Zonaprop lists new-build projects — emprendimientos — as their own kind of thing, and the Actor treats them as a separate run rather than a filter over listings. That is a data modelling decision, and it is the right one for a reason worth spelling out.
What Zonaprop means by a development
Not a unit for sale, but a project: a building or a set of buildings, often in stages, with a feature set that describes the project rather than one apartment. Amenities, delivery stage, the range of unit types, the developer.
Why they cannot share a table with listings
A resale listing has one price, one area and one room count. A development has a range of each, or none yet. Force them into the same table and you get columns that are null on most rows and a shape nobody can query without a filter on entity type at every step — which is the same as having two tables, minus the clarity.
So entityType: "developments" is a separate run, and its dataset has one clean shape. The same reasoning applies to agencies, and it is the same reasoning that puts Nextdoor city rows in their own dataset.
Running a development sweep
{
"entityType": "developments",
"location": "capital-federal",
"maxItems": 150,
"proxyCountry": "mx",
"maxConcurrency": 3
}Everything else behaves as it does for listings: the same coverage ceiling, the same five-page robots.txt cap, the same non-Argentine proxy requirement. At $0.001 per development, the cost is negligible; the planning is the same.
New supply as a leading indicator
This is the analytical reason to track them. Resale listings describe the market as it is; new developments describe the market as it will be in two or three years. A neighbourhood with heavy new-build activity is on a different trajectory from one without, and no amount of resale data reveals that.
It is also a supply signal in the strict sense: a lot of new units arriving in a small area is downward pressure on rents there, later. That is one of the few property predictions with a mechanism behind it rather than a narrative.
Comparing developments with resale stock
Do it as two series, not one. Development pricing is often advertised as a figure to start from, for a stage, which is not the same object as an asking price for a specific resale unit — comparing them directly makes new build look cheaper than it is.
What the comparison supports, done carefully:
- New-build share by zone. Count developments against resale listings in the same
zoneto see where activity concentrates. - The premium, stated as a premium. Compare price per square metre with the caveat about starting figures attached, in the same sentence.
- Amenity drift. What new projects include tells you what the market will expect as standard in five years.
And keep the currency discipline from the two-currency guide: development prices are usually in dollars, which makes them comparable to sale listings and not to rents.
