Another point to consider is Texas has no state income tax. I’ve known and have family moved to no income state tax places, but they all make in the 300+ – million rates so it’s an easier “financial” decision when you don’t pay another 30k – 100k in just state income taxes.
Personally, I’d keep the place in CA unless I needed to sell because as expensive as it is here, there are places in LA, Bay Area, NY, pretty much all the large cities in Asia (Tokyo, Hong Kong, Beijing, Shanghai, Singapore) where people are happy to park some cash outside (for their kids too to go to school). SD isn’t bay area, but it’s “good enough” for most of those folks…and getting into UCB and UCLA is hard nowadays, even with them opening it up a lot more.
In terms of supply, the builders simply don’t build SFHs unless they are sold pretty much. There is no competition in some areas (think Pardee and CV) so good luck trying to expect prices to fall when, as mentioned in the other thread, housing construction is probably half of what it was in the past and the millennials are starting to hit the start a family age…
Safer to keep it for now and rent in Austin to see how it goes.
