Budget Breakdown: Two Travel Therapists Build a Tiny Home-on-Wheels for $24K

Already swamped with student loans, Saul and Trysh Martinez spent $24,350 and almost an entire year building their own 250-square-foot home-on-wheels in San Diego, California, as an alternative to keeping up with a mortgage or paying rent. "The financial reasons were reinforced by our plans to be travel rehab therapists and work for hospitals all over the country," says Trysh, who works as a speech-language pathologist while Saul works as an occupational therapist.
