They have bots that look for every piece of furniture on the internet, create a listing for it, and then have it shipped if you buy it (often at a 2-3X markup). 

Quote from @Jim Crockett: Had a power couple go over to their ship despite my warning, they are young, we are not.

We have never shipped MLS data sheets.Below are some reasons why taking the next step with software, has not been successful for me.There is a lot of inaccurate information in the MLS.

But, like you say, that ship has sailed.

This is something I try to live by and teach my kids if I can - "A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.

I would like to build several (2 - 6) "shipping container" type homes for either short, mid or long term rental.

My plan is to add 2 - 6 shipping container type of small houses and an above ground pool at some point to make at least a section of the property short/mid term rentals.

It doesn't happen often at all.We run such a tight ship, we rarely have issues that need attention.

A mentor ship program is how most people do it.
