When you're that wrong about Tricare costs, I see no need to engage you on a discussion of the Vegas real estate market. A quick search on realtor.com will find more than 300 3+/2+ houses in Summerlin for under $300K; I suppose you find the only 'acceptable' area of the country to be rural Mississippi.
