Property next door

My neighbor saw me outside and told me that he will be retiring in Feb.
and putting his house on the market. Why do people feel the need to build
their dream house and then not stay in it. I would have bought the property
and gave myself the luxury of having a neighbor! Now I will have a neighbor
there and different ones as they buy and sell. Sure do hope I can afford
the 100 Acres in the country soon! Thus leaving the entire unknown neighbor
thing behind.
