Buying 180k home, Have 180k. Possible to buy with no income?

[Bryan Tasumi]

I am buying a 180k home out-of-state. I have 180k in cash and in investments but temporarily will have no income in the state I will be buying the home in. Is it possible to buy a home and get a conventional mortgage with good interest rates (3.85%) using the money as a collateral while only putting 20% down? What are some ways I can purchase this with only 20% down but no job lined up in the state (Texas)? I have am self-employed currently making over 70k a year.
