It is better to make sure that you compare apples to apples. For example, there are some incredible homes in Sandpoint and you don't want the waterfront properties and great view parcels bringing the "average price per square foot" up (unless that is what you are trying to buy too).
A good Realtor can help you narrow it down for a specific home style and location instead of just a general shot in the dark answer.
If you are getting a loan, your lender will require an appraisal be done and typically the appraisal has to come in at or higher than the sales price or the lender won't lend you the money to buy it!
I used to work for a company that had an office up in Sandpoint so if you would like some direct assistance, let me know.
Best of luck!
