And causes you to have to pay the tax on unrecaptured depreciation.  

What damage and other things should I look for to consider should I decide to make an offer?

You also have the time and brain damage of dealing with them.

Some of the issues that would be addressed are: Death or Serious Disability of a Partner/Member;Withdrawal;Assignment of Interest;Failure to Contribute Subsequent Capital Contributions;Material Breach of the Agreement; ETC....Any potential issues that could arise during the operation of your business, should be talked about before the creation of any type of entity; then once discussed, put down in writing in the agreement so each person agrees to the outcome BEFORE it even happens.In the event that a Partner/Member violates one of the provisions of the agreement, they then become personally liable for any damages caused by such breach.
