How straight is the grain? Lots of trees growing in suburban yards take on the aspects of what was known as a "pasture pine". Without competition for light, they tend to put out large branches at relatively low levels, which means that the wood is short, twisty, and loaded with knots. For some wood, that may increase the value, as the wood has real character...you don't hear that much, though.
A tree in a mature forest has to get tall, fast, so it grows up faster than out, resulting in long, straight, wood.
