Protection of rental units from damage

[Ayo O.]

I was wondering what everyone else is doing to protect their rental units from damages by tenants.I typically collect 1 month as security deposit and require tenants to carry rental insurance policy( which most don't keep current)I also have landlord insurance policy however, I think the security deposit may not be enough to cover most damage cost. Is there any insurance policy that specifically insures against damage to rental units. TIA
