I doubt It'll work long term which is something they'd actually need, as with basically everything they've tried so far as soon as it's gone, demand instantly collapses.
The only way to increase demand is to set a price floor for housing, guarantee a price floor for houses. Buy empty houses and change it to social housing. Provide support so housing prices plateau and even slowly turned upward.
Increase social safety nets. Increase medical coverage. Perhaps make children medical care completely free. Decrease burden on house holds.
Adjust the pension system. Either increase the retirement age to 65 or use pension to buy into the stock market massively, get others to buy into the stock market as a wealth generator. Use state funds to buy the stock market as well.
Then will you see demand increase.
