The homeowner's policy is insuring the home, not the seller, so it does not matter. Where the home is, your credit rating, your age, the type of home, replacement cost, deductible, etc. and more importantly the insurance company and their rates are what makes it different. Also, if you are going to occupy or rent it makes a big big difference.
Shop around a lot. There are a lot of companies out there and the rates differ unbelievably. And if you give them the home auto - multipolicy, that is the best savings.
Also, if you want to know about the consumer rating of the company, look on consumer reports, jd power or call the state department of insurance. You can find all online and they have a lot of good information.
