How do you get the inventory? Are you using a standard property API like the rest? Or is most of this a manual process at this point and is that why you are focusing on one city?
We’re focused on one city because real estate is inherently hyperlocal. Being the default marketplace for SF requires local supply controls and city-specific features that don’t generalize well at national scale. (For example, we have something as simple as a rent control toggle)
National platforms are built for everyone, which usually means generic filters and shallow context. SF renters care about things like rent control, transit lines, block-level differences and other details that get flattened at national scale.
