Plus it is overpriced by almost 100%.

I would hope that before one buys, they'll check out to ensure permits were pulled for the additions. The property assessor's site will show the size & amount of rooms in a house - if no permits, they won't be reflected on the assessor's tax appraisal. However, I'd check at the county building dept.

And check out that location. On a busy road that leads directly to a freeway on/off ramp. Perfect for sitting outside in tranquility, no traffic sounds.
