In another life when I was in the consumer electronics industry we talked a lot about seasonality. Sure that was before internet shopping was widely available. However, as I have said many times before the real estate market is just that an economic market that will anticipate and react to certain timing.
An example in some markets the families would like to be settled in before school starts.
In some markets perhaps the weather has a tremors effect. Spring is a very good season in the real estate market for many different reasons. Sellers in the north have a better time selling their homes which makes it easier for them to buy in warmer climates.
The reasons for seasonality are many and one could write a book on this topic. The purpose of this article is to point out that different markets will have different seasons and timing. It is as important as the correct pricing which is a whole other subject.
