You get regular monthly payments that you can roll over again and again.

In terms of the funding options for your next deal:1) if you have IRA (Roth or Rollover) consider SDIRA.2) if you have your own business, consider solo401k. you might be able to move Rollover IRA funds into it. also, a better option than #1 above from a taxes perspective3) partner up with money partner4) look into leveraging your personal life insurance policy as a loan (if you don't have one, go get it)5) you can borrow against your 401k at work up to $50k. you pay interest and all back to yourself

I know I could roll over to other 0% CCs as necessary bc it's a strategy I implement now for myself personally.

Try to get your credit score above 700.If you find the right deal, you can roll over closing cost into the loan.

You can clarify when and how to execute any rollover options by contacting TSP directly.

I would have to roll over my 401K into my IRA which would give me a total of $350K in that account.I have Another IRA with $70K and the ability to get a loan against my home of $150K.But might be easier to get a partner on the deal.Thinking I probably could use someone with experience in evaluating the deal. 

Also can I still contribute to my SEP-IRA if I rollover part of my funds to an SD IRA\Solo401? 

He would be looking to just roll over around $300,000 and let that stand as our down payment on the $600,000 loan.

@David M.As @Chris Tabanico indicated, a self-directed 401(k) is still a 401(k) style retirement plan, just with broader investment choices.When you retire from service, you will have the ability to rollover all or part of your TSP. 

I'm looking for a recommendation of a self-directed IRA and/or HSA custodian to roll over 401k funds from a previous employer.
