New-Build vs Existing Property in Italy: Which Should You Buy?

Introduction

For most international buyers, the choice of region comes first and the choice of property comes second. But there is one decision that quietly reshapes the entire transaction: are you buying an existing property from a private seller, or a new-build from a developer?

The two routes have different taxes, different paperwork, different warranties, different financing dynamics, different timelines and different long-run economics. They also attract different buyer types. A wealthy DACH family looking for a turnkey lakeside apartment, a British retiree restoring a stone farmhouse, and an American remote worker buying an off-plan flat in central Florence are facing three different transactions even when the headline price is similar.

This guide explains the structural differences and helps you decide which route fits your use case.

The two routes, side by side

Neither route is universally better. The right answer depends on your priorities.

Tax treatment: where the headline number misleads

The biggest single-line difference is the purchase tax. Two buyers paying €400,000 — one for an existing apartment, one for a new-build — can pay materially different tax.

Existing apartment, second home, private seller, cadastral value €180,000:

• Registration tax: 9% × €180,000 = €16,200
• Fixed mortgage + cadastral: €100
• Total core tax: ~€16,300

New-build apartment, second home, developer, price €400,000:

• VAT: 10% × €400,000 = €40,000
• Fixed registration + mortgage + cadastral: €600
• Total core tax: ~€40,600

The new-build route carries roughly €24,000 more tax in this example. That’s the price of buying VAT’d new stock with current energy class, warranty and (usually) zero deferred maintenance.

For a luxury new-build (categories A/1, A/8, A/9), VAT becomes 22% — a punishing differential. For prima casa qualifying buyers, VAT drops to 4% on the new-build, often making the new-build the cheaper route on tax alone. The matrix:

For most foreign buyers — non-resident, second home — the existing-property route is cheaper on tax. The new-build route’s value lies elsewhere.

What the new-build actually buys you

A 10-year structural warranty

Italian law (Codice Civile Art. 1669 + Decree 122/2005) gives the buyer of a new-build a 10-year warranty against serious construction defects affecting the structure or the building’s stability. The developer must back this with a mandatory post-completion insurance policy (polizza decennale postuma) before the deed.

For foreign buyers without local repair networks or contractor relationships, this matters more than it does for a resident Italian. A roof problem in year 4 is the developer’s problem, not yours.

Energy class A and modern systems

A new-build in 2026 is built to the current NZEB (nearly-zero-energy building) standard. That typically means:

• Energy class A or A+ (vs E/F/G for many existing properties)
• Heat pump rather than oil/LPG boiler
• Photovoltaic on the roof (mandatory for new buildings of certain sizes)
• Modern insulation, triple glazing in northern regions
• Predictable utilities cost — often €1,000–€2,500/year for a 100 m² apartment, vs €3,000–€6,000 for an old un-insulated equivalent

Over a 20-year hold, the utility-cost differential alone can offset the higher VAT. If you also avoid a renovation cycle (often €1,500–€3,000/m² on older property), the new-build can be cheaper in lifecycle terms despite the bigger upfront tax bill.

Lower transaction friction

A new-build comes with fresh cadastral registration, current planning conformity, and an APE (energy certificate) issued for the building. The classic “cadastral non-conformity” deal-killer that haunts existing-property purchases simply doesn’t apply.

Customisation during construction

If you buy off-plan or while construction is in progress, you can usually negotiate finishes (flooring, kitchen, bathroom layout, sometimes wall position). Once the deed is signed on an existing property, every change requires permits, contractors and time.

What you give up by buying new

Tax cost (already discussed)

Material in most non-prima-casa scenarios.

Character

A new-build in Bolzano, Florence or Bari is usually well-built and energy-efficient — but it is rarely the kind of property foreign buyers come to Italy for. Stone walls, wood beams, terracotta floors, original frescoes, the patina of three centuries: these are existing-property attributes.

Location flexibility

New-build supply is concentrated in city peripheries, suburban developments and resort areas. The historic centres, the lakefront strips, the hilltop villages — by definition the most desirable locations — are almost entirely existing stock.

Resale identity

In ten years, your new-build will be a 10-year-old build competing against the next generation of new-builds. An existing 19th-century townhouse in Trastevere will still be a 19th-century townhouse in Trastevere, with whatever scarcity premium that commands.

Off-plan: the higher-stakes variant of new-build

Buying off-plan (acquisto sulla pianta or acquisto su carta) means signing before construction is complete — sometimes before it has begun. The economics can be attractive (developers offer pre-launch pricing of 10–20% below completed stock), but the risks are different.

What Decree 122/2005 mandates

Italian law requires developers selling residential property to private buyers off-plan to provide:

1. A fideiussione bond (bank guarantee or insurance bond) covering 100% of the deposit and any payments made before the property is delivered. If the developer goes bankrupt, the buyer can claim back every euro paid.
2. A 10-year post-completion insurance policy (polizza decennale postuma) issued before the deed.
3. Standardised contract clauses including completion timeline, technical specifications, payment schedule.

These are not optional. A developer who tries to take a deposit without a fideiussione is breaching mandatory law. Walk away — and report.

What you must check before signing

• Fideiussione issuer — verify it is a regulated bank or insurer, not a related-party shell
• Building permit (permesso di costruire) issued and in force, not pending
• Completion timeline with delay penalties for the developer
• Technical specifications annexed to the contract, line-by-line — finishes, brand of installed systems, square metres net vs gross
• Payment schedule linked to construction milestones, not arbitrary calendar dates
• Variation clause — what changes is the developer allowed to make unilaterally, and what triggers your right to walk away
• Snagging procedure at delivery, with retention against punch-list items

When off-plan goes wrong

The classic failures:

• Developer runs out of capital mid-build — fideiussione protects deposit but you’ve lost time
• Quality at delivery does not match technical spec — without an annex, you have weak recourse
• Completion delays of 12–24 months — unless penalty clauses are real
• Discovery at delivery that the unit’s net floor area is meaningfully smaller than advertised — common in poorly-drafted contracts

For off-plan purchases above €300,000 or for buyers without local presence, an independent Italian property lawyer is essentially mandatory. Spending €3,000–€6,000 on legal review to protect a six- or seven-figure commitment is rational.

Decision framework

Use the matrix to think through which route fits:

Most international buyers end up choosing existing for the second home and considering new-build only if (a) they qualify for prima casa at 4% VAT, (b) they specifically value energy class A and the warranty, or (c) they want a turnkey property with zero renovation friction.

A worked comparison: same buyer, two paths

A German lifestyle buyer, age 58, plans a second home near Lake Garda. Budget €600,000. Plans to use it 10–14 weeks/year, no rental.

Path A — Existing apartment, 110 m², lake-view, built 1985, partially renovated

• Purchase price: €600,000
• Cadastral value: ~€280,000
• Registration tax (9%): €25,200
• Notary + disbursements: €5,000
• Agent commission (3% + VAT): ~€21,960
• Translation, technical survey: €4,000
• Anticipated renovation in years 2–3 (kitchen, bathrooms, energy upgrade): €60,000–€90,000
• Annual carrying cost: €5,500 (IMU €2,200 + condominio €1,800 + utilities €1,500)
• All-in (Y1–3): €716,000–€746,000

Path B — New-build apartment, 105 m², partial lake view, completed 2026

• Purchase price: €600,000
• VAT (10%): €60,000
• Fixed taxes: €600
• Notary + disbursements: €5,500
• Agent commission (3% + VAT): ~€21,960
• Translation, light review: €1,500
• Anticipated renovation: €0
• Annual carrying cost: €4,200 (IMU €2,200 + condominio €1,500 + utilities €500)
• All-in (Y1–3): €689,560 + €12,600 carry = ~€702,000

In this comparison, the new-build is cheaper at the 3-year mark — primarily because the existing property carries a renovation overhang that the new-build does not. In a different scenario (smaller renovation, cheaper energy market, prima-casa eligibility) the existing-property route wins.

The lesson: do not compare purchase prices. Compare full lifecycle costs over your intended hold period.

What to ask before signing on either route

Existing property checklist

• Is the cadastral plan consistent with the actual layout? (Get a geometra to confirm in writing.)
• Are all renovations and additions properly permitted?
• What is the energy class, and what would it cost to bring to class B or A?
• Are there any condominio extraordinary works approved or upcoming?
• Are there outstanding IMU, TARI or condominio arrears?
• Is the seller the sole legal owner, with no co-heirs or pending succession?

New-build / off-plan checklist

• Is there a valid fideiussione covering my deposit, issued by a regulated entity?
• Is the polizza decennale postuma in place before deed?
• What are the exact technical specifications, line by line, annexed to the contract?
• What are the completion penalties for the developer?
• What is the capitolato (specification document) — and does it bind the developer?
• What’s my right to walk away if material variations occur?
• Has the developer completed similar projects? Can I visit them?
