Insurance an issue!!!

So I decided to refinance my town home instead of selling it. We have experienced a surplus of real estate in the past few months and homes are not selling quite as quick as last summer. My loan was all but ready to close when I realized I didn't have enough insurance coverage to satisfy the mortgage company financing my loan. My townhome appraised at 215K so I assumed I would need at least enough insurance to cover the dollar amount of the loan. I found out that USAA would not insure my home for nearly the amount I needed so I started to look elsewhere. One insurance company gave me the ok on the amount of coverage I needed but it was going to take them a minimum of 2 weeks to send an inspector out. Seeing as how my rate lock would expire before the two week window I had to find an alternative solution. The appraiser on my town home failed to put a replacement cost value on the appraisal so I called the appraiser and begged for his help. After much feet draggin they finally delivered a replacement cost I could live with and the mortgage company said I needed at least 80% of the replacement cost in insurance coverage. I called USAA back and low and behold I got coverage through them...With a whopping $1000 dollars to spare. Lucky....perhaps.....but it goes to show a major problem with the retail values that appraisers are giving on homes in relation to the value of your home based on the Insurance companies policies and practices.
