Is $215 of aerial worth it on a 1.4 acre flip, or am I buying pretty pictures

The characteristic is whether the thing you're selling is visible from the street. On a tract house on a 60 foot lot, aerial adds a roof and a picture of the neighbor's pool, and buyers learn nothing. On yours, the entire premium over a comparable house on a small lot is the land, the tree cover and the fact that nobody is looking into the yard. A buyer standing at the curb can't see any of that, and a ground photo of a treeline doesn't convey privacy. One overhead frame does.

So I'd buy it, and I'd buy it for the stills more than the video. Video gets watched by the people already interested. The aerial still is what goes in the third slot of the photo array and stops the scroll while somebody is flicking through 40 listings.

Two things I'd hold you to. Tell the shooter specifically what you want shown, the parcel boundary in relation to the trees and the creek line, otherwise you get a generic orbit at 200 feet that could be any house anywhere. And ask whether they're certified for commercial work and carry insurance, because the ones who aren't are the ones quoting $99 and they'll fly it like a hobby.

On the comps, 3 of 14 tells you the local agents haven't standardized it. That's an argument for doing it, since your listing looks different in the feed. It doesn't tell you it doesn't work, because you can't see the 11 that didn't try. You'll never get the control group on a single flip. At four days of carry the downside is bounded and the information you get is real, so take the bounded loss.
