I'm not exactly saying not having a family is a sacrifice, but where you want to live. The cheapest apartment I could find in my area (before kids/marriage) was about $700 and that's a few cities away in a no-so-great area where cops were getting called to our neighbors every few days. I could go closer to downtown and be in a worse area.

With kids, the cheaper areas have generally worse schools, parks, etc.
