This question seems to be making the rounds this year. As there is less inventory on the market, coordinating timing for a move is hard and even harder when you have children either entering or already in school.
It is less disruptive to move when a child can start in finish a year in the same location. They have their friends, routine, extracurricular activities and such. However, trying to find the school with the right fit for your family can take you on a different course. Do you have to navigate a sale and purchase? Are you renting and need to plan a move in line with when your lease is up and can you go month to month? But when the big picture is considered it might make sense for your family to consider other options in a tight real estate market.
The best approach is guidance from a real estate expert in your area who can help your family make the best decision for your needs. They might even ask you questions you didn’t think to ask and throw all conventional wisdom up in the air. As with anything, educating yourself with help from a professional is a good start in the right direction.
