This property gives me significant income, so losing it would be an extreme loss.

Coffee shops, fast food, subscriptions, even consider what groceries you buy. 

I know it's a long shot, but I'm currently having lawyers review the signed subscription documents to see if there's any way to minimize the losses here. 

That still has the 50% use requirement, but can be used to create a tax loss. 

Recently decided, to invest in a mobile home park but sold at a loss.

Not enough information here to answer this question accurately.Is the home a total loss? 

I walked to the house and met a man who says he was cleaning out due to the loss of their mother in some few weeks back.The guy told me she is  left with 12 years mortgage on the property to pay the bank.

There were people out and about smiling and offering free food to other residents.Through the ups and downs, we continue to believe in the project and the area.

Why can't I go into whole foods and steal their food without getting the police called on me?

It doesn't cover any loss of income due to your rental being repaired.
