Holding my cash for future RE deals is my main objective, and I'm not dumping my reserves into a slot machine. 

Portfolio lenders and commercial lenders that do no have a seasoning requirement nor a max number of loans, although their terms are not as desirable as Fannie / Freddie.Here's my question: if the investor has not maxed out his Fannie / Freddie loan slots, is there any disadvantage to first dealing with a portfolio lender or commercial lender and conducting many BRRRRs in a short amount of time, taking that approach as far as you can, and then moving on to conventional Fannie / Freddie loans?

I just know there will be a mostly consistent 9 hour time slot where I may not be available on. 

While all 8 slots are currently filled, one of the selected individual may not be be able to attend.
