No matter where you go remember you can fight the taxes. 

Most will go to court for you to fight evictions and to get rent or damages.

Check state laws as to collections.Obviously the optionee is not a successful attorney, probably a loser with a degree, so I'd go full bore from all directions, beginning with an eviction for possession and fight the option another time, these are two different matters.

Your positive energy and the willingness to fight those few months is the difference between "I should" and "I must".I love the fact that you bough the property right.  

In the end we found the best terms and have banks fighting over us. 

That way the listing agent is able to take the full commission from the bank and will be more willing to fight the bank for the lower price that you want.For example, normally commission is split between the listing agent and selling agent.If the house sells for 100k, and the commission of 6% is split between buyer and seller, here is how the numbers play out:Cost to buyer: 100k.Listing agent 3K, buyer broker 3KIf you have your buyer broker negotiate the deal for a sale price of 75K, with you paying the buyer broker 5K from your pocket, here are the numbers:Cost to buyer: 80K (75k purchase price + 5K commission), listing agent $4,500(6% of 75K), Buyer Broker 5KNet result is listing broker has more incentive to fight for your lower price.

They automatically assumed I would be living in the biggest vacant unit, although I didn't fight them because it didn't impact qualification.

@Hattie Dizmond  all of our stuff is sale to Owner Occ and we have been in knock down drag out fights with appraisers and we lose.We are exiting the 200k and under product..

If you are in a competitive market, then you will have to fight off guys who will pay much more than what would make sense to a normal person just so they get the deal.

Two choices, stick to the agreement, go to court and fight it and possibly lose getting slapped and having to pay the estate, or the other choice, pay the amount demanded.I selected the latter cutting a check with an assignment of that interest.After that, I started brushing up on security laws.
