Limitations exist on certain items, e.g., a $500 total for jewelry. Talk to the agent about buying additional insurance on particularly valuable items.

Having a place to stay 'saved my world'

Nicole, a New Yorker who asked that her last name not be used, guesstimated how much her belongings were worth and bought insurance to match.

One year later a building fire displaced Nicole from her apartment. Because she had coverage, the freelance PR specialist was able to get a hotel room and keep working, instead of crashing on friends' couches and hunting for Wi-Fi at coffee shops.

"I was able to maintain a level of normalcy," she says. "My renter's insurance saved my world."

This "loss of use" coverage limits out at 20% to 50% of a policy's total value. Those who live in high cost-of-living areas should increase that part of the policy, according to Manhattan-based broker Mark Carrasquillo.

He speaks from experience: His parents were displaced after a fire. "They had to rent an apartment and their policy just barely had enough coverage," says Carrasquillo, of E.G. Bowman.

Make a list, check it twice

Getting renters insurance is relatively easy. Even though it's not always required, the professionals with whom I spoke strongly recommend that you document your property. This can be as simple as taking cell-phone video of each room.

Open every drawer, and scan every shelf in the closet or cupboard. Focus clearly on the serial number of your laptop or the receipt for that new television. Store the video somewhere else, e.g., send a copy of it to your parents or friends. You may also choose to digitize and store receipts online.

The Insurance Information Institute has free inventory software at a site called KnowYourStuff.org.

Some renters still use pen and paper to catalog their belongings, including serial numbers. Your agent may provide an inventory checklist, or you can print out Wells Fargo's property inventory.

A good time to do this is right after the holidays. Not only are you documenting gifts you received, you're getting a clear picture of holiday décor, china, ornaments and the like. (Procrastinators take note: Now you can feel good about not having put all that stuff away.)

Don't forget items stored in the garage, attic, crawl space or bathroom vanity. It's amazing when you add up how much you've invested in wine, tools, craft/hobby supplies (hi there, yarn addicts!) or expensive cosmetics.

Wells Fargo spokeswoman Melanie Donaghy tells of one woman who discovered she owned about $1,000 worth of hair- and skin-care items -- and don't get her started on the shoe collection.

Imagine replacing all that. Renters insurance, Donaghy says, "is legally optional, but it probably isn't financially optional."

Tips from the pros

Don't put this off. Buy a basic level today, as in right now. Call the company that insures your house and/or car, or search online for a quote.

Over the next couple of weeks make an inventory of your belongings (yet another way that 20 minutes at a time can save you big bucks). Check with an agent and add more coverage if necessary.

Things to consider:

  • Look for discounts. The company that covers your home and/or auto may give you a deal, Carrasquillo says. You might also get a good-student discount, a senior discount or a military discount.
  • Ask the agent if you need an appraisal for particularly valuable items. They may just take your word for it.
  • Got roommates? Get separate policies. You want full coverage on your own stuff, and you don't want to be attached to a roomie who's found liable for damage or injury. "Would you share a car insurance policy with your roommate?" says Eric Narcisco.
  • If your budget is really tight, ask about paying by the month. As with other kinds of financing, this will likely cost you a little more per year. But at least you'll be covered.
  • Just as you store your virtual inventory somewhere else, keep your insurance contact info off-premises, too. Put the agent's name in your cell phone but e-mail the info to yourself (and maybe a relative) in case your cell phone is one of the things that gets stolen or destroyed.
  • Are you the forgetful type? Consider setting up your policy to renew automatically.
  • If your apartment becomes uninhabitable, keep receipts for everything you buy until you get back home. After a wildfire caused Barbara Adolph to flee her northern Los Angeles County rental, the insurance company paid for everything from new toiletries to food for her dogs.
  • Consider "replacement" coverage versus "actual cash value" coverage. That five-year-old couch has depreciated, so the insurance company won't give you what you paid if you have a cash-value policy. Replacement coverage will let you buy a new one that's just as nice.
