Your family is growing and so are your kids. Now, you feel that your family needs a bigger place so you can give your kids a better environment to live in. Though it would be a really challenging decision, moving will also bring more good things and opportunities to you and your family once it materializes.
Homeowners prefer bigger place especially if they have bigger family. People who plan to move to a new home consider a lot of things before eventually moving in. The location of the new home is the main priority. Is the place near to the market, the church, the city hall, the clinic or the hospital, the shopping centre, the school, or your work place?
Another thing that matters is the kind of environment. Your children should grow to a community that is resided by friendly, kind, and loving people. Though it will be hard to find such neighbourhood, it's possible. You have to research about the place carefully until you find the right one. If all your expectations of  a new home is met and all your needs will be provided by the strategic location of the new home, then you know is time to move out your old home and move in to your newly-found haven.
