I d ran some comps for you and posted them on my website below for you. From an inital look I'd say YES it's over priced.. but it does have a guest house, so knowing the rent for the guest house would be critical. I've included a break down of the active, pending, and solds in the are ( and contingent which you should somewhat disregard)
You will find an in depth analysis ( a semi in depth one) regarding price per sq sales in the general area near the Carlsbad High School. Should you need more info use my website to see active homes that are on the list below or call me to email you the photos of the comps so you can compare apples to apples. Seems like there are great opportunties happening in this region , based on the comps.
