This requires more money down and "skin in the game".

They want to know if it's borrowed because they want you to have some skin in the game (10-30% usually).If you're new, I'd focus my first deal to be a little smaller and not be so leveraged. 

And now you and your partner have skin in the game. 

There's a reason wholesalers get a bad reputation - and it's not because they are making a profit without having skin in the game or don't have a license - it's usually because they move crappy deals, or they hang their clients out to dry when the deal goes bad, or they sell to people who really shouldn't be getting involved in the deal because they are not capable of handling the deal.Also - there's not one single definition of what "wholesaling" is.  

If you don't have a thick skin, not for you.    

Again, other might feel differently here.b) Skin in the game: as a conservative investor, I understand that the dirty secret of industries that the waterfall compensation is in the line with me and incentivizes sponsors to take more risk.

I ask because I'm a little uncomfortable that the "expert" has no real skin in the game and if it went sideways they aren't out anything but time. 

Looking for a RE attorney/title attorney, GC, and/or realtor that is willing to put some skin in the game and be active with me in searching for and closing deals.

Who and why is someone "potentially" letting you in with no skin in the game?

Not saying it's not possible, but this is likely the hangup. buying cash and then cash-out refi is easy and done all day, even with commercial loans, but likely all will want you to carry some liability in some form (skin in the game) that said, I'm just one lender I can't speak for all of them
