best insurance to get when doing a flip

[Elizabeth Blazina]

Hi, I am currently doing a rehab and the property will be vacant.  My last one was a looong time ago but I do remember the crazy insurance cost.  Is there an insurance company one would recommend in Washington state.. although I am not sure that matters.  Also with premiums, where you discounted the days you did not actually use. For example a 3 month flip only taking 2 months. 

Thank you for any insight.
