@JR T.
This is interesting because I have just spent the last couple hours researching whether or not to self-insure our portfolio. (Of course, as discussed in this thread, I would keep substantial liability coverage).
What I found is that the statistical value of the property insurance, based on Claim Frequency (percentage of households making a claim each year) and Claim Severity (average payout for each claim), in the categories of Fire & Lightning, Wind & Hail, Water Damage & Freezing, and "All Other Property Damage" pales in comparison to the premiums charged. Furthermore, I found that, with the exception of Fire & Lightning, the average claim is less than the $10K deductible I carry on most of our properties, which suggests that I am getting extremely little statistical return on those premiums.
My conclusion is that I am either going to lower my deductibles so that I actually get some statistical return, or I am going to drop the insurance altogether (again, except for a nice hefty umbrella liability policy).
Here's the stats: http://www.iii.org/fact-statistic/homeowners-and-r...
Disclaimer - as far as I know this is for single family residences only. Not sure.
What I did was to create a spreadsheet whereby I extended the claim frequency by the number of properties (to figure out what the probability is of having any claim in a given year). I then applied this percentage to the average payout for each category after subtracting varying deductibles, for a comparative analysis looking at a few different deductible levels. Sum up all categories, and you have the statistically expected payout for each deductible level. Unfortunately, the analysis is flawed because I don't have data for claim frequency above each deductible amount, and average payout of those claims. However, it's close enough to see some interesting things. Most notably, the analysis is sound with a $0 deductible, and the statistical value at $0 deductible still doesn't even outweigh the premiums at a $10K deductible. I have an email into my agent to get estimated premiums at varying deductible levels so I can plug in the numbers and compare apples to apples.
My conclusion: What we all knew already anyway, which is that insurance premiums have to be more than the actual value of the coverage because they have to include operating expenses and profits for the carriers. My analysis just really hit it home. I strongly believe that insurance should only be used to protect oneself from a loss that one can not sustain (meaning that if you can absorb a potential loss, don't insure against it because it is statistically, and in all probability, a losing proposition). This leaves liability insurance and catastrophic healthcare coverage as the only policies that seem to make any fiscal sense in our case.
Now I just have to decide whether the difference between the policy premiums and the statistically expected payout is a price I'm willing to pay for the peace of mind, or if I'll do what I know makes most financial sense and just self-insure.
