They began buying residential real estate as an investment to offset the hits they were taking on commercial properties that were sitting unused because of the pandemic. They've been gobbling up massive amounts of residential real estate in the past few years.
From an individual homeowner perspective, the properties they turn into rental units are typically run by a management company. Say what you will about certain landlords, at least there's somebody to drive issues to. Property management company? Not so much. You really think they care about complaining neighbors?

At a larger perspective, residential homeownership is the biggest driver of wealth in the country. The biggest asset on most people balance sheet is their home. Owning a home is typically the first step to building your personal balance sheet and that typically even extends to your children, creating generational wealth. Homes occupied by their owner have a natural incentive to maintain their investment. This is how neighborhoods are made. Structured buying of those properties, with some localities are showing corporate investors buying more than 25% of available housing stock, prevents this wealth and these neighborhoods from developing. It prevents people from buying homes, it keeps them in rentals longer, it stops the creation of wealth, and it damages communities.
