Assuming it's still PS3 versus CV thread...
I currently live in PS3. As mentioned by many, 133 or Portola Pwky is the way to go. It adds a 5 to 10 min than living in CV but I enjoy the quietness, fresh air, clear sky, and hill background scene. If they indeed build some stores at Modjeska and Irvine, that will add more convenience. Also Spectrum is only about 10, 15 min away and some of the shops near Alton and Irvine are 10 min away in Mission Viejo direction.
I drop my kid off at Irvine High every morning. Via 133, it takes 10 to 15 min at the most. I used to live in Westpark which took that much or longer to the same school.
Resale value can be up in the air but I don't see any indicator that will drop the value in any newer part of Irvine. When/if Portola Elementary and high school start climbing up the rank, the value will only go up.
Not tracking TC but Legado selling prices climbed up quietly quite a bit, especially plan 4. OP mentioned plan 2 which is still below $900k but used to be low $800 to mid $800 only a year ago. It's not nice 4 bed layout with no loft.
Plan 4 is the most popular according to the sales team and I think 3 of them were sold over $1.05 million, which is not sustainable to me. I know the New Homes Cresa (?) next to Legado is a SFH with backyard and driveway with starting price of high $900. They might have sold out or closed already but why would anyone pay $1 mil for 4 bed condo now with others homes available is crazy to me. The plan 4 selling price was only high $800k last year so 20% increase and some 14 or 15 more phases to go in Portola 4...
