Did he file it recently or a long time ago? 

So normally, if the old property was in an LLC the new property needs to be in the same LLC.However, if that LLC only has one member and it chooses to be taxed as a sole proprietor then it doesn't file a tax return. 

A bankruptcy filing doesn’t negate a foreclosure...it only stalls it for a couple of months.If someone buys at a foreclosure auction Without knowing they are buying from a second mtg foreclosure, and are at risk of the first mortgage foreclosing, they have no business buying through a Legal Action against someone else.....they should stick to safe, normal transactions.And so that everyone knows....when you bid online at any FL foreclosure auctions, you have to acknowledge several warnings that these properties may not have clear title, there are risks involved and that you should consult an attorney if you don’t know what you’re doing.

Do you have to file and pay State taxes in states where there is a State tax if you are buying and selling in a Nevada LLC?

Unfortunately had to file an auto claim with Geico when another car hit me and the whole process was simple with no games.  

I would file even if there is no activity. 

We file Jointly.

Perhaps I'm wrong, and I'm not insisting but from what my accountant said it's a net wash as I'm filing personal.

Also your local building department may have homeowner nights where you can go and ask any questions you have regarding the process of filing, permits, construction process, etc. for free.As Zackary also mentioned, YOUTUBE is an amazing resource for learning the ins and outs of basically any home renovation project.

There are no penalties as long as you do this before the tax filing deadline.
