Seems to me this is a breach of the lease and potentially forfeiting the deposit but I would check with a local attorney for verification.

i dont wholesale nor consider wholesaler offers but perhaps someday will. i just don't understand what's in it for the seller to waste even more time in contract with someone thats not trying to get financing, but with someone thats trying to find another buyer to enter into a subcontract with that will in turn start trying to get financing within another contingency window; thus the seller accepting a wholesaler offer is entering into a potentially double contingency unless the buyer found by the wholesaler is an investor who is actually cash buyer.do wholesellers at least forfeit some of their deposit to the seller if/when their contingency period expires unfulfilled?

Typically a deposit is forfeited to cover missed payments if they were to break a lease early.

Likewise, in a reverse exchange there is the risk that after assuming hard money loans on the new park, I don't successfully finance the new park with a bank loan, in which case I would likely forfeit the park or sell at a loss.I like the idea of selling the rentals with more or less a variable closing date to coordinate them better.
