Tax Advantage Program? AdvantageRN Co.

Has anyone negoiated with a Travel Nurse company that quotes a higher wage per hour but does not pay for housing or travel. They say the bottom line is better this way because only a portion of the hourly rate is taxed. This makes it difficult to determine the actual pay rate. I plan on requesting they give me a housing stipend per month, travel reinbersment amount and what my hourly rate is. Any thoughts????
