From the seller’s perspective
The process of selling a home is far easier - first, request a bid from one of the platforms simply by filling out a form and uploading some pictures, next, get an offer, which the seller can take without needing to work around the (human) buyer’s needs or whether the buyer will be able to get a mortgage and close on the purchase (and since the platforms all assume they’ll need to fix up the homes anyway, there’s no pressure for sellers to engage in extra maintenance fixes or complex staging to make the house more appealing for sale).
From the buyer's perspective
The new platforms also make the process of buying simpler, as buyers no longer need to coordinate with sellers, and can simply use the companies’ own apps to open and access a potential new home for a walk through.
