The 5 to 7 year average isn’t mine, just what I’ve heard. It actually shouldn’t even be a range like that, rather just a number (like 6.8 or 14.2). I’d think either the NAR or some government source (or both) would have this number. Heck, there should even be a number for the number of homes people own in their lifetime.
Heck, I’d say the point I’m really trying to make is that people go through several homes before hunkering down. I don’t know a good way to figure that out, so I figured we’d try to back into it with tenure.
I understand about the clock ticking thing, but again, ignoring previous tenures for homes when they’re short is going to skew things as well. It’s really all prior ownership that’s going to give you precise length of ownership numbers (right?). No matter how one does it, the key is to be consistent.
For a new street, let’s follow Bugs lead and try Mt. Elbrus in Clairemont. I don’t know if there are power lines or not, but it looks like it’s near a park, so that’s usually good.
Finally, I agree with you that I think tenures are going to trend upward, but I’d probably refer to it as dropping anchor rather than laying down roots! This will, of course, be skewed by some of these foreclosures we seem to be hearing about, so who knows what where the “average” will go.
