I own a business that builds modern, prefab tiny homes (or cabins depending on how you look at it), and I am looking for a market where I could set up a few of these to use as model homes, available as a STR.

What I did was a Business Line of Credit on all of the properties.

It is always recommended to do it using LLC but not all types you will qualify if you don't have business with the lender or you don't have experience.Feel free to reach out and we can setup a call, I am working with multiple clients that are doing similar things in DFW.

I thought if you rent < 7 days avg it was a business instead of a rental.

Anyone lending on a build is going to run a title search on the land and see the lien. 

For MF you should treat it like a business and increase NOI through opex discipline or rent growth factors.

And already have a LLC set up for my Real Estate Sales business.

You’ll be lucky to get this as a newbie.These total $188k and don’t include property & title insurance, closing costs, property taxes, utilities, staging, and all other misc. costs

We looked into several projects and eventually, I concluded that there is no real reason for me to reinvent my business, other than "just because".

I’m pretty sure their business is organized to make them judgement proof in case of a lawsuit. .
