It's nothing you can control.

Los Angeles has one of the strictest rent control laws and ordinances in the country.

Does anyone have a Colorado law reference that details the landlord's financial liabilities if a rental property becomes uninhabitable due to something outside of the normal Landlord or tenant's control (i.e. natural or human caused  disaster, system failure like sewer or city water breaks etc.?).

We have increased management/cleaning systems and paid for monthly pest treatment to stop this from happening again.

It has been a really good business but we maintain control while renters are on the boats and can shut down anything that add too much excessive liability. 

Condo associations here are notorious for outrageous pricing and control.

This will make it much easier to attain loans through an LLC or even personally once you have control over the units.

And to tag onto what Tom said...a property in DC owned by an LLC is automatically subject to rent control.

Heating, A/C. plumbing, pest problems, appliance failures. 

If you can't keep control of your personal finances, you are highly unlikely to succeed in real estate investing.
