Dear Monty: At some point in the next few years, we will sell our home. We have been here 25 years and raised our kids here. My wife and I have resisted modern technology. We get along fine with paper road maps. I have an old flip phone, but my work is outdoors, and my hobbies are hunting, fishing and collecting rocks. My family, friends and co-workers poke fun at me. My brother, a few years younger, warned me that if I don’t get with the program, I could be at a disadvantage when we sell our home, relocate and buy again. Is he right?…
