technically the numeric prices of houses may not actually go down, but your share will decrease starting in 2020 as shared equity mortgages become mainstream. When the price of a house goes up, normally you gain numerically, but with shared equity the banks get to sell that numerical gain to investors. You will probably hear arguments that shared equity is meant to lower the price of a home for a first time buyer, but it will impact all home owners as the value of fiat plummets but the stake you have in your home remains at the same numeric amount. 

This could actually trigger a home price meltdown I think later when investors want a larger cut of the equity and start buying out the remaining share of the home from the people living in it. 

But short term the equity people think they have in their homes is going to shrink in real value as investors steal the rest, which I think will lead to homeowners selling off their equity for liquidity, and causing a buyers market.

**edit** as for bitcoin, gold and silver going up, the extreme excess liquidity that's ramping up will need to go somewhere, and while it has initially gone into stocks, its not going to stay there, and banks don't offer any meaningful gains on any investments they offer (and average annual rate of return is an obvious scam), so the only thing left is metals and any other safe haven, and the liquidity that gets funneled into real estate isn't going to help home owners, aside from short term liquidity if they choose to sell off their equity.

**2nd edit**  I guess I should clarify. If you are someone that ones your own house outright with no mortgage or line of credit, and you are financially well off, then none of the above applies to you. If you do have a mortgage or a line of credit that you can't pay off in full without needing time, then  you may find your bank contacting you soon to "offer" you a shared equity mortgage, with the alternative being that you pay off your line of credit immediately (as these are often business related), or if you simply have a mortgage you are paying then they may offer reduced payments if you switch to a shared equity mortgage.
