How long it takes by hand
Count it. One apartment: move the video from the phone, pick 6 photos, put them in order, copy the text from the listing, add the phone number, check the format has not cropped the address in the video, click Share. That is 10 minutes when everything goes smoothly. 30 listings a month is 5 hours, a whole working day of uploading. In practice it does not happen: after three viewings you have no energy, the flat waits until tomorrow, then until next week. With BuzzPost the listing goes to Telegram once for the Facebook groups, and the bot posts it to Instagram as well. You prepare nothing.
