The story is not yet finished, just called someone who knows these guys, and here is the story:
they rent a building for 1 year, pay 12 checks, for let us say 10,000 QR /month/aprt , then they re-rent it again for 6,500 QR/month/apt one year in advance.

The next step is not to pay the rent to the owner, so the tenants will have a problem with the owner, and it will end up with the tenants out of apartment.

True story, ....
