My landlord handed me a letter saying I have to carry renters insurance with 100k liability and I have honestly never had a policy in my life. I share the apartment with two other girls, so I am also trying to work out if we each need our own.
Who did you actually go with? What are you paying a month?
The 100k liability line is standard now, almost every lease I have seen in the last couple of years asks for it, and most management companies also want to be listed as additional interest so they get told if you cancel. That part costs nothing, just send them the declarations page.
The number that actually matters is your personal property limit, not the liability. Most people take 20k or 30k without ever adding up what they own, and then find out the deductible is 1000. Price both, the gap between a 500 and a 1000 deductible is usually a couple of dollars a month.
One thing people miss, earthquake damage is not in a standard renters policy. Separate CEA renters coverage runs a few hundred a year, which is either obviously worth it or obviously not depending on how you sleep.
I bundled mine onto my auto policy and it was the easy call. Renters came out around 14 a month, but the multi policy discount took more than that off the car side, so it effectively paid for itself.
If you already have car insurance, call your own agent before you shop around. Ten minutes on the phone, and you keep everything on one bill.
