If it's been an unusually snowy winter and it's all beginning to melt, it may be coming in from outside.  

Is that unusual, or fairly common?

you could have the owner put you on the policy as 'additionally insured' this is not unusual, property managers request this all the time.

There was also a house built in 2006 on the same street that sold for 156k but I discounted that being it is a much newer home.As an update I got in contact with the listing agent and was instructed to deal directly with the owner, which I thought was unusual.

If there are very few common elements that the association is responsible for, it's not unusual for insurance to be a good part of the fee.  

My unusual living arrangements.

I'm not sure why - it's like I've had an unusual string of bad luck.

Downtown Cleveland has been a stand-in for New York City on several occasions in various movies, and offers an unusually urban environment for a city of its size.

That would be unusual because they're pretty different designs.

I just called my title company to ask about this but is this an unusual request?
