why does esparanza ask about the house

Esperanza visits Elenita the card reader to have her future read, but her most important question is 'will ever have a house of her own." After reading the cards, Elenita tells Esperanza that her house is full of heart, and that she will light at candle for her that she will have a new house full of heart. She then blesses her.

She asks because she has certain aspirations and requirements for the home she dreams of, not a home like her parent's.
