I think it's better to just keep properties together under one LLC if you are a small operation - even though there is always risk the amount you end up spending and time spent on overhead of keeping separate books, checking accounts, etc adds up fast.  

Make sure they are operating ethically.

Some of my lenders use the operative word private for a reason.

The options available depend on the size of the park, the location of the park, the value of the park, and the experience of the operator. 

Unless you have a partner just operate as a sole proprietor.

It was summer the sun was shinning it was fungot the locals tour of the tar sands operations pretty amazing stuff.I wonder whats happening in Frack ing North Dakota.there was a bunch of guys selling hotel rooms to unsuspecting Aussies 3 years ago promising 45% returns.. of course the Aussies not knowing any better jumped on board.

Many of the windows were missing screens and the windows difficult to operate (or not at all) when I purchased the property.  

This can be done through an operating agreement, within your articles of incorporation, or another vehicle as advised by your attorney.

If I were smart I would have held on to even the lowest rent properties I've sold in the past 15 years, as long as they were operational.

You would also likely be better off shutting down the LLCs and operate as a SP which will save you money longterm.
