You nailed it with this answer! 

Wayne nailed it.

@CK Hwang @Jeff S  hit the nail on the head.I would add in response to your questions, being someone who brokers hard money loans and deals with lenders and investors, that other qualities besides rate and terms is your comfortability with the lender or their representative/broker and them actually following through when you need them to, no surprises at funding, etc. 

Now, as to wholesaling, gurus simply mislead or aren't aware of the risks, as usually shown there can be significant risks, ask the wholesaler BP member in FL who posted about getting nailed about 6 weeks ago!

@Mark Gibbs and @Joe Mclain have hit the nail on the head.  

Pretty much hit the nail on the head unless you'd like to sit back and let someone handle your portfolio from start to finish. 

Not limited to- -heavily stained carpet-holes in the wall due to large nails, improperly hung items, poor drilling, etc.

"To a man with a hammer everything looks like a nail."

I believe I cleaned all living spaces as well as one could, minus normal wear (nail/tack holes in walls, nicks, light staining etc).- I cleaned kitchen and bathroom NOT QUITE AS THOROUGHLY AS I WOULD'VE LIKED.

Work on the process of finding the deal, get it nailed down start looking for the next.
