Personally, I believe it will settle in between the naysayers who are calling this end of office real estate as we know it and believing that everything will go back to the similar amount of appetite for office space.
CoStar (commercial real estate analytics provider) published an article (there is a paywall for CoStar) about office workers' productivity working from home, and their preferences working in the office in the future. 40% of respondents said they were less productive at home, while 22% said they were more productive, but at the cost of working more hours. 50% of respondents preferred some type of flexible policy of splitting time between the office and home.
As Covid-19 continues to overhang the global economic future, it has sped up the consolidation and closing of the retail market that e-commerce had already started. Additionally, it has brought to mind to companies their global and national footprint and this will slim the appetite/need for office space.
As residents have more flexibility in where they work, they won't have to be tied to the downtown areas where the prime central business office space is located. They will have the flexibility to rent/or buy in a suburb that might be further away from the office. As they spend more time in their local residential areas, there will be more localized demand around their residences than there was previously was if they were commuting to work every day, spending a night out on the town, and only coming back to their house/apartment to sleep.
