@David Pierce thanks for the information and lengthy write up.

At least you can terminate in 60 days on a non-paying tenant and avoid a formal, lengthy, and expensive eviction.What towns are you in?

Do you know how lengthy the process is and the cost?

The fastest option would be to figure out some arrangement for her to leave without having to go through the entire process since it can be a little lengthy.  

Thank you for your input as well, I hope I can take it back with a clean, unclouded title vs. a lengthy foreclosure process as I plan to rehab it and sell it within a few months. 

Since this is your first property, I would recommend you start with a single family home instead of a duplex to minimize the scope of the rehab so you can learn the process a bit easier than a larger, more lengthy rehab.

You're not alone, contracts are lengthy and complicated and there is a lot to consider, and every single person in this business has been where you are right now.There are numerous clauses, or contingencies they are also called, in all real estate contracts.

It was a lengthy and cumbersome process and most loans were not modified. 

Also John, nothing is recorded until the property is "paid-in-full", ...thus avoiding possible expensive legal and lengthy actions (I.e., "lis-pendens", foreclosures, etc.).

I apologize in advanced for the lengthy post, but I'm going to try to be as detailed as possible, so here we go...I currently has a property under contract that I have been prepared to close on for my first BRRRR but have run into an issue.
