Tax, title, registration, dealer costs, shipping etc.If we go back 3-4 years in a less competitive market it wasn't uncommon for VA buyer to ask sellers to cover some of these, some of my clients even received enough closing costs assistance from the seller that they paid off some debt from the excess(btw you can only do this with the VA loan). 

Sadly, that's not uncommon. 

This isn't uncommon since you're values were so low ($50k). 

This is not uncommon but five days must be a target as no company will have 99% occupancy / if they do they are not charging enough in rent

@Vlad B.If these are c class or lower this is not uncommon

This is not uncommon for vacation rentals, but now cities are starting to enforce it for long-term rentals.

It's not uncommon for our clients to come out of a sale with no cash and still do a 1031 because they have accessed the cash through a refinance. 

Net worth in the millions from owning just a few rentals over a few years is not at all uncommon. 

Well said here by @Ben Scott and @Tracy Streich.I own a PM company in OKC and can say:  it's not at all uncommon to see managers driving a lot of revenue through maintenance (up to 40% of gross revenue according to some recent NARPM studies), but as to whether it is unethical or outright theft really comes down to:- Your Management Agreement with them- Their consistency in following advertised and agreed upon pricing policies- Acknowledgement of affiliated services.If there is anything else we can do to be of help here, let's be chatty in this thread and help @Derek Branch have a winning path forward

Also, it is not uncommon for Boards to take actions they have no legal authority for.
