Right now we have assets including our home of around 600 k, with about half of that as home equity. The California real estate market seems to be heating up again, and if our house hits the mid 400k's again like it did in 2006, it might be very tempting to sell and RE, and live somewhere much cheaper. If this happens in say four or five years, I'd have accumulated another big chunk of new savings to go with this, so FIRE might be achievable in five years or so instead of ten or fifteen.
