My experience is that with a home warranty, quality tenants and newer homes my expenses are negligible.

Basically, what is negligence?

If that's the case then per the contract they can only come after the earnest money.Of course if you had gross negligence,fraud,criminal activity etc. they can still come after you.If you tied up a property and then didn't perform the seller is being impacted in a negative way.Again with a wholesaler this is why non-refundable earnest money would be required if it was my client.If not we simply wait for another buyer or can kick them out of the contract and accept another offer from another buyer at any time.That way you have the wholesaler working on the long shot at the same time as pursuing other buyers.

Granted it has slightly more ongoing maintenance than a surround but negligable.

Governmental police actions (police powers as to  RE, not the cops raiding the place) work can be stopped for inspections, stop work orders can be given, building permit snafus, all may be beyond the contractor's responsibility, then again, a contractor that screws up can cause a stop work order, so define it "police actions not arising from contractor's negligence or failing to remain in compliance....." 

The Trustee and his successor as Trustee shall not be required to give a bond, and each Trustee shall be liable only for his own acts and then only as a result of his own gross negligence or bad faith.9.

If so, then I would go to the TREC and complain that their negligence is holding up the deal.When did the title co. decide not to release funds until they get the letter from the Broker?

You'll need to prove a professional negligence on the part of the appraiser and non-performance would not qualify for that. 

I am filing a complaint with the Maryland Real Estate Commission, hiring an attorney to take over the eviction, and will be suing you for losses incurred due to your negligence." 

As for the responsibility, what should be said in that part is if a tenant's own negligence somehow caused the break-in (i.e. like if a tenant left his door unlocked and wide open) - I can change that.
