Seasoning for conforming Rate-And-Term (no cash out) refinance

[Ryan Johnston]

Are the terms/requirements/guidelines for a conventional/conforming Rate and Term refinance different than a cash-out refi?  Not asking about the differences in the product/concept, I've got that.  Also, not talking about portfolio lending.  Looking for answers that apply to conforming, conventional Fannie/Freddie loans.  Wondering about differences in underwriting guidelines between Rate and Term and cash-out.  Specifically:

Seasoning:  Specifically, if I have a hard money/private loan for 75% of ARV, can I do a Rate and Term refi to pay off that loan without 6-month seasoning period? Any seasoning at all? Shorter? Longer?

Refinancing out of an LLC:  In this post-continuity of obligation era, properties generally have to be held personally for six months to get a conventional refi where there is a mortgage involved (I've heard there are lenders who don't require this, but I have yet to find one who's not wanting to do a portfolio loan - send me your references if you've got one!)? Are the rules more relaxed for rate and term? Can you transfer title from the LLC to a personal name at close like you could in the good ol' days?

Thanks everyone! Looking forward to your ideas!
