The way in Europe is that, they eliminated their doormen after 60s and 70s when human labor became expensive. Each building in Europe just hire a cleaning person, she/he comes a few times a week and clean, and distribute the bills and report problems to the building president, when there is a need to fix something, there will be a special assessment. Thus, in Athens, 30-50- euro a month is standard, property tax is low, about 8 euro per sq meter a year, so if your apt is 100 meter, you pay 800 euro a year. In Paris, many places have the monthly fee under 100 euros. Only the super high end buildings have real doorman. 1-2 million euro apartment in Paris is considered middle class or higher, hardly considered high end. In China, the HOA (home owner association ) is big and professional, they manage to keep the fees low. If the home owners are pissed off, they just do not pay the monthly fee and there is no much you can do about it.
Argentina adopted the doorman system from Europe (many old buildings in Europe still have the doormen desk, living in apartment and telephone switch board, that the doorman can connect to any flat, like an old company phone switch board). But when things got difficult, Argentine home owners were never able to get rid of the living in doorman, which turned into a disaster. Not sure if it was due to the union or other reasons, the doorman system in Argentina is a cancer to home ownership. It makes it much harder for older people to hang on their homes when they stopped having good incomes coming in. US have high real estate tax, but it goes up slowly for long time home owner. Poor argies, when they are retired, the monthly is going with the current inflation ..
