Go through the formal eviction process, hire an eviction attorney.

We were two weeks from closing, and I received a call from our attorney stating that the title came back incorrectly.  

You'll probably get some good ideas here, but I'd suggest talking to a real estate attorney soon and maybe run some of these ideas by them.

Also, I recommend Harry Borders as an attorney and for closings.

If so make they have their earnest money held by the attorney and not the agents broker.

A good local real estate attorney, is just a phone call away too.

I wonder if Mitch was able to get his refi done before a NOD was filed and or late payments were put on the orginal sellers credit report.. this is the real risk to the seller if they value their fico score at all.. on some of this stuff the sellers credit is already trashed and they dont care.. but if folks buy from someone that does care holy cow when they get the NOD notice its right to the attorney.. 

You got some solid advice above check with your lender and get in contact with an attorney like @Bob Floss II who can help setup the OA.Assuming there is no pushback from your lender, you should be able to do a quit claim deed to retitle. 

Does anyone know of a good resource for this type of rental or a good contract attorney?

Most reputable HMLs will not charge anything until you are sitting at the closing table and all fees will be listed on the HUD-1 closing document.And of course, what are the points, interest, and attorney/document/admin fees for the loan?
