I see mobile homes, and steel garages, and large steel girder buildings, but nothing that is something i can put together and finish myself, with floor joists like this one https://www.alibaba.com/produc... 

If that well made them sick ( which is very easy to do with contaminated water) having owned a Mobile home park on private water system myself.. you have a lot of liability here..  

Currently, we have 4 mobile homes and land to add more.

The website is mobile-friendly, so they've decided to stick with that rather than try to operate two different platforms. 

More people probably looking in the cheaper/median priced areas as well with inflation kind of hitting peoples wallets more the last year or two.I think updating the units and being more aggressive on price is really all you can do since we obviously aren't in control of the economic factors.

Consider all of your life dimensions and what can you wallet and your time afford. 

However, I just found out Easy Self Storage started to sell their own access hardware, and then it released a new feature on their software/website that you can see gate access activities/log live and can even open/close the gate remotely simply through the website (even on your mobile!).

I have a deal in my hands of 7 mobile homes all on separate .25 acre lots and all rented out to long term tenants.

This would be similar to a Mobile Home Park, minus the mobile homes. 

Mobiles and land, fall into different categories.
