Films like these really aren't supposed to be dissected, although I often do. They are primarily meant to stir discussion and bring attention to certain societal issues or to bring about change. I thougt this film was good but suffered from unrealistic Nash family story in terms of the homeless unemployed entitled granny turning down a nice home because.her hard working son worked for someone she didn't agree with. Right. Never in the history of man has someone walked away from a bought home because of that. Prove me wrong and I will post a Youtube video of myself eating THREE HATS.

Ya kindof a huge plot hole

I just saw the film. I believe they are saying in it that Frank Green had failed to receive proper notification of the foreclosure proceeding. NOT that he had been paying on the mortgage.
My guess is that despite the confession, this would be confusing and hard to prove.
Also: Frank Greene was stealing electricity and water.why? he had to be DESTITUTE to do this. It is possible the filmmakers are not Americans and have no idea how American homeownership works. Perhaps they think the BANK supplies you with electric and water? hahaha! that is not remotely true.
I actually lived in Orlando for years, so I KNOW FOR A FACT that you must pay for your water, electric, gas (if you have it) and other utilities (even your trash pick up) SEPARATELY. It is not on your mortgage bill. The utilities all bill you separately.
To get "turned off" by water and gas would require you miss payments ENTIRELY for at least six months. So Frank Greene (and his wife! what is she, a moron?) seem to think they can not just live rent free for years, but also get free water and electric? By STEALING? and this is HIS RIGHT? He also tries to kill innocent people and police officers! you can't justify that because of a fraudulent document in court! You can sue, but you won't get off the hook for armed assault on the police! Frank is going away for a long, long time and won't have to worry about rent. Not to mention how he has screwed up his kids, who will now be in a motel or homeless.
Watching this movie would actually make people stupider. The sad thing is the foreclosure crisis was as genuine big deal and the Federal Government botched their job to protect us, and yet this film says NOTHING about what REALLY happened. It is just a terrible waste of celluloid.

Good point. I didn't understand what Nash did at the end would have done to help the guy out and keep his house? Apparently that's why he did it but guess what? You haven't been paying for two years on your mortgage and you have to steal electricity to get by you are going to lose your house anyway. Only hope is a loan modification. I've been there. Some technicality isn't going to allow you to stay in a house you can't pay formay give you a brief reprieve but that's about it. I lost a house during the crisis. And I just hated the way these people who did not pay on what they owed just ignored reality and thought that telling the cops "it's just a mistake our lawyer is on the phone sorry for your trouble.." Yeah, that doesn't work.
I absolutely hated Laura Dern's character.

Carver was indeed that cool and calculated type. Even if cops/FBI in suits arrest him I bet he could get a deal by implicating others as is the norm in movies. Little fish help DAs catch bigger fish and are let off the hook.
Nash was little fish, Carver was bigger but he was working with crooked people like county commissioner Link and the grey bearded man, Freeman, working for Vesic Investment Group. Elected official, commissioner Link and grey-beard forge documents for Carver. He has leverage. I bet Carver would have worked the system and gotten off the hook in movie universe justice system.
Another thing that bugged me was the Greene family eviction. Frank Greene is so broke he can't pay for electricity and water. He's apparently been unemployed for two years. Surely he's behind on his mortgage payments. Clearly he's going to get evicted and bank will take the house. Now we find out there's a technicality that supposedly stops or postpones the eviction? How can that be? In movie/TV justice systems we a taught to hate technicalities. Usually technicalities let murderers free because of typos in warrants or such things.
What is a proof of publication? It had something to do with his mortgage being sold from the lending bank to another, then again and again to be packaged as an MBS. Why does it matter?
Finally in the armed stand-off Frank Greene says something about cancelled cheques. So he was paying off his mortgage? That would be easy to prove. With what money was he paying it?
The film would have been a lot better with a more cynical ending.

The way Rick Carver explains it in the film is that if one homeowner "won" and kept his home, then many other homeowners would follow suit. So they would lose their deal with Vesco because Vesco probably wouldn't want to be dragged through the court system.
