The way I read the law, it seems like a mobile home is considered a vehicle and you need to have an automobile dealer license to buy and sell mobile homes here in Florida.

Since you're not making money on the cashflow, you will need to look to make money on some other piece (appreciation, tax benefits, or loan amortization; betting on appreciation is a gamble, and tax benefits aren't really a moneymaking vehicle [more just a money saving vehicle], so you're pretty much just left with trying to amortize the biggest loan possible).Does that all make sense?

The second option would be to use a vehicle like a Series LLC.

If you can't find a data tag, you might be able to find the serial number on one of the first two frame rails, underneath the home, in the front.

This is a very common concern with investors; an LLC may not be the best vehicle based on property utilization.

Is there no vehicle for “bonding off the mechanics lien” there, as there is in most places.  

Very familiar with running the numbers on vehicles but still getting into it with real estate.

But there are plenty that are PAVED with guard rails and maintained - not one lane gravel that you have to maintain.So again, if the main use is for your personal use and you just want to try and make a few extra bucks great.  

Cutting in some zig zags to the driveway to allow non 4 wheel drive vehicles?

It is a remote rental with access to a rental vehicle.
