None of this is rocket science and you don't need a finance degree!

There was a fine and cost to register before I could sue.

I went to school and got a finance degree.

I would recommend going over your contract with a fine tooth comb.

Combine both their knowledge to come to a final conclusion.

As a final thought, I'd advise finding out as much information as possible on LLC's and asset protection strategies and structures before talking to an attorney about this issue.  

With the time and effort to build in dense area there is a fine line between being feasible or a money pit.  

I recommend talking to a lawyer.We charge them a fine, and then the dog has to be off property.If they don't pay the fine by the next round of evictions we evict them.The tenant knows the rules and is actively trying to violate the rules.If you let this slide, other tenants will start to do the same.

All I can suggest @Anthony Lewis is to look through your lending documents with a fine tooth comb and maybe the answers you are looking for are in there.

And being a fine, upstanding young man in love, I offered to renovate that apartment for her.
