Is State Farm Ripping Me Off?

[Larry Alexander]

Colorado Home Single Family Homes
1.) New construction SFH 2145 sq ft | 4 bd 3 ba
Insurance: 593.00 on a 359k home

2.) 2003 SFH 2048 sq ft " 4 bd 2 ba
Insurance: 799.00 on a 330k home

3.) 1993 SFH 2184 sq ft 4 bd 3 ba

How on earth is #3 about double?! Seriously, $1,491 for a policy? What am I missing?

All are through our State Farm agent, whom had everything; Our personal home, four cars etc.

I think I need counseling and advice.
