How we merge listings and what the photos confirm
RemRent brings rental listings from Brazil's major portals into one search. Every listing here links back to the original ad.
This page explains what happens between the portal and the card you see.
One home, one card
The same home is often advertised on several portals, sometimes by different agents. We compare the photos of the ads, not the title or the text. Two ads whose photos show the same rooms are joined into one card.
The card keeps a link to every ad it was built from. A photo repeated within one card is shown once.
What the photos confirm
A vision model looks at the photos and records what is visible: furniture and kitchen appliances, the condition of the finishes, the flooring, the view.
Whether a home counts as furnished follows a fixed rule: a bed or a sofa, a fridge and a stove, and somewhere to sit, eat or work. Only what a photo can show is recorded.
Bedroom and bathroom counts, floor area, price and contract terms come from the ad, never from the photos.
What comes from the ad text
Some terms come only from the ad text: no guarantor needed, pets allowed, what the price includes, covered parking. We show them as the advertiser's claims. We do not check them.
Where a card has a summary, it is RemRent's own text, written from what the photos show and what the ad says. It is not the original text. The original is behind the portal link.
Five languages
Card titles, and the summary where a card has one, are written separately in Portuguese, English, Spanish, Ukrainian and Russian, from the same facts.
The site's own texts and the articles are written from scratch in each language, not translated word for word, and go through two independent reviews per language.
When an ad disappears
We keep going back to the portals. When an ad is gone from its portal, the card loses that source.
When the last source is gone, the card leaves the search and its page says the listing is no longer available.
How we compare prices
We compare a home's price with similar listings on RemRent: apartments with apartments and houses with houses, of a similar size and with a similar number of bedrooms, in the same neighborhood or the ones around it. It is a comparison of advertised prices, not an appraisal of the home.
When there aren't enough similar homes nearby for a reliable comparison, we widen it step by step: first to neighborhoods farther out, then to homes of other sizes and with one bedroom more or fewer, and if that is still not enough, to the whole city, as a last resort including homes of other types and bedroom counts. Whenever homes of other sizes are included, their prices are adjusted to the size of the listing being rated. “How we worked this out” shows how wide the comparison went. Listings that don't state a neighborhood, a bedroom count or a size get no rating: without them we can't pick similar homes.
We usually compare rent plus the condomínio, the building fee, without the IPTU property tax. When a listing quotes condomínio and IPTU together, we compare rent plus that combined amount with the same kind of total for similar homes. When the listing itself or too many of the similar listings leave out the condomínio, we compare rent alone and say so under “How we worked this out”.
There are three ratings: good price, typical price and above typical. A card shows “Good price” only when we found enough similar homes that share the features that matter.
We rerun the comparison every night; “How we worked this out” shows the date it was last computed.
No advertiser can pay for a rating or sway it.
What we do not do
We do not visit the homes, and we do not check the advertiser, the price or the availability. The price on a card is the one advertised at the source.
The same ads are free on the portals. What we charge for is the direct link and the work described on this page.
