Roiano or San Giacomo: how to compare the two Trieste districts

There is no single answer at district level: in Trieste two flats on the same street can be worth very different sums. Here is the checklist to fill in for each property, and the documents to gather before you buy or sell.

Roiano or San Giacomo: can you say which one is the better deal?

No, not from the name of the district. Anyone asking "is Roiano better than San Giacomo" is looking for an answer the market doesn't give, because in Trieste two flats on the same street can be worth very different sums. The useful comparison is not between two neighbourhoods, it's between two specific properties: this floor against that one, with or without a lift, with new heating or with a 1990 boiler, with a building in good order or a façade waiting to be redone.

So the question needs rewriting: what do I have to check, in both areas, before deciding? The list starts here. It works if you're buying, and it works the other way round if you're selling: same points, seen from the other side of the table.

What really changes from one district to the other, and what doesn't

What changes is the setting: how you get there, where you park, what you have downstairs, how much noise comes through the window. The rules don't change. The documents you need in order to sell are the same across the whole city, conformità catastale is checked in the same way, the APE is drawn up on the same criteria.

What does shift from one area to the next is how much the market will pay for the same square metre. And there the district name is only the first layer. Underneath sit the floor, the aspect, the year the building went up, the state of the systems, whether there's a lift, the service charges. A bright second floor with a lift and a fourth floor without one are not in the same league, even in the same building.

One thing that weighs more in Trieste than on flat ground: the slope. Before you fall in love with a flat, walk the stretch between the front door and the stop of the transport you'd use every day, and do it carrying the shopping. Then decide.

What exactly do I compare two flats on?

This is the grid to fill in for each of the two properties you're weighing up. If a box stays empty, you don't yet have enough to decide.

What to check Why it matters Where to ask
Floor and lift Changes both the value and daily life Viewing; assembly minutes if a lift project exists
Aspect and light Judged only in person, never from photos Viewings at different times of day
Type of heating and condition of the boiler First cost item after the mortgage Boiler logbook (libretto di impianto), building manager
Energy rating (APE) Compulsory document for a sale, and the first clue on running costs Seller or agency, before you negotiate
Annual service charges A good price with high charges isn't a good price Latest accounts from the building manager
Works approved or under discussion If the roof or façade needs doing, someone pays Minutes of the last assemblies
Cadastral and planning compliance If the floor plan doesn't match what you see, the rogito stalls Visura and cadastral plan, building permit
Cellar, attic, parking space Often taken for granted and missing from the paperwork Seller's purchase deed, floor plans

Two lines of explanation, because these aren't obvious words. The visura catastale is the extract showing how the property is registered at the Land Registry: owner, identifying data, rateable value. Conformità catastale is the match between the plan filed at the Land Registry and the flat as it actually is: if a bathroom was moved or a balcony enclosed and nobody updated it, that gap has to be fixed before the rogito, the deed signed by the notary that transfers ownership. The APE is the Attestato di Prestazione Energetica, the energy performance certificate: it states how much the property consumes and must be attached to the sale.

How is the price set, if the district doesn't set it?

The price comes out of three things crossing: what similar properties in the same area are asking, what has actually sold (a different number, often lower than the asking price), and how much work the buyer needs to do to make the place liveable the way they want it.

That's why you won't find a price per square metre here for Roiano or for San Giacomo, and you won't get a figure even if you phone us first. A number given over the phone, without having seen the floor, the light, the systems and the assembly minutes, is a guess dressed up as a valuation. It does damage both ways: too high and the property sits still for months, too low and you give money away.

What you can do today: gather the documents in the list above and put them in one folder. Whoever values your flat with those papers in hand gives you a figure you can defend in negotiation. Whoever values it without will give you a figure to revise the moment a buyer turns up with the bank's surveyor.

I'm selling the family flat in one of the two districts: where do I start?

With the paperwork in order, before the photographs. In this order:

  1. Find the title under which the property came into the family: purchase deed, gift or inheritance.
  2. Request the visura and the cadastral plan, then compare it with the real rooms, tape measure in hand.
  3. Check whether work was done over the years without a building permit: this is the point that stops most negotiations.
  4. Ask the building manager for the latest accounts, the recent minutes, and whether any works have been approved.
  5. Have the APE drawn up.
  6. If there are several heirs, put in writing who signs what before the listing goes online.

If one of these points is uncovered, sort it first. A property put online with an irregularity still to be regularised reaches the preliminary contract and then runs aground, and the lost time costs you credibility: after a few weeks buyers read an old listing as a listing with something wrong in it.

When is it better not to sell right now?

When the documents aren't in order and you haven't decided who pays for putting them right. When the heirs don't agree on a minimum price: the listing goes out, an offer arrives, and the negotiation dies inside the family. When the building is discussing major works and the amount isn't known yet: better to know the figure and negotiate over it than to discover it in the middle of a preliminary contract.

In all these cases, the month that feels wasted is the month that saves the price.

What should I ask an agency before signing anything?

Four questions, and they work for any agency, not only for us:

  • Which comparable properties is your valuation based on, and are those asking prices or completed sales?
  • How long does the mandate last, and what happens if I don't sell?
  • Which documents am I missing, and who obtains them?
  • What does it cost me, exactly, and when do I pay?
