However, can you unpack "Everyone else would rather sell their home..."? At the core there are two factors at play in this decision. One is financial; anyone with the luxury of time will compare a realtor's comps with an ibuyer's offer. The second is certainty; an ibuyer offer is guaranteed, and can be executed without having to show a house over the course of 1 to X months.
It seems to me that certainty has value to some sellers in some situations. Right now, the certainty value of the traditional route is pretty good because the market is on fire. That is not always the case everywhere.
