Thank you very much for all your opinions/suggestions!
We are actually in the middle of escrow process for a house (don't want to say which one) but found some fraud info and don't know if we should pursue. We are looking for a not so expensive house (around 500k), 1500 sq, 3 bed, good school but don't have to be great, good neighborhood, low HOA, low MR/tax, newer house (around 10 years). We don't want any yard work, so small yard is ok. Here are some of our findings:
1) Turtle rock area - houses either too old or too expensive
2) University park - houses too old and near to highway
3) Westpark - near to highway or too small or too expensive
4) El Camino - too old
5) Oak creek - too small or don't want the 2+ level house or not a lot of choices
6) Woodbridge - high HOA
7) Woodbury - high tax/HOA
8) Quail hill - close to highway+ high HOA
So Northwood/Walnut/Tustin field have some houses that we like, but saw so many negative comments about TF. We haven't look at Northpark or West Irvine. We thought as the school in Tustin ranch is the same as Northpark/WI, maybe we can find better deal in Tustin ranch? we also might be wrong.
Thanks again for sharing all your opinions!
