Although it is not precisely the same topic we are discussing, this is the best article I ever read on paying off mortgage vs investing: https://financialmentor.com/investment-advice/pay-off-mortgage-early-or-invest/7478
he does extend the logical argument towards the end of the article and says that if you are in the "invest" camp then to remain logically consistent you should also be willing to take home equity out of your home, and because this isn't a very common thing then he acknowledges that it is always a question of doing what you feel comfortable with.
Ultimately it always boils down to risk vs reward.
The downside risk will always be a 100% loss if the bank decides to repossess, regardless of if you have $1 or $1m outstanding. This is why I pay down no mortgage debt and focus on my investments.
What? That's not true, the bank doesn't get to just pull a "gotcha" and take the house for $1 of outstanding debt. You still own the equity.
This seems to be a pretty common misconception for some reason. A mortgage is a secured transaction, with the house as an asset that can be liquidated
to satisfy the outstanding debt. If it sells at foreclosure auction for $100k, but the bank is only owed $10k, they take $10k out of the proceeds and the rest either goes to the next creditor in line (usually people who get foreclosed on have more than one creditor) or if there are no other creditors in line, the borrower who owns the remaining equity in the house. Of course, the sale proceeds will probably be a lot lower in a foreclosure than in a typical resale, and associated costs and fees will eat into that equity, so borrower is worse off than if they saw the cash flow failure coming and sold ahead of foreclosure.
If vand means "100% loss" as in you 100% do not live in your home anymore because someone else owns it now and you have to move, I suppose that's correct. :)
