Your vegetable garden is pointless without a fence to keep out rabbits; likewise, your home financial plan will come to nothing without an insurance “fence”:

Homeowner’s insurance. Basic coverage for your home and everything in it. The average cost is $636 per year but this varies widely by state.

Liability coverage. Protects you from a lawsuit if someone gets hurt on your property, for example. Your best bet: An umbrella policy. For about $300 a year you can by a typical $1 million policy.

Various disaster insurance policies. Optional policies cover flood, earthquake, and hurricane damage. As part of your home financial plan, you have to research to see what disaster coverage, if any, you need in your area, and what your standard policy already covers. For $540 a year you can buy flood insurance, for example.

Don’t under- or overbuy insurance
For your basic policy, get homeowners insurance with full replacement coverage in case your house burns to the ground.

That sounds simple, but heads up on calculation. Remember that you own a house as well as the land on which it sits. So even though you bought your home for $300,000, it may cost only $100,000 to rebuild it. Your policy limits should reflect this. This difference will vary widely by region.

Another heads up: Don’t make the common and potentially disastrous mistake of thinking that because your home has fallen in value you need less insurance. If you bought a $1.2 million townhouse in Florida during the boom, it’s true it now may only sell for $600,000. But the replacement cost of the townhouse hasn’t changed much, so you can’t improve your home financial plan by cutting insurance costs that way.

Other ways to cut your insurance budget:
  • If you make structural improvements, such as adding storm shutters, your insurer may give you a break.
  • If you belong to certain groups, such as AARP or veterans’ organizations, your premiums may be lower.
