Those 3 investment firms, as well as about a dozen others will probably hold the majority of real estate as well, in 20 years.
Back to real estate (I'm rather busy, and can't keep up..)
If you are that desperate for the condo experience, just buy a small house and pay contractors and service providers to do everything for you, while you relax in air conditioned comfort. At least you will be in control of what goes on... Most HOAs are like handing a blank check to your worst enemy.
HOAs and dumb neighbors often result in lawsuits, and yes, it is totally true that the HOA can go broke, and everyone gets tied up in legal disputes for the next decade. Some highrises have monthly HOA fees of $3-10k!
