My concern with detached condos is that there is the risk that they could fall into "no man's land" in terms of housing inventory. Look, there are roughly two classes of homebuyers, those looking for attached homes, and those looking for true SFRs. It seems that high demand in Irvine may have prompted many would-be SFR buyers to settle for the detached condo product because of the high price points. If available inventory for SFR is limited, the detached condo should do pretty well given that families are probably willing to trade off just to live in Irvine.
My vibe from what developers have been saying about Great Park is that there will be a lot a SFRs coming online in a few years with "real" front/back yards and driveways. Unless they price these well north of $1 million, detached condo owners could find themselves in no man's land if they want to sell by then.
