What insurance should I be getting as a landlord?

[Paul McCoy]

I've been actively managing my own properties for the past 5 years, and recently I've been considering taking on the management for a few other investors in the Denver area.  I'm wondering what kinds of insurance you would recommend for someone who manages their own properties, but is now taking on others' properties?

I've read about General Liability, Professional Liability (E&O) insurance, and "Landlord" insurance for owners who rent their own homes. I have a couple specific questions that I'd love any insights you might have on!
1. For owners managing their own properties: do you have Landlord insurance beyond your regular home insurance policy?  Why or why not?

2. For those managing properties for others: Do you have General Liability and Professional Liability yourselves?    If so, how much do you pay and for how much coverage?  Was there a certain number of properties you got under management before you got it?  

Let me know what you think I would be curious to know, my goal is to be responsible of course, but not excessive and not sure where that line is.

Could you clarify what you mean on #1?

Regarding #2 you should definitely get insurance classified as a property management company.  General liability and professional/errors & omissions.
