I am worried about a good willed person costing me my home?

I live in a low income apartmentcomplex.  And yes management and the owners suck, but this is where I call home and I'm use to those idiots.

Anyways a nasty storm called a Deracho hit my building.   We were without power.  Because we are mostly old people and the disabled allot of help came to my building, including a person (I'm going to call him John).  He is the owner of a company (I'll call it Goodwill activities (yes it sounds like a different company, but so does his company).

Anyways at first he was just helping out my nieghbors.  He made videos severely over exaggerating what was going on in the building, but hey he's helping out.  But then he started hearing about how horrible management and the owners were.

Now he's trying to get rid of them and put himself in charge.  He claims he has lawyers ready for every apartment and our building is entitled to grants that he will get for us.  Im pretty sure its blowing smoke, like he's done in his videos.

However my worry is that when he didn't get his way he called the fire marshal to try to fine our building.  He keeps trying to call Hud, congress members, ect.

So I don't see how he or his company can just recieve our building.  So if I'm right, even if he wins and gets rid of our owners it would go to the city and then they most likely would sell it to the highest bidder.

Am I wrong
