Before you request a container for Foreclosure Cleanout, know that it is a property emptied to a deadline, frequently with unknown contents and no services connected. That single fact changes the conversation. The part of this job people find out too late is that no power or water on site changes what crews can do and how long it takes.
The number stenciled on the side of the container is a volume, not a weight limit, and the weight limit is the one that actually gets enforced. The booking pattern here skews toward banks, realtors and investors, since the job produces a fairly predictable volume of debris, which is why 20 or 30 yard containers cover most of what actually gets ordered. Skip the back-and-forth by knowing two things up front: clearance for delivery, and whether the container will sit on the street or the driveway.
This kind of job changes as it goes, so the debris mix on day one rarely matches the debris mix on day three. Leave room to size up instead of guessing the exact fit. Settle who is responsible for driveway damage. Concrete cracks and asphalt divots happen often enough that some haulers offer boards to spread the weight, others don't. The size on the container door is a legal limit, not a suggestion. Treat the fill line as the actual boundary when you decide what goes in first.
