The truth is, there will always be another house. Every year, more than 4.5 million homes are sold. Every, at least, two or three homes sell on my block. In the past six years, two of the houses on my block have sold twice each. This is true for most neighborhoods.
Houses come on and off the market at all times of the year.
While you may have a dry stretch, in which you don't see anything you like, don't compromise. The right house is just around the corner.
