Program for cash-out refi after 30 days?

[Sam T.]

I remember hearing on a couple episodes of the BP Podcast about some program (I think it was something government-sponsored if I remember correctly) where you can cash-out refi after just 30 days on a rental, with the only "catch" being that you can't cash-out/get a loan for more than the total amount you've put into it.

I can't remember the name of this program to save my life, but I want to look into it further for a rental I'm planning to buy that I don't want to wait 6 months of seasoning to refi. 

Any help please? Someone know what program I'm trying to think of?
