I think that house should be in the low $400k, not $500k. But that’s just me. That house is over priced compare to the other houses around that area. Here are some example:
This house:
1641 sq-ft listing @ $648k.
Other houses:
7144 BLAKSTAD CT., SD – Mira Mesa, CA 92126
1984 sq-ft listing @ $600k for over 70 days w/ no buyer.
7745 PRAIRIE SHADOW ROAD, SD – Mira Mesa, CA 92126
1826 sq-ft listing @ $625k for over 60 days w/ no buyer.
11845 GEHRING CT, SD – Mira Mesa, CA 92126
2102 sq-ft listing @ $645k for over 30 days w/ no buyer. This house is down the street from the house you posted. So location is almost identical.
