I would not recommend using any of the clauses as describe above for one reason. It will not make your offer appear as being strong and you will lose deals. I would not worry about it.
A 'wholesale' deal is anything below 70% of market value. If you are buying right, it should not be hard to find a 'wholesale buyer'. Start building your 'wholesale buyers' list. This is very easy to do. Start looking in the newspapers for all the WeBuyHouses Ads and start contacting all the investors in their. You could also look on the internet. Just do a google search with this term: "WE BUY HOUSES".
In terms of disclosing to the seller or realtor that you are 'wholesaling' the property, you dont want to do this. Simply tell them that you are going to be closing in your partners name. One other thing you can do is put in your contract "Vesting to be determined at closing". If the agent gives you a hard time, just tell them that you may be closing in a Land Trust or your Corporation or even you private name.
In terms of backing out. You can always back out! Your home-inspector finds something wrong with the property, you have trouble getting financing, decided you dont like the neighborhood, etc.. You just may forfeit your deposit. Like I said earlier though, if you are buying right, there should not be a problem.
