I do think you have an idea worth exploring, but I wouldn't be surprised if there is some potential customers turned off by the look/feel of the industrial containers as opposed to traditional building so it may limit your customer base some.

-Customer serviceThe agents are always nice and courteous.

Tighten operations and make sure your customer service is above the competition.   

@Shu Zhu if you are comfortable lending the funds to your customer then go for it. 

The market here (like everywhere) now has retail customers paying size-ably inflated prices for properties.

You will pay much less per month for the software and the customer service is excellent. 

Also, if you're reading a good book and it mentions a U.S. law, or custom, maybe just make a mental note that it may be different near you....then ask other investors what their thoughts are....The networking will do more for you than you can imagine!!! 

I currently work I  hospitality which gives me a lot of insight in building positive, ongoing customer relationships, and proper negotiating and sales tactics.

I had a couple of HELOCs with them and could not be more disappointed in the way they treated me as a long long time customer with not insignificant assets with them.

It is easy to customize for your needs.
