I am a real estate agent in Show Low, Az and can help you with all your real estate needs up here! You can go to my web site listed below and I can get on the White Mountains MLS. Please call me for specifics on homes sold in the area.

Teresa,
If they are being marketed in the local MLS you can ask a local real estate agent for information on pending sales.
Of course you will not know the negotiated price of the property.
If you are just looking for numbers Trulia or Zillow will have some, if not all of the sales in your area.
If you are looking for specific properties it might be best to check your county website. The easiest way is to talk to a Realtor member of the MLS.
