This tutorial shows how to scrape Portal Inmobiliario property detail pages into CSV with the Portal Inmobiliario Detail Scraper for UScraper. You will prepare URLs, import the workflow, validate fields, and handle access issues before scaling.
Scope
Prerequisites for a Portal Inmobiliario scraper
You need UScraper installed as a local desktop app, the Portal Inmobiliario Detail Scraper template, a reviewed list of property detail URLs, and a local folder for the CSV export. Start with three to five URLs so you can confirm access, page shape, exported columns, and duplicate behavior before a larger batch.
This guide is for selected detail pages, not automated account actions, private seller data, login flows, CAPTCHA bypassing, or broad crawling from Portal Inmobiliario mapa search results. It can work for detail URLs from portal inmobiliario arriendo or portal inmobiliario venta pages as long as the final input is an individual property page.
Review the current Portal Inmobiliario terms and conditions, help material, and your internal data-use policy before automation. If you need governed access, Mercado Libre publishes real estate developer resources, including a real estate API guide.
A page loading in your browser is not the same thing as permission to automate, store, redistribute, or resell the data.
Workflow
How the Portal Inmobiliario detail workflow works
The JSON export is the authoritative workflow definition. It does not paginate inside a detail page. It loops through configured property URLs, waits for each page, injects a parser, writes a row, and continues to the next input.
| Block | What it does | What to check |
|---|---|---|
| Navigate | Stores the detail URL list | Replace sample links with reviewed property URLs. |
| Wait for Page Load and Sleep | Gives the listing time to render | Stop if the browser shows an error or verification page. |
| Inject JavaScript | Adds fallback preview rows for known sample URLs | Do not treat fallback rows as fresh market data. |
| Wait for Element | Confirms the page body exists | A body can still be a verification screen, so inspect status. |
| Structured Export | Extracts fields into CSV columns | Confirm filename, headers, append mode, and folder. |
| Loop Continue | Advances to the next URL | One output row should trace back to one input URL. |
If Portal Inmobiliario redirects to Mercado Libre account verification, the template can use embedded preview data for bundled sample URLs and marks estado_acceso accordingly. That makes the CSV shape visible, but production rows should be verified against accessible live pages.

How to scrape Portal Inmobiliario detail pages to CSV
Import the template
Open the Portal Inmobiliario Detail Scraper, download the JSON, and import it into UScraper.
Prepare detail URLs
Collect individual property detail URLs first. Do not paste search pages, map pages, saved filters, or account-only links into this workflow.
Replace Navigate inputs
Open the Navigate block and replace the bundled sample URLs with your reviewed Portal Inmobiliario detail links, one property per URL.
Confirm page access
Open one target URL in the same browser context. Continue only when the real listing renders, not a Mercado Libre verification, login, or error page.
Set the export path
In Structured Export, confirm portal_inmobiliario_detalles_scraper.csv, include headers, append mode, and the local saveLocation for your project.
Run a short validation batch
Export a few rows, compare them against the browser, then scale the URL list only after estado_acceso and key fields look correct.
Because the workflow appends rows, repeated tests can create duplicates. Use a dated folder, clear the file before reruns, or deduplicate by url_inmueble.
Validation
Validate Portal Inmobiliario data extraction
Portal Inmobiliario data extraction is only useful when the CSV can be audited. Open the export beside the input URLs and check a few records across the run.
| Check | Compare | Why it matters |
|---|---|---|
| Listing identity | proyecto and url_inmueble | Confirms the row belongs to the intended property. |
| Commercial fields | precio, superficie_util, and banos | These fields often drive valuation, filtering, and market analysis. |
| Location | ubicacion | Empty location can mean hidden markup, changed layout, or a verification page. |
| Seller fields | contacto and corredora | Helps separate developer projects, agencies, and individual advertisers. |
| Access status | estado_acceso | Flags rows created from accessible pages versus verification or preview fallback. |
If many rows are blank, pause the batch. Check for verification screens, tracking redirects, removed listings, or markup changes before adding more URLs.

Troubleshooting
Common issues in Portal Inmobiliario scraping
| Symptom | Likely cause | Fix |
|---|---|---|
estado_acceso says verification | Mercado Libre account verification appeared | Stop the run and use an approved access path. |
Blank precio or proyecto | Detail markup did not render or selectors changed | Inspect one page, then adjust waits or selectors. |
| Duplicate rows | Append mode plus repeated test runs | Clear the CSV or deduplicate by url_inmueble. |
Empty ubicacion | Address is hidden, absent, or loaded differently | Treat it as optional and validate several page types. |
| Search page exported as one row | A Portal Inmobiliario mapa or result URL was supplied | Replace inputs with individual property detail URLs. |
FAQ
Portal Inmobiliario scraper FAQ
Portal Inmobiliario pages may be visible in a browser, but automated collection can still be limited by platform terms, privacy rules, database rights, robots directives, and anti-abuse systems. Review current rules, avoid bypassing access controls, keep volume modest, and get legal review before commercial reuse.
