They need to put them into the correct GL code (or the right property if they manage more than one).   

Besides the architecture/construction considerations (building code, finding a contractor that know how to work with containers, etc), does anyone has any experience with these, specifically in terms of financing and insurance? 

Throughout this time, I have been thinking a lot and researching about whether it would make sense to continue spending the time renovating, or if I should buy refurbished, or if I should even look to purchase new.For those who are experienced in this space, I was wondering if anyone has ever done a financial case study to see if manually building a HUD code approved mobile home (via Home Depot materials) could potentially be cheaper than purchasing new?  

Overall this gives me data on 358 local zip codes that allow me to population trends over 10 years, home price trends over 20 years, and rental information for different configurations.

If you must do it, follow strict code. 

 enter zip code and 'maid service' into google.

The garage apartments in the back are excellent for singles or students because they're smaller and usually a little bit less on the rent cost. if you'd like to look up some examples of those setups here in Houston and you're using the BP insights or other data tools, look up zip code 77004, 77005, and 7700 6.

In the past I have invested strictly in residential properties (1-4 units), I have closed on more than 20 rehab/rental/flip properties, and have worked as a commercial analyst for a large multinational commercial real estate management firm. 

Great idea - One big problem is local government.In Portland, change of use is near impossible even in zonings that allow you to back fit residential.They write those codes and keep adding to them and really don't like people not following them no matter how good/useful an idea you have.

I checked the zoning codes but really didn't understand it that much..
