Both numbers can be right because they're measuring different work. A single residential listing shoot, one visit, a handful of stills and a short video, commonly falls in the $300 to $800 range depending on market and turnaround. Land and development packages are priced per visit and then multiplied, because the site changes.
On a 60-lot subdivision, $4,500 usually decomposes into something like four to eight flight visits across phases (raw ground, after clearing, after roads and utilities, first homes standing), each producing stills plus a short cut, and often an overhead composite of the whole site with lot lines and street names drawn on top. That annotated overhead is the piece with the most marketing life, because a buyer standing on lot 34 can't see what the finished street will look like and an aerial with labels shows it. Some packages also include a mapped output for the engineer or the sales office, which is where the price climbs.
Ask the sponsor for three specifics: how many site visits, how many delivered assets per visit, and who holds the license to reuse the footage after the last lot closes. That last one matters to you as an investor because if the sponsor sells lots in bulk to a builder, the builder will want to use the same aerials and may pay for them a second time.
One thing the marketing framing hides: those same monthly overheads become the cheapest record you'll ever have of grading and drainage on the site, which tends to be worth more later than the video was at launch.
