You nailed it Paul. This COVID has been a nightmare for many locals but also owners as well. At least it sounds like your building is allowing strangers/renters in the building. Mine has forbid anyone except the actual owners for months since the lockdown. I believe they will finally in 2 weeks allow people to start, but it's been brutal especially since I had several that wanted to rent my property. I had a friend stuck in Buenos Aires and also wanted to let him use my property free and the building wouldn't allow him to enter. Some buildings are super paranoid.One does not always make money on rentals. The rents have fallen but not my expenses as a landlord. Sometimes we win, sometimes we lose. Many are experiencing hard times now. It´s just part of life.
I have other friends that were in long term leases with expats that were living in Argentina for years and just because they were from the USA, the building changed the locks and would no longer let them in so naturally the tenant stopped paying their lease and moved on leaving the owner to an empty apartment that no one has seen in months since she lives in the UK.
