The question home buyers always ask me when they find a home they like is why are they selling.  There is a fear that there is something wrong with the home they just fell in love with.  The National Association of Realtors did a study of the primary reason why homes are sold.  Here it is.  

19% - Sell because of a change in family situation

17% - Sell because the home is too small

11% - Sell because of job relocation

That's almost half of it right there.  Other reasons are because the house is too big, retirement, or to move closer to family etc.  Interesting?  I think so.
