Meaning of The Pink Houseappears in Two Dreamers

In Two Dreamers, Luis locates a pink house for sale about two blocks from where he lives. He mistakenly assumes the house must cost about thirty thousand dollars. In fact, it is listed at forty-three thousand. The realtor notes that the sellers might accept a lowered price of forty-one thousand and five hundred dollars. Luis, via Hector, argues the house is not worth much more than thirty thousand dollars because the pink stucco is cracked. Needless to say, he does not make much headway with the realtor while pursuing this line of reasoning.
