In many jurisdictions it is a violation of privacy law (and, as a minimum would require the consent of the tenant).  

That requires that consent must be given by the non-performing actor, the seller must agree to allowing another to take the place of the buyer.

Doesn't mean direct management of the manager, you do need to keep your distance and not become "active" in the management, but to set policy and stay on top of the books.Speaking of your due diligence, Jarrod makes an excellent point concerning additional contributions by members that can dilute your interest, this should be addressed in the OpA and may be limited requiring consent of other members, or to equal contributions.

You can place that provision in the contract for purchase and sale.For earnest money it is key that the language is written in a away that the EM - IS NOT interpleaded into a court of law if both parties cannot agree.If the buyer can demonstrate that the seller is in default or that the buyer has the right to cancel then the sellers consent will not be needed.It's important to have that in there because I have seen sellers or attorneys do a ransom where they say your 50,000 earnest money we will dispute and then title will have to interplead into court.
