I mean you KNOW the laws..

Quote from @Brandon Robertson: Yes, please come back and update us.This is a great example of why it's important to understand local law.

Landlord representation is all my law firm handles.

The first thing here would be the regulations and laws governing acquiring properties, managing properties and selling properties.

They moved in and within 24 hours sent the following letter (names have been changed): "Hi Dawn and Brian,Sindy and I are frustrated, disappointed, and really struggling with the idea of moving forward with the move into your home.We realize this is the first time you have rented a property to someone, and may not be aware of the responsibilities that landlords have, and want to inform you that there are habitability issues with the home that are quite literally against the law, pursuant to Colorado’s Warranty of Habitability Law, CRS §§ 38-12-501 et seq.

As I said earlier, this is strictly for investment purposes.The property does not have to be turnkey, if there is room for improvement that's of no concern as we both have the skill set to invest in whatever upgrades are required.

Since the laws are not for the owners and we are no longer there.

Or do I need to do it strictly as an investment property? 

Follow the lease and the laws in your state and start the eviction process.

Definitely want to do things right, sorry if it seemed like I was trying to skirt around the law 👍🏻
