"4. carry insurance"
Insurance is good but keep the deductible as high as you can.
Excellent point Art. Especially significant with homeowner's insurance.
And speaking of homes, if your home loan carries an interest rate >7%, do an analysis to determine if a refinance would be cost effective. Choosing right lender obviously key, and closing costs need to be factored into the payback analysis, but a typical $200K balance @ 7% should reduce down to ~5.5%, with a ~$200 reduction in payment. Continuing with the original payment retires the loan in 21 years. Despite turmoil in the mortgage markets, if you're creditworthy, can still easily obtain a competitive mortgage.
Finally, with soft/declining RE values pretty much everywhere, look at your home's valuation on the tax rolls. If you bought your home within the last 3-4 years, quite possible you can file a (supported) request to have valuation marked to today's value, thus reducing property tax. I did it in California mid-90s, and dropped property tax by ~$400.
