Underwriter requiring $300k in renters insurance--too much?

[David Zinn]

I am rehabbing a house that should appraise in the $140-145K range after renovations. The underwriter for our homeowner's insurance is requiring renters to have a renters insurance policy for no less than $300k in liabilities. 

Does this seem steep to you? Which insurance companies do you use and what are their policies on renters insurance?
