Do you buy "Vacant Dwelling Policy" or just cross your fingers?

[Craig Barnthouse]

On the properties I have purchased, renovated and flipped to date, I have NOT bought "Vacant Dwelling" insurance. This was a huge oversight because I have funded everything with cash on hand and could have suffered a total loss of my investment if something catastrophic would have occurred 

I am about to close on another and will be buying this policy from here on out. I don't yet have a quote for this property, I know it's not worth the risk of being uninsured.

Do you flippers and rehabbers buy insurance on the vacant dwellings? If not, how do you manage your risk?
