A listing presentation is the material an agent brings to a seller appointment to win the right to list the house. The seller usually interviews two or three agents, and this is the pitch. The marketing person builds it; the agent presents it alone.
What's usually inside: recent comparable sales for that neighborhood, a suggested pricing range, the marketing plan for that specific house (photography, video, where it will be advertised, open house schedule), and a section about the agent's own track record. Post-settlement, most packages now also carry a page or two explaining what the agent does for the fee, because sellers ask about that much more directly than they used to.
Format is usually both. A slide deck on an iPad for the appointment, plus a printed leave-behind so the seller has something on the kitchen counter after everyone's gone. Some providers also do a follow-up email version.
The separate thing agents buy, and the one people mix up with this, is the property marketing package. That's produced after the listing is won: the brochure, the single-property page, the social ads for that house. Presentation wins the listing, marketing package sells the house. When you see $400 a month, that's normally a retainer covering templates, refreshed comps pages, and a set number of new listing packages, and the photography and printing are billed on top.
For you as a buyer, the useful read is that a slick brochure tells you about the agent's marketing budget and nothing about what the house is worth.
