Question: how do i apply for a loan through tsp? 

Answer: If you're talking about the Thrift Savings Plan, just go to their site (TSP.gov) and click on Loans.  Follow directions from there.\nI just got a loan from them and it's faster than ever.  Applied last Monday, got my check on Saturday.  Just be sure to submit your application electronically, rather than mailing it hardcopy.
