When translated to English, "apartamentos en renta" means "apartments for rent." "Apartamentos en renta" is a Spanish phrase that can be translated to any other language.
The Spanish word "renta" can translate to either "income" or "rent" in English, but "rent" is the word that works best for this specific phrase. It is also considered a proper translation to English from Spanish by saying "apartments in revenue," since "renta" can translate to just more than "rent." Either phrase is considered proper in both the English and the Spanish languages. If one wanted to add the phrase "I am looking for," "estoy buscando" would be added to the beginning of the Spanish phrase to make the sentence "I'm looking for apartments for rent."
