proper installation?

Anyway- you will always get the home with a proper eviction.

Cash is king and you might be able to build with out following the proper guidelines, but buyers will have trouble with financing like FHA when you try to sell. 

If installed properly, the only maintenance should be cleaning and recaulking the surround to tub joint, but that is true with a tile surround as well.

This could include: Personally securing the mortgage loanPersonally committing a tort or crimeCommingling accounts, other other finances, or assetsFailure to properly segregate each entity including yourselfNow I don't know your full story, but based on the size of your LLCs and the way you described your money handling, you may have already created a liability for yourself.Hope this helps!

The issues you will be faced with are having the proper engineering and having your container inspected during the build process just as you would with normal construction even if it is not at its final destination.  

Once your figure out how to vet the tenants properly, you will have very little issues, and MUCH more cash flow.

For example, I received a call from an investor asking us to help walk him thru a hearing for a large fine he received for not having a rental property properly registered.  

One should still be careful in maintaining the heat in an occupied or vacant property or properly winterizing a vacant property though.

We don't have a GC for the job, but you just need to make sure all the proper permits are being pulled for the work being done.
