I will throw it in there also that these have poor material quality (I am a civil engineer also), they overmix water into their concrete making the design -- even with a 3.0 safety factor -- useless, the concrete is very weak due to cement-water ratio not being accurate, just for the sake of workability/ease to work with concrete, to add to that, they will mix more aggregates and less cement (they don't have the accurate pre-mixed bags we have here), just because cement is expensive and aggregates are a fraction.  

Money will always be secondary to the safety and comfort of my tenants.My WHY is that I can positively impact a lot of lives.

And any safety concerns?  

They'll help with the knowledge you are lacking and you'll get to be involved in some deals with a safety net.

I asked them about the cost and they replied with one fly over every so often usually yields enough fines and back pay for the permits that it pays for that flight and they site that they care for the safety which negates the cost in their eyes.

Hey JasonI know you don't want to fasten it directly to the roof but for the safety of your tenants (especially if they're drinking) I think that is going to be your only option.

The equity in the property is your safety net if they default.

I agree late fees must be charged otherwise you will have a tenant that prioritizes rent behind everything that does charge a late payment.  

There is virtually nowhere else for fund managers, pensions, hedge funds, and private investors to put their money with a relative degree of safety offering any chance of appreciation or cash flow so they are basically forced to push these funds into the stock market when otherwise they would have not have.

Can it become a health and safety issue.
