It is a proven fact throughout the US that whenever Interstates or Highways are increased in size that they soon (meaning within 5 yrs) become full of traffic again. With this in mind the extension of Rte 7 should eventually have an effect on the value of Real Estate in NM. It just won't happen over night. I beleive that NM is a great town to buy a home at the present time. I always suggest NM to my buyers since I think they will get the most return on their investment if they are willing to wait a while.
