Beyond augmenting from negligent use, I recommend upgrading to beefier anchors during install.  

It is good that you are conscious and thinking about steps to protect yourself, which to me tells me you probably wouldn't do anything so outwardly negligent that you find yourself in a lawsuit. 

My lease has a clause stating that the tenant will be responsible for costs if the plumbing issues are due to tenant’s negligence whether accidental or purposeful.Anyone who has dealt with situations like this with a tenant: your input is greatly appreciated.For further context: it’s a duplex and his unit is the second floor.

This is certainly not negligible to me, not when all of this was achieved on just $1.2M of private capital.

In response he referred to the lease section which talks about renewal and said the lease is already renewed also the rent is $200 (10%) lower than market rent or new lease we signed.I know this was a huge mess created because of my negligence and not giving him notice by deadline, but what can I do at this time?

Hi All,I own properties in Bay Area at CA.I recently got a letter from a lawyer claiming that I was negligent with maintaining the sidewalk, which resulted in his client trip and fall over it.There are no mention of what type of injury and damage.The letter show a half a foot section that is more than 1 inch in elevation.

Tax difference is negligible based on income being from rentals.  

@Berry Starnes - in the A-class properties/locations, I think there is negligible pain, and tenants in those locations are paying as though nothing happened.

As an experienced investor & Realtor in DC @Shannon Erickson, it seems unnecessary to hire a property manager for a Condo in DC as you should be capable of collecting your own rent and addressing any necessary repairs/needs the tenant may have which should be negligible in a condo. 

In the unsecured world inquiries are a big deal, way more important than your credit score actually, where a few inquiries have a negligible effect on your credit score when applying for a mortgage.
