Cash offers using hard money

[Mario Cuartas]

I have heard some investors say that when using hard money, they make all cash offers, however they are not all cash because they are in fact using hard money financing. My realtor is telling me that we must include in the contract that it is contingent on financing because we are using hard money. This weakens our offer compared to someone claiming to have all cash.

If I am using hard money, am I legally allowed to say all cash on the offer and not make it contingent on financing? If so, and they ask for proof of funds, technically the cash is not in my bank account, so how would they view the pre-approval letter from the lender?
