovation project requires the existing state of the building to be lawful before new works can be authorised. Where an amnesty file is open, the technician designing the project cannot certify the starting point, and the project stalls. That is why the amnesty question is not merely a title issue for a passive buyer; it is the gating item for anyone planning work.
The renovation cost guide covers what the works cost. Establishing that the works can be authorised at all comes first, and in Rome that means closing the file before designing anything.
For the other Roman comparison worth reading, the Florence and Rome comparison sets out a different and equally invisible restriction that hides in the deed chain rather than in the planning office.
Frequently Asked Questions
If you need the legal status of the property to be settled at completion, buy in Milan. If you can price an open amnesty file and manage it to a conclusion, Rome offers stock and locations Milan cannot match, at a discount that exists precisely because most buyers will not do that work.
Italy ran building amnesties under the laws of 1985, 1994 and 2003, under which owners of unauthorised works could apply to regularise them. Rome received in the order of 600,000 applications, a volume no municipal office could process quickly, and roughly a third are reported as still awaiting the issue of the permit in amnesty.
It means the works were declared but the regularisation was never completed, so the property sits between unlawful and lawful. A seller can produce the application receipt and cannot produce the permit, and the buyer inherits whatever the outcome turns out to be, including any further payments or works the office requires.
Frequently yes. Rome Capitale has activated a simplified procedure covering pending applications under all the relevant laws, accessible through a digital platform at the building services office. Closing a file takes a technician, documents and time, and the practical question for a buyer is who does that work and who pays for it.
Its stock and its history are different. Milan's residential fabric is dominated by post-war construction and by later regeneration, built under permits rather than regularised afterwards, so the volume of legacy amnesty files is far smaller. Milan has its own problems, and this is not one of them.
It shows up in the discount a careful buyer can negotiate and in the risk an incautious one absorbs. Two Rome apartments in the same building can be worth materially different sums depending on whether the amnesty file was closed, and that difference is invisible in a price per square metre.
A condition requiring production of either the permit in amnesty or a technician's report on the state of the pending application, before the deposit becomes committed. Sellers who have closed their file produce it immediately. Sellers who have not will explain why the question does not matter, which is the answer.
Yes, and it is common. A Rome property whose amnesty was completed and whose permit was issued carries none of this, and the buyer of one is in the same position as a buyer in Milan on this specific question. The point is not that Rome is unsound; it is that in Rome the question has to be asked.
