Premise: We might also interview selected low-income families with regard to their experience in seeking housing or we might, as participant-observers, pose as low-income applicants and report our own experiences in finding housing for families of different sizes and within different payment ranges (judgmental, numerical, and nonnumerical).
Hypothesis: Interviewing low-income families might provide first hand experiences in seeking housing that we might not otherwise have access to.
