Collusion using online management services to fix prices across a region.
I think Washington State is working on legislation around rental services due to this already being a problem in the Seattle area.
“Extra supply” is added to the portfolio containing housing they’ve already purchased. They own part of “existing supply” too.
Housing is a depreciating asset. Even if you're trying to continuously corner the market, you'll be losing money in the long run if you're not actually renting the units for more than you're buying them for.
If supply can be built to meet demand, trying to corner the market to achieve monopoly rents will fail in the long run.
Collusion on housing only works when there is a shortage. As soon as the shortage ends units go unfilled and landlords defect. Collusion works in industries where supply can change in the short run, tough to do that in real estate. Real estate elasticity is so high though that small collusion can work, but only if there is already a shortage. Yet, again the solution is just build more.
There are too many competing landlords to form a functional cartel.
Why this collusion doesn’t happen in Austin where rents are falling 2 years in a row?
I live in Seattle, and this is a scapegoat. it's another way to point a finger at anything but massive restrictions on supply. The easiest solution to collusion to keep prices high is to let lots of other people build and compete down price. In Washington, most new construction happens on a very small number of parcels, because that's the only place we allow it.
