Personally love a neighborhood that’s walkable (retail, restaurants, coffee shops that’s a 10-20 min walk, a lot of young families live in these areas) and has a mix of housing- apartments (yes apartments), condos/townhomes, SFRs. You then get to see young families, kids, a nice mix of people in terms of ethnicity, income (to an extent, it’s Irvine after all and there are outliers but if most renters are paying $3k+ rent, they must have a decent income). Though for many being in a bubble is a feature and not a bug. Seen many comments on here that how a certain area even if it has plenty of SFR’s is “high density” housing (as if it’s Singapore or Hong Kong ha) because of the apartments or condos in the same area and there was a negative connotation in those comments where if you read between the lines it’s clear what’s being implied.
