My sister bought a house sight unseen last year when she had to move all the way across the country for her job.When she first told me that this was what she was planning on doing, I thought that it was the craziest thing that I had ever heard of. I had never heard of a person ever moving to a brand new house without even seeing it first! She said that in her line of work, where people have to move a lot, people do it all the time. I still thought it was weird, but I trusted her judgment. She said that she started to work with a realtor who specialized in that sort of thing and those types of moves. She told him that the only thing that she was really concerned about in the new house was the heating, cooling, and ventilation system. My sister is very paranoid about the indoor air quality wherever she is living. I think that this is especially true when she is moving to a new area. She is terrified of getting sick, and she wants to make sure that her respiratory system is always at its best. So when she talked to the realtor, she told him that she wanted a state of the art, high efficiency heating and cooling system in the new house. She also told him that she wanted a whole home UV light air purification system set up to run in tandem with the HVAC system. She said that she would prefer to have a fireplace, too, but that wasn’t a deal breaker for her. Other than that, she didn’t really care about the house at all.
