First, begin by contacting the local Taos Board of Realtors for contact information on the several of your local brokerages. Then call the managing broker and ask them to make a referral to an expereinced agent and/or property manager who can begin to work with you to find your rent with option to purchase home. The phone is 575-758-7411 and their web site is http://www.taosmls.net.
My recommend would be to find an experienced Realtor who knows your market and would be best informed on current opportunties. Best of luck in your efforts!
