The idea isn't to borrowing against your home to invest.
Rather, the idea is that after you have your mortgage, you put your extra money towards your stock/bond investments rather than putting extra money into the mortgage to pay it off early.
This is because the interest on your mortgage is quite low compared to the long-term stock market returns (7-8% after taxes/inflation). So your dollars are more valuable there than spent paying off your mortgage.
In other words, if you take two people, each buys the same home, but one pours all their extra money into their home and the other pours it into the stock market, in 20-30 years the one who poured all the extra money into the stock market would have a much higher net worth.
I don't think real estate/paying into your mortgage is risk-free. I'd say it's about as risky as long term investments into the stock market.
Over all of recorded history, the stock market has gone up 10%/year on average (not accounting for taxes/inflation).
The common rebuttal to that is that past performance is not an indicator of future performance.
Sure, but then you have to apply the same logic to the supposedly "risk-free" real estate. I think it's just as likely that your house becomes worthless as the stock market no longer giving 10% returns.
My more general argument is that for all intents and purposes the stock market is a gauge of the overall economy. If suddenly the stock market stopped returning 10%/yr the economy as a whole would be in serious trouble. No investments, real estate or otherwise, would be safe. Your stocks would be as worthless as money stashed under a mattress.
That's my logic, at least. Of course, as I said, I don't follow that logic personally. Not that I don't agree with it, just that I'm willing to sacrifice financially in exchange for the satisfaction of owning our home.
I'm afraid your logic is a bit flawed here. The home value increase or decrease does not factor in when considering your mortgage. Your mortgage continues to exist no matter where your home value goes.
You have to pay that same mortgage even if the market tanks and your home becomes worthless. Even in the case of just "letting it go" the bank will take your worthless house and will still come after you for what remains on the mortgage.
That is why putting money into your mortgage is a "risk free" investment at 4% (or whatever your rate is).
