Pre crash it wasn't unheard of for people in places like California to use the equity in their homes like other people use ATM machines.
There were people on non spectacular incomes living pretty nice lives, spending what they thought was more or less the same as ".banked" money. Post crash, they were fucked beyond the edge of fucked. Bankrupt at a time of their life when they had dependants who struggled to adjust to their new normal, and not enough years left to start again from scratch.
Equity is imaginary money right until the point somebody buys your house and gives you lovely ,solid, real cash. You don't know if "your" equity is real or fantasy based on inflated assumptions until you cash it in, or quail at the news story announcing the house price crash of the millennium.
What you are doing is using a very expensive (due to the long term of the loan) form of debt accumulation to pay for the school fees.
Post crash, when the writing on the wall is in Ten Foot Letters that consolidating your security is far far better life/mental health protection for all family members in an uncertain world than beefing up your insecurity.... you are beefing up your insecurity.
I don't think you got very good advice from the perspective of the bigger picture.
Not when our generation cannot be certain that we will attract even the current level of state support for older people, or under employed people.
Not when our generation is going to have to compete for longer in a global job market, being all expensive compared to bright young things and perhaps a bit lagging and knackered in keeping up with the "new and shiny" curve in our industries.
It is not selfish to consider your longer term security as a couple as a priority. Everybody in the family suffers if a downturn, a change of fortunes or bad luck in the form of accident/illness/joblessness what could have been a manageable drama, into a full blown crisis.
And then there are the Not So Golden Years. We looked after FIL and MIL, the latter in our home. The strain of trying to bring up our own family, work and take care of the previous generation nearly broke us. I don't want that for DS. There would be no point to our having run a veritable marathon obstacle course to get him access to decent education, only to turn around and blight his life with heavy duty obligations towards us, so he couldn't reap the rewards or enjoy the life we have tried so hard to make accessible to him.
Do you see what I mean ? It's not a case of a legal and well known f. product validating your choices. It's about the bigger picture and how the choices you make have ramifications in other areanas in a future you have no way of knowing the details of.
I really would think about a Family Finance WellBeing Check Up. Not one where products sold pay for the time invested by the expert. Not one focused on paying for a specific thing. One that is solely focused on showing you the pros and cons of the various routes available to you in bigger picture terms, so you can chose based on being fully informed rather than maybe stumbling about in the dark, not even knowing what you don't know.
I promise I am not being horrible. I didn't know what I didn't know. In some ways life was easier when I didn't. But on the other hand, I am ".life biting me on the bum when I didn't know my arse was exposed" averse, so it is better this way.
