I live in Manhattan, NYC and grew up here in the city. I'm concerned that we're going to see a reversal of urbanization due to the pandemic. I think what COVID has done is
1) sped up the migration of millennials to the nearby suburbs - NJ, Westchester, LI
2) new permanent work from home policy changes lead by the tech industry (Twitter, Facebook) which will echo across industries will make people reconsider where they want to live. That's never been an option until now. A lot of permanent flexible work from home corporate policies (esp in the finance, insurance sectors) are up in the air at the moment and not finalized. As people work from home more they're going to want to have more space and would want to leave densely populated cities. Another issue here is shared washer/dryer space in mega apartment complexes - that alone might be enough to move me!! State income tax would be another consideration. So I think what we're going to see is an exodus from densely populated urban cores to slightly smaller cities - esp to those in warmer climates and tax friendly states. Think Atlanta, Austin, Portland etc...
Going back to your original question - we're also seeing milder winters in NYC as well but it's tough living here. I only realized that when I left NYC to live elsewhere (SF, London, Germany, Shanghai, etc...and those aren't even small). If I were to leave to NYC I'd want to move to the bay area which is even more insanely expensive but I love being on the coast and easy access to gourmet sushi/japanese food is important to me! yes that's actually a consideration :)
