Your last point hits home to me. We have two and a third due next month. Room is starting to get cramped, but I highly value a place where my kids can grow up entirely within its walls.

Also, I've done a lot of renovations to the home myself to cut cost and also update it faster: wood-look tile floors throughout, new flooring in bathrooms, update kitchen appliances & cabinets, deck, floor trim, etc. I often think that my commitment comes from all the blood and sweat (and even more tears) thrown into those things.
