Is buying a home inside of a TSP (thrift savings plan) possible?

[Darius Tracy]

I have been talking with my mother who has been working civil service for the government for over 20 years. On one of the podcasts I remember hearing how u could buy properties in a self directed IRA and was wondering if anyone had any experience doing so in a TSP (thrift savings plan) as this is her savings vehicle for her employment. Any advice is greatly appreciated. Thank you
