Think Covid-19 disease influenced a lot on decision of many citizens to buy suburban housing by means of mortgage. Don’t think that crypto can somehow to help in building new houses and to lower prices on them. Scarce goods always inflate in price. Only oversupply of houses can help to decrease prices or, probably, the full end of covid-quarantine.
This problem has been persisting even before the pandemic, 1970s is the right time to buy houses because they are the most stable time and less expensive economy back then but now that real estate skyrocketed in prices because of increase in population and business which made land more valuable and the 2008 housing crisis also contributed to the destitution of many people in USA, oversupply in real estate does not work the same as the basic supply and demand.
But 1970 is a long time away, how can a young family these days ever afford their own house? The housing crisis in 2007/2008 was only a small dip on the average house prices. If you had money at that time you could have managed to buy a few bargains. However, since then the prices rose very high again. It is nearly impossible to buy an house these days with an average income. For example, if I would just buy an apartment right now with my salary and take out a loan for 75% of the value I would have to repay the loan for the next 35 years. This is insane, who knows what is going to happen to in 10 or 20 years, how can you go into debt for such long times?
