If you speak Spanish, just concentrate your search in the Spanish-speaking neighborhoods. Physically go there and look for signs posted on lampposts and in grocery stores. I can't imagine these low-end rentals would not take cash.
One thing, though -- if you see a room advertised for $600, don't be so certain the rent is going to be $600 for a couple. Think about it -- with more people using the bathroom and kitchen, why would the price be the same for an individual as well as a couple?
