It says “quiet cul-de-sac,” but I doubt it. Make sure you go there at rush hour (and probably any other hour, for that matter) and see what the noise level is from the very-near-by 56 freeway.
Also, even though you’re right next to the freeway, you’ve got to drive a couple miles through some traffic lights to actually get on the freeway.
The schools are, I’m pretty sure, Poway school district. You hear they’re great, and I’m sure they’re fine. But I think they’ve overrated. Anyway, they’re not as good as the schools that you go to if you live in the more western parts of Carmel Valley.
In short, there are reasons the house is less than 600k. Which is not to say that it’s not worth it (nor that it is). Just a few observations.
