Do you put a home inspection contingency in your offers?

Do you put a home inspection contingency in your offers?

I just switched from bank financing to all cash offers, then I rehab/rent/refinance. I like the idea of all cash for easy closing. 

I am still putting home inspection contingency in my offers which makes my offer inferior to a no contingency offer. 

I own 16 rentals and have walked through 250+ houses so I do have some experience. Should I bail on the home inspection contingency considering I am doing a pretty extensive rehab most times? Or is it perfectly acceptable and expected by the bank/owner.
